Safe Operating Environment
Safe operation requires an appropriate operating
environment for both the operator and the machine. If
questions regarding safety arise, contact the factory
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, or water heaters 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 meters) 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
freeofchemical residues.
NEVER insert hands or objects into
basket until it has completely stopped.
Doing so could result in serious injury.
SW012
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.

●Water Damage. Do not spray the machine with
water. Short circuiting and serious damage may
result.
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.
●Service/Maintenance Space. Provide sufficient
space to allow comfortable performance of
service procedures and routine preventive
maintenance.
This is especially important in connection with
machines equipped with an AC inverter drive.
Consult installation instructions for specific details.
Input and Output Services
●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.
●Compressed Air. For machines requiring
compressed air service, best performance will be
realized if air is provided at a pressure of
80 – 100 psi (5.4 – 6.7 bar).
●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 easy-
access cutoff switch should also be provided.
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.
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
DANGER
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
CAUTION
Ensure that a ground wire from a proven
earth ground is connected to the ground
lug near the input power block on this

AC Inverter Drive
Machines equipped with the AC inverter drive require
special attention with regard to the operating
environment.
●An especially dusty or linty environment will
require more frequent cleaning of the AC inverter
drive cooling fan filter and of the AC inverter
drive itself.
●Power line fluctuations from sources such as
uninterruptible power supplies (UPS) can
adversely affect machines equipped with the AC
inverter drive. Proper suppression devices should
be utilized on the incoming power to the machine
to avoid problems.
●A clean power supply free from voltage spikes
and surges is absolutely essential for machines
equipped with the AC inverter drive. Nonlinear
inconsistencies (peaks and valleys) in the power
supply can cause the AC inverter drive to
generate nuisance errors.
If voltage is above 240 Volt for 200 Volt
installations or above 480 Volt for 400 Volt
installations, a buckboost transformer is required.
●Sufficient space to perform service procedures
and routine preventive maintenance is especially
important for machines equipped with the AC
inverter drive.
Misuse
Never use this machine for any purpose other than
washing fabric with water.
●Never wash petroleum-soaked rags in the
machine. This could result in an explosion.
●Never wash machine parts or automotive parts in
the machine. This could result in serious damage
to the basket.
●Never allow children to play on or around this
machine. Death or serious injury can result if
children become trapped in the machine. Do not
leave children unattended while the machine door
is open. These cautions apply to animals as well.

Theory of Operation
The design of the machine emphasizes performance
reliability and long service life. The cylinder, shell,
and main body panels are fabricated of stainless steel.
The cylinder is driven by a V-drive system supported
via the shaft by two flange-mounted spherical roller
bearings bolted to the A-frame.
The machine uses one motor to drive the cylinder via a
V-belt drive in all speeds.
A door-lock system prevents opening of the stainless
steel door when water is in the machine. It also
prevents operation of the machine when the door is
open.
Electrically operated drain valves are used to retain the
water and wash solution in the machine during the
wash and fill steps. The drain valve closes when power
is applied and opens when power is removed, allowing
the machine to drain in the event of a power failure.
The cylinder is designed with lifters or ribs that lift the
garments from the wash solution when the cylinder
rotates at slow speed and allow the garments to tumble
back into the solution. The cylinder is perforated,
allowing the water to pass through and drain from
within during the wash process and extract.
Electrical controls for the machine are housed in a
separate enclosure located underneath the top cover of
the machine.
There are two possible load balance systems, the “AC
Inverter Drive Balance Detection” and the “Overtravel
Balance Detection.”
The balance detection system using the overtravel
limit switch does not rely on the AC inverter drive and
does not attempt to balance the load in a drain step. As
the cylinder is spinning at the programmed speed, if
the wash load becomes unbalanced, the overtravel
limit switch is “tripped” causing the cylinder to slow
to a stop until the end of the spin step.
The balance detection system using the AC inverter
drive uses special balance detection software in
conjunction with the V-computer to prevent out-of-
balance conditions. When the AC drive detects an
unbalanced load at the end of a drain step, the
computer will make up to seven attempts to balance
the load. After the seventh try the machine spins at a
safe speed. As a fail-safe measure, an overtravel limit
switch is installed.
The machine uses an AC inverter drive control which
provides five motor speeds using a single motor. The
solid state output board converts motor logic from the
V-computer to the correct signals for the AC inverter
drive.
The operator can select from among 30 cycles. A
special permanent test cycle can be selected to verify
proper operation of the machine.
Liquid supplies can be injected directly into the cups
by a customer-supplied external chemical supply
system. Five hose strain reliefs on top of the supply
dispenser facilitate connection to an external supply
system. A terminal strip inside a compartment
attached to the left side of the control module, viewed
from the rear of the washer-extractor, provides
connection points for external supply signals.
V-Computer
The V-computer control is a programmable solid-state
control capable of storing and running up to 30 cycles.
A detailed description of these cycles can be found in
the Programming section of this manual.
If this machine’s computer has been equipped with
special preprogrammed cycles, a separate insert listing
these cycles has been included in the resealable plastic
bag which contained this manual.
NOTE: Never turn the power off while the
computer mode switch is in the Program position.
Such action will disorder portions of the
programmed data, necessitating reprogramming of
some or all of the existing cycles. Always return the
mode switch to Run position before turning the
power off.

