Safety
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
l 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.
l 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.
l 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.
l Radio Frequency Emissions .A filter is
available for machines in installations where
floor space is shared with equipment sensitive
to radio frequency emissions.
l Elevation .If the machine is to be operated at
elevations of over 3,280 feet (1,000 meters)
above sea level, pay special attention to water
levels and electronic settings (particularly
temperature) or desired results may not be
achieved.
l Chemicals . Keep stainless steel surfaces free of
chemical residues.
l 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.
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.

Safe Operating Environment
(Continued)
Machine Location
l 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.
l 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
l 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.
l 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.
l 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). Large capacity
machines could experience door seal failure if
compressed air service is interrupted.
l 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.
l 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.
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.
CAUTION
SW019

F232072 9
Safety
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.
AC Inverter Drive
Machines equipped with the AC inverter drive
require special attention with regard to the
operating environment.
l 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.
l 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.
l 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 230V for 200V installations
or above 440V for 400V installations, a
buckboost transformer is recommended. If
voltage is above 240 or 480, a buckboost
transformer is required.
l 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.
l Never wash petroleum-soaked rags in the
machine. This could result in an explosion.
l Never wash machine parts or automotive parts
in the machine. This could result in serious
damage to the basket.
l 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.
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.

Operation
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 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.
An electrically operated drain valve is 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.
The machine uses an AC inverter drive control
which provides six 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 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. As a fail-safe measure,
an overtravel limit switch is installed between the
frame and the sump, stopping the AC drive when
tripped.
The operator can select from among 30 cycles, 16
of which are preprogrammed at the factory. On
export models, 10 cycles are preprogrammed at the
factory. A special permanent test cycle can be
selected to verify proper operation of the machine.
Electronic sensing of load balancing is utilized to
attempt to optimize load balance prior to extract.
The machine is equipped with five hose barbs on
the rear of the machine to facilitate connection to an
external chemical supply system. A terminal strip in
the input power junction box provides control
signals for an external chemical supply system.
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
under V-Computer Standard OPL Cycles and
V-Computer Export OPL Cycles.
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.

Operation
14 F232072
Theory of Operation (Continued)
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.
Keypad
Operation of the V-computer control is performed
with a 4-key touch keypad and LED display located
on the front of the machine. See Figure 3 for
domestic and international versions of the keypad.
The following table describes the function of the
individual keys when the machine is in RUN mode.

Operation
Conditions Monitored by the Computer
l 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.
l Power – If power is interrupted long enough for
the computer to go off, after the power is
restored, the display briefly flashes “Hold” to
indicate the interruption. The door unlock will
be disabled to keep the door from being opened
while the basket is still turning.
l Balance – The computer monitors the balance
signal provided by the AC drive during drain
steps. It will attempt to distribute the load seven
(7) times. The dot at the top of the leftmost
display digit will light following the final
unsuccessful attempt.
l 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.
l 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.
l 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.
The following table, entitled “Display Indications,”
lists the various displays and what they mean. The
operator should become familiar with these
computer displays.

Operation
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 that 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 on the left
side of the control panel. Press the round button on
the door handle and turn the door handle downward.
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.
Partial loads are a waste of energy, water, and
chemicals, and cause greater machine wear than full
loads. Partial loads also increase the possibility of a
severe out-of-balance condition.
When loading is complete, ensure that all fabric is
inside the basket. Then close and lock the door by
rotating the door handle counterclockwise until the
door handle pushbutton pops out. 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.
Be careful around the open door, particularly
when loading from a level below the door. Impact
with door edges can cause personal injury.
CAUTION
SW025
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.
WARNING

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.
Cycle Execution
A cycle can be stopped at any time by pressing the
Stop key. The machine will go to the stop routine.
When the routine is complete, the door may be
unlocked.
To display the temperature of the water while a
cycle 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 door locks, 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. See the Agitation Options table
for more information.

Operation
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. It 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. See the following table for more
information.
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 valve will open after the programmed segment
time has elapsed. If a spin step follows a drain step,
the cylinder will turn counterclockwise (forward) at
wash speed while in the drain step.
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 agitate
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 machine should drain in 30 seconds. If
the machine fails to drain, contact a qualified
service technician.
