Section 2

Installation & Operation

All washers must be installed in accordance with all local, state and national building, electrical, and plumbing codes in effect in the area.

Foundation Requirements

The washer must be securely bolted to a substantial concrete floor, or mounted upon a suitable base which is in turn securely bolted to a substantial concrete floor. Care must be stressed with all foundation work to insure a stable unit, eliminating vibration. All installations must be made on sound concrete floors 6" or thicker.

Mounting

A concrete pad or steel base which elevates the machine 4 to 6 inches above the floor level is recommended to provide easy access to the loading door. Allow a minimum of 24" of clearance behind the rear of the machine for service.

Mounting Holes

The following pages illustrate the mounting dimensions for the machine and also show a typical concrete pad arrangement.

Thoroughbred 400

Mounting hole dimensions are shown as either 14 1/2 or 17 1/8 inches front to back spacing. The 17 1/8 spacing is preferable unless current anchors dictate the 14 1/2 spacing. All 6 mounting holes may be used.

Thoroughbred 600

There are four mounting holes in the 600 and of course all must be used.

Note: Mounting bolts should be checked frequently to insure that they are still tight. The machine should be checked with a spinning load to be sure there is no unusual vibration or movement between the machine and the base or floor.

Plumbing

Water supply hoses are furnished with each machine. The threaded connections on the hoses are standard garden hose type thread. Separate hot and cold water lines with shut off valves or faucets for inlet hose connections must be provided, maintaining 30 to 60 p.s.i. water flow pressure. The hot water recovery rate necessary will depend on the length of the cycle and the specific program selected. A hot water temperature of 140 degrees Fahrenheit is recommended for best washing results.

Drain

The drain outlet tube at the rear of the machine is 3" in outside diameter. A flexible hose (Pt. No. 9242-417-003) is available to extend the drain system. Adequate fall must be maintained for proper drainage.

Protective Film

The machine may have protective adhesive film on the front escutcheon area and the front and side stainless steel panels. The film may be peeled off before putting the machine into service.

12

Electrical (includes chemical pump connections)

Dexter WCN25 and WCN40 series washers are intended to be permanently installed appliances. The machines should be connected to an individual branch circuit not shared by lighting or other equipment. The electrical connection should be sheathed in water proof flexible conduit, or equivalent, with conductors of the proper size and insulation (suggested size below). A power cord is not provided.

The following diagram shows the proper power connections to the rear terminal block for both 1 and 3 phase machines. Wiring should be performed by a qualified person.

Electrical power connections are made to the terminal block located at the upper left-rear corner of the washer. The terminal block is accessed by removing the cover.

1 Phase, 220-240 volts, 60 Hz.

Liquid Chemical Connection

In the left rear corner of the washer is the chemical injection assembly. This is where all chemical hose connections are made. The chemical hoses should be inserted into the round pvc pipe a minimum of 8" and a maximum of 12" on the T-400 and a minimum of 14" and a maximum of 18" on the T-600 to eliminate chemical buildup in the pipe and/or restrict water flow to the tub.

Final Check out

After all mounting, plumbing and electrical work is completed, the washer should be run through a cycle and checked for water leaks and proper functioning.

Note: 3 Phase Machines- Spin must be Counterclockwise viewed from the front of the machine. If spin is clockwise , the power wires going to L1 and L2 on the power terminal block TB-1 should be switched.

Section 3

Wiring Schematics

Start Circuit

Power travels into the control trough on L1 &L2 (3 phase) or L1 &N (1 phase). On 3 phase, 240VAC goes to a

Control Transformer that steps the voltage down to 120VAC AC for the controls. 120VAC then travels to the On/Off

Switch. If On is selected 120VAC travels to the 1.5 amp Circuit Breaker. On 1 phase, 120VAC goes directly to the

On/Off Switch and then to the 1.5 amp Circuit Breaker. There is no need for a step down transformer on 1 phase.