F232123
Keypad
Operation of the V-computer control is performed with
a four-key touch keypad and LED display located on
the front of the machine. Refer to Figure 3.
Figure 3
Table 1 describes the function of the individual keys
when the machine is in Run Mode.
Table 1
Conditions Monitored by the Computer
●Door – The computer continuously monitors
the open/locked status of the door. If it detects
that the door is open during a wash cycle, it
immediately aborts the cycle and executes the
stop routine.
●Power – If power is interrupted long enough
for the computer to go off, after the power is
restored, the display flashes “Hold” briefly to
indicate the interruption. The door unlock will be
disabled to keep the door from being opened
while the basket is still turning.
●Balance – If the AC inverter balance detection
system is utilized, the computer monitors the
balance signal provided by the AC drive during
drain steps. The computer will attempt to
distribute the load seven times. The dot at the
top of the leftmost display digit will light
following the final unsuccessful attempt. If the
inverter balance detection is not utilized, this dot
will not light.
●Water level – The computer attempts to maintain
the water level programmed for the fill preceding
the agitation step. If the level falls below the
programmed level, the computer will stop the
time countdown and re-energize the fill valves
until the level is restored.
●Water level in a heat step – In order for the
computer to energize the heat output, there must
be at least a low water level in the machine. If this
minimum level is not detected, the heat output
will be turned off until the required level is
restored.
●Temperature probe problem – If the
temperature sensor fails when prompted for
degrees Fahrenheit, the computer flashes “tSFL”
in Program Mode rather than showing the
temperature. If the temperature sensor fails when
prompted for degrees Celsius, the display will
read “-17C” rather than showing the temperature.

