■■Description Construction RS-180 Casing The multi-shell casing, made from aluzinc sheet, is coated on the outside and sealed on the inside with a solvent-free joint sealer. The inner shell, made from aluzinc sheet, is separate from the outer shell, thus preventing thermal bridges. The front ends consist of two screwed, multishell access panels with a flat seal. Integrated in these access panels, there are two filter covers with seals and quick-release fasteners. The high-quality 25 mm thermal insulation is made of polyurethane (PUR, Lambda 0.025 W/mK). The casing is also equipped with sound insulation in the area of the enthalpy recovery system. The interior of the unit is smooth-surfaced (metallic or coated sound insulation surface) and is easily accessed for cleaning. Complies with product standard DIN 4719 (energy, hygiene and sound insulation requirements). Attachment on site is via attachment strips with vibration absorbers.

Hoval HomeVent® RS-180

System for comfort ventilation

■■Description Function RS-180 The outside air fan draws in outside air via the main line. In the first stage, this air is cleaned via an insect filter. In the downstream enthalpy recovery system, the supply air is heated, depending on the temperature, and humidified. The extent to which heat and humidity are recovered is dependent on the temperature and humidity differences between the exhaust air and the outside air as well as on the rotor speed. Then the pre-treated outside air is cleaned by means of a pollen fine dust filter. The supply air is fed into the distribution lines in the perforated plate. The volume flow per distribution line can be adjusted via plug-in plastic panels in the perforated plate. In the downstream silencer, the supply air sound level is reduced. The exhaust fan sucks in the used air via the extract air silencer and the coarse dust filter. The enthalpy recovery system extracts heat and humidity from the air and passes these to the supply air. In the double flush chamber the rotation air is conducted to the exhaust air side. The way the fans are positioned – with overpressure on the outside air side and underpressure on the exhaust air side – no waste air can find its way to the supply air. The waste air is passed on to the exhaust duct. These functions are set via the operator terminal and monitored automatically by the electronics. The outside air and exhaust air fan speeds are regulated independently of each other. The operating point for outside/supply air and extract/exhaust air is set during commissioning with 2 service potentiometers. The electronic controls and the operator terminal feature the following additional functions:

• The speed of the enthalpy recovery system is regulated by the outside air temperature. In this way, the heat and humidity recovery is adjusted automatically. In summer, the speed is adjusted automatically, the heat and moisture recovery efficiency drops towards zero. • The humidity control in the operator terminal adjusts the volume flow. Thus, if the humidity indoors is too high, for instance, more dry air is introduced from the outside. • The fan function is monitored continually. In case of a malfunction, the device is switched to ‘fault’ mode (both fans and the enthalpy recovery system are switched off; signal on the operator terminal). • If the pressure loss caused by the supply air filter pressure drop is too great, the differential pressure monitor displays a signal on the operator terminal.

■■Engineering Relevant norms

• DIN 1946-T6 Controlled mechanical supply and extract air handling for apartments with heat recovery • DIN 4109 Sound insulation in structural engineering • DIN 6022 Ventilation and air conditioning systems – maintenance of air quality and cleaning • DIN 6022 Particulate air filters for general ventilation – determination of the filtration performance One comfort ventilation device is only allowed to be used for one comfort unit. The application limits must be complied with.

Acquiring data and calculating the air throughput

The following data are needed in order to plan the comfort ventilation unit of a set of rooms: • Type and number of rooms • Effective areas of all rooms to be supplied with air and to have used air removed AN [m²] • Effective room height H [m] • Sound pressure outside, in supply air room and in extract air room LP [dB(A)] • Air exchange rate LW [1/h] The air flow capacity must be determined according to the situation at hand. Criteria to be borne in mind include hygienic requirements, the number of people using the rooms and the humidity conditions. Based on DIN 1946-T6.

Calculation of the required air quantity: For reasons of hygiene and due to structural considerations, continuous handling of supply and extract air is required in living areas. Equal quantities of supply and extract air must be provided. Overpressure must be avoided! 1.

