GENERAL INSTRUCTIONS

(INSTALLATION / DIMENSIONS) FOR 100B, PRB SERIES
NOTE: Read the following instructions carefully. Proper installation of your Jackson Dishwasher will assure proper
machine operation.

1. Open side doors, the front door (hook open) and remove dish, cup, and glass racks, and set to one side for
later use. Remove the tape holding the overflow strainer, the pump intake strainer, the wash head assembly
and the rinse head that are inside the machine.

2. Cut straps holding machine to base of crate, ease machine on to floor and slide into place of installation.

3. Connect drain to bottom of machine (1 1/2" IPS female fitting on bottom of wash sump) with proper slope to
conform with local and/or national codes. Drain is a gravity feed system from machine.

4. The incoming water line to the unit must be 3/4" with the capacity to supply 12 gallons per minute with a flow
rate of 20 PSI. The temperature at the unit must be 140° F. • This connection is just before the Y-strainer.
Connect to conform with local and/or national codes (STANDARDS).

5. Electrical connections should be made through hole in bottom of control box to terminal board inside (to the
right lower side of control box). This terminal board is accessible by removing the lower cover plate on control
box. The terminals are marked L1, L2 (requiring 208-230V, single phase), or L1, L2, L3 (requiring 208-230V,
three phase). There is a grounding lug inside of the control box on the bottom left. Be sure all connections
made are tightened properly. Refer to data plate for Voltage and Amperage totals and whether machine is
designed for 50 or 60 cycle operation.

6. Install the proper circuit breaker, wire, and conduit size to conform with local and/or national codes. Refer to
data plate for electrical loads.

7. DO NOT APPLY POWER UNTIL STEP 10.

8. Insert pump intake strainer and overflow strainer, then close door.

9. Turn on hand valve controlling water supply to machine; check for any leaks in plumbing
and connections.

10. To energize electrically, proceed as follows:

a. Turn on customer's circuit breaker controlling machine.

b. Check voltage at incoming terminal L1, L2, and L3 (if applicable). It should match

data plate voltage. Voltage at L1 and L2 should be checked to ground individually to
ensure that a high (or wild) leg is not connected to L1 or L2. (Voltage exceeding 150V
to ground would indicate high leg).

c. If voltages are in required range, turn on 15 amp circuit breaker on side of control box.

The 15 amp circuit breaker protects and controls the motors and control circuit only;

it is not meant to protect or control the rinse heaters.
d. Insert a rack into the machine and close all doors.
e. Turn on the master switch; this supplies voltage to the operating controls. Then lift up on the rinse/fill

switch. The unit will automatically fill the wash tub with water to a specific level.

f. Open the front door and check the water level. It should be 1/4" below overflow level.

If not, close doors, check the incoming water line making sure that the solenoid valve
fully opens and closes as the switch is turned on and off.

g. If the water is at the proper level, with the front door closed, turn. on the heat switch.

Observe the temperature gauges; the rinse temperature should rise to the specified level
of 180° within five minutes if the incoming water temperature is 140° to the booster

tank.

h. The wash heater will take longer to reach 150°F, as the element is designed for maintaining

temperature, not heating.

i. Turn the manual wash switch on with the door closed. You should hear the water being pumped as it

strikes the top of the machine. Turn off the manual wash switch.

j. The unit is now ready to proceed with the washing of dishes in accordance with the

operating instructions in this manual, and the instruction sticker on the front door of

the dishwasher.

GENERAL INSTRUCTIONS

(OPERATION) 100B, PRB

READ INSTRUCTIONS CAREFULLY: Proper operation of your Jackson Dishwasher will assure clean and
sanitized glasses and dishes at optimum efficiency.

DISH PREPARATION

1. Scrape the dishes thoroughly.

2. Pre-rinse the dishes by soaking or by spraying off with a pre-rinse hose.

3. Place the dishes and cups in the dish rack with the cups upside down.

4. Place the glasses and silverware in the combination glass-silverware rack with the glasses upside down.
Scatter the silverware loosely on the bottom of the rack. Do not put glasses on top of the silverware.

NOTE: When silverware is in an upright position, it washes and rinses better than lying flat. These compartment

silverware racks are available through your dealer or service agency.

MACHINE OPERATION

1. Open the front door and insert the pump intake strainer and overflow strainer.

2. Close all of the doors.

3. Turn the master switch on. Lift the rinse/fill switch up and release. The machine wilt now automatically fill
the wash tank and energize the wash and rinse heater control circuit.