Start-Up
Turn on the main power source (circuit breaker or cut-
off switch on the wall).
An identification code will appear for approximately
five seconds. Then the display will flash “Hold”
briefly.
The display will then read “CY” followed by a two-
digit cycle number (01 – 30) to indicate that a cycle
can be selected. This display will be shown at all times
when power is on between cycles, indicating that the
door-unlock solenoid will function if the door-unlock
button is pressed. The machine is then ready for
loading and unloading.
Opening Door
Press and hold the door-unlock button next to the door
handle and turn door handle upward.
Loading
Load the machine to full capacity whenever possible,
but do not exceed the rated dry-weight capacity of the
machine if the fabric to be washed is quite dense,
closely woven, and heavily soiled. Overloading can
result in an inferior wash. The operator may need to
experiment to determine load size based on fabric
content, soil content, and level of cleanliness required.
NOTE: Washing small loads can cause out-of-
balance conditions which shorten life of bearing,
seals, basket/shaft assembly, etc.
When loading is complete, ensure that all fabric is
inside the basket. Then close and lock the door by
rotating the door handle clockwise until the door
handle is horizontal. The machine should not start or
run unless the door is both closed and locked.
NOTE: When washing items which may
disintegrate, such as mop heads or sponges, use
laundry net bags to prevent drain blockage.
Cycle Selection
NOTE: Press keys at their centers just hard enough
to activate them.
Press the Up or Down key until the desired cycle
number is displayed. The computer will skip blank
(unprogrammed) cycles automatically. Press the Start
key to start the cycle. For a more detailed description
of the preprogrammed cycles, refer to the cycle charts
at the end of the Programming section.
If the computer detects that the door is not properly
closed when the Start key is pressed, the display will
read “door” until the door is closed and locked. Press
Start again to begin the desired cycle.
Be careful around the open door,
particularly when loading from a level
below the door. Impact with door edges
can cause personal injury.

is running, press the Up key. To display the number of
the cycle in progress, press the Start key.
NOTE: The computer does not count down the
remaining cycle time during fills, drains, cool-
down, or prior to first achieving the programmed
heat temperature when heating. The computer
resumes counting down cycle time once the
programmed fill level is reached, when the machine
has drained, and after a programmed heat
temperature is reached.
Each of the 30 cycles consists of 11 segments:
PreWash, Wash, and Fills 1 – 9. A description of the
various steps in a cycle segment follows:
Fill
After the Start key is pressed, the drain closes and the
machine begins filling to the programmed level. Each
programmed segment begins with a fill. The display
counts down the remaining cycle time in minutes and
seconds while the cycle is running.
If a supply is programmed in a step, the supply
dispenser will flush during the fill of that segment.
If the machine is connected to an external chemical
supply system, the programmed supply will begin
10 seconds into the fill. The supply will remain on
until the programmed water level is reached, or until
60 seconds have elapsed, whichever happens first.
If agitation options 1 or 2 are selected for the cycle
program, the cylinder will rotate slowly during the fill
step. If agitation options 3 or 4 are selected for the
cycle program, the cylinder will not rotate during the
fill step. Refer to Table 3 for more information.
If the computer does not receive a signal that water
level has been attained within 30 minutes, it will
alternately flash “STOP” and “FILL” and sound the
on-board beeper for ten seconds. The computer will
then initiate the stop routine.
Wash
As soon as water level is reached (and any
programmed temperature is reached), the displayed
time begins counting down at one-second intervals.
Agitation is active during this portion of the segment.
There are four different agitation actions available.
Refer to Table 3 for more information.
Table 3
If the segment contains a heat step, the machine begins
heating after the water has reached the programmed
level.
NOTE: If the water does not reach the
programmed temperature in 40 minutes, the
computer progresses to the wash step.