Calculation of the occupant-related system supply air volume flow: Minimum air quantity in accordance with DIN 1946-T6: 20-30 m³/h depending on the number of occupants The current edition of DIN 1946-T6 is always definitive for planning.

Calculation of the system extract air volume flow, dependent on the room type. The following extract air volume flows must be ensured with constant ventilation:

Room type (as per DIN 1946T6)

System exhaust air volume flow in m3/h Continuous Ventilation

Bathroom (also with WC)

WC room

Utility room

Kitchenette or kitchen

With regard to the number of persons that can be expected to occupy each room, it is recommended that you also observe the required supply air quantities. These can be weighted for each room. Room type

Required supply air volume flow

Master bedroom (2 people)

40-60 m³/h

Nursery (1 person)

25-30 m³/h

Office/guestroom

25-30 m³/h

The outside air duct and the inlet should be planned in such a way as to avoid the intake of pollutants and smells. The inlet should be at least 2.5 m – 3.0 m above ground and not close to garages or roads with heavy traffic. Sound emissions should be given careful attention. The exhaust outlet should be placed sufficiently far away from the inlet to prevent a short circuit with the outside air intake opening. Calculation of the pressure loss To calculate pressure loss pext, the pressure losses in the air ducts and grilles applying to the planned air flow capacity VA are added together. Where ducts are laid in parallel, the duct with the greatest pressure loss is used in the calculation. Outside air/supply ducts and extract/exhaust ducts are to be considered separately. The external pressure loss must correspond with the range planned (see Technical Data).

The max. air flow rate of the ventilation device must be sufficient for intensive ventilation.

Air ducts and grilles

Depending on the use to which they are put, rooms are divided into supply air, overflow and extract air areas. Rooms are only equipped with both supply and extract air ports in exceptional cases.

■■Engineering Calculation of sound pressure level The sound pressure levels must be calculated for the supply air and extract air rooms. Also, the outdoor requirements must be checked (outside air intake, exhaust outlet). In addition to the sound level data for the components, the project-specific data (e.g. spacing, room damping) are required. It must be ascertained whether it is only necessary to comply with the limit values at the designed air flow rate or also at increased air flow rates and pressures. Setting up the Comfort Ventilation The comfort ventilation unit can be mounted in various different ways (sketches for wall, floor and ceiling installation). For maintenance and repair purposes, the entire comfort ventilation unit, its components and fitted parts must be accessible. When installing on the floor or ceiling, a distance of at least 5 mm must be maintained to the floor or ceiling. The unit is attached using four angle brackets that are screwed onto the face of the device. In case of acoustically critical structures, vibration damper accessories are required. The contact surface (wall, floor, ceiling) must be level. The comfort ventilation unit must not be 'distorted' by the fixation. The comfort ventilation unit should not be installed in humid rooms (such as the laundry room). Observe the dew point temperature as listed in the technical data!

Electronic fittings and arrangement of operator terminal The comfort ventilation unit is supplied ready wired. For connection with the mains supply a 3 m long cable with plug is supplied. A mains socket should be planned close to the installation location. The comfort ventilation unit and operator terminal are connected by an 8 channel CAT 5 patch ribbon cable. The HomeVent® comfort ventilation unit is supplied with a 3 m long cable with an RJ45 plug. An RJ45 socket should be installed close to the comfort ventilation unit on-site. The operator terminal should be positioned according to the following criteria: • Reference room for the humidity control • Operation (setting of volume flow, humidity, party button) • Display (operation, fault) The BG02 operator terminal must be mounted as an on-wall unit. The BG03 operator terminal can be mounted as an on-wall unit or in-wall unit. For this purpose, there are two different models. An RJ45 ribbon cable/plug must be used to connect the operator terminal and the HomeVent®. The supplied cable (3 m) is an 8-pin CAT 5 patch ribbon cable. The cable routed on-site for the remote control should also be a ribbon cable and not a round cable. Heating sources/flue and extract air systems When using ventilation systems together with heating sources, the chimney sweep must be consulted in advance. If ventilation systems are used together with heating sources, approved room-air-independent heating sources should be used. When operating room-air-independent heating sources with comfort ventilation, DIN 1946 part 6 should be followed and alternating and shared operation should be differentiated. -- Alternating operation: Locking through onsite safety equipment. -- Shared operation: Differential pressure monitoring through safety equipment with general building inspection approval. Apart from the relevant local building regulations, the information sheet of the Bundesverband des Schornsteinfegerhandwerkes - Zentralinnungsverband (ZIV - Federal Association of Chimney Sweeps - Central Guild Association) and the Bundesverband für Wohnungslüftung (VfW - Federal Association for Residential Ventilation) should be followed as well.

