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
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.

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.
WARNING
Never operate the machine with a
bypassed or disconnected balance
system. Operating the machine with
severe out-of-balance loads could result
in personal injury and serious equipment
damage.
Safe operation requires an appropriate operating
environment for both the operator and the machine. If
questions regarding safety arise, contact the
manufacturer immediately.
Environmental Conditions
• Ambient Temperature. Water in the machine will
freeze at temperatures of 32°F (0°C) or below.
Temperatures above 120°F (50°C) will result in
more frequent motor overheating and, in some
cases, malfunction or premature damage to solid
state devices that are used in some models.
Special cooling devices may be necessary.
Water pressure switches are affected by increases
and decreases in temperature. Every 25°F (10°C)
change in temperature will have a 1% effect on
the water level.
• Humidity. Relative humidity above 90% may
cause the machine’s electronics or motors to
malfunction or may trip the ground fault
interrupter. Corrosion problems may occur on
some metal components in the machine.
If the relative humidity is below 30%, belts and
rubber hoses may eventually develop dry rot.
This condition can result in hose leaks, which
may cause safety hazards external to the machine
in conjunction with adjacent electrical
equipment.
• Ventilation. The need for make-up air openings
for such laundry room accessories as dryers,
ironers, water heaters, etc., must be evaluated
periodically. Louvers, screens, or other
separating devices may reduce the available air
opening significantly.
• Radio Frequency Emissions. A filter is available
for machines in installations where floor space is
shared with equipment sensitive to radio
frequency emissions.
• Elevation. If the machine is to be operated at
elevations of over 3280 feet (1000 m) above sea
level, pay special attention to water levels and
electronic settings (particularly temperature) or
desired results may not be achieved.
• Chemicals. Keep stainless steel surfaces free of
chemical residues.

Safety Information
Input and Output Services
DANGER
Do not place volatile or flammable fluids
in any machine. Do not clean the machine
with volatile or flammable fluids such as
acetone, lacquer thinners, enamel
reducers, carbon tetrachloride, gasoline,
benzene, naptha, etc. Doing so could
result in serious personal injury and/or
damage to the machine.
SW002
• Water Damage. Do not spray the machine with
water. Short circuiting and serious damage may
result. Repair immediately all seepage due to
worn or damaged gaskets, etc.
Machine Location
• Foundation. The concrete floor must be of
sufficient strength and thickness to handle the
floor loads generated by the high extract speeds
of the machine. Refer to Installation manual.
• Service/Maintenance Space. Provide sufficient
space to allow comfortable performance of
service procedures and routine preventive
maintenance.
Consult installation instructions for specific details.
CAUTION
Replace all panels that are removed to
perform service and maintenance
procedures. Do not operate the machine
with missing guards or with broken or
missing parts. Do not bypass any safety
devices.
SW019
• Water Pressure. Best performance will be
realized if water is provided at a pressure of 30 –
85 psi (2.0 – 5.7 bar). Although the machine will
function properly at lower pressure, increased fill
times will occur. Water pressure higher than
100 psi (6.7 bar) may result in damage to
machine plumbing. Component failure(s) and
personal injury could result.
• Steam Heat (Optional) Pressure. Best
performance will be realized if steam is provided
at a pressure of 30 – 80 psi (2.0 – 5.4 bar). Steam
pressure higher than 125 psi (8.5 bar) may result
in damage to steam components and may cause
personal injury.
For machines equipped with optional steam heat,
install piping in accordance with approved
commercial steam practices. Failure to install the
supplied steam filter may void the warranty.
• Drainage System. Provide drain lines or troughs
large enough to accommodate the total number of
gallons that could be dumped if all machines on
the site drained at the same time from the highest
attainable level. If troughs are used, they should
be covered to support light foot traffic.
• Power. For personal safety and for proper
operation, the machine must be grounded in
accordance with state and local codes. The
ground connection must be to a proven earth
ground, not to conduit or water pipes. Do not use
fuses in place of the circuit breaker. An easyaccess cutoff switch should also be provided.
WARNING
Ensure that a ground wire from a proven
earth ground is connected to the ground
lug near the input power block on this
machine. Without proper grounding,
personal injury from electric shock could
occur and machine malfunctions may be
evident.
SW008
Always disconnect power and water supplies before a
service technician performs any service procedure.
Where applicable, steam and/or compressed air
supplies should also be disconnected before service is
performed.

