6 F232073

Safe Operating Environment

Safe operation requires an appropriate operating environment for both the operator and the machine. If questions regarding safety arise, contact the factory immediately.

Environmental Conditions

Ambient Temperature. Water in the machine

will freeze at temperatures of 32° F (0° C) 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.

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

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.

'$1*(5

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.

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.

SW002

F232073 7

Safety

Safe Operating Environment

(Continued)

Machine Location

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.

&$87,21

Replace all panels that are removed to perform service and maintenance procedures. Do not operate the machine with missing guards or with broken or missing parts. Do not bypass any safety devices.

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.

SW019

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.

:$51,1*

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.

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.

Safety

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 on 50-pound capacity machines and smaller is supported with two sealed bearings mounted in a machined cast iron trunnion bolted to a heavy gamma frame.

On 80-pound capacity machines, the cylinder and shaft assembly is supported by two flange roller bearing assemblies. The bearing housings are bolted to the frame.

The 2-speed machines use one dual-speed motor to drive the cylinder via a V-belt drive in wash speed and extract speed.

The 3-speed 18-pound capacity models use one triple-speed motor, while all other 3-speed models use one single-speed and one dual-speed motor to drive the cylinder at wash speed, medium extract speed, and high extract speed.

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 30 cycles, 12 of which are preprogrammed at the factory. A special permanent test cycle can be selected to verify proper operation of the machine.

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.

Liquid supplies can be injected directly into the dispenser compartments by a customer-supplied external chemical supply system. Four hose barbs on the rear of the machine facilitate connection to an external chemical supply system. A terminal strip in the input power junction box provides control signals.

S-Computer

The S-computer control is a programmable solidstate control capable of storing and running up to 30 cycles. A detailed description of these cycles can be found in the Programming section of this manual under S-computer Standard OPL Cycles.

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.

Note: Never turn the power off while the 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.

Start-Up

Turn on the main power source (circuit breaker or cut-off switch on the wall).

An identification code will appear for approximately five seconds. Then the display will flash “hold” for thirty seconds.

The display will then read “CY” followed by a twodigit cycle number (01 – 30) to indicate that a cycle can be selected. This display will be shown at all times that power is on between cycles, indicating that the door-unlock solenoid will function if the door-unlock button is pressed. The machine is then ready for loading and unloading.

Opening Door

:$51,1*

Never operate the machine with a bypassed or disconnected out-of-balance switch. Operating the machine with severe out-of-balance loads could result in personal injury and serious equipment damage.

SW010

When loading is complete, ensure that all fabric is inside the basket. Then close and lock the door by rotating the door handle counterclockwise until the door handle pushbutton pops out. The machine should not start or run unless the door is both closed and locked.

Press and hold the door-unlock button on the left side of the control panel. Press the round button on the door handle and turn the door handle downward.

&$87,21

Be careful around the open door, particularly when loading from a level below the door. Impact with door edges can cause personal injury.

Load the machine to full capacity whenever possible, but do not exceed the rated dry-weight capacity of the machine if the fabric to be washed is quite dense, closely woven, and heavily soiled. Overloading can result in an inferior wash. The operator may need to experiment to determine load size based on fabric content, soil content, and level of cleanliness required.

SW025

&$87,21

Check the door safety interlock daily before the machine is placed in operation.

Note: When washing items which may disintegrate,

such as mop heads or sponges, use laundry net bags to prevent drain blockage.

SW024

Partial loads are a waste of energy, water, and chemicals, and cause greater machine wear than full loads. Partial loads also increase the possibility of a severe out-of-balance condition.

16 F232073

Safety

Supply Dispenser

Both liquid and powder supplies may be added by raising the flexible cover of the dispenser. Liquid supplies may also be injected directly into the supply dispenser by an external chemical supply system.

Note: When a liquid supply is manually added to

the machine through supply compartments 1 or 2, that liquid is immediately dispensed to the laundry load. Therefore, when adding supplies such as liquid detergent and bleach to the machine, coordinate the addition of the supply with the appropriate cycle segment. Add softener to compartment 3 at the beginning of the cycle. The machine automatically dispenses softener at the appropriate time.

Cycle Selection

Note: Press keys at their centers just hard enough to

activate them.