Hygiene The air ducts and grilles must be accessible for cleaning. Thermal insulation of air ducts The air lines and system components must be insulated with suitable material (e.g. EPDM) if • the dew point is undercut, • heat losses occur (winter), • the supply air is cooled (summer). Lay down the sections of the distribution ducts in the building body only in the heated inner part of ceilings, floors and walls. Cold bridges can cause temperatures to drop below the dew point. AutoCAD® drawings are available for the efficient planning of the Hoval HomeVent®. Air grilles Only heated rooms are provided with comfort ventilation. Unheated areas must not/should not be integrated in the system. IsiPipe air ducts made of EPP • The IsiPipe EPP air ducts are joined via a connecting sleeve. • To ensure tight sealing, the individual sections must be inserted into the sleeve as far as the stop. Tight sealing must be ensured even when individual sections expand or contract as a result of temperature fluctuations. • Temperature of the flowing medium -25°C to + 80°C. • The individual sections can be shortened (e.g. using a knife or a saw). When shortening sections, always cut at right angles and remove any residue from the pipe. Use an assembly device, e.g. pipe clamp. • IsiPipe air ducts made of EPP must be accessible (must not be routed in the cable duct). • IsiPipe air ducts made of EPP must be supported at regular intervals (approx. every 1.5 m) with pipe clamps. • When installing accessory parts with a high dead weight, the weight must be supported so that there is no load on the IsiPipe air duct. • Thermal bridges must be prevented at the junctions between IsiPipe air ducts and pipes or components made of another material, e.g. metal.

Hoval HomeVent® RS-250

System for comfort ventilation

■■Description Function RS-250 The outside air fan draws in outside air through the air intake and transports it to the enthalpy recovery system via the diffuser and the silencer. In the enthalpy recovery system, the supply air is heated and humidified depending on temperature conditions. The extent to which heat and humidity are recovered is dependent on the temperature and humidity differences between the exhaust air and the outside air as well as on the rotor speed. Then the pre-treated outside air is cleaned by means of a pollen fine dust filter. The exhaust fan sucks in the used air via the coarse dust filter. The enthalpy recovery system extracts heat and humidity from the air and passes these to the supply air depending on temperature. The waste air is passed on to the exhaust duct. In the double flush chamber the rotation air is conducted to the exhaust air side. The way the fans are positioned – with overpressure on the outside air side and underpressure on the exhaust air side – no waste air can find its way to the supply air. These functions are set via the operator terminal and monitored automatically by the electronics. The outside air and exhaust air fan speeds are independently regulated to the required speed. In this way, the set volume flow can be maintained independently of pressure loss and the outside air intake and exhaust air volumes remain equal. The electronic controls and the operator terminal feature the following additional functions:

Acquiring data and calculating the air throughput

The following data are needed in order to plan the comfort ventilation of a set of rooms: • Type and number of rooms • Effective areas of all rooms to be supplied with air and to have used air removed AN [m²] • Effective room height H [m] • Sound pressure outside, in supply air room and in extract air room LP [dB(A)] • Air exchange rate LW [1/h] The air flow capacity must be determined according to the situation at hand. Criteria to be borne in mind include hygienic requirements, the number of people using the rooms and the humidity conditions. Based on DIN 1946-T6.