4. Turn on the heat switch, letting the temperatures rise to the required temperatures on the wash (150°) and
rinse (180-195°) gauges.

5. Raise up the side doors. Slide in a rack of dirty dishes.

6. Add detergent* (see Detergent Recommendation). If an automatic detergent dispenser is used, follow the

manufacturer's instructions.

7. Lower all of the doors.

8. Start the automatic wash and rinse cycle of the dishwasher by flipping the start switch in a full up or down

position. For the next cycle, the switch must go in the opposite direction all of the way. The center position is
off. The light in the top center of the panel will go on when the cycle starts.

9. When the light goes out, open the side doors, slide out the rack of clean dishes, slide in

another rack of dirty dishes, and then repeat steps 6,7. and 8.

10. At the end of a meal period or the end of the day, shut off the heater switch and the master switch. Drain the
machine by removing the overflow strainer. Clean both strainers, the overflow and the inside strainer, of all
foreign debris and build-up and flush out the unit.

*DETERGENT RECOMMENDATION AND RINSE ADDITIVES: We suggest you contact your local detergent
specialists for the correct detergent and rinse additives for the area. To help until one can be reached, we suggest
that you use a non-foaming dishwasher detergent, approximately one-quarter cup in wash tank, when machine is
filled the first time, then one level table-spoon each cycle (or load) thereafter. This may have to be increased or
decreased to obtain satisfactory results.

When manually dispensing powdered detergent in wash tub always distribute over a sufficient area to prevent build
up. Some detergent, when dispensed in a small or concentrated area. may cause deterioration of the stainless tub
or sump.

TIMER FOR MODEL 100 DISHWASHERS

General Description

The timer is a self-contained (frame-mounted) timer of the repeating cycle type. It is mounted on
the control panel of Jackson Automatic Dishwashing machines, to control the automatic functions of
these machines. It consists of a clock motor which operates on 60 cycle AC, 220 VAC. In addition to the
clock motor, the timer also contains a driven cam arrangement which operates three micro switches.

Principle of Operation

The timer controls various operations of the automatic washers as per wiring diagram for each
machine, however, the timing cycle and the micro switches are the same for each model. The time for
ONE COMPLETE REVOLUTION of the cam shaft is approximately 120 seconds, allowing two wash
and two rinse operations for each complete revolution of the cam shaft. The micro switch nearest the
timer motor is the hold circuit and uses both the NO and NC contacts. The middle micro switch controls
the wash and uses the NO contact. The micro switch farthest away from the timer motor controls the
rinse and uses just the NC contact.

Service Instructions
CAUTION: ALWAYS REMOVE THE POWER TO THE MACHINE BEFORE WORKING ON THE

CONTROL PANEL OR WHILE SERVICING THE COMPONENTS ON THE SWITCH
PANEL. ALL ELECTRICAL CHECKS SHOULD BE MADE BY QUALI-FIED PERSONNEL.

Timer operation can be observed after removing the control panel from the control box by
loosening the four screws holding it. Hang the control panel using the two right hand screws with the
back side of the panel outward.

If it is determined that the timer is defective, it is recommended that a new timer be in­stalled. However, limited field maintenance can be accomplished as follows:

A frozen contact on a micro switch will be indicated by one function being executed all the time or
the absence of a click when the switch arm is actuated. The micro switch is replaced by:

1. Remove all wires from the timer, properly tag them to assure proper replacement.

2. Remove the two screws which hold the timer to the control panel.

3. One screw holds the micro switches, cams and actuating arms in the frame. This screw
is seen on the side opposite the motor. Remove this screw. NOTE: Be sure to note which
cam goes with which micro switch. Cam nearest timer motor has % raised, cam center,
larger depressed areas, cam farthest from timer motor, smallest depressed areas.

4. The unit can now be taken apart and the defective micro switch replaced.

5. Reassemble. NOTE: The flanges on the cams are such that they only mesh in one
direction. The shorter flange on the cams always points toward the drive motor.

The timers cam drive system is equipped with a clutch to enable one to view the operations of the
cams and micro switches. Remove power to machine BEFORE touching timer. Rotate cams by turning
with fingers; cams will turn in one direction only. Do not force them. As cams actuate switches, listen
for the click of the switch or test the switches with an ohmmeter.

10

DEFECTIVE TIMER MOTOR

A defective motor is indicated by the fact that the cams do not rotate or the machine does not perform the
automatic operations or performs a specific part of the cycle continuously, but works okay on manual. Remember, the
timer motor is controlled by the start switch and the hold micro switch, check this complete circuit before changing
motor. The motor is replaced by:

1. Remove motor leads from connection points.

2. Remove the two screws which hold the motor.

3. Replace with new motor.

4. Re-connect motor leads to proper points.

NOTE: It may be necessary to remove complete timer to replace motor; if so, follow steps 1 and 2 previous page.