Drain
If the cycle program segment calls for a drain, the
drain valves will open after the programmed segment
time has elapsed. If a spin step follows a drain step, the
cylinder will turn clockwise (forward) at wash speed
for several seconds at the beginning of the drain step.
This clockwise direction mirrors the spin rotation and
is, therefore, also considered forward.
The cylinder then accelerates to distribution speed to
help ensure that the load is evenly distributed. The
drains open several seconds later.
NOTE: The machine should drain in 30 seconds. If
the machine fails to drain, contact a qualified
service technician.
If the cycle program segment does not call for a drain,
the computer moves to the next segment of the cycle
program. If the segment is at the end of a cycle
program, the computer goes into the stop routine.
If the cycle program segment does not call for a spin,
the cylinder will continue to turn at wash speed
throughout the drain step. When the drain has
completed, the computer moves to the next segment of
the cycle program. If the segment is at the end of a
cycle program, the computer goes into the stop
routine.
NOTE: The drain step in the final segment (Fill 9)
cannot be skipped.
Spin
After the drain sequence ends, the speed of the
cylinder increases to the extract speed if the
programmed spin time is not zero. The displayed time
resumes counting down at one-second intervals.
After the programmed spin time has elapsed, the
computer moves on to the fill step in the next segment
of the cycle. If the spin is at the end of the cycle, the
computer begins the stop routine.
Stop Routine
When the computer concludes the wash cycle or when
the Stop key is pressed while a cycle is in progress, the
computer goes into the stop routine.
The stop routine sequence:
●All inputs are turned off
●A brief pause, allowing the cylinder to coast
down if in extract
●Brief rotation counterclockwise at wash speed
●A brief pause
●Brief rotation clockwise at wash speed
●A brief pause
●The display shows “donE”
●The door interlock is energized, allowing the
door to be opened
If the stop routine seems excessively long, check for
“FULL” or “rotA” messages. If this occurs, contact a
qualified service technician.
Once “donE” is displayed, open the door by pressing
and holding the door-unlock button as described
earlier. Once the door is opened, the computer display
will show the most recent cycle number.
The machine is now ready to begin another wash
cycle.
NOTE: A test cycle is provided as a means of
verifying proper machine operation. Refer to the
Programming section for instructions on running
the test cycle.
NEVER insert hands or objects into
basket until it has completely stopped.
Doing so could result in serious injury.

Balance Detection
Each machine is equipped with either an AC inverter
drive balance detection system or an overtravel limit
switch balance detection system. To determine which
system the machine is equipped with, consult the
wiring diagram sent with the machine.
Overtravel Limit Switch Balance Detection
This system uses the overtravel limit switch only; the
AC drive balance detection system is not utilized. As
the cylinder is spinning at the programmed speed, if
the wash load becomes unbalanced, the overtravel
limit switch is “tripped” causing the cylinder to slow
to a stop until the end of the spin step.
AC Inverter Drive Balance Detection
Load balance is monitored by the AC inverter drive
during any drain step that immediately precedes a spin
step.
If a spin step follows a drain step, the cylinder
accelerates to distribution speed seven seconds into the
drain step.
The computer begins monitoring the balance signal
from the AC inverter drive eight seconds after the
water level drops below low level. If the balance signal
indicates that the wash load is evenly distributed, the
computer will start the spin step.
If the balance signal indicates that the wash load is
unbalanced, the computer will slow the cylinder down
to wash speed for seven seconds in an attempt to
redistribute the load. The computer will make as many
as seven attempts if needed.
If on the seventh attempt the load is not balanced, the
machine will light the out-of-balance LED indicator
located in the upper left corner of the display (to the
left of the first digit) until the drain step is complete.
The machine will then continue the spin speed at a
safe level.
If this occurs in the final segment, the machine will
skip the spin step and initiate the stop routine. The out-
of-balance LED indicator will remain lit until the door
is opened.
As a fail-safe measure, an overtravel limit switch will
“trip” during a spin if the wash load becomes severely
unbalanced, slowing the cylinder to a stop until the end
of the spin step.
Motor Thermal Overload Indicator
If the machine is equipped with a small indicator lamp
on the side of the control module, it will light to
indicate that a thermal overload switch in the motor
has shut off the AC power to the computer board,
thereby preventing damage to the motor caused by
overheating and/or an overload condition. This feature
protects and extends the life of the motor.
The thermal overload switch will automatically reset
itself after the excessive heat condition has subsided.
Before attempting to restart the washer-extractor,
determine the reason for the overload. The following is
a partial list of possible problems:
●Washer-extractor not fully drained before spin
●Out-of-balance condition
●Low voltage
●Loss of one phase on a three-phase motor
●Bad bearings
●Air circulation blocked to motor
Contact a service technician to correct serious
problems. Failure to take corrective action will
ultimately result in damage to the motor and/or the
inverter drive.
