• 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

Do not place volatile or flammable fluids in any machine. Do not clean the machine with volatile or flammable fluids such as acetone, lacquer thinners, enamel reducers, carbon tetrachloride, gasoline, benzene, naptha, etc. Doing so could result in serious personal injury and/or damage to the machine.

SW002

• Water Damage. Do not spray the machine with water. Short circuiting and serious damage may result. Repair immediately all 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.