From the Circuit Breaker, 120VAC travels on the white/red wire to the Main Timer Start and On-Off Contacts. The

Start Contact is closed before the machine has been started so 120VAC travels through the Start Contact and is supplied to the Advance/Start Switch. When the Advance/Start Switch is closed 120VAC is supplied on the orange/white wire to the Rapid Advance Timer Motor. This timer motor starts advancing the Main Timer to the preselected starting position. The On-Off Contact in the Main Timer closes and provides 120VAC to the S1 Door Switch.

The On-Off Contact also provides 120VAC to the On Light on the red wire. With the S1 Switch closed (door is latched) the Door Lock Solenoid is now powered with 120VAC via the white/red wire. The Door Lock Solenoid pulls in, locking the door and closing the S2 and S3 Switches. The S2 Switch is a backup to the S1 Switch so that the adjustment on S1 isn't as critical. The S3 Switch provides 120VAC to Timer Contacts RA-1,2,3,4 to power the Rapid

Advance Motor again (if 2 Flushes are not selected) and the Main Timer is allowed to advance on to the preselected start position. The blue wire furnishes the neutral for the controls.

17

Fill Circuit-Warm

120VAC is supplied to the controls through the S1, S2, and S3 Door Switches. The On Light and the Door Lock

Solenoid (discussed in Start Circuit) will remain on throughout the cycle. The Lock Thermoactuator Contact in the

Main Timer is closed and provides the neutral side to operate the Lock Thermoactuator. This contact cycles open and closed keeping the Lock Thermoactuator activated until 1 1/2 minutes before the end of the cycle. At this point the contact opens and removes power to the Lock Thermoatuator. 120VAC is provided to the Lock Thermoactuator on the orange wire from the S3 Door Switch. The Drain Contact in the Main Timer is closed and provides 120VAC to the Drain Valve on the brown/yellow wire which closes the valve. The Wash Motor Contact in the Main Timer is closed and provides 120VAC to the Reversing Timer and the Reversing Timer Motor on the blue/black wire. This will start the Reversing Timer operating which will alternately open and close the Micro Switches that provide the direction of tumble for the wash basket. Depending on the cycle selected either the Wash Light Contact, the Prewash

Light Contact, or No Contact (1st Flush) in the Main Timer is closed and provides 120VAC to these Lights. The orange wire coming from the S3 Door Switch provides power to the Wash Water Contact in the Main Timer as well as the High Water Level Contact. 120VAC connects from the Wash Water Contact to the Wash Temperature

Contact via an internal timer connection.

Now a water temperature must be selected with the Temperature Selector Switch. We'll use #2 Warm. The washer fills the tub through the back of the machine with both the C1 Cold and H1 Hot Water Valves. 120VAC travels from the Wash Water Timer Contact to the #1Contact in the Selector Switch via the white/black wire. 120VAC goes through the closed #1 Contact in the Selector Switch and energizes the C1 Cold Water Valve Solenoid via the white/orange wire. 120VAC also travels to the closed #4 Contact in the Selector Switch. This closed contact provides power to the H1 Hot Water Valve Solenoid via the red/yellow wire. The neutral for the Water Valves & Main

Timer Motor is provided through the Pause/Run Switch & through the Motor Overload Protector. The Main Timer is stopped until the Pressure Switch provides neutral when low level is reached.

As the washer fills with water, the Wash Basket will tumble one direction for 19 seconds, pause, and then reverse direction for 19 seconds. All Flushes and Rinse 1, 3 & 4 are high level. Wash, Rinse 2 & Final Rinse are low level.

For a high level bath 120VAC travels from the timer High Water Level Contact on the green/white wire to the R4

High Water Level Relay. When energized, the R4 High Water Level Relay opens the neutral yellow wire from the low level side of the Pressure Switch & closes the violet/yellow from the high side. When the water reaches the predetermined level the Pressure Switch moves to the full position and opens the neutral side of the line to the

Water Valves.This shuts the Water Valves off.

