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.

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 v alv e c loses when
power is applied and opens when power is remov ed,
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.
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 i n
the input power junction box provides control
signals for an external chemical supply system.
V- Computer
The V-computer control is a programmable solidstate 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.
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 inv erter dri ve uses specia l 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 f ail-safe measure,
an overtravel limit switch is installed between the
frame and the sump, stopping the AC drive when
tripped.

Operation
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 ke ypad and LED display located
on the front of the machine. See Figure 3 for

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 int errupted 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
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 Indic ations,”
lists the various displays and what they mean. The
operator should become familiar with these
computer displays.
l
Water lev e l 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.

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
Partial loads are a waste of energy, water, and
chemicals, and cause greater machine wear than full
loads. Partial loads also increa se the possibi lity of a
severe out-of-balance condition.
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.
SW039
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.
CAUTION
CAUTION
Be careful around the open door, particularly
when loading from a le v el belo w t he door. Impact
with door edges can cause personal injury.
Load the machine to full capacity whenever
possible, but do not exceed the rated dry-weight
capacity of the machine if the fa bric to be washe d 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

Operation
Supply Dispenser
The 18-pound and 25-pound capacity freestanding
models are equipped with a three-compartment
polypropylene supply dispenser. The supply
dispenser is mounted at the left top of the machine
as seen from the front. Both liquid and powder
supplies may be added by raising the flexible cover
of the dispenser.
Cycle Selection
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.
Note: Press ke ys at their centers jus t hard enough to
activate them.
Press the Up or Down key until the desired cycle
number is displayed. Press the Start key to start the
cycle. For a more detailed description of the
preprogrammed cycles, see 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.
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.
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.
18 F232072
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.
Operation
Note: If the water does not reach the programmed
temperature in 40 minutes, the computer progresses
to the wash step.
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.

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 mov es to the ne xt se gment
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.
If the segment contains a heat step, the machine
begins heating after the water has reached the
programmed level.
F232072 19
Operation
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.
Test Cycle
Note: If the stop routine seems excessively long,
check for “FULL” or “rotA” messages. If this
occurs, contact a qualified service technician.
Balance Detection
Each model comes equipped with an inverter drive
balance detection system. Load balance is detected
by the inverter drive during any drain step that
immediately precedes a spin step. The V-series
computer will make up to seven attempts to balance
the load during a drain step.
A test cycle is provided as a means of verifying
proper machine operation. Before the test cycle is
run, it must be enabled. Refer to the Programming
section of this manual for instructions on enabling
and running the test cycle.
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 consists of a brief countdown and a
brief reversing sequence, after which the computer
will display “dONE.”
W ARNING
NEVER insert hands or objects into basket until it
has completely stopped. Doing so could resul t in
serious injury.
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.
SW012
The computer begins monitoring the balance signal
from the 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 se v en 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 machines 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 ignore the
programmed spin and use a safe spin speed (not to
exceed 85 G’s) for the extract step, provided
programmed spin time is not zero.
If the load cannot be properly distributed, the
computer skips the spin and moves on to the next
segment. If the segment is at the end of a cycle
program, the computer goes into the stop routine.
The out-of-balance LED indicator will remain lit
until the door is opened.
The machine is now ready to begin another wash
cycle.
20 F232072
Overtravel Limit Switch
As a fail-safe measure, an overtravel limit switch is
installed on all machine s. The limit switc h serv es to
trigger a rapid stop. This means that if the machine
balance “passes” the inverter drive balance
detection system at the drain step but the overtravel
limit switch detects an out-of-balance load
condition at the extract step, the basket will brak e to
a rapid stop.
To reset the control, push the stop button and open
the door when the display shows “donE.”

Programming
The V-computer board is inside the control module.
Near the center of the board is a small toggle
switch: this is the RUN/PROGRAM mode switch.
W ARNING
Dangerous voltages are present i n the electrical
control box(es) and at the motor terminals. Only
qualified personnel familiar with electrical test
procedures, test equipment, and safety
precautions should attempt adjustments and
troubleshooting. Dis connect power from the
machine before removing the control box cover,
and before attempting any service procedures.
SW005
The switch is normally in the down (RUN mode)
position. T o enter PR OGRAM mode, flip the switch
to the up position. The display will now show the
current temperature in the sump.
Since the keypad operates in a slightly different
fashion when in PROGRAM mode, pay careful
attention to the programming instructions provided
in this manual.
Down–The Down key is used to decrease cycle
numbers (1 through 30) and other numerical values
such as times or temperatures (when creating wash
formulas).
Start–The Start key acts as an enter key in program
mode. Use this key to enter data and move to the
next function in the cycle.
Stop–The Stop key saves all data and terminates
the programming procedure. If it is the first key
pressed in PROGRAM mode, the computer enters
SETUP mode. The Stop key can be pressed again t o
exit SETUP mode and return to PROGRAM mode.
Setup Mode
SETUP options are programmable options that are
in effect for all wash formulas. These options
include:

Degrees Displayed in Fahrenheit or Celsius
Note: Do not enable the auxiliary heat SETUP
option and disable the temperature-controlled fill
option on machines not equipped with auxiliary
heat. The machine will pause for 40 minutes during
any cycle segment where the fill water temperature
does not equal or exceed the programmed value of
the heat step.
This SETUP option affects the programming and
display of all temperatures. If “FAr” is selected, all
temperatures will display in F ahrenheit. If “CEL” is
selected, all temperatures will display in Celsius.
Acceptable ranges for programmable temperatures
are 75°F – 200°F or 25°C – 93°C.
Auxiliary Heat
Heat is a dedicated output of the V-computer, which
controls an optional heat source. If “nOHt” is
selected, the heat output will never energize during
a cycle (except briefly in the test cycle to ensure that
the output functions properly), regardless of
programmed temperature settings. If “HEAt” is
selected, the output will energize during a cycle if
the three following conditions are true:
l
A nonzero heat temperatureis programmed.
l
The computer senses that the present
temperature is below the programmed target
temperature.
l
There is at least a low water level in the
machine.
Supply 5 or Auxiliary Fill
If “SUP5” is selected, the output labeled AF on the
solid state output board can be used to control a
fifth supply signal. This SETUP option must be
selected to program a “SUP5” or a “SUP6” (supply
1 and supply 5 combined) in a cycle step.
If “AFIL” is selected, the output labeled AF can be
used to control an auxiliary fill v alve. Auxiliary f ills
can be programmed to low, medium, or high water
level. It is also possible to program an overflow
(flush) in Prewash. This SETUP option must be
selected to program an “AFIL” in a cycle step.
Temperature-Controlled Fill
If “tFIL” is selected, a temperature-controlled fill
can be programmed for any segment. This SETUP
option must be selected to program a “tFIL” in a
cycle step. If “ntFL” is selected, this feature is
disabled.
24 F232072
Automatic Cool-Down
If “CooL” is selected, the automatic cool-down
feature is enabled. If the wash solution is 140°F
(60°C) or higher when a cycle step calls for a drain,
the washing action will continue and the cold wate r
valve will begin flushing cold water into the wash
solution. Once the wash solution temperature drops
below 140°F (60°C), the drain opens and the cycle
continues as programmed. If “noCL” is selected,
this feature is disabled.

Agitation Speed
If “AgSn” is selected, the machine uses the normal
wash speed for the duration of the cycle. If “AgSL”
is selected, the machine use s the gentle was h speed.
Gentle wash speed is approximately half the speed
of the normal wash speed.
Recirculation Pump
This cycle option setting is intended to be used with
