OPERATOR’S GUIDE

GreenEarth is more than an ecologically safe alternative to perc. It is actually better for fabrics. As you know, solvents are only a carrier. Their “strength” is measured by how well they work in combination with additives to dissolve the materials that need to be dissolved without dissolving the materials that need to be protected.

There is actually a complex formula, called the Teas diagram, that explains solvent molecular interactions with complex science like Quantum Mechanics and Cohesive Energy Density. But all that really matters is that GreenEarth’s liquid silicone solvent doesn’t work alone, it is part of a specially designed cleaning system with detergents and machine programs.

The magic of GreenEarth is the unique way it has been designed to work with detergents and the cleaning action of dry cleaning machines to remove stains and soil from fabric fibers without “touching” them. Think of it as having the ability to use a scalpel for stain surgery when everyone else is still using a machete. The “molecular magic” of our cleaning chemistry has been customized with the help of the world’s leading detergent manufacturer, Procter & Gamble.

And through science and l testing, we have perfected the calibration programs to run the machines. Result? The GreenEarth Cleaning system loosens and removes soil particulate from fabrics without degrading or damaging textile fibers. Fabrics are cleaner, fresher, and last longer. That’s why you can tell your customers You’ve never worn anything like it.®

TROUBLESHOOTING: Boiler and Open Flame Influence

Cleaning Programs

Boiler and Open Flame Influence

DO

CAUSES

• • • • •

The thermal degradation of silicone is to SIO2 (sand), H2O and CO2. A fine powder of sand can form on the extreme hot surfaces of a boiler and also on the flame rod or igniter.

Run the “startup program” every morning.

Run wash times of 3-5 minutes fragile, 14-18 minutes regular, 22 minutes heavy soil.

Talk to your detergent rep for specific directions on adding detergent.

If you are using a detergent that is substantive, the mill times must be followed as suggested by your detergent rep. Typically, 5 minutes mill time at .75 oz. to 1.2 oz. per 10 pounds is suggested.

If a program directs the primary separator to the still, it is best to cool the still down first. This is achieved by pumping about 8 seconds of tank 2 or 3 to the still prior to introducing the primary separator to the still.

This may render the burner inoperable or less effective.

CHECK

DO NOT

• •

• •

The boiler room is not constructed with a positive clean air pressure.

Garments are being hung for drying in the boiler room.

REMEDY

Do not shorten mill times from that recommended by detergent rep. If the substantive detergent does not have time to adhere to the textiles, it will adhere to the filtration system resulting in high pressures and poor flow.

Do not over-inject detergent, especially if it is substantive, as this will result in a sticky or tacky feel to garments.

Prevent air that may contain any vapors from entering the boiler room area.

Detergents DO

• • • •

Use only detergents that have been developed specifically for use with GreenEarth.

Use detergents as recommended by the supplier.

Calibrate an injection system monthly. Temperature changes viscosity and, thus, volume. Insulate the bottom of the detergent container.

When changing detergents, purge the cleaning system and injection lines completely before adding the new detergent.

DO NOT

• •

Do not mix anionic and cationic detergents.

Do not use more than the manufacturer’s recommended amount of detergent. This will cause dye bleeding and a tacky feel to garments.

TROUBLESHOOTING: Rings or Halo Marks on Garments

OPERATING: Distillation and Filtration

Rings or Halo Marks on Garments

Distillation

CAUSES

DO

a. Improper spotting. b. Dripping back during drying phase. c. Impurities in the solvent.

• • •

REMEDY

DO NOT

If "a.", use a leveling agent and rerun.

If "b.", check to see if you have any lint collected in the air flow duct entering the drying chamber. If so, remove.

If "c.", it may mean the solvent is being under-distilled and the impurities are showing as rings on the garments. A distillation rate of 10-12 gallons per 100 pounds cleaned is usually adequate.

If the solvent is not distilled, but filters are being used, the filters may need to be changed. With a Kleen-Rite system, a tube will filter approximately 10,000 pounds.

When using standard size cartridges (carbon core), you can expect 1,000 to 1,200 pounds per cartridge.

•

DO

• •

•

29

Never exceed 290°F in the still.

Filtration

•

Operator’s Guide

Make sure the still is cold when running the startup program every morning. Otherwise, you may have flashing, resulting in a boilover.

Distill at least at the recommended rate of 10-12 gallons for every 100 pounds cleaned.

Steam pressure should be between 45 psi to 55 psi to the still. The lower the pressure, the better the quality of distillation. If no distillation is achievable at the lower pressure, it is usually an indication that the still needs additional cleaning.