Wash Circuit

As the washer fills the tub through the back of the machine with either one or both the C1 Cold and H1 Hot Water

Valves, the Wash Basket will tumble one direction for 19 seconds, pause, and then reverse direction for 19 seconds.

This is accomplished through the use of a Reversing Timer. 120VAC is supplied to the Reversing Timer Motor on the blue/black wire from the Wash Motor Timer Contact in the Main Timer. The Reversing Timer will alternately open and close the two Wash Micro Switches and provide 120VAC to the R1A (brown/white wire) and R1B (orange/green wire) Wash Contactor Coils. These coils open and close the Contactor Switches to operate the Drive Motor.

As discussed in Start and Fill, the Lock Thermoactuator, Drain Valve, On Light, and Main Timer Motor (except in fill) are all operating throughout the Wash Cycle.

Liquid Chemicals Injection Pumps receive 120 volt signals from the terminal strip on the back of the washer.

These are labeled A, B, C, &D. (A-Prewash, B-Wash, C-Rinse 2, D-Final Rinse)

18

Drain, Rinse 1, 2, 3 & 4 & Final Rinse Circuit

The Drain Contact on the Main Timer opens removing power to the Drain Valve. The normally-open spring-loaded

Drain Valve opens and empties the tub.

For Rinse 2, 3 & 4 the Rinse Light Contact in the Main Timer closes and provides 120VAC to the Rinse Light. The

Rinse Water Contact in the Main Timer also closes and provides 120VAC to the C1 Cold Water Solenoid and through the Rinse Temp Contact to the H1 Hot Water Solenoid (Except when cold #4 is selected). The tub will fill until the predetermined level is achieved at which time the Pressure Switch Contact will open the neutral side of the line shutting off the C1 Cold Water Solenoid and H1 Hot Water Solenoid.

For the Final Rinse, the Final Rinse Light Contact in the Main Timer closes and provides 120VAC to the Final Rinse

Light. Rinse water is the same as in Rinses above.

The Hot Rinse Contact provides 120VAC to the R5 relay on the brown/red wire. This opens the circuit to the C1

Cold Water Solenoid when Temperature Selector Switch #1 or #2 is depressed.

Extract Circuit

The Wash Motor Contact remains closed and provides 120VAC to the closed Clockwise Micro Switch on the

Reversing Timer. 120VAC is then fed to the Counter Clockwise Micro Switch via a jumper wire. Power is then sent through the Counter Clockwise Micro Switch to the Delay Spin Micro Switch. The Delay Spin Micro Switch provides

120VAC to the Spin Motor Contact in the Main Timer on the blue/white wire. The Spin Motor Contact is closed for spin and the voltage continues on to the R2 Spin Motor Contactor Coil on the red/black wire and to the Spin Light on the yellow/red wire. With 120VAC to the R2 Spin Motor Contactor Coil the Contactor is pulled down (closed) and two things happen. With the R2 Contactor closed, 120VAC is now provided from the orange wire directly to the

Contactor eliminating the Reversing Timer and the Micro Switches from the circuit.

The second thing that happens when the R2 Contactor is closed is that voltage is provided directly to the Spin

Winding in the motor on 3 phase machines and the washer spins.

On 1 phase washers, the R2 Contactor provides 120VAC to the Main Spin Winding and also provides 120VAC to the Solid State Start Switch Terminal #2. 120VAC goes out of the Solid State Start Switch on the #3 Terminal to the

Spin Capacitor. The Spin Capacitor then provides 120VAC to the Phase Spin Winding until the Spin Motor comes up to speed. Within a few seconds of start up, the Solid State Start Switch senses that the Spin Motor Current has dropped (motor is up to speed) and opens the circuit on #3 Terminal on the Solid State Start Switch. This eliminates voltage to the phase winding (start winding) and the motor continues to run on the Main Winding.

The Lock Thermoactuator Contact in the Main Timer opens 1 1/2 minutes before the end of the cycle removing the neutral to the Thermoactuator. This allows the Thermoactuator time to retract by the end of the cycle.

