models. Two motors drive the cylinder for the
3-speed models. 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
39 preprogrammed cycles. Cycle 01 is a test
cycle used to verify proper operation of the
machine. With the exception of Cycle 39, the
remaining cycles are complete wash cycles or
specialty cycles designed to handle various
fabrics at specific water temperatures and
levels. Cycle 39 is designed to test an external
chemical injection supply system.
Programmable custom cycles are another
feature of the UWP.
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 washer-extractor through
electromechanical water valves controlled by
the microcomputer. The microcomputer also
controls the drain and the 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 UWP uses a single
drain valve. (Dual drains are available as an
option. The dual drains open and close
together under control of the WE-6 computer.)
The drain valve is normally open, which
means that it closes 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 a cycle is in
progress. It also prevents operation of the
washer-extractor 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 polished 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-
