Safety Information
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.
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.
Important Safety Instructions
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, dry-cleaning 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.
DANGER indicates the presence of a
hazard that will cause severe personal
injury, death, or substantial property
damage if the danger is ignored.
DANGER
WARNING indicates the presence of a
hazard that can cause severe personal
injury, death, or substantial property
damage if the warning is ignored.
WARNING
CAUTION indicates the presence of a
hazard that will or can cause minor
personal injury or property damage if the
caution is ignored.

traces of any flammable substances such as
vegetable oil, cooking oil, machine oil,
flammable chemicals, thinner, 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.
17. Do not use fabric softeners or products to
eliminate static unless recommended by the
manufacturer of the fabric softener or product.
18. 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.
19. Replace worn power cords and/or loose plugs.
20. 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.
21. 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.
22. 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).
23. Always follow the fabric care instructions
supplied by the textile manufacturer.
24. Never operate the washer with any guards and/or
panels removed.
25. DO NOT operate the washer with missing or
broken parts.
26. DO NOT bypass any safety devices.

Start-Up
Turn on the main power source (breaker panel or cut-
off switch on the wall). The front panel display should
light up and show “WA I T 0 0 ”for 30 seconds followed
by “NEXT 00”which means Select Cycle. This
display will be on at all times that power is on
indicating the machine is ready for loading and
unloading.
NOTE: Throughout this manual, when display
indications are referred to, these indications will
pertain to the first four digits of the display reading
left to right. The last two digits on the right side of
the display will indicate either the last cycle used or
the current cycle in process.
Loading
To load the washer, use left hand to press the door
unlock button located on the lower right front of the
control panel. Use right hand to turn door handle to the
right. The door can then be opened.
Load linen until the machine is full. Partial loads are a
waste of energy, water and chemicals and cause
greater machine wear than full loads. If you do not
have enough to fill the basket, wait until you do.
Partial loads, if necessary, should only occur at the end
of the day. Even then, they can usually be held until
the next day when more linen is received.
IMPORTANT: If stringy items such as mop heads
are to be washed, laundry nets should be used in
order to prevent fouling of seals and drains.
Once loading is complete (you cannot overload the
machine as far as harm to the machine is concerned;
however, overloading can cause improper mechanical
action and an inferior quality wash), close and lock the
door making sure that all fabric is inside the basket.
The machine should not start or run if the door is not
both closed and locked.
Select Cycle
Find the cycle number (cycle numbers must be two-
digit numbers) of the desired wash cycle from the
cycle code list provided. Press (do not punch) with
your finger the numbers desired on the keypad and
note that this number is displayed instead of “NEXT”.
When keys are pressed on the keypad, a beep will be
heard. If an error is made, simply press the CLEAR
key and then press the numbers again. As numbers are
entered, they move from right to left on the display.
Display will show “CY12”if cycle 12 is pressed.
NOTE: In order to Clear or Enter data, the display
must be filled –i.e., no blank spaces.
Start Cycle
To start the cycle that has been selected, simply press
the START key. If the cycle number selected is not in
the computer memory, the display will show
“NOGO”. If this happens, select another cycle.
Otherwise, the display will now show the first step.
(Example: “HL01”.) This number indicates the step
number in the cycle as listed in the Selection List. As
the cycle proceeds, the display will show the step
being run and the cycle number selected.
If the door is not locked, the display will indicate
“DOOR”. If this occurs, be sure the door is closed and
locked and again press the START key. If the computer
starts but the machine does nothing, this indicates the
door hinge microswitch cam may need adjusting. The
door hinge microswitch interlocks all 120 volt power
to the controls with the exception of the computer
itself.
As the cycle progresses, the display will show the step
in the cycle that is being run as well as the cycle
number. In addition, as water is being turned on to fill
the machine, one or more of the four indicator lights
above the first four digits (left to right) in the display
will come on and stay on until the required water level
is reached. Indicator lights above the last two digits on
the right will indicate the water level(s) reached. When
the indicator light in the next to last digit is
illuminated, the low water level has been reached.
Likewise, when the light in the last digit to the right
illuminates, high water level has been reached. The
cycle will continue until its completion and, at this
time, the display will show “NEXT”.

Test Cycle
Cycle number 01 is a test cycle to check out all
machine functions. The program for the cycle is shown
following the copy of the Program Worksheet.
The first step is a cold fill to low level and is designed
to give not quite enough time to complete a fill and
cause the display to read “FILL”. When the START
key is pressed again, it should continue to fill and
proceed with the test cycle.
The steps in the test cycle are relatively short with the
exception of step 3, step 15, and step 17. These can be
shortened by pressing the ADVANCE key to go on to
the next step.
End of Cycle
When the cycle is completed, the display will show
“NEXT”plus the cycle number just run. To unload the
machine, press the door unlock button and again open
the door to remove contents and place them in the
dryer.
To display temperature, press the DISPLAY TEMP.
key. Display will read “---F”as long as the key is
pressed and will update display automatically.
It is possible to skip to the next step in the cycle except
a drain step. To do so, press the ADVANCE key. Drain
procedures must be allowed to complete.
LED Display
When display shows letters and/or numbers with or
without the beeper, refer to Ta b l e 1 . The computer
control in this machine is continuously on the alert for
problems both within the machine and with the total
installation. As the computer sees a problem, it
immediately flashes a letter or number or both on the
display and may activate the beeper as well. Ta b l e 1
shows the various displays and what they mean. The
operator should become familiar with these computer
displays.
NEVER insert hands or objects into
basket until it has completely stopped.
Doing so could result in serious injury.

Motor Thermal Overload Indicator
Figure 2
Located on the side of the control module is a small
indicator lamp with the above descriptive decal.
When this lamp is lit, it indicates that there is an open
thermal overload switch on the motor(s) which shuts
off the A.C. power to the computer board thereby
preventing damage to the motor(s) caused by
overheating and/or an overload condition.
This feature is provided to protect the motor and
extend the life of the motor. The thermal overload
switch will automatically reset itself after the
excessive heat condition has subsided; however, before
attempting to restart the machine, always check to find
out the reason for the overload (e.g., machine not fully
drained before spin, defective motor, continual out of
balance condition, low voltage, loss of one phase on
three phase motor, failed bearings, air circulation
blocked to motor fan). The thermal overload switch
should not open under normal operating conditions.
Failure to take corrective action when the indicator
lamp is lit will ultimately result in damage to the
motor(s).
If you have difficulty in locating the problem, do not
hesitate to call the factory.