To insure that the Lock Thermoactuator has retracted by the end of the cycle, 1 minute prior to the end of the cycle, the Unlock Thermoactuator is powered with 120VAC through the Unlock Thermoactuator Contact in the Main Timer.

The Spin Motor Contact in the Main Timer opens, stopping voltage to the motor. The basket will coast to a stop. The

Wash Motor Contact in the Main Timer closes providing power to the Reversing Timer once again (discussed in

Wash Cycle). The washer will tumble for approximately 30 seconds to let the clothes shake loose and then stop.

The neutral for the Main Timer Motor is provided through the Delay Fill Timer Contact.

End of Cycle Circuit

The On-Off Contact in the Main Timer opens removing power to the Door Lock Switches and Contactors. The machine is now stopped. The Start Contact on the Main Timer is closed providing 120VAC to the Advance/Start

Switch on the white/green wire. The machine is now ready to start a new cycle.

Service Procedures

Before performing any service work, remove electrical power from the machine.

Always replace panels before putting machine into service.

Top Panel Removal

A.

Remove 4 screws that hold detergent dispenser to top panel.

B.

C.

Unlock top panel lock.

Raise top panel, slide to the rear to release from back clips and lift off.

Detergent Dispenser

Remove top panel to access dispenser. (see Removing Top Panel)

Detergent is flushed from the front of the compartment and fabric softener is flushed from the back. There will be a small amount of water left in the fabric softener compartment after each use. This is normal.

Vacuum Breaker

In the left rear of the cabinet is the vacuum breaker. It guides the water to the tub and dispenser and prevents a back flow of water.

Chemical Injection Assembly

In the left rear corner of the washer is the chemical injection assembly. This is where all chemical hose connections are made.

Water Valves

Remove top panel to access water valves. (see Removing Top Panel) The two dual outlet water valves are mounted to the rear channel with two screws each. The hot water valve is black in color designating that it is for higher temperature hot water. The cold valve is blue in color designating that it is for lower temperature cold water. Always check inlet screens to be sure that they are clean. Disassembly requires the removal of two solenoid screws and three valve body screws. Below the solenoid coil is a solenoid guide, armature, armature spring and diaphragm. All valve parts are available individually or as a complete unit.

25

Circuit Breaker

The circuit breaker mounts to the rear channel. It carries all of the controls in the machine but does not include the motor. To reset the circuit breaker just push in the button.

Control Mounting Trough

Remove top panel to access control trough. (see Removing Top Panel) It sets on the right side of the machine and holds many of the controls.

Reversing Timer

The reversing timer operates the wash and spin relays and is mounted on the left side of the control trough with two screws. It has three cam operated switches. Two switches operate the wash cycle by alternately engaging the wash relays to tumble counter clockwise for 19 seconds, stop for 3 seconds, reverse direction and tumble clockwise for

19 seconds. The third switch engages the spin relay for the high speed spin portion of the cycle.

R1A Wash Motor Relay (clockwise direction)

This relay is mounted in the center of the control trough. It is the rear one of the three large relays. It closes the circuit to the motor for clockwise wash speed. Wires are removed using a straight blade screwdriver. The relay is removed by prying out on the mounting tab at the bottom of the relay with a straight blade screwdriver.

R1B Wash Motor Relay (counter clockwise direction)

This relay is mounted in the center of the control trough. It is the middle one of the three large relays. It closes the circuit to the motor for counter clockwise wash speed. Wires are removed using a straight blade screwdriver. The relay is removed by prying out on the mounting tab at the bottom of the relay with a straight blade screwdriver.

R2 Spin Motor Relay

This relay is mounted in the center of the control trough. It is the front one of the three large relays. It closes the circuit to the motor for spin speed. Wires are removed using a straight blade screwdriver. The relay is removed by prying out on the mounting tab at the bottom of the relay with a straight blade screwdriver.