Use carbon-core cartridge filters with silicone solvent. All carbon filters may also be used, and, due to the minimal amount of free dye, the life of the filter cartridge is quite long.

If using a Kleen-Rite System in lieu of a still, keep in mind that while the clay collects fatty acids and other impurities very well, it will also attract and may eliminate detergent from your system. Therefore, a milling step when detergent is injected is strongly suggested.

If a Kleen-Rite filtration system is used with a cationic detergent that is also substantive, it is important to be able to mill the solvent flow without exposure to the filters for the proper amount of time.

If you are using a Tonsil powder filtration system, the clay will have a very strong affinity for impurities and dye stuffs. Milling is important when the detergent is injected so as not to lose the value of the additive to the activated clay.

OPERATING: Maintenance Procedures

TROUBLESHOOTING: Wrinkles or Shrinkage

Start Up Program

Wrinkles or Shrinkage

DO

CAUSES

•

• • • •

Run a "startup program" or “good morning program,” especially on Mondays. Many operations run this program every day. Water may fall out overnight. Because of the density of silicone, the water drops to the bottom of the tank and must be removed every morning before the machine is operated. The startup program will normally remove just a few gallons off the bottom of the tanks into the still.

Run the startup program with a cold still.

Once a week, watch the startup program to make sure that it is operating properly.

Be sure to pull first from the working tank, then from the tank that collects recovery solvent from the separator, and last from the holding tank (if there are three tanks).

This is so that the pump manifold is purged with clean solvent.

Be sure to empty the primary separator to the still. The primary separator collects the initial distillation and thus the low-end boilers.

This is most often caused by the presence of moisture in the form of either water or steam.

CHECK

• • • • •

Leaking steam coil.

Leaking water coil.

Excess pre-spotting.

Excess humidity.

Free water or extremely hydrated solvent.

REMEDY Once the source has been identified, remedy as appropriate.

DO NOT

• •

Do not discontinue the startup program. Without this program, bacteria and odor will develop very quickly.

Do not warm up the still before running the startup program.

Filtration System DO

• • •

If a spin disc system is used, it must be spun and dropped to the still based on frequencies suggested by the manufacturer. If the latter is done, it is suggested that a cartridge housing be placed post-spin and pre-wheel to maximize quality.

Periodically observe filter pressure and flow rates by filling an empty wheel and timing the fill. There should be a wheel change in less than 60 seconds.

If filter pressure becomes too high, refer to the operating manual for your machine for instructions on how to proceed.

TROUBLESHOOTING: Poor Solvent Mileage (Cont’d)

OPERATING: Maintenance Procedures

Poor Solvent Mileage (Cont’d)

Lint Filters

REMEDY

DO

Reference “Extended Dying Time” on page 21.

• •

If completion of the dry cycle is determined by temperature, make sure the temperature is set properly.

Clean lint filters every load.

Wash lint filters on a weekly basis or as instructed in the operating manual for your machine, as follows: Remove as much lint by hand as you can. Then wash with a pH neutral detergent and a soft-bristled brush. Air dry.

DO NOT

•

If the completion of the dry cycle is determined by flow sensors, check for lint build up.

Make sure the setting is correct. Keep in mind that on a flow sensor the 6:00 position is the most dry. Most are at a setting of 4:00-5:00 or 7:00-8:00.

•

Do not wash the filters in the machine or in the silicone solvent. This will cause clogging of the filter media. This will result in long dry cycles due to the restricted air flow.

Do not dry the filters in the cleaning machine or dryer. This may cause shrinkage and unnecessary mechanical action.

Watch for lint build up on the sides of the machine near the openings or the residue left as vapors dry and soap remains.

Water Separator DO

• •

• •

Clean and maintain water separator at the intervals recommended in the operating manual for your machine. This should be done at least once a week.

Use the following process to clean the water separator: 1. Empty as much water from the separator as possible. Move the remaining silicone solvent to the still.

2. Wipe the tank dry with terrycloth towels.

3. Saturate a small terrycloth towel with Lysol liquid disinfectant (do not use the concentrated type) and wipe surfaces of tank with the towel, leaving the tank damp.

4. Use a separate collection vessel for each water source. This must be emptied at the beginning of the shift and, therefore, you can monitor that water is being evacuated from each source.

If it is determined that no or less water is being recovered from a specific separator, then determine if the sensor is working or if there is blockage in the drain system.

It is also suggested that you measure and record the volume of water collected from the machine on a daily basis.