Rated 15 amps, controls power to control circuit only, I.E. timer, relays. solenoid valve,
water-level control and motors. Circuit breaker does not cutoff power in control box at
incoming terminal board and rinse heater or its relay contacts. Power is still applied to them

when the circuit breaker is in "off" position.

This switch interrupts all power going to the control circuit, this means that all switches on

control panel are inoperable until master switch is turned "on."

This switch controls the timer motor through two circuits (see electrical diagram) it is a three­position switch, up position = start, middle position = off, down position = start. To start, flip
switch toggle in either up or down position; indicating light in center of panel will light
verifying automatic cycle has started. After cycle ends and you are ready to start a new

cycle, flip toggle to opposite position.

This light comes on only when automatic cycle is in progress and extinguishes when cycle is

complete.

This switch is used to by-pass the timer and operate the wash pump manually. The wash
pump will run as long as this switch is "on." The prime purpose of this switch is to extend the
wash period for extremely soiled dishes before putting them through the normal automatic
cycle. It may also be used as an emergency back-up should the timer ever fail to operate.

The required wash time is indicated on the control panel (front).

emergency back-up in case of timer failure for rinsing dishes. The required rinse time is

indicated on the front control panel.

This switch completes the heat circuit which is composed of automatic control devices that

turn heaters on and off to maintain required temperatures.
This indicating light remains lit all the time the heat switch is on.

12

REPLACEMENT of SWITCHES in CONTROL

PANEL

There are five switches installed in the control box cover panel. These are the start, master, manual wash,
rinse/fill and heater switches.

Before working on machine, it is important that power be turned off at customer's circuit breaker to prevent the
possibility of electrical shock, trip breaker to "off" position. Then turn machine breaker "on" located right side of
control box.

Remove control panel from control box by removing the four screws holding it in place. Hang the control panel
using the two right hand upper and lower screw recepticles on the control box with backside of panel facing
outward. The five switches are mounted in individual round holes with a keyway. By using a pair of pliers or open
end wrench, it is possible to loosen the inside nut enough to allow the outside nut holding the switch to be removed
by fingers. Push switch out of hole.

If a switch is found to be defective, replacement can be achieved by placing the new switch next to the old one. To
make sure the new switch is not upside down. line up with the keyways. Transfer wires one at a time to the new
switch. If this is not practical, pull wires off, one at a time and tag them for proper replacement.

Put switches back into panel, make sure switch protrudes through panel properly, tighten both nuts, and replace
control panel on control box. Power can now be applied to dishwasher and run through cycles checking all
operations.

THERMOSTAT ADJUSTMENT

The thermostat can be adjusted by turning screw # 1 (see picture) on the thermostat control box cover.
(Remember the present setting, in case the problems are elsewhere in the control circuit.) A CW rotation is
used to obtain a lower temperature setting and a CCW rotation is used to obtain a higher temperature
setting. A 1/8 turn of screw # 1 changes the temperature approximately 15° F. If screw # 1 is turned all the
way to its stop in either direction; adjust screw #2 as follows. DO NOT TOUCH THE SCREW SEALED WITH
RED PAINT. When adjusting screw #2 power should be disconnected during adjustment.

Set screw # 1 so that it can be turned equal distances in either direction, then:

- - -if screw # 1 stopped while turning in CW direction, turn screw #2 in CW direction
slowly and only 1/8 of a turn or less per complete cycle of the unit.

- - -if screw # 1 stopped while turning in CCW direction, turn screw #2 in CCW direction
slowly and only 1/8 of a turn or less per complete cycle of the unit.

Three-fourth's of a turn will bring the thermostat to approximately the same setting obtained where
screw # 1 stopped. Check the present temperature setting before attempting any further adjustments. Use
screw # 1 for any further adjustments.

NOTE:

Making large moves in adjusting may cause misalignment
thus increasing the chances that further adjustment cannot be
made and the thermostat will have to be replaced.

NOTE: Some machines were equipped with factory preset
thermostats (wash: P/N 1700-W & rinse: P/N 1700-R) which do not
have adjustment screw #1.