Calculation of the system extract air volume flow, dependent on the room type. The following extract air volume flows must be ensured with constant ventilation:

■■Engineering Calculation of sound pressure level The sound pressure levels must be calculated for the supply air and extract air rooms. Also, the outdoor requirements must be checked (outside air intake, exhaust outlet). In addition to the sound level data for the components, the project-specific data (e.g. spacing, room damping) are required. The need for silencers is indicated by this calculation. It must be ascertained whether it is only necessary to comply with the limit values at the designed air flow rate or also at increased air flow rates and pressures. Setting up the comfort ventilation unit The comfort ventilation unit can be mounted in various different ways (sketches for wall, floor and ceiling installation) since a condensate drain is not necessary. For maintenance and repair purposes, the entire comfort ventilation unit, its components and fitted parts must be accessible. When installing on the floor or ceiling, a distance of at least 5 mm must be maintained to the floor or ceiling. The unit is attached using four angle brackets that are screwed onto the face of the device. In case of acoustically critical structures, vibration damper accessories are required. The contact surface (wall, floor, ceiling) must be level. The comfort ventilation unit must not be 'distorted' by the fixation. The comfort ventilation unit should not be installed in humid rooms (such as the laundry room). The dew point temperature is specified in the technical data.

Thermal insulation of air ducts The air lines and system components must be insulated with suitable material (e.g. EPDM) if • the dew point is undercut, • heat losses occur (winter), • the supply air is cooled (summer). Lay down the sections of the distribution ducts in the building body only in the heated inner part of ceilings, floors and walls. Cold bridges can cause temperatures to drop below the dew point. AutoCAD® drawings are available for the efficient planning of the Hoval HomeVent®.

An RJ45 ribbon cable/plug must be used to connect the operator terminal and the HomeVent®. The supplied cable (3 m) is an 8-pin CAT 5 patch ribbon cable. The cable routed on-site for the remote control should also be a ribbon cable and not a round cable.

Air grilles Only heated rooms are provided with comfort ventilation. Unheated areas must not/should not be integrated in the system.

Only as supply air and extract air line within the heated building envelope.

Hygiene The air ducts and grilles must be accessible for cleaning. In particular, the distributor unit must be properly positioned. The access panel must be accessible!

IsiPipe air ducts made of EPP • The IsiPipe EPP air ducts are joined via a connecting sleeve. • To ensure tight sealing, the individual sections must be inserted into the sleeve as far as the stop. Tight sealing must be ensured even when individual sections expand or contract as a result of temperature fluctuations. • Temperature of the flowing medium -25°C to + 80°C. • The individual sections can be shortened (e.g. using a knife or a saw). When shortening sections, always cut at right angles and remove any residue from the pipe. Use an assembly device, e.g. pipe clamp. • IsiPipe air ducts made of EPP must be accessible (must not be routed in the cable duct). • IsiPipe air ducts made of EPP must be supported at regular intervals (approx. every 1.5 m) with pipe clamps. • When installing accessory parts with a high dead weight, the weight must be supported so that there is no load on the IsiPipe air duct. • Thermal bridges must be prevented at the junctions between IsiPipe air ducts and pipes or components made of another material, e.g. metal.

Hoval HomeVent® RS-500

System for comfort ventilation

■■Description Construction RS-500 Casing The double-shell casing, made from aluzinc sheet, is coated on the outside (casing: dark red RAL 3011, front and back: light red RAL 3000) and sealed on the inside with a solventfree joint sealer. The inner shell, made from aluzinc sheet, is separate from the outer shell, thus preventing thermal bridges. The highquality 30 mm thermal insulation is made of polyurethane (PUR, Lambda 0.025 W/mK). The complete front can be removed, allowing easy access to the smooth interior for cleaning. Attachment on site is via special installation sets including vibration absorbers. Extract air filter (1) The exhaust filter is a coarse filter made from a synthetic filter medium (filter class G4). It has a peripheral seal , is mounted in a filter guide and slides out. This makes changing the filter quick and easy. Electrical fittings (2) The comfort ventilation unit is supplied ready wired. The electrical fittings consist of: -- the mains cable (3 m long) -- the mains plug including fuse -- the electrical box with integrated printed circuit board -- the cable for the operator terminal (3 m) The cables for the internal electrical components are all fitted with plugs. Filter monitoring (3) A differential pressure monitor is installed to monitor the filters. Fans (4,6) The outside air intake fan and exhaust fan each consist of a high-efficiency rear-cambered wheel with special vibration-absorbing bearings and an EC direct current motor with an integrated electronic system. Insect filter (5) The two insect filters each consist of a washable fine-mesh polyamide net with a plastic frame. They are mounted in a filter guide and slide out. Enthalpy recovery system (7) (Rotor with sorption) Both of the enthalpy recovery systems are designed as a removable module. The casing of this assembly is made from aluzinc sheet. The rotor with sorption (aluminium with ionexchange resin and antibacterial coating) is axial- and radial-mounted outside.

