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 cylinder is supported with two sealed
bearings mounted in a machined cast iron
trunnion bolted to a heavy gamma frame.
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 rinse 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 operator can select from among 4 cycles,
all of which are preprogrammed at the factory.
2–2
The polypropylene supply dispenser is
located under a flexible cover on the left side
of the machine, viewed from the front. The
compartments are numbered 1–3, starting from
the left side of the machine. A nozzle flushes
dry supplies from the compartment with water
at the appropriate time in the cycle.

Electronic Control

The Electronic Control is a programmable
computer capable of running 4 cycles at 3
different cycle temperatures. A detailed
description of these cycles is included near the
end of this manual. The Electronic Control
comes paired with either a coin meter or the
CardMate Plus™ smart card vending system.
