Safety Information
Explanation of Safety Messages
Precautionary statements (“DANGER,” “WARNING”
and “CAUTION”), followed by specific instructions,
are found in this manual and on machine decals. These
precautions are intended for the personal safety of the
operator, user, servicer and those maintaining the
machine.
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:
W023
DANGER
DANGER indicates the presence of a
hazard that will cause severe personal
injury, death, or substantial property
damage if the danger is ignored.
WARNING
WARNING indicates the presence of a
hazard that can cause severe personal
injury, death, or substantial property
damage if the warning is ignored.
CAUTION
CAUTION indicates the presence of a
hazard that will or can cause minor
personal injury or property damage if the
caution is ignored.
Additional precautionary statements (“IMPORTANT”
and “NOTE”) are followed by specific instructions.
IMPORTANT: The word “IMPORTANT” is used
to inform the reader of specific procedures where
minor machine damage will occur if the procedure
is not followed.
NOTE: The word “NOTE” is used to communicate
installation, operation, maintenance or servicing
information that is important but not hazard
related.
1. Read all instructions before using the washer.
2. Refer to the GROUNDING INSTRUCTIONS in
the INSTALLATION manual 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, drycleaning solvents, or other flammable or
explosive substances as 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
washing machine or combination washer-dryer,
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 the washer.
Close supervision of children is necessary when
the washer is used near children. This is a safety
rule for all appliances.
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.

the power cord by grasping the plug, not the cord.
16. Install the washer according to the
INSTALLATION INSTRUCTIONS. All
connections for water, drain, electrical power and
grounding must comply with local codes and be
made by licensed personnel when required.
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 and
cleaning cloths, must not be put into the washer.
These flammable substances may cause the
fabric to catch on fire by itself.
18. Do not use fabric softeners or products to
eliminate static unless recommended by the
manufacturer of the fabric softener or product.
19. Keep washer in good condition. Bumping or
dropping the washer can damage safety features.
If this occurs, have washer checked by a qualified
service person.
F232215
20. If 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 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. Loading door MUST BE CLOSED any time the
washer is to fill, tumble or spin. DO NOT bypass
the loading door switch by permitting the washer
to operate with the loading door open.
23. Always read and follow manufacturer’s
instructions on packages of laundry and cleaning
aids. Heed all warnings or 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 which can
produce bodily injury and/or property damage.
NOTE: The WARNINGS 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, or operating the washer.
Any problems or conditions not understood should be
reported to the dealer, distributor, service agent or the

Introduction
Introduction
Harnessing
The “B” electronic control is composed of the
electronic control unit and the control fuse board with
wiring harness. Only an authorized person should look
inside the machine. First TURN OFF POWER, open
lid and remove any cover present. The components are
described below.
Wiring harnesses are modular – harnesses common to
various configurations are similar, while those specific
to a certain configuration can be added. There are
harnesses for inputs to the control unit, for outputs
from the control power/output unit to the machine
components, and for the main incoming power to the
control power/output unit.
Electronic Control Unit
This portion of the control contains the “intelligence” –
the micro-controller and the miscellaneous components
on the printed circuit (PC) board. The board has a
metal cover, which MUST be in place at all times
during machine operation. Operation of the machine
without this cover installed will void the warranty.
The control unit monitors and responds to input, gives
information about the status of the washer and
monitors and responds to inputs from the user
interface (keypad). The control provides signals to the
control output unit, which in turn operates the
components that control the machine functions. This is
located behind the machine control panel.
Communications
The control will accept communications with a Card
Reader in order to perform vending transactions when
a card is inserted to pay for cycles. The Card Reader
can also allow the owner to program and collect audit
information.
For detailed information on the Card Reader
Communications, refer to the third party Card Reader
manufacturer.
Control Output Fuse Board
This portion of the control contains the power supply
for the control unit, and also the switching devices
which power the components in the machine, all of
which are on the output PC board. The switching
devices are controlled by the control unit, and are solid
state.

Care of Stainless Steel
●
Remove dirt and grease with detergent and water.
Thoroughly rinse and dry after washing.
●
●
●
Avoid contact with dissimilar metals to prevent
galvanic corrosion when salty or acidic solutions
are present.
Remove discoloration or heat tint from
overheating by scouring with a powder or by
employing special chemical solutions.
●
Do not allow salty or acidic solutions to
evaporate and dry on stainless steel. Wipe clean
of any residues.
Do not leave sanitizers or sterilizing solutions on
stainless steel equipment for prolonged periods
of time.
●
When an external chemical supply is used, ensure
no siphoning of chemicals occurs when the
washer-extractor is not in use. Highly
concentrated chemicals can cause severe damage
to stainless steel and other components with the
machine. Damage of this kind is not covered by
the manufacturer’s warranty. Locate the pump
below the washer-extractor’s injection point to
prevent siphoning of chemicals into the machine.
●
Rub in the direction of the polish lines or “grain”
of the stainless steel to avoid scratch marks when
using abrasive cleaners. Use stainless steel wool
or soft non-metal bristle brushes. Do not use
ordinary steel wool or steel brushes.
●
If the stainless steel appears to be rusting, the
source of the rust may actually be an iron or steel
part not made of stainless steel, such as a nail or
screw. Tip: Paint all carbon steel parts with a
heavy protective coating. Stainless steel fasteners
should be used whenever possible.