Operation
Introduction
Control Output Fuse Board
This control is composed of the electronic control unit
and the control fuse board. Beyond this, there are
wiring harnesses associated with the control. Only an
authorized person should ever look inside the machine.
Before accessing the control components, first TURN
OFF POWER, then open the lid.
This portion of the control contains the power supply
for the control unit, and also the switching devices that
power the components in the machine, all of which are
on the output PC board. The output board has a cover
for back of hand protection. It must be in place at all
times during machine operation. The switching
devices are controlled by the control unit, and are solid
state components which provide two important
benefits: 1) elimination of all the problems associated
with electromechanical switching (contact wear,
arcing and electromagnetic interference, etc.) with
subsequent increased component life, and 2) enhanced
electrical isolation of the control unit and the AC
switching components.
Electronic Control Unit
This portion of the control contains the
“intelligence” – namely, 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 machine (which the
control operates), and it monitors and responds to
inputs from the user interface. 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.
14
Harnessing
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.

Maintenance
The grease must have the following characteristics:
Deflection. Refer to Figure 11. Increase
spring tension to change belt span length. Belt
tension measurements should be taken as
close to the center of the belt span as possible.
For every inch of span length, the belt should
deflect 1/64 inch (0.40 mm). Thus, a belt with
span length of 50 inches should deflect
50/64 inch (19.84 mm). An initial (run-in)
force should be used to set the belt tension.
An operating (normal) force should be used
after the washer-extractor has been operated
for a few hours. Refer to Table 4 for those
values.
• NLGI Grade 2
• Lithium-based
• Water-insoluble
• Anti-rusting
• Anti-oxidizing
• Mechanically stable
The grease must have adequate base oil viscosity with
one of the following ratings:
• ISO VG 150 (135 – 165 cSt at 40°C or
709 – 871 SUS at 100° F)
• ISO VG 220 (198 – 242 cSt at 40°C or
1047 – 1283 SUS at 100°F)
• An SAE 40 rating is also acceptable as long as
the cSt or SUS values are within the specified
ranges.
Pump the grease gun slowly, permitting only 2 strokes.

Maintenance
Care of Stainless Steel
Maintain the natural beauty of stainless steel and
prolong its service life by following these tips:
• Ordinary deposits of dirt and grease can be
removed with detergent and water. The metal
should be thoroughly rinsed and dried after
washing. Periodic cleaning will help to maintain
the bright surface appearance and prevent
corrosion.
• Contact with dissimilar metals should be avoided
whenever possible. This will help prevent
galvanic corrosion when salty or acidic solutions
are present.
• Salty or acidic solutions should not be allowed to
evaporate and dry on stainless steel. They may
cause corrosion. Ensure that the stainless steel is
wiped clean of acidic solution residues.
• Deposits that adhere to the stainless steel should
be removed, especially from crevices and
corners. When using abrasive cleaners, always
rub in the direction of the polish lines or “grain”
of the stainless steel to avoid scratch marks.
Never use ordinary steel wool or steel brushes on
the stainless steel. Use stainless steel wool or soft
non-metal bristle brushes.
26
• 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. One remedy is to paint all carbon steel
parts with a heavy protective coating. Stainless
steel fasteners should be used whenever possible.
• Discolorations or heat tint from overheating may
be removed by scouring with a powder or by
employing special chemical solutions.
• Sanitizers or sterilizing solutions should not be
left in stainless steel equipment for prolonged
periods of time. They often contain chlorine,
which may cause corrosion. The stainless steel
should be cleaned and rinsed thoroughly of any
solution containing chlorine.
• When an external chemical supply system is
used, make certain that 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 within the washer-extractor. Damage
of this kind is not covered by the manufacturer’s
warranty. Locate the pump below the washerextractor’s injection point to prevent siphoning of
chemicals into the washer-extractor. Refer to the
Installation manual.
