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 valve closes when power is applied
and opens when power is removed, 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.
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 four 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 inverter drive uses special 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.
The operator can select from among 10
preprogrammed
cycles and program up to six for a total of 16
cycles available. A special permanent test
cycle can be selected to verify proper
operation of the machine.
V-Computer
The V-computer control is a programmable
solid-state control capable of storing and
running up to 16 cycles. A detailed
description of these cycles can be found in
the Programming section of this manual.
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.
Never turn the power off while the
Note:
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.
