relating to the operation of this machine follow.

Danger indicates the presence of a hazard

that will cause severe personal injury,

death or substantial property damage if

the danger is ignored.

DANGER

Safety Information

F232204R5

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.

2. Refer to the GROUNDING INSTRUCTIONS in

the INSTALLATION manual (supplied with your

washer) for the proper grounding of the washer.

3. Do not wash textiles that have been previously

cleaned in, washed in, soaked in or spotted with

gasoline, kerosene, waxes, cooking oils, dry-

cleaning 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, 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.

6. Do not allow children to play on or in a washer.

Close supervision of children is necessary when

the washer is used near children.

7. Before the washer is removed from service or

discarded, remove the door to the washing

compartment.

8. Do not reach into the washer if the wash drum is

moving.

9. Do not install or store the washer where it will be

exposed to water and/or weather.

10. Do not tamper with the controls.

11. Do not repair or replace any part of the washer 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 to an electrical power source.

13. Use the washer only for its intended purpose,

washing clothes.

14. Never wash machine parts or automotive parts in

the machine. This could result in serious damage

to the basket.

15. ALWAYS disconnect the washer from its

electrical supply before attempting any service.

16. Install the washer 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.

17. 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.

These flammable substances may cause the

fabric to ignite.

18. Do not use fabric softeners or products to

eliminate static unless recommended by the

manufacturer of the fabric softener or product.

19. Keep the washer in good condition. Bumping or

dropping the washer can damage its safety

features. If this occurs, have the washer checked

by a qualified service person.

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:

20. If the supply cord is damaged, it must be replaced

by a special cord or assembly available from the

manufacturer or its service agent.

21. Be sure that water connections have a shut-off

valve and that fill hose connections are tight.

CLOSE the shut-off valves at the end of each

wash day.

22. The loading door MUST BE CLOSED any time

the washer is to fill, tumble or spin. DO NOT

bypass the loading door switch and permit the

washer to operate with the loading door open.

23. 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).

24. Always follow the fabric care instructions

supplied by the textile manufacturer.

25. Never operate the washer with any guards and/or

panels removed.

26. DO NOT operate the washer with missing or

broken parts.

27. DO NOT bypass any safety devices.

28. Failure to install, maintain and/or operate this

washer according to the manufacturer's

instructions may result in conditions that can

produce bodily injury and/or property damage.

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.

Any problems or conditions not understood should be

reported to the dealer, distributor, service agent or the

maintenance space to be blocked.

This machine must be installed, adjusted,

and serviced by qualified electrical

maintenance personnel familiar with the

construction and operation of this type of

machinery. They must also be familiar

with the potential hazards involved.

sufficient strength. Failure to do so may

result in conditions which can produce

serious injury, death and/or property

damage.

Be careful around the open door,

particularly when loading from a level

below the door. Impact with door edges

can cause personal injury.

SW025

CAUTION

Never touch internal or external steam

pipes, connections, or components.

These surfaces can be extremely hot and

will cause severe burns. The steam must

be turned off and the pipe, connections,

and components allowed to cool before

the pipe can be touched.

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

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.

In 2-speed and variable-speed models, 1 dual-speed

motor drives the basket's shaft with a V-belt. In 3-

speed models, 2 motors drive the basket's cylinder

with a V-belt.

18-60 pound capacity models use 2 bearings that are

held in place by a single cast-iron trunnion that is

bolted to the frame. 80 and 125-pound capacity

models use 2 flange-type bearing that are bolted to the

frame.

Drain

Cabinet Hardmount washer-extractors use a normally

open gravity-type 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.

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.
