W006R2

(continued)

2 F232218

Safety Information

WARNING

To reduce the risk of electric shock, fire, explosion, serious injury or death:

• Disconnect electric power to the washer-extractor before servicing.

• Never start the washer-extractor with any guards/panels removed.

• Whenever ground wires are removed during servicing, these ground wires must be reconnected to ensure that the washer-extractor is properly grounded.

W460

WARNING

Repairs that are made to your products by unqualified persons can result in hazards due to improper assembly or adjustments subjecting you or the inexperienced person making such repairs to the risk of serious injury, electrical shock or death.

W007

WARNING

If you or an unqualified person perform service on your product, you must assume the responsibility for any personal injury or property damage which may result. The manufacturer will not be responsible for any injury or property damage arising from improper service and/or service procedures.

W008

Always contact your dealer, distributor, service agent or the manufacturer about any problems or conditions you do not understand.

Important Safety Instructions

WARNING

To reduce the risk of fire, electric shock, serious injury or death to persons when using your washer, follow these basic precautions:

1. Read all instructions before using the washer-extractor.

2. Refer to the GROUNDING INSTRUCTIONS in the INSTALLATION manual (supplied with your washerextractor) for the proper grounding of the washer-extractor.

3. Do not wash textiles that have been previously cleaned in, washed in, soaked in or spotted with gasoline, drycleaning solvents or other flammable or explosive substances. They give off vapors that could ignite or explode.

4. Do not add gasoline, dry-cleaning solvents or other flammable or explosive substances to the wash water. These substances give off vapors that could ignite or explode.

5. Under certain conditions, hydrogen gas may be produced in a hot water system that has not been used for two weeks or more. HYDROGEN GAS IS EXPLOSIVE. If the hot water system has not been used for such a period, before using a washer-extractor, turn on all hot water faucets and let the water flow from each for several minutes. This will release any accumulated hydrogen gas. The gas is flammable. Do not smoke or use an open flame during this time.

W023E

F232218 3

Safety Information

6. Do not allow children to play on or in a washer-extractor. Close supervision of children is necessary when the washer-extractor is used near children.

7. Before the washer-extractor is removed from service or discarded, remove the door to the washing compartment.

8. Do not reach into the washer-extractor if the wash basket is moving.

9. Do not install or store the washer-extractor where it will be exposed to water and/or weather.

10. Do not tamper with the washer-extractor’s controls.

11. Do not repair or replace any part of the washer-extractor or attempt any servicing unless specifically recommended in the user-maintenance instructions or in published user-repair instructions that the user understands and has the skills to carry out.

12. To reduce the risk of an electrical shock or fire, DO NOT use an extension cord or an adapter to connect the washer-extractor to an electrical power source.

13. Use the washer-extractor only for its intended purpose, washing clothes.

14. ALWAYS disconnect the washer-extractor from its electrical supply before attempting any service.

15. Install the washer-extractor according to the INSTALLATION INSTRUCTIONS. All connections for water, drain, electrical power and grounding must comply with local codes and, when required, be made by licensed personnel.

16. To reduce the risk of fire, textiles which have traces of any flammable substances such as vegetable oil, cooking oil, machine oil, flammable chemicals, thinner, etc. or anything containing wax or chemicals such as in mops or cleaning cloths, must not be put into the washer-extractor. These flammable substances may cause the fabric to ignite.

17. Do not use fabric softeners or products to eliminate static unless recommended by the manufacturer of the fabric softener or product.

18. Keep the washer-extractor in good condition. Bumping or dropping the washer-extractor can damage its safety features. If this occurs, have the washer-extractor checked by a qualified service person.

19. Replace worn power cords and/or loose plugs.

20. Be sure that water connections have a shut-off valve and that fill hose connections are tight. CLOSE the shutoff valves at the end of each wash day.

21. The loading door MUST BE CLOSED any time the washer-extractor is to fill, tumble or spin. DO NOT bypass the loading door switch and permit the washer-extractor to operate with the loading door open.

22. Always read and follow the manufacturer’s instructions on packages of laundry and cleaning aids. Heed all warnings and precautions. To reduce the risk of poisoning or chemical burns, keep them out of the reach of children at all times (preferably in a locked cabinet).

23. Always follow the fabric care instructions supplied by the textile manufacturer.

24. Never operate the washer-extractor with any guards and/or panels removed.

25. DO NOT operate the washer-extractor with missing or broken parts.

26. DO NOT by-pass any safety devices.

27. Failure to install, maintain and/or operate this washer-extractor according to the manufacturer's instructions may result in conditions that can produce bodily injury and/or property damage.

NOTE: The WARNING and IMPORTANT SAFETY INSTRUCTIONS appearing in this manual are not meant to cover all possible conditions and situations that may occur. Common sense, caution and care must be exercised when installing, maintaining and operating the washer-extractor.

Any problems or conditions not understood should be reported to the dealer, distributor, service agent or the manufacturer.

Section 3

Theory of Operation

Starting the Machine

The door lock will not allow a cycle to be started until the door has been closed.

Fill

The operator selects a cycle and starts the machine. Water enters the machine through water valves that are controlled by the microcomputer. As water fills the basket, a column of air is trapped in a pressure bulb and hose. The air pressure continues to increase as the basket flls with water. When the desired water level is reached, the water level switch triggers the microcomputer and the water valves turn off.

A vacuum breaker installed in the inlet plumbing or a shell overflow and air gap prevents the backflow of water.

Supply

The operator can either connect external liquid supplies to the machine or fill the supply dispenser with liquid or dry supplies. The supply dispenser’s nozzles flush the compartments with water at the appropriate times throughout a cycle.

Wash

The basket includes ribs that lift the laundry from the wash water. The laundry then tumbles back into the bath.

Spray-Rinse

The spray-rinse consists of a hose connected from the hot and cold water inlet valves to the center of the door glass. A nozzle on the inside of the door glass produces a fan-shaped spray that disperses water throughout the load.

Drain

UW washer-extractors use a normally-open gravitytype drain system. No pump is used. When the drain valve opens, the perforated basket allows water to drain from it.

In the event of a power failure, the drain valve will open automatically and the machine will drain.

Standard UW washer-extractors include a single drain valve. Dual drain models are available as an option. On dual drain models, the 2 drain valves open and close together.

Extract

A final high-speed extract step removes water from the load, which maximizes drying efficiency.

The door lock system will not allow the door to be opened until the cycle has finished.

In 2-speed and variable-speed models, 1 dual-speed motor drives the basket’s shaft with a V-belt. In 3speed models, 2 motors drive the basket’s cylinder with a V-belt.

UW35, UW60, UW80, UW100 and UW125 models use 2 flange-type bearing that are bolted to the frame. UW150 models use 2 bearings that are held in place by a single cast-iron trunnion that is bolted to the frame.

Section 4

Troubleshooting

WARNING

To reduce the risk of electrical shock, fire, explosion, serious injury or death:

• Disconnect electrical power to the washer-extractor before servicing it.

• Close the gas shut-off valve to the washer-extractor (when applicable) before servicing it.

• Never start the washer-extractor with any guards/panels removed.

• Whenever ground wires are removed during servicing, these ground wires must be reconnected to ensure that the washer-extractor is properly grounded.
