20oC DB (70oF DB) 7oC DB (45oF DB) 6oC WB (43oF WB) Piping Length: 5 Meters, Piping Lift: 0 Meter 2. The sound pressure level is based on following conditions. 1 Meter from the unit service cover surface, and 1.5 Meters from floor level. The above data is based on the cooling mode. In case of heating mode, the sound pressure level increases by approximately 1~2 dB. Voltage of the power source is 380V or 220V. In case of the power source of 415V, the sound pressure level increases by approximately 1 dB. 3. The outdoor units for each power supply, 380-415V/50Hz, 380V/60Hz and 220V/60Hz are different. Therefore, check the required power supply when ordering. 4. In case of the outdoor unit for 220V/60Hz, the motor output is 0.38(6)x1+0.275(6)x2.

(7) Actual Capacity In the case of the example of page 10, the total indoor horsepower is 28HP (=2.0HP+2.5HPx2+3.0HP+4.0HPx2+5.0HPx2). Therefore, the outdoor unit capacity at the nominal temperature which is selected from the “Capacity Characteristic Curve” is 71.7kW (61,614 kcal/h) at the cooling operation, 80.5kW (69,217 kcal/h) at the heating operation under nominal conditions. 1.

8.11 Dryer for Field-Piping The refrigeration oil for the RAS-FSG1 series outdoor units easily absorbs moisture. Therefore, it is required to perform sufficient vacuum pumping and to use a dryer in the liquid line, in Item

order to remove moisture in the field-supplied piping. The following dryer kits are available as optional accessories.

Wo: Outdoor Unit Ref. Charge (kg) 25.0 28.5

NOTES: 1. Wo is outdoor unit ref. charge before shipment. 2. Additional refrigerant charge is 1 kg/unit of 8HP and 10HP indoor unit. Additional refrigerant charge of less than 8HP indoor units are not needed.

1. Maximum Permissible Concentration of HFC GAS: The refrigerant, R407C, charged in the SET-FREE FSG1 system, is an incombustible and non-toxic gas. However, if leakage occurs and gas fills a room, it may cause suffocation. The maximum permissible concentration of HFC gas, R407C in air is 0.3kg/m3, according to the refrigeration and air conditioning facility standard (KHK S 0010) by the KHK (High Pressure Gas Protection Association) Japan. Therefore, some effective measure must be taken to lower the R407C concentration in air below 0.3kg/m3, in case of leakage. 2. Calculation of Refrigerant Concentration (1) Calculate the total quantity of refrigerant R (kg) charged in the system connecting all the indoor units of objective rooms. (2) Calculate the room volume V (m3) of each objective room. (3) Calculate the refrigerant concentration C (kg/m3) of the room according to the following equation. R: Total Quantity of Charged Refrigerant (kg) V: Room Volume (m3) = C: Refrigerant Concentration â&#x2030;¤ 0.3 (kg/m3) If local codes or regulations are specified, follow them. <Example> British Standard BS4434 1989 R22 Commercial office Building Class D Occupancy C=0.17 (kg/m3)

15. STANDARD SPECIFICATIONS (Refer to the Technical Catalog I, SP1-K03Q.)

16. CAUTION ON REFRIGERANT LEAKAGE 16.1 Maximum Permissible Concentration of HFC Gas The refrigerant R407C, charged in the SET-FREE FSG1 system, is an incombustible and non-toxic gas. However, if leakage occurs and gas fills a room, it may cause suffocation. The maximum permissible concentration of HFC gas, R407C in air is 0.3 kg/m3, according to the refrigeration and air conditioning facility standard (KHK S 0010) by the KHK (High Pressure Gas Protection Association) Japan. Therefore, some effective measure must be taken to lower the R407C concentration in air below 0.3 kg/m3, in case of leakage.

16.2 Calculation of Refrigerant Concentration (1) Calculate the total quantity of refrigerant R (kg) charged in the system connecting all the indoor units of rooms to be air-conditioned. (2) Calculate the room Volume V (m3) of each room. (3) Calculate the refrigerant concentration C (kg/m3) of the room according to the following equation. R: Total Quantity of Charged Refrigerant (kg) V: Room Volume (m3)

= C: Refrigerant Concentration â&#x2030;¤ 0.3 (kg/m3)

16.3 Countermeasure for Refrigerant Leakage According to KHK Standard The facility shall be arranged as follows referring to the KHK standards, so that the refrigerant concentration will be below 0.3 kg/m3. (1) Provide a shutterless opening which will allow fresh air to circulate into the room. (2) Provide a doorless opening of 0.15% or more size to the floor area. (3) Provide a ventilator, linked with a gas leak detector, of 0.4 m3/min. or more ventilating capacity per Japanese Refrigeration Ton (= compressor displacement m3/h / 9.8) of the air conditioning system utilizing refrigerant R407C.