Press the Up or Down key until the desired cycle number is displayed. Press the Start key to start the cycle. For a more detailed description of the preprogrammed cycles, see the cycle charts at the end of the Programming section.

Cycle Execution

A cycle can be stopped at any time by pressing the Stop key. The machine will go to the stop routine. When the routine is complete, the door may be unlocked.

To display the temperature of the water while a cycle is running, press the Up key. To display the number of the cycle in progress, press the Start key.

Note: The display pauses the cycle time countdown

during the fill, heat, and drain steps.

Each of the 30 cycles consists of 8 segments: Prewash, Wash, and Fills 1 – 6. A description of the various steps in a cycle segment follows:

Fill

After the Start key is pressed, the door locks, the drain closes, and the machine begins filling to the programmed level; each programmed segment begins with a fill. The display counts down the remaining cycle time in minutes and seconds while the cycle is running.

If a supply is programmed in a step, the supply dispenser will flush during the fill of that segment.

If the computer detects that the door is not properly closed when the Start key is pressed, the display will read “door” until the door is closed and locked. Press the Start key again to begin the desired cycle.

F232073 17

Safety

Cycle Execution (Continued)

If the machine is connected to an external chemical supply system, the programmed supply will begin 10 seconds into the fill. The supply will remain on until the programmed water level is reached, or until 60 seconds have elapsed, whichever happens first.

If the computer does not receive a signal that water level has been attained within 30 minutes, it will alternately flash “STOP” and “FILL” and sound the on-board beeper for ten seconds; it will then initiate the stop routine.

Wash

Standard Wash

As soon as water level is reached (and any programmed temperature is reached), the displayed time begins counting down at one-second intervals.

All but three cycles use the standard wash agitation. This agitation repeats for the first programmed time duration in the prewash, wash, and fill segments.

Gentle Wash

Cycles 8, 16, and 24 use a gentle wash agitation in place of the standard wash agitation. This agitation repeats for the programmed segment time duration in the prewash, wash, and fill segments.

The gentle wash agitation sequence:

3 seconds counterclockwise at wash speed

A 12-second pause

3 seconds clockwise at wash speed

A 12-second pause

Heat

If the segment contains a heat step, the machine begins heating after the water has reached the programmed level.

Note: If the water does not reach the programmed

temperature in 30 minutes, the computer progresses to the wash step.

The standard wash agitation sequence:

12 seconds counterclockwise at wash speed

A 3-second pause

12 seconds clockwise at wash speed

A 3-second pause

Note: While a cycle is in progress, pressing and

holding the Start key will cause the current cycle number to be displayed. Pressing and holding the Up key while a cycle is running will display the temperature inside the sump.

18 F232073

Safety

Drain

At the conclusion of a spin, the drain valve opens, and the cylinder turns counterclockwise (forward) at wash speed. This counterclockwise direction mirrors the spin rotation direction and is, therefore, considered forward.

Note: The machine should drain in 30 seconds. If

the machine fails to drain, contact a qualified service technician.

When the water level falls below the low level, there is a 15-second delay, during which the computer continues to monitor water level. If a water level input is sensed, the computer waits until both high and low level inputs indicate the machine is empty. Assuming the computer detects no water level during the 15-second period, the drain sequence concludes.

Stop Routine

When the programmed duration for the machine’s final spin expires, the computer begins the stop routine.

The stop routine sequence:

All inputs are turned off.

A 40-second coast-down (if stop routine is preceded by a spin)

12 seconds counterclockwise at wash speed (if stop routine is not preceded by a spin)

A 3-second pause (if stop routine is not preceded by a spin)

12 seconds clockwise at wash speed

A 5-second pause

The display shows “donE.”

The door interlock is energized, allowing the door to be opened

Spin

After the drain sequence ends, the speed of the cylinder increases to the extract speed if the programmed spin time is not zero. The displayed time resumes counting down at one-second intervals.

After the programmed spin time has elapsed, the computer moves on to the fill step in the next segment of the cycle. If the spin is at the end of the cycle, the computer begins the stop routine.

:$51,1*

NEVER insert hands or objects into basket until it has completely stopped. Doing so could result in serious injury.

Once “donE” is displayed, open the door by pressing and holding the door unlock button as described earlier. Once the door is opened, the computer display will show the most recent cycle number.

The machine is now ready to begin another wash cycle.
