• Ambient Temperature. Water in the

machine will freeze at temperatures of 32°
F or below.

Temperatures above 120° F (50° C) will
result in more frequent motor overheating
and, in some cases, malfunction or
premature damage to solid state devices
that are used in some models. Special
cooling devices may be necessary.

Water pressure switches are affected by
increases and decreases in temperature.
Every 25° F (10° C) change in temperature
will have a 1% effect on the water level.

F232096

• Humidity. Relative humidity above 90%

may cause the machine’s electronics or
motors to malfunction or may trip the
ground fault interrupter. Corrosion
problems may occur on some metal
components in the machine.

If the relative humidity is below 30%, belts
and rubber hoses may eventually develop
dry rot. This condition can result in hose
leaks, which may cause safety hazards
external to the machine in conjunction
with adjacent electrical equipment.

• Ventilation. The need for make-up air

openings for such laundry room
accessories as dryers, ironers, water
heaters, etc., must be evaluated
periodically. Louvers, screens, or other
separating devices may reduce the
available air opening significantly.

Safety

DANGER

seepage due to worn or damaged
gaskets, etc.

Machine Location

• Radio Frequency Emissions. A filter is

available for machines in installations
where floor space is shared with
equipment sensitive to radio frequency
emissions.

•

Elevation. If the machine is to be operated

at elevations of over 3,280 feet (1,000
meters) above sea level, pay special
attention to water levels and electronic
settings (particularly temperature) or
desired results may not be achieved.

Chemicals. Keep stainless steel surfaces

•

free of chemical residues.

• Foundation. The concrete floor must be of
sufficient strength and thickness to handle
the floor loads generated by the high
extract speeds of the machine.

• Service/Maintenance Space. Provide
sufficient space to allow comfortable
performance of service procedures and
routine preventive maintenance.

This is especially important in connection
with machines equipped with an AC
inverter drive.

Consult installation instructions for specific
details.

Input and Output Services

Water Pressure. Best performance will be

•

realized if water is provided at a pressure
of 30–85 psi (2.0–5.7 bar). Although the
machine will function properly at lower
pressure, increased fill times will occur.
Water pressure higher than 100 psi
(6.7 bar) may result in damage to machine
plumbing. Component failure(s) and
personal injury could result.

• Steam Heat (Optional) Pressure. Best

performance will be realized if steam is
provided at a pressure of 30–80 psi
(2.0–5.4 bar). Steam pressure higher
than 125 psi (8.5 bar) may result in
damage to steam components and may
cause personal injury.

For machines equipped with optional
steam heat, install piping in accordance
with approved commercial steam
practices. Failure to install the supplied
steam filter may void the warranty.

• Drainage System. Provide drain lines or
troughs large enough to accommodate
the total number of gallons that could
be dumped if all machines on the site
drained at the same time from the highest
attainable level. If troughs are used,
they should be covered to support light
foot traffic.

• Power. For personal safety and for proper
operation, the machine must be grounded
in accordance with state and local codes.
The ground connection must be to a
proven earth ground, not to conduit or
water pipes. Do not use fuses in place of
the circuit breaker. An easy-access cutoff
switch should also be provided.

WARNING

Ensure that a ground wire from a proven
earth ground is connected to the ground lug
near the input power block on this machine.
Without proper grounding, personal injury
from electric shock could occur and machine
malfunctions may be evident.

SW008

Always disconnect power and water supplies
before a service technician performs any
service procedure. Where applicable, steam
and/or compressed air supplies should also be
disconnected before service is performed.

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 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.

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.