RINSE TANK HEATER SYSTEM

FUNCTION

The Rinse Tank Heater System is electrically connected in the circuit so that it is dependent upon the
dishwasher being properly filled with and maintaining a safe water level. The automatic fill system, therefore, should
operate properly before the heat system can be engaged. The circuit is controlled by a heat switch (mounted on the
front control panel), a thermostat (mounted behind the lower front panel), a water level control (mounted in the
control box), and a heater relay (mounted in the control box), with the coil being activated by the thermostat.

INDICATORS OF POSSIBLE MALFUNCTION

Once the machine, has been properly filled and the heat system engaged, the heat circuit should operate by
merely turning on the heat switch. Should the rinse tank heat, be it either too high, too low, or no indication of
temperature at all, the following checkouts should be made.

CHECKOUT OF HEATER SYSTEM FOR RINSE TANK (Refer to drawing, figure 1)
NOTE: THE FOLLOWING CHECKOUTS SHOULD BE DONE BY A QUALIFIED SERVICE PERSON OR

ELECTRICIAN.

1. If temperature is too high: adjust thermostat, using thermostat instructions in this manual.

2. If temperature is too low, adjust thermostat as above, then:

a. Turn off power to machine by tripping customer circuit breaker to "off" position.

Turn off machine circuit breaker located on right side of control box.

b. Remove lower cover plate on control box (held by single screw).
c. Make sure rinse temperature is below 180° (preferably about 140°).
d. Reapply power. Turn on master switch and observe heat relay (4 pole mounted lower left inside control

box) while heat switch is turned "on" and "off". If relay contacts move in and out, see instructions under
"B"; if not, proceed with "A".

A. If heat relay does not close:

1. There is an insulated movable bar on the relay across the top of the four contacts. With insulated
probe, depress this bar and observe the rinse thermometer; the temperature should rise noticeably
in a minute or two. If it moves very slowly, it would indicate that one or more elements are faulty. If it
moves constantly higher at a good rate, elements are okay.

NOTE: A check with an amp probe at position E, if available, can be made. Each row of elements should draw 30
amps with a total approximate amperage draw of 60 amps for both rows of elements. (Single phase). Replace any
defective elements.

A. 2. With master and heat switches on:

a. Check position 1, figure 1. Voltage should be 220V; if not, checkout heat

switch and replace if necessary.
b. Check position 2; there should be no voltage.
If there is, readjust thermostat per thermostat adjustment instructions.

c. Check position 3; voltage should be approximately 120V to ground. d. If voltage being applied

on positions 1, 2. and 3 check out okay. then the relay should be replaced. Coil is probably defective.

16

B. If heat relay closes:

1. Check power supply at incoming terminal board L1 and L2. It should be 220V, approximately.

2. Check power at positions 4 and 5, figure 1. Voltage should read approximately 220V; if not,
check wires for breaks or bad connections.

3. Check power at positions 6 and 7. Voltage should be approximately 220V. If not, check wires for
breaks or bad connections.

4. Temperature should rise as explained in A1 and amperages may be checked according to those
instructions. Replace any defective elements.

FUNCTION

The Wash Tank Heater System is electrically connected in the circuit so that it is dependent upon the
dishwasher being properly filled with and maintaining a safe water level. The automatic fill system, therefore, should
operate properly before the heat system can be engaged. The circuit is controlled by a heat switch (mounted on the
front control panel), a water level control (mounted in the control box), a thermostat (mounted behind the lower front
panel), and a heater relay (mounted behind the lower front panel), and a heater relay (mounted in the control box),
with the coil being activated by the thermostat.

INDICATORS OF POSSIBLE MALFUNCTION

Once the machine has been properly filled and the heat system engaged, the heat circuit should operate by
merely turning on the heat switch. Should the wash tank be either too high, too low, or no indication of temperature
at all, the following checkouts should be made.

CHECKOUT OF HEATER SYSTEM FOR WASH TANK (Refer to drawing, fig. 2)
NOTE: THE FOLLOWING CHECKOUTS SHOULD BE DONE BY A QUALIFIED SERVICE PERSON OR

ELECTRICIAN.

1. If temperature is too high: adjust thermostat, using thermostat instructions in this manual.

2. If temperature is too low: adjust thermostat, using thermostat instructions in this manual.

3. If step one or two does not correct the problem, proceed as follows:

a. Turn off power to machine by tripping customer circuit breaker to "off" position.

Turn machine circuit breaker on right side of control box to "off".

b. Remove control panel from control box. Remount panel to right side, using two

screws, with the backside of panel facing you. c. Reapply

power to unit.
d. Wash tank must be emptied, then refilled for each checkout.
e. Wash temperature must be 130 degrees or less. Observe wash heater open switching

relay (two pole; only one pole used), located top relay on left side. With master

switch on, turn heat switch on and off; if relay contacts move in and out. see instructions

under BB. if not. proceed.