The drive is transmitted via the plastic ring with outer cogs, a drive gear wheel, by means of an EC direct current motor with planetary gearing. The speed is controlled and monitored. Double elastic seals are fitted between the enthalpy recovery system and the casing. To avoid rotation air and material transfer, a highly effective double flush chamber has been integrated. Supply air filter (8) The supply air filter is a pollen-fine dust filter made from a synthetic filter medium (filter class F7). It has a peripheral seal , is mounted in a filter guide and slides out. This makes changing the filter quick and easy.

Subject to alterations, 1.8.2013

Hoval HomeVent® RS-500

System for comfort ventilation

■■Description Function RS-500 The outside air fan draws in outside air via the main line. In the first stage, this air is cleaned via an insect filter. In the downstream enthalpy recovery systems, the supply air is heated, depending on the temperature, and humidified. The extent to which heat and humidity are recovered is dependent on the temperature and humidity differences between the exhaust air and the outside air as well as on the rotor speed. Then the pre-treated outside air is cleaned by means of a pollen fine dust filter. The exhaust fan sucks in the used air via the coarse dust filter. The two enthalpy recovery systems extract heat and humidity from the air and pass these to the supply air depending on temperature. In the double flush chamber the rotation air is conducted to the exhaust air side. The waste air is passed on to the exhaust duct. The way the fans are positioned – with overpressure on the outside air side and underpressure on the exhaust air side – no waste air can find its way to the supply air. These functions are set via the operator terminal and monitored automatically by the electronics. The electronic controls and the operator terminal feature the following additional functions:

• DIN 1946-T6 Controlled mechanical supply and extract air handling for apartments with heat recovery • DIN 4109 Sound insulation in structural engineering • DIN 6022 Ventilation and air conditioning systems – maintenance of air quality and cleaning • DIN 6022 Particulate air filters for general ventilation – determination of the filtration performance One comfort ventilation device is only allowed to be used for one utilisation unit. The application limits must be complied with.

Acquiring data and calculating the air throughput

Calculation of the system extract air volume flow, dependent on the room type. The following extract air volume flows must be ensured with constant ventilation:

Room type (as per DIN 1946T6)

System exhaust air volume flow in m3/h Continuous Ventilation

Bathroom (also with WC)

■■Engineering Calculation of sound pressure level The sound pressure levels must be calculated for the supply air and extract air rooms. Also, the outdoor requirements must be checked (outside air intake, exhaust outlet). In addition to the sound level data for the components, the project-specific data (e.g. spacing, room damping) are required. The need for silencers is indicated by this calculation. It must be ascertained whether it is only necessary to comply with the limit values at the designed air flow rate or also at increased air flow rates and pressures. Setting up the comfort ventilation unit The comfort ventilation unit can be mounted in various different ways (sketches for wall, floor and ceiling installation) since a condensate drain is not necessary. For maintenance and repair purposes, the access panel of the comfort ventilation unit must remain accessible (see dimensions). When installing on the floor or ceiling, a distance of at least 10 mm must be maintained to the floor or ceiling. The unit is attached using four angle brackets that are screwed onto the face of the device. In case of acoustically critical structures, vibration damper accessories are required. The contact surface (wall, floor, ceiling) must be level. The comfort ventilation unit must not be 'distorted' by the fixation. The comfort ventilation unit should not be installed in humid rooms (such as the laundry room). The dew point temperature is specified in the technical data.