DO NOT

•

Operator’s Guide

27

When cleaning a feed tank for the vacuum pump, do not use Lysol. It is natural for water to collect in the vacuum feed tank as it is being derived from the RH in the air of the still.

Drain water prior to operating the vacuum.

TROUBLESHOOTING: Poor Solvent Mileage

OPERATING: Maintenance Procedures

Still Residue

Poor Solvent Mileage

DO

With a dry-to-dry system, customary mileage is up to 1,400 pounds per gallon. With a transfer system, customary mileage is up to 1,000 pounds per gallon.

• • • •

Drain still residue as instructed in the operating manual for your machine. Most sludge pumps will not pump the NVR due to the dryness of the NVR. Drain the still residue regularly. Otherwise, this may cause slow distillation.

If your NVR is very liquid in appearance, it is likely that you are not distilling to the extent and capability of the still. Most often this is the result of not cleaning the still sufficiently or frequently enough.

Clean the still as instructed in the operating manual for your machine.

Lubrication System

At least once a week, at a time when the still is empty and all solvent that is normally in the system is in the system, calculate mileage as follows: 1. Confirm still is empty.

2. Purge the air out of the filter housing to be sure there are no air pockets.

3. Move all solvent to a preset level on all but one tank.

4. To measure the change in that one tank, you will need to know: a. The level from the week before. b. How much solvent has been added in the past week. c. How much solvent may have been used for sampling. d. The volume of gallons per vertical inch on the tank.

5. Using the above information, calculate the number of gallons of solvent consumed.

6. Divide the pounds cleaned during the week by the number of gallons consumed. This is your weekly mileage.

7. Keep a log book of accumulated poundage and solvent consumption, and do monthly, quarterly and annual calculations based on the totals.

DO

• • •

Periodically, check to make sure that the lubrication system is functioning.

Refer to the operating manual for your machine to determine the type of oil to add.

Add oil as necessary. If there is no consumption of oil, the system is not operating and should be corrected as soon as possible. Without lubrication the pneumatic valves will begin to malfunction.

CAUSES a. Improper drying.

Air Chambers

b. Inadequate distillation.

DO

•

c. Vapor leak.

Clean the lint out of all air chambers regularly, including the air chamber going into the wheel. Build-up of lint will affect airflow, as well as become a source of odor. It will also extend drying time.

DO NOT

CHECK

•

To check for improper drying, weigh "dry" load then re-dry and weigh again. The weight of the solvent is 7.9 pounds per gallon.

Do not forget to remove lint regularly from the air chamber going into the wheel.

The consistence of the NVR being removed should be almost dry (not running).

TROUBLESHOOTING: Odor in the Separation System

OPERATING: Solvent, Spotting Chemicals and Leveling Agents

Odor in the Separation System

Solvent

CHECK

DO

•

Drain the liquid from the vessel. The drain is on the bottom of the vessel, as is the water.

Water is much more likely to hold the odor than the solvent. If there is an odor, identify the source of the condensed liquids and determine if:

•

Check for odor daily. If there is even a hint of odor, refer to Troubleshooting Guide.

ACT IMMEDIATELY -- DO NOT LET IT GO! Check solvent clarity daily. If cloudy, refer to “Cloudy Solvent”, page 19.

DO NOT

a. The odor is only in the vessel, or

•

Do not ignore even a very slight odor. This is always a sign of a problem in the system.

b. The source of the odor is the condensing coils prior to the separator, or c. The water sensors are not functioning.

Spotting Chemicals and Leveling Agents:

REMEDY

DO

If "a.", wipe the vessel out with a rag saturated in Lysol liquid disinfectant. To prevent reoccurrence, drain the vessel and clean more frequently.

If "b." and the source is the still recovery, check the stanchion pipe in the condenser coil to be sure that there is no blockage and that it drains freely. If not, contact your serviceman or machine manufacturer's representative. Keep in mind that a boilover may also result in odor.

(See "Boilover," page 18, to determine if a boilover has occurred.)

• • • • • •

DO NOT

If "b." and the source is the dryer recovery head, refer to “Odor in the Wheel" on page 23 and follow those steps.

•

If "c.", empty all water-out vessels on a daily basis to confirm that water is being sensed and also ejected. Some pneumatic valves have been equipped with air throttling valves to slow the action of the valve. These are prone to clogging. Refer to the machine manual as to the best method to confirm the functioning of the water sensing system.

• • •

Confirm that when the water is sensed and the valve opens that the water actually leaves the vessel. Clogging of both fittings and drain tubes can happen.

