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

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.
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.
Any problems or conditions not understood should be
reported to the dealer, distributor, service agent or the
manufacturer.
IMPORTANT: Ensure that the recommended
clearances for inspection and maintenance
are provided. Never allow the inspection and
maintenance space to be blocked.

in personal injury and/or equipment
damage, and may void the warranty.
SW004
WARNING
Install the machine on a level floor of
sufficient strength. Failure to do so may
result in conditions which can produce
serious injury, death and/or property
damage.
W703
WARNING
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.

open. The machine should not start with the
door open.
b. Close the door without locking it and attempt
to start the machine. The machine should not
start with the door unlocked.
c. Close and lock the door and start a cycle.
Attempt to open the door while the cycle is in
progress. The door should not open.
If the door lock and interlock are not functioning
properly, call a service technician.
3. Do not attempt to operate the machine if any of
the following conditions are present:
a. The door does not remain securely locked
during the entire cycle.
b. Excessively high water level is evident.
c. Machine is not connected to a properly
grounded circuit.
Do not bypass any safety devices in the machine.
NEVER insert hands or objects into
basket until it has completely stopped.
Doing so could result in serious injury.

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.