Hygiene The air ducts and grilles must be accessible for cleaning. In particular, the distributor unit must be properly positioned. The access panel must be accessible! Thermal insulation of air ducts The air ducts must be insulated if • the dew point is undercut, • heat losses occur (winter), • the supply air is cooled (summer). Lay down the sections of the distribution ducts in the building body only in the heated inner part of ceilings, floors and walls. Cold bridges can cause temperatures to drop below the dew point. AutoCAD® drawings are available for the efficient planning of the Hoval HomeVent®. Air grilles Only heated rooms are provided with comfort ventilation unit. Unheated areas must not/should not be integrated in the system.

Heating sources/flue and extract air systems When using ventilation systems together with heating sources, the chimney sweep must be consulted in advance. If comfort ventilation are used together with heating sources, approved room-air-independent heating sources should be used. When operating room-air-independent heating sources with comfort ventilation unit, DIN 1946 part 6 should be followed and alternating and shared operation should be differentiated. -- Alternating operation: Locking through onsite safety equipment. -- Shared operation: Differential pressure monitoring through safety equipment with general building inspection approval. Apart from the relevant local building regulations, the information sheet of the Bundesverband des Schornsteinfegerhandwerkes - Zentralinnungsverband (ZIV - Federal Association of Chimney Sweeps - Central Guild Association) and the Bundesverband für Wohnungslüftung (VfW - Federal Association for Residential Ventilation) should be followed as well.

Prices Our prices shall be ex works, net, excluding packaging. All ancillary costs, e.g. freight, insurance, export, transit, import and other approvals, licenses and authentications, shall be for the account of the buyer. The buyer shall also bear all taxes, charges, customs duty, etc., which are levied in connection with the contract. We shall reserve the right to make price adjustments if wage rates or material prices change between the date of the order confirmation and the contractual performance of the contract. Price increases shall normally be notified three months in advance. We shall be bound to the price stated in the order confirmation for a period of three months after the effective date of the price increase.

Payment terms Unless otherwise agreed in writing, our invoices shall be payable within thirty days with no cash discount. Payment shall be deemed to have been made when the amount in question is at our unrestricted disposal on our account in Swiss Franks. Payment dates shall be observed even if any delays whatsoever occur after shipment of the goods from our works. The buyer shall not be permitted to reduce or withhold payments on account of complaints or counterclaims not recognised by us. Payments shall also be made if insignificant components are missing but usage of the delivered goods is not rendered impossible as a result or if rectification work has to be carried out on the delivery. We shall be entitled to reject rectification of the defect as long as the buyer has not discharged his/its obligations to us. If the buyer fails to comply with the agreed payment dates, default interest shall be paid from the agreed due date without a reminder being issued; the aforesaid interest shall be based on the interest rates prevailing at the domicile of the buyer, but shall be not less than four percent above the current discount rate of the Swiss Central Bank.

