Safety Information
Always contact your dealer, distributor, service agent or the manufacturer about any problems or conditions you do
not understand.
Important Safety Instructions
1. Read all instructions before using the washer.
2. Refer to the GROUNDING INSTRUCTIONS in
the INSTALLATION manual (supplied with your
washer-extractor) for the proper grounding of the
washer-extractor.
3. Do not wash textiles that have been previously
cleaned in, washed in, soaked in or spotted with
gasoline, kerosene, waxes, cooking oils, dry-
cleaning solvents or other flammable or explosive
substances. They give off vapors that could ignite
or explode.
4. Do not add gasoline, dry-cleaning solvents or
other flammable or explosive substances to the
wash water. These substances give off vapors that
could ignite or explode.
5. Under certain conditions, hydrogen gas may be
produced in a hot water system that has not been
used for two weeks or more. HYDROGEN GAS
IS EXPLOSIVE. If the hot water system has not
been used for such a period, before using a
washer-extractor, turn on all hot water faucets and
let the water flow from each for several minutes.
This will release any accumulated hydrogen gas.
The gas is flammable. Do not smoke or use an

Theory of Operation
Section 3
Theory of Operation
Starting the Machine
The door lock will not allow a cycle to be started until
the door has been closed.
Fill
The operator selects a cycle and starts the machine.
Water enters the machine through water valves that are
controlled by the microcomputer. As water fills the
basket, a column of air is trapped in a pressure bulb
and hose. The air pressure continues to increase as the
basket fills with water. When the desired water level is
reached, the water level switch triggers the
microcomputer and the water valves turn off.
A vacuum breaker installed in the inlet plumbing
prevents the backflow of water.
Supply
The operator can either connect external liquid
supplies to the machine or fill the supply dispenser
with liquid or dry supplies. The supply dispenser's
nozzles flush the compartments with water at the
appropriate times throughout a cycle.
Wash
The basket includes ribs that lift the laundry from the
wash water. The laundry then tumbles back into the
bath.
In 2-speed and variable-speed models, 1 dual-speed
motor drives the basket's shaft with a V-belt. In 3-
speed models, 2 motors drive the basket's cylinder
with a V-belt.
18-60 pound capacity models use 2 bearings that are
held in place by a single cast-iron trunnion that is
bolted to the frame. 80 and 125-pound capacity
models use 2 flange-type bearing that are bolted to the
frame.
Drain
Cabinet Hardmount washer-extractors use a normally
open gravity-type drain system. No pump is used.
When the drain valve opens, the perforated basket
allows water to drain from it.
In the event of a power failure, the drain valve will
open automatically and the machine will drain.
Extract
A final high-speed extract step removes water from the
load, which maximizes drying efficiency.
The door lock system will not allow the door to be
opened until the cycle has finished.

Troubleshooting
To reduce the risk of electrical shock, fire, explosion, serious injury or death:
• Disconnect electrical power to the washer-extractor before servicing it.
• Close the gas shut-off valve to the washer-extractor (when applicable) before servicing it.
• Never start the washer-extractor with any guards/panels removed.
• Whenever ground wires are removed during servicing, these ground wires must be
reconnected to ensure that the washer-extractor is properly grounded. W461R1