R4 High Water Level Relay

This relay is the rear one of two clear relays located directly in front of the motor relays. The Main Timer provides

120VAC to the R4 High Water Level Relay coil. It closes the circuit from the pressure switch coming out of the high level contacts for the various high level baths in the cycle. It also opens the circuit coming out of the low level contacts.

R5 Hot Rinse Relay

This relay is the front one of two clear relays located directly in front of the motor relays. The Main Timer provides

120VAC to the R5 Hot Rinse Relay coil. It opens the circuit to the cold water valve so that specific rinses are hot water only.

Program Timer

This timer is located on the left side of the control trough directly behind the reversing timer and is held in place with two screws. It controls most machine functions. There are two drive motors on the program timer. The one towards the front of the machine advances the timer at the beginning of the cycle. The timer motor towards the rear drives the timer throughout the cycle. These two motors can be replaced individually. The program timer has a black knob that allows the timer to be manually turned to any portion of the cycle for diagnostic purposes.

Note: All single phase 25lb. and 40lb. washers have an electronic start switch and run and start capacitors. Three phase machines do not require these parts.

Always discharge capacitors before servicing.

26

Solid State Start Switch (single phase only)

This switch is located on the right side of the control trough directly behind the coin accumulator transformer. Its job is to switch the spin start capacitor on at the beginning of spin and to switch the spin start capacitor off when the motor achieves operating speed. To test the electronic start switch, clamp an ammeter around either single lead wire to the start capacitor (capacitor with plastic case). The switch should show starting current flow in the capacitor circuit momentarily at the start of spin. Continuous current flow means that the electronic start switch is stuck on and has failed. No current flow means that the switch is open and has failed.

Capacitors (single phase only)

The capacitors are located in the right rear corner of the control trough directly behind the start switch. The capacitor with the metal case is the wash run capacitor and the capacitor with the plastic case is the spin start capacitor.

Note: All 60 Hz. three phase washers have a controls transformer. Single phase washers do not require a controls transformer. Always check the incoming voltage and use the appropriate transformer terminal when installing three phase washers.

Controls Transformer (three phase only)

This transformer is mounted at the back of the control trough and steps a range of 208 to 240 volts down to 115 volts for the controls. There are two terminals on the controls transformer for incoming power. One terminal is for

208 to 220 volts and the other is for 221 to 240 volts.

Pressure Switch (Dual Level)

The pressure switch sets the water level in the washer and is located in the left rear corner of the control trough. As the water level rises, it compresses the air in the pressure switch hose. When the washer reaches the desired water level, the compressed air in the pressure switch hose opens the contacts in the switch, shutting off the water. When at the empty level, the pressure switch contacts are closed allowing the machine to either spin or fill with water. At low level the water will be approximately 1/2" up from the bottom of the door glass. On high level the water will be approximately 3"-4" up from the bottom of the door. The pressure switch is sealed and is not adjustable.

Power Connection Terminal Blocks

These terminal blocks set in the right rear corner of the washer and are accessed from the back. Incoming power to the washer and all electrical signals for chemicals should connect here. (see Electrical under Installation and

Operation Section for exact connections)

Cycle Indicator Lights

The 120VAC indicator lights are mounted to the back of the control panel and are held in place with two tabs. They are removed by squeezing the tabs with a screw driver. The lights are replaced as a complete unit.

Temperature Selector Switch

The push-button temperature selector switch is mounted on the right side of the control panel and is held in place with two nuts. It allows the selection of hot, warm or cold water temperatures.

Note: Do not over tighten on reinstallation as the switch can be damaged.

Cycle Selector Switch

The rotary cycle selector switch is mounted to the left of the temperature selector switch and is held in place with 2 phillips screws. It allows the selection of 4 different wash cycles.

27

Rocker Switches

These switches can be replaced individually by squeezing the tabs on the back side and pressing them out the front of the panel.

A.

Top switch is red and controls Off and On. This switch must be in the on position for the washer

B.

to operate. The off position will cause the washer to stop in the cycle and drain the water.

