Machine Overview

The UWPV features spray rinse, temperature-
controlled fill, thermal cool-down, and
variable frequency drive with seven
programmable speeds. Water reuse control
capability is standard with the UWPV.
The design of the washer-extractor emphasizes
performance reliability and long service life.
The cylinder, shell, and main body panels are
fabricated of stainless steel. The washer-
extractor is mounted on a welded base frame
which supports the bearings, cylinder, and
shell.
Electrical controls for the washer-extractor are
housed in a separate enclosure located on the
top of the machine. Removing the screws from

Installation

the module cover, lifting the cover, and
pulling to the rear provides access to the
control module. This module contains the
WE-6 microcomputer, contactors, water-level
switch, and other control components.
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 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.
All UWPV washer-extractors use an AC
inverter drive control which provides seven
preset motor speeds using a single motor. The
AC drive interface board converts motor logic
from the WE-6 computer to the correct signals
for the AC inverter drive. In addition, all
logic inputs to the computer are routed through
this board.