Reservation of title Delivered goods shall remain our property (reserved goods) pending full and complete payment of all present and future claims to which we are entitled regardless of their legal cause. This shall also apply if payments are made in settlement of specifically designated claims. The buyer shall be entitled to process and sell reserved goods in the ordinary course of business. If our reserved goods are combined or intermingled with other goods, the buyer shall hereby transfer his/its ownership rights in the new goods or chattels to us upon the conclusion of the contract in the amount of the invoice value of the reserved goods. If the goods are resold by the buyer, he/it shall hereby transfer to us upon the conclusion of the contract with us his/its claims arising from the aforesaid resale in the amount of the invoice value of the reserved goods. If the reserved goods are used by the buyer to perform a works or works delivery contract, his/its claim from the aforesaid works or works delivery contract shall hereby be assigned to us in the same amount and on the same date as for the purchase price claim (Section 6.4). As long as he/it is honouring his/its payment obligations, the buyer shall, however, be authorised to collect his/its resale claim which has been assigned to us. He/it may not dispose of such claims by way of assignment to third parties, however. The empowerment of the buyer to collect the claim may be revoked by us at any time. We shall be entitled to notify third party debtors of the assignment. The buyer shall be entitled to provide us with the necessary information and documents in order to enable us to enforce our rights. If the value of our securities exceeds our total claims by more than 10 %, we shall be obliged to release securities of our choice at the request of the buyer. The buyer shall inform us immediately of any pledge or other impediment to our property enforced by third parties. The buyer shall be obliged to collaborate in measures required to protect our title. He/it shall, in particular, empower us upon the conclusion of the contract to make entries or prior notice of the reservation of title at his/its cost in public registers, books and documents, etc., in accordance with the relevant national laws and shall perform all formalities in this respect. The buyer shall maintain the reserved goods at his/its cost for the duration of the reservation of title and shall insure the said goods against theft, breakage, fire, water and other risks in our favour. He/it shall also take all steps to ensure that our property claims are neither adversely affected nor rescinded. Delivery periods Delivery periods and deadlines stated by us shall be approximate unless we have given an express written confirmation of a deadline as binding. Delivery periods shall be deemed to have been met if notification of readiness to deliver has been sent to the buyer before the end of the delivery period. The delivery period shall be prolonged if details required for the performance of the contract are not received on time or if they are subsequently changed by the buyer. The delivery period shall also be reasonably prolonged if impediments arise which we cannot avert despite exercise of the necessary care (e.g. major operational disruptions, industrial disputes, delayed or defective deliveries, force majeure, etc.). If an agreed delivery date is met by more than 14 days, the buyer shall be obliged to set us a reasonable period of grace. The buyer may only withdraw from the contract if our goods have not been delivered by the end of the said period of grace. Compensation claims for non-performance, delayed performance or any consequential losses shall be excluded unless there was gross negligence on our part. Transfer of risk Unless expressly agreed otherwise in writing, our â&#x20AC;&#x17E;ex worksâ&#x20AC;&#x153; deliveries shall be made in accordance with the international rules on the interpretation of commercial clauses of the International Chamber of Commerce (Incoterms) in the version in force on the date of the order confirmation. The transfer of risk shall be determined by the aforesaid Incoterms. 105

Standard terms and conditions of delivery

Insurance against damages of any kind shall be the responsibility of the buyer. Complaints in connection with the transport shall be immediately notified by the buyer to the last carrier upon receipt of the delivery. If despatch is delayed at the request of the buyer or for any other reasons not attributable to us, the risk shall pass to the buyer on the original date envisaged for the „ex works“ delivery. We shall be entitled to demand payment from this date onwards.

9. Delivery inspection 9.1 The buyer shall be required to inspect deliveries immediately. If the goods do not comply with the order or the delivery note or if visible defects are identified, he/it shall be obliged to notify the aforesaid to us in writing within eight days of receipt. Later complaints shall not be recognised. (Re transport damages, cf. Section 8.4) 10. 10.1

10.2

Assembly and operations The assembly, putting into operation, operation and maintenance of the delivered goods shall be carried out in accordance with our guidelines. They may be executed by our staff or by appropriately trained third parties as agreed with the buyer. If we require a commissioning certificate for certain product groups, warranty claims for the proper functioning of the equipment can only be enforced if a proper hand-over has been documented by a confirmed commissioning certificate received by us within one month of the hand-over.

11. Warranty 11.1 Warranty period 11.1.1 The general warranty period shall be 12 months from the first commissioning but no longer than 18 months from the date on which the relevant goods left our works. If despatch is delayed for reasons not attributable to us, the warranty shall lapse no later than 18 months after notification of the readiness to deliver. The general warranty period shall exclude electrical components for which the warranty period shall be 6 months from the first commissioning but no later than 12 months from the date of shipment from our works. 11.1.2 We refer to Section 11.6.1 with regard to the warranty period for third party products. 11.1.3 The warranty period for components which we have repaired during the warranty period or have delivered as replacement shall be 12 months from the completion of our repair or from the date of the replacement delivery but no longer than the end of a period equivalent to twice the original warranty period as per Section 11.1.1. 11.2 Liability for material, design and workmanship defects 11.2.1 The contractual condition of the goods shall be based on the condition upon the transfer of risk. 11.2.2 Defects shall be notified to us immediately in writing. 11.2.3 We shall be liable for all components which can be shown to have become defective or unusable before the end of the warranty period as a result of defective materials, defective design or defective workmanship, with such components being repaired or replaced ex works immediately at our choice. 11.3 Liability for warranted qualities 11.3.1 Warranted qualities shall only be those which are specifically designated as such in the order confirmation or in the relevant specifications. 11.3.2 The aforesaid assurance shall apply at the latest until the end of the warranty period. If a taking-over test has been agreed with the buyer, the assurance shall be deemed as performed if proof of the relevant qualities is furnished during the aforesaid test. 11.3.3 If the warranted qualities are not performed or only partially performed, the buyer shall be entitled to an immediate rectification. The buyer shall grant us the necessary time and opportunity for this purpose. 11.3.4 If the rectification is abortive or only partially successful, the buyer shall be entitled to a reasonable reduction of the purchase price. If the defect is so serious that it cannot be rectified within a reasonable period of time, and if deliveries or services for the notified purpose are not usable or are only usable to a much lesser extent, the buyer shall be entitled to refuse acceptance of the defective component or to withdraw from the contract if part-acceptance is economically 106

