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.

FA005G

Figure 2–2

Electrical controls for the machine are housed in a separate enclosure located on the top of the machine. Removing the screws from the module cover, lifting the cover, and pulling to the rear provides access to the control module. This module contains the S-series microcomputer, contactors, waterlevel switch, and other control components.

F232087

Operation

The 2-speed machines use one 2-speed motor to drive the cylinder via a V-belt drive in both speeds. The 3-speed machines use one 1-speed motor and one 2-speed motor to drive the cylinder via a V-belt drive in both speeds. The cylinder is supported via the shaft by two bearings. The UW35 uses two ball bearings held in place by a single cast iron housing that is bolted to the A-frame. The UW60 uses two flange-mounted, spherical roller bearings bolted to the A-frame.

The cylinder is constructed with lifters or ribs that lift the laundry from the bath solution when the cylinder rotates at slow speed and then allow the laundry to tumble back into the bath. This mechanical action accomplishes the washing function. The cylinder is perforated, allowing the water to drain from within during the wash and extract steps.

addition, it selects the water levels according to the programmed cycle. Vacuum breakers are installed in the water-inlet plumbing to prevent backflow of water.

The standard production UW35 and UW60 models use a single drain valve. (A dual drain is available as an option.) The drain valves are normally open, which means that they close only when power is applied, thus allowing the machine to drain in the event of a power failure.

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. The doorbox contains the door-lock microswitch, doorclosed magnetic switch, and the door-unlock solenoid.

The spray rinse feature consists of a fiberreinforced clear hose connected to the center of the door glass and to both a hot and cold water inlet valve. A hemispherically-shaped spray nozzle inside the door glass produces a fan-action water spray which disperses rinse water throughout the load.

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.

On the UW60, a balance switch is installed between the faces of the A-frame to signal the controls to slow the machine when a severely out-of-balance load occurs during extract.

Water enters the machine through electromechanical water valves controlled by the microcomputer. The microcomputer also controls the drain and door lock. In

The UW35 shaft seal assembly includes two lip seals integrated into the cast-iron bearing housing. Each seal has two lips which make contact with a stainless steel bushing mounted to the shaft.

The UW60 shaft seal assembly includes a brass collar held in place on the cylinder shaft with set screws. The collar has a flange with a ceramic ring which makes contact with a spring-loaded phenolic face seal enclosed in a nylon housing mounted on the rear of the shell. The collar contains two internal O rings which maintain contact with the cylinder shaft.

The polypropylene supply dispenser is mounted on the right side of the washerextractor, viewed from the front. The dispenser has 5 supply compartments, numbered 1–5, starting from the rear of the machine. The compartments hold plastic supply cups that are used for either liquid or dry supplies. A nozzle

F232087

Operation

flushes supplies from the cups with water when called for in the cycle program.Theory Of Operation (Continued)

Liquid supplies can be injected directly into the cups by a customer-supplied external chemical supply system. Five hose strain reliefs on top of the supply dispenser facilitate connection to an external supply system. A terminal strip inside a compartment attached to the left side of the control module, viewed from the rear of the washer-extractor, provides connection points for external supply signals.

Operation

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 two-digit 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

Use left hand to press and hold the door unlock button located on the lower right front of the control panel. Use right hand to turn door handle clockwise and swing the door left to open. See Figure 2–3.

CAUTION

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

SW025

Load the machine to full capacity whenever possible, but do not exceed the rated dryweight 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.

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.

WARNING

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. The machine should not start or run unless the door is both closed and locked.

SW024

Note: When washing items which may disintegrate or fragment, such as mop heads or sponges, use laundry nets to prevent drain blockage.

Supply Dispenser

Supplies are placed in the supply dispenser compartment cups prior to the start of each cycle.

Liquid supplies can be injected directly into the supply dispenser by an external chemical supply system.

Note: Supply dispenser compartment cups must not be removed when an external chemical injection supply system is attached to the washer-extractor.

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.

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.

Cycle Execution (Continued)

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.

extract speed while the spray rinse nozzle mounted in the door sprays a fan-shaped stream of cold water into the basket.

Wash

Standard Wash

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

The standard wash agitation sequence:

• 12 seconds counterclockwise at

wash speed

• A 3-second pause

• 12 seconds clockwise at wash speed

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.

Spray Rinse

Fill segments 1–5 can be designated as spray rinse segments on standard models. During a spray rinse segment, the basket rotates at

• 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.

F232087

Operation

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.

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.

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.

Note: If the water does not reach the programmed temperature in 30 minutes, the computer progresses to the wash step.

Drain

At the conclusion of a spin, the drain valve opens, and the cylinder turns clockwise (forward) at wash speed.

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

F232087

Operation

Cycle Execution (Continued)

Stop Routine

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

The stop routine sequence:

Note: If the display shows “donE” and the basket rotates clockwise for an abnormally long time, this indicates that either the water has failed to drain properly from the machine, or that the water level switch has failed. The door unlock button will not be activated until this problem is fixed.

• All inputs are turned off.

• A 40-second coast-down (if stop routine is

preceded by a spin)

• 12 seconds clockwise (forward) 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 counterclockwise (reverse) at wash speed

• A 5-second pause

• The display shows “donE.”

• The door unlock button is energized,

allowing the door to be opened.

LOLE Low Level

Note: The computer does not count down the remaining cycle time during fills, drains, or prior to first achieving the programmed heat temperature when heating. The computer resumes counting down cycle time once the programmed fill level is reached, when the machine has drained, and after a programmed heat temperature is reached.

HILE High Level

Note: If “FLUS” is selected for a prewash segment, this selection will be skipped for that segment. The display will skip to step 9 in the programming process.

Note: Do not program heat steps for machines

not equipped with auxiliary heat. The machine will pause for 30 minutes during any step in which the fill water temperature does not already equal or exceed the programmed value of the heat step.

Note: Do not program auxiliary heat in a prewash segment containing a flush step.

SUP5 Supply 1 and 2

SUP6 Supply 2 and 3

SUP7 Supply 3 and 4*

*This is available only if supply 4 is enabled.

Note: External supply signal 5 is energized and supply dispenser compartment 5 flushes whenever a Supply 4 or Supply 7 (Supply 3 and Supply 4 combined) is called for in a program segment.

10. Press the Start key.

11. If the machine is equipped with an auxiliary heating system and the corresponding SETUP option is enabled, use the Up or Down key to select the desired segment temperature. To disable auxiliary heat for this segment, set this value to zero.

12. Press the Start key.

13. Use the Up or Down key to select the

desired spin time. Set this value to zero to skip the spin step. Press the Start key. The display will now show the identifier for the next program segment.

Note: An automatic 40-second coast-down follows every high-speed spin. For all spins except the final spin, this coast-down occurs during the fill for the following segment. Therefore, cycle time is not increased for coast-downs following all but the final spin.

14. Press the Stop key at any time to complete

the cycle programming procedure.