Operator’s Guide

25

Use spotting chemicals developed specifically for use with GreenEarth.

Use POG that has been developed specifically for use with GreenEarth.

Flush and dry all spotting chemicals before the garments go into the wheel.

Use only leveling agents that have been developed specifically for use with GreenEarth.

Use only leveling agents that have been developed for use with the specific detergent you are using.

Refer to the GreenEarth Cleaning website for a list of recommended spotting agents and additives.

Do not introduce anything into the cleaning system that contains hydrocarbons, perchloroethylene or trichloroethylene. These chemicals may cause odors or waste disposal issues. Remember: Whatever you introduce into the system ultimately ends up in your waste streams.

Do not use POG that has not been approved by GreenEarth as effective, environmentally friendly, and compatible with silicone.

Do not use an anionic leveling agent with a cationic detergent or vice versa.

Do not mix detergents and leveling agents from different manufacturers.

Operator’s Guide

SPOTTING GUIDE: Introduction The following Standard Operating Practices (SOPs) are intended to provide a guideline for proper spotting techniques when using GreenEarth silicone solvent. These techniques are similar to those advocated by the International Fabricare Institute (IFI) and Neighborhood Cleaners Association (NCA). It is recommended that either IFI or NCA be consulted for additional spotting procedures and techniques.

It is important to only use detergents or additives that are GreenEarth approved. As a part of the approval process, detergents and additives are evaluated as to their influence on the characteristics of silicone. A list of the approved detergents and additives can be found on GreenEarth’s website (www.greenearthcleaning.com).

TROUBLESHOOTING: Odor in the Tanks

Odor in the Tanks CHECK Pump the solvent into an empty wheel to about 1/3 of the normal operating level. (Since the source to the pump is the bottom of the tank, the probability of pulling water, and thus the source of the odor, is very high.) Agitate the wheel and then shut down the machine. Then open the wheel and check for odor. If there is an odor, determine whether the source is: a. In the recovered solvent tank. b. In the working tank.. c. In the retex sizing tank.

Additives are chemical agents that are introduced into the cleaning machine. Approval is not needed if chemical agents are used locally on the spotting board then flushed prior to textiles being placed in the machine.

REMEDY If "a.", the likely source of the odor is the separation system or the startup program has not been followed. The best remedy is:

Since dry cleaning programs may change based on the model of machine in operation and detergent used, it is best to consult the representative of the cleaning machine and the representative of the chemical company.

1.

2.

This SOP is explicitly written for an experienced spotter. One who has had experience in spotting and the processing of textile garments will best understand the terms and explanations.

3.

Allow the tank to settle overnight and then pump the contents to a cold still. If the still cannot hold the volume, then temporarily pump the remainder to the wheel.

Open the sight glass. If there is odor, dry out the tank with rags and allow to air dry for a few hours. Then wipe out the tank with a towel saturated in Lysol disinfectant.

Start the still slowly, as there is probably water present. Then inspect the returning solvent to confirm that the odor is gone.

If "b.", the likely source is that the Startup Program has not been followed, allowing water to stagnate. Another possibility is that the cooling coils may have a slight water leak. If so, the coils can be hydrostatically tested.

If "c.", the Startup Program may not have been followed. If the tank is being used for a bath process, then there may be moisture that has been allowed to stagnate in the tank. Follow remedy under "a." above.

Note: Although unlikely, another source of the odor may be a leak in the tank cooling coil, which would return an overabundance of water through the separation system. .

Odor

SPOTTING: Stain Removal Tools and Equipment

Stain Removal Tools and Equipment

Any time a solvent has a water interface, there is always the possibility for the formation of bacteria and the resulting odor. While it is true the GreenEarth silicone is not a feedstock for bacteria, the potential for a water interface does exist, and thus there is a potential for bacteria to develop if your system is not properly maintained.

WHITE TOWELS

If allowed to stagnate, the water interface layer can form bacteria, and thus odor, due to bacterial feeding on the fatty acids, sugars and other impurities that have been removed from the textiles being cleaned and are thus present in the water interface layer.

SPOTTING BRUSHES

• • • •

Therefore, at the first sign of odor, IT IS IMPORTANT TO ACT IMMEDIATELY. DO NOT LET THE ODOR PERSIST. Bacteria doubles every 32 minutes at 72°F and the odor may be difficult to remedy if it is not dealt with immediately.

• • • • • •

Used as an absorbent for either solvent or water.

Used to absorb stains as they are flushed from a fabric.

