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 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.
•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.
•Chemicals. Keep stainless steel surfaces
free of chemical residues.
•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.
SW002

Safe Operating Environment
(Continued)
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.
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.
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.

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.
Electrical controls for the machine are housed
in a separate enclosure located on the top of
the machine. Removing the screws from
the module cover, lifting the cover, and
pulling to the rear provides access to the
control module. This module contains the
S-series microcomputer, contactors, water-
level switch, and other control components.

Operation
F232087
The 2-speed machines use one 2-speed motor
to drive the cylinder via a V-belt drive in both
speeds. The 3-speed machines use one 1-speed
motor and one 2-speed motor to drive the
cylinder via a V-belt drive in both speeds. The
cylinder is supported via the shaft by two
bearings. The UW35 uses two ball bearings
held in place by a single cast iron housing that
is bolted to the A-frame. The UW60 uses two
flange-mounted, spherical roller bearings
bolted to the A-frame.
The cylinder is constructed with lifters or ribs
that lift the laundry from the bath solution
when the cylinder rotates at slow speed and
then allow the laundry to tumble back into the
bath. This mechanical action accomplishes the
washing function. The cylinder is perforated,
allowing the water to drain from within during
the wash and extract steps.
The spray rinse feature consists of a fiber-
reinforced clear hose connected to the center
of the door glass and to both a hot and cold
water inlet valve. A hemispherically-shaped
spray nozzle inside the door glass produces a
fan-action water spray which disperses rinse
water throughout the load.
The operator can select from among 30 cycles,
12 of which are preprogrammed at the factory.
A special permanent test cycle can be selected
to verify proper operation of the machine.
On the UW60, a balance switch is installed
between the faces of the A-frame to signal the
controls to slow the machine when a severely
out-of-balance load occurs during extract.
Water enters the machine through
electromechanical water valves controlled
by the microcomputer. The microcomputer
also controls the drain and door lock. In
addition, it selects the water levels according
to the programmed cycle. Vacuum breakers
are installed in the water-inlet plumbing to
prevent backflow of water.
The standard production UW35 and UW60
models use a single drain valve. (A dual drain
is available as an option.) The drain valves are
normally open, which means that they close
only when power is applied, thus allowing the
machine to drain in the event of a power
failure.
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. The doorbox
contains the door-lock microswitch, door-
closed magnetic switch, and the door-unlock
solenoid.
The UW35 shaft seal assembly includes two
lip seals integrated into the cast-iron bearing
housing. Each seal has two lips which make
contact with a stainless steel bushing mounted
to the shaft.
The UW60 shaft seal assembly includes a
brass collar held in place on the cylinder shaft
with set screws. The collar has a flange with a
ceramic ring which makes contact with a
spring-loaded phenolic face seal enclosed in a
nylon housing mounted on the rear of the shell.
The collar contains two internal O rings which
maintain contact with the cylinder shaft.
The polypropylene supply dispenser is
mounted on the right side of the washer-
extractor, viewed from the front. The dispenser
has 5 supply compartments, numbered 1–5,
starting from the rear of the machine. The
compartments hold plastic supply cups that are
used for either liquid or dry supplies. A nozzle

Operation
14 F232087
flushes supplies from the cups with water
when called for in the cycle program.Theory
Of Operation (Continued)
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.
S-Computer
The S-computer control is a programmable
solid-state control capable of storing and
running up to 30 cycles. A detailed description
of the 12 preprogrammed cycles can be found
in the Programming section of this manual
under S-Computer Standard 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.
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 S-computer control is
performed with a 4-key touch keypad and LED
display located on the front of the machine.
See Figure 2–2. The following table describes
the function of the individual keys when the
machine is in RUN mode.

16 F232087
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”for thirty seconds.
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
Use left hand to press and hold the door unlock
button located on the lower right front of the
control panel. Use right hand to turn door
handle clockwise and swing the door left to
open. See Figure 2–3.
Figure 2–4
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. The machine should not start or run
unless the door is both closed and locked.
Be careful around the open door,
particularly when loading from a level
below the door. Impact with door edges
can cause personal injury.
SW025
CAUTION
Never operate the machine with a bypassed
or disconnected out-of-balance switch.
Operating the machine with severe
out-of-balance loads could result in personal
injury and serious equipment damage.
SW010

Supply Dispenser
Supplies are placed in the supply dispenser
compartment cups prior to the start of
each cycle.
Liquid supplies can be injected directly into
the supply dispenser by an external chemical
supply system.
Note: Supply dispenser compartment cups
must not be removed when an external
chemical injection supply system is attached to
the washer-extractor.
Note: External supply signal 5 is energized
and supply dispenser compartment 5 flushes
whenever a Supply 4 or Supply 7 (Supply 3
and Supply 4 combined) is called for in a
program segment.
Cycle Selection
Note: Press keys at their centers just hard

CAUTION

Operation
18 F232087
Cycle Execution (Continued)
Note: The display pauses the cycle time
countdown during the fill, heat, and
drain steps.
Each of the 30 cycles consists of 8 segments:
Prewash, Wash, and Fills 1–6. 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 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.
Spray Rinse
Fill segments 1–5 can be designated as spray
rinse segments on standard models. During a
spray rinse segment, the basket rotates at
extract speed while the spray rinse nozzle
mounted in the door sprays a fan-shaped
stream of cold water into the basket.
Wash
Standard Wash
As soon as water level is reached (and any
programmed temperature is reached), the
displayed time begins counting down at one-
second intervals.
All but three cycles use the standard wash
agitation. This agitation repeats for the first
programmed time duration in the prewash,
wash, and fill segments.
The standard wash agitation sequence:
•12 seconds counterclockwise at
wash speed
•A 3-second pause
•12 seconds clockwise at wash speed
•A 3-second pause
Note: While a cycle is in progress, pressing
and holding the Start key will cause the
current cycle number to be displayed. Pressing
and holding the Up key while a cycle is
running will display the temperature inside
the sump.