unreasonable. We shall only be obliged to refund amounts which have been paid to us for the components affected by the aforesaid withdrawal. 11.4 Exclusion of liability for defects 11.4.1 Our liability shall exclude damages which cannot be proved to have been sustained as a result of defective material, defective design or defective workmanship. 11.4.2 Damages shall therefore be excluded for example which were caused by – improper work of other persons with regard to planning, site preparation, assembly, operation and maintenance; – plant concepts and designs which do not comply with the latest state of the art; – non-observance of our guidelines for planning, assembly, commissioning, operations and maintenance; – force majeure (e.g. thunderstorms). 11.4.3 The following shall be excluded in particular – corrosion damages (e.g. as a result of aggressive water, unsuitable water treatment, oxygen intakes, emptying the plant over a longer period of time, falling below the dew point, chemical or electrochemical effects, etc.); – damages caused by air pollution (e.g. the accumulation of intense dust, aggressive vapours, etc.); – damages caused by unsuitable equipment and fuels; – damages caused by overcharging, excessive water pressure, scaling, improper electrical connections and inadequate fuse protection. 11.4.4 Components shall also be excluded from the warranty which are subject to natural wear and tear (e.g. burner nozzles, combustion chamber inserts, ignition and monitoring components in contact with fire, fireclay and wall facings, fuses, seals and flexible tubes). 11.5 Commissioning certificate 11.5.1 We hereby draw attention to the due and proper hand-over and - if envisaged - the commissioning certificate in accordance with Section 10.2 as prerequisites for our warranty. 11.6 Deliveries and services of sub-contractors 11.6.1 Our liability for third party products which form a major part of the delivered goods (e.g. warehouse and conveying equipment, burners, measuring and control equipment, electrical components, flue gas and waste water cleaning equipment) shall - if permissible - be limited to an assignment of our claims against the suppliers of the said third party products. 12. Exclusion of further liability 12.1 The buyer shall have no rights and claims for materials, design and workmanship defects or the lack of warranted qualities unless specifically mentioned in Sections 11.1 to 11.6. 12.2 All claims for compensation, reduction in the contract price, rescission of the contract or withdrawal from the contract shall be excluded in particular unless these are specifically mentioned. Under no circumstances shall the buyer have any compensation claim for damages which were not sustained by the delivered goods themselves (e.g. replacement costs, cost for establishing the cause of the damage, expertises, production stoppages, production losses, lost orders, lost profit and other direct or indirect damages). The aforesaid liability exclusion shall not apply in the event of gross negligence on our part. 12.3 The exclusion as per Section 12.2 shall apply for all breaches of contract and all claims of the buyer regardless of why they were lodged from a legal point of view. It shall therefore also apply for a breach of any ancillary obligations (e.g. inadequate advice, etc.). 13. Jurisdiction 13.1 The place of jurisdiction for the buyer and for us shall be Vaduz. We shall be entitled to bring action against the buyer at his/its domicile, however. 13.2 The legal relationship between the parties shall be governed by the substantive laws of Switzerland. The application of the UN convention on contracts for the international sale of goods (CISG) shall be excluded.