Used to test or indicate dye bleeding from fabric.

Used to clean spotting board surface.

Two colors of brushes are used: Black with agents on the dry side.

White with agents on the wet side.

At least two brushes per color should be available with different bristle hardness.

A padded spotting brush is useful.

Brushes are used for tamping. The mechanical action aids in the removal of stains.

SPATULA (BONE)

SPOTTING: The Spotting Board and Organizing Chemicals

TROUBLESHOOTING: Insufficient Soluble Soil Removal

The Spotting Board

Insufficient Soluble Soil Removal

The spotting board has a flat working surface where most tamping and mechanical action occurs. The nose or front of the board has a Teflon cover and has the ability to vacuum when activated by a foot pedal.

CAUSES a. Insufficient wash time. b. Insufficient solvent flow.

A flat surfaced sleeve board allows for work on cuffs and small areas of garments. It, too, has a nose that has a vacuum when activated.

c. Insufficient solvent level.

REMEDY

The board is equipped with three pedals that activate steam. Additionally, the board has a spotting gun that creates a vacuum and/or emits air. The preferred gun has a venturi ability, coupled to a supply vessel allowing for the agent to be atomized with the air or steam flow.

At the rear of the spotting board is a storage area for spotting agents, brushes and bowls.

If "a.", and the items cleaned are unusually soiled, then extend the wash time and pump the heavily-soiled solvent directly to the still. It may be better to identify these runs and mill them only since you are not filtering the oil but solubilizing it and there is not a reason to contaminate the solvent in the filter. Run times for traditional cleaning are between 14 and 18 minutes. For heavy soil, the run time is 22 minutes.

Configuration of Chemical Agents on Spotting Board If "b.", be sure the flow rate is at one change per running minute during the wash cycle.

TROUBLESHOOTING: Extended Drying Time

SPOTTING: Types of Stains

Extended Drying Time

Types of Stains

CAUSES

There are four basic types of stains that require different techniques and agents.

Most common cause of long drying times is restricted air flow.

SOLVENT SOLUBLE STAINS

a. May be retention of the solvent after extraction.

These stains are typically oils, greases and waxes. Because the Kari-Butanol (KB) factor of GreenEarth is low it may be necessary to use an additional POG (paint, oil and grease remover) agent on the board prior to cleaning. In most cases this will not be necessary. The low KB value found in GreenEarth is what allows previously non-dry cleanable garments to be processed. The typical cleaner no longer has to wholesale as many items as cleaners using other solvents.

b. May be the collection of liquid in the bottom of the button trap and the need to re-recover the solvent. c. May be caused by overloading. Most manufacturers recommend loads at 80% of listed size; i.e., run 48 pounds in a 60-pound capacity machine.

REMEDY If "a.": Clean the air filter system. The filters must be washed on a daily basis with water and a neutral soap. Silicone solvent has a tendency to coat the filters and not allow the air to flow at a full rate. The use of the neutral soap is critical. Air dry the filters and return to the air system.

WATER-SOLUBLE STAINS

If "b.": Confirm that extraction times and speeds are as recommended by the manufacturer.

These stains are typically sugars, salts, food, beverages and perspiration. These stains normally require pre- or post-spotting. The removal of these stains is augmented with the use of detergents and/or hydrated solvent. After cleaning in GreenEarth, wet-side stains can simply be blown out on the board.

INSOLUBLE STAINS

If "c.": Confirm that the pump is programmed to intermittently pump out the button trap during the dry cycle (if needed).

These stains are particle stains such as carbon, dust and sand. The low surface tension of GreenEarth’s silicone helps penetrate and remove these stains. Insoluble stains may also require some mechanical action (tamping). While cleaning, it is important to have a high flow rate of solvent and ability to suspend or deposit these particles away from the garments.

SOLUBLE STAINS IN CHEMICAL AGENTS These stains are made up of products like nail polish, lipstick, rust, paints, glues and albumin.

It is necessary to use chemical agents to solubilize these stains. After working on the spotting board, it is important to flush the stain and chemical on the board prior to introducing the garment into the cleaning wheel. This insures the cleaning machine continues to operate with the most environmentally safe system.

TROUBLESHOOTING: Dye Bleeding

SPOTTING: Oil, Grease, Fat and Wax Stains

Stain Removal Agents and Procedures

Dye Bleeding

OILS, GREASES, FATS AND WAXES INCLUDING OXIDIZED AND NON-OXIDIZED OILS

CAUSES Dye bleeding is never caused by the GreenEarth solvent, regardless of the temperature of the solvent.

