Safety Information

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

WARNING

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

W023

WARNING

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

Important Safety Instructions

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.

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

UW 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 fills 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

Spray-Rinse

The spray-rinse consists of a hose connected from the
hot and cold water inlet spray 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.

UW 35 and 60 washer-extractors include a single drain
valve. UW 80, 100, 125 and 150 models include 2
drain valves. 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.

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

1 dual-speed motor drives the basket’s shaft with a V­belt.

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

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.