Middle switch is white and controls Advance and Start. This switch must be held in the start

C.

position momentarily to start a cycle. Wash and rinse baths can be advanced through by holding the switch in the advance position.

Bottom switch is blue and controls Pause and Run. This switch must be in the run position for the washer to advance through the cycle. The washer can be stalled at any point during the cycle for extended soaks by selecting pause. The door will remain locked and the drain valve will remain closed keeping the water in the tub.

Lower Service Panel Removal

Remove 2 screws and pull forward to disengage from the locator studs.

Drain Valve

The drain valve is a ball type and is powered closed by the drain valve motor. It is mounted under the washer tub on the left side. It is spring loaded open. If power is interrupted to the washer, the motor releases the sealing ball, allowing the drive spring to open the valve. With the valve open, all water in the washer will drain out.

Service

For access to drain valve, remove lower service panel.

Cleaning

A.

B.

C.

D.

E.

Loosen the clamp on the tub hose at the drain valve end and remove the hose from the drain valve.

Loosen the drain hose clamp on the back of the drain valve.

Unplug the wiring after the drain valve is removed from the washer.

Front Panel Removal

A.

Remove 2 screws between front panel top and front channel (located behind control panel).

B.

C.

Remove the two screws in the middle of the front panel.

Pull panel out at the bottom to about a 45 degree angle to detach the top lip and remove.

Masking Ring (door lock cover) Removal

A.

Remove front panel.

B.

C.

Remove nuts that retain masking ring.

Move it to the left and off.

Door Locking Solenoid

The door locking solenoid is powered shut with control voltage to lock the door and releases when voltage is removed. It is located in the left front corner of the washer.

Thermoactuators

The thermoactuators are a safety device that keeps the door from immediately unlocking if power is lost while the machine is operating. They are mounted under the door locking solenoid.

Lock Thermoactuator

Control voltage is applied to the lock thermoactuator at the beginning of the cycle making it extend and block the door locking solenoid. This keeps the door locked for approximately two minutes after a power failure occurs. The lock thermoactuator does not delay the door opening at the end of a normal cycle.

Unlock Thermoactuator

To insure that the lock thermoactuator has retracted by the end of the cycle, one minute prior to the end of the cycle, the unlock thermoactuator is powered with control voltage making it extend and unblock the door locking solenoid.

28

Door Lock Assembly

After removing the front panel and trim ring, the door lock assembly can now be accessed.

Operation

After loading the clothing, the door should be closed and latched. The locking cam on the door contacts the latching switch actuator which closes the latching switch. The specified number of coins should now be added to start the washer. This satisfies the coin accumulator which powers the timer rapid advance motor. A timer contact provides power to the latching switch and with the door latched, the power travels through the latching switch to the door lock solenoid. This solenoid pulls up on the locking pawl by use of a linkage rod. The locking pawl has two jobs. The first is to lock the door. This is accomplished by blocking the locking cam on the door so that it can't rotate to unlock.

The second job is to close the two piggyback lock sensing switches. These switches control power to all of the controls. If the door unlocks for any reason, these two switches will stop the machine. When the door handle is 1/4 to 1/2 of an inch from its fully closed position, the latching switch should close. The two piggyback lock sensing switches should be open when the door is unlocked and should be closed when the door is locked.

Adjustment

The latching switch and the piggyback lock sensing switches all have slotted mountings for easy adjustment.

1. Set door cam over pin.

2. Tighten spring screww on switch actuator arm until it just clears cam OD.

( Note : Spring screw will have approx. 1/8" thread exposed at end beyond nut.)

3. Set .040 thickness gage between arm and latch switch operator.

4. Swivel switch until it clicks closed. Back it up just until it clicks for a reset. Tighten in that position.

Check again for close and rest with gage in place. Remove gage.

5. Check for switch actuation at partial turn of cam as in operation above.

6. Check that lock arm swings by cam lobe to lock position when switch just clicks.