•

The primary cause of dye bleeding is an overcharge of the detergent. If you are using too much detergent this will cause dye bleeding.

• •

Another common cause is excess moisture somewhere in the system.

•

Free water can also cause or add to dye bleeding.

VDS POG PROCEDURE FOR REMOVAL OF STAINS 1.

2.

3.

4.

5.

6.

7.

Apply VDS to the stained area (this allows other agents to be flushed easier and acts as a wetting agent).

Tamp.

Flush with VDS. Apply VDS and POG if stain remains. If stain is hard, allow chemical to saturate and remain on stain for softening.

Tamp.

Flush with VDS. Re-clean if necessary.

Another source is garments with fugitive dyes, which may be unique to only one garment. Some unusual items may have been home-dyed or left with fugitive surface dyes that any amount of agitation will cause to run.

REMEDY Titrate detergent and adjust volume of accordingly. The most common volume of detergent is .75% to .8% by volume.

If an injection system is in use, the most common volume of detergent is 1 to 1.3 oz. per 10 pounds of cleaning.

Rerun the affected garments in a load by themselves. In very stubborn cases, it may be necessary to wash out the dye.

TROUBLESHOOTING: Cloudy Solvent

SPOTTING: Nail Polish, Plastic, Some Dye (Dry Side) Stains

Cloudy Solvent

Stain Removal Agents and Procedures

CAUSES

NAIL POLISH, PLASTIC, SOME DYES (DRY SIDE)

Most often cloudy solvent is an indication of the presence of moisture. If a cationic detergent is being used, it will most likely contain moisture, which could make the solvent appear cloudy.

VDS

Suspended air in the solvent may also cause a cloudy appearance.

POG

CHECK

AMYL ACETATE

First, identify the vessel containing cloudy solvent. This may help you logically determine the source of the moisture.

PROCEDURE FOR REMOVAL OF STAINS

To check for moisture in the solvent, put a sample of the cloudy solvent in a clear glass and add salt or anionic detergent. If that clears it up, then there is excess moisture in the solvent.

Check all sources of moisture, including: • Excess detergent.

• Improper spotting.

• Leaking steam coil.

• Leaking cooling coil.

• Boilover.

Apply VDS to the stained area.

Tamp or use Spatula (use only necessary mechanical action).

If stain remains and fabric is safe, apply VDS and POG. Apply amyl acetate to stain area.

Repeat steps 1-4 as needed.

Flush with VDS. If steps 1-4 do not remove the stain, confirm fabric is safe for acetone and then apply acetone.

Flush with VDS. Re-clean if necessary.

After identifying source of moisture, make necessary adjustments.

SPOTTING: Tannin and Caramelized Sugar Stains

Stain Removal Agents and Procedures

Boilover

TANNIN STAINS AND CARAMELIZED SUGAR STAINS

IF YOU SUSPECT A BOILOVER, DO NOT RUN THE MACHINE UNTIL REMEDIED! A major indicator of a boilover is the presence of a murky (sometimes brown) liquid in the separator after the still condensation coil. If not identified early, this same liquid can also contaminate the recovery tank.

NSD TANNIN OR ACETIC ACID

CAUSES a. May be the presence of moisture. If the still is not fractional by design, the early boilers may cloud or cause the solvent to become murky. b. May be pumping solvent into a pre-heated still without cooling down the still first (flashing).

GENERAL FORMULA

c. May be caused by overfilling the still.

RUST REMOVER

d. May be too much soap or prespotter. e. Water may be entering the system from a different source.

Flush thoroughly with steam Apply NSD and tamp. Then, flush with steam.

If stain remains use tannin formula or acetic acid 28%.

Tamp or flush with steam.

If stain remains, use general formula; tamp and flush with steam.

If traces remain, use rust remover. While using rust remover, be sure to use gloves, eye protection and a towel to protect the surface of the spotting board. Flush thoroughly.

As a last resort, apply an oxidizing bleach to the stain after testing the fabric.

REMEDY Determine the reason for the presence of moisture and remedy it. Empty the separator, clean, and allow the solvent to settle out. This will occur over a period of time (1 to 1½ days). Then reintroduce the solvent to the still.

If the tank is contaminated, it may be necessary to clean the tank, as well (see "Tanks”, page 24).

After re-initiating distillation, the first solvent recovered may appear cloudy (in a nonfractional still). Drain the initial cloudy collection until clear. Reintroduce solvent to the still.

Check the still condenser coils and the drying coils.