AA - - If heat relay doesn't close:

1. There's an insulated bar across the top of two contacts. With insulate probe, depress this bar and
observe wash thermometer; temperature should rise slowly. Watch for approximately five minutes; if
temperature doesn't rise, replace element. If amprobe E is used, the element should draw
approximately 7 amps.

2. With master and heat switches on:

a. Check position 1, figure 2. Voltage should be 220V. If not, check out and replace heat switch.
b. Check position 2; there should be no voltage. If there is, readjust thermostat

per thermostat adjustment instructions.

b. Check position 3; voltage should be approximately 120V to ground.
d. If voltage being applied on positions 1, 2, and 3 checks out okay, then the

relay should be replaced. Coil is probably defective.

18

BB - - If heat relay does close:

1. Check power supply at terminal board #2 between terminals #5 and #7; it should be approximately 220V.

2. Check power at position 4; there should be no voltage.

3. Check position 5; voltage should be approximately 120V to ground.

4. Check power at position 6; voltage should be 220V approximately; if not. check wires for breaks and bad
connections.

5. Temperature should rise as explained in AA1 and amperages may be checked according to those instructions.
Replace any defective elements.

REPLACING SEAL and

CERAMIC on WASH PUMPS

FUNCTION

The pump is part of the total motor-pump system and utilizes one shaft seal and ceramic to prevent
the pump from leaking around the impeller and shaft. One gasket is used to prevent leakage between the
pump mounting plate and the machine pump plate.

REPLACEMENT OF SEAL AND/OR CERAMIC

1. Remove the power source to the machine by turning the circuit breaker to its "off" position on the side

of the control box.

2. Drain the machine by removing the overflow strainer in the wash tank.

3. Support the motor - - remove the four nuts holding the pump/motor to the machine's pump plate.

4. Carefully pull motor outward, move from side to side as required to remove from machine.

5. Set motor and pump on a sturdy stand close to machine or remove wires and conduit to allow

motor/pump to be moved to a better work station.

6. Insert a firm object into the blades of the fan and use a 5/16" ratchet to remove bolt holding impeller.

After the bolt is removed, pull the impeller up and off of the shaft.

7. The ceramic is imbedded in the pump mounting plate and usually does not need replacement, but the
seal normally would when water leaks around the motor shaft area. If replacement of either is
required, proceed as follows:

a. Remove the four bolts holding the pump mounting plate to the motor.
b. Slide the mounting plate up and off of the shaft and motor. The imbedded ceramic and

shaft seal will be removed with the mounting plate.

c. Turn over the plate and push the seal and/or ceramic out of the housing carefully. It

may be necessary to break the ceramic to remove it.
d. Clean the hole where the ceramic was installed.
e. Lightly coat with a lubricant around the new ceramic's edges and "0" ring. Gently press

the ceramic into place against the snap ring in the housing. Make sure that the grooved

side of the ceramic faces the motor and housing snap ring, leaving the smooth side toward

the impeller.

f. Make sure that the woodruff key is in place in the shaft and then set the plate back on the

motor over the shaft.
NOTE: A field tool can be made (to ease installation of seal) from a pipe or tube (3/4" CPVC typical
example) that has proper outside and inside dimensions. It must fit over step down in shaft, but be
close to larger shaft size on outside. To accommodate woodruff, cut long slot in tube. Lubricate tube
slip seal over tube onto shaft.

g. Lightly coat with a lubricant the new seal face and gently press it into place over the shaft

with the seal face against the ceramic. SEE NOTE ABOVE.

h. Place the spring over the shaft with the metal cap up. Press the impeller down onto the

shaft, aligning the keyway of the impeller with the woodruff key.
i. Tighten the impeller washer, lockwasher, and bolt into place. Replace the four bolts
that hold the mounting plate to the motor.

8. Reinstall the pump and motor in the unit by reversing steps one through eight (it is suggested that a

new pump gasket be installed).

IMPELLER ROTATION:

WHEN FACING THE IMPELLER AFTER MOUNTING IT ON THE MOTOR SHAFT, THE
IMPELLER SHOULD TURN IN A CCW DIRECTION.

CERAMIC on RINSE PUMPS

FUNCTION

The pump is part of the total motor-pump system and utilizes one seal and ceramic to prevent the pump from leaking
around the impeller and shaft. One gasket is used to prevent leakage in between the pump mounting plate and the machine
pump plate.

REPLACEMENT OF SEAL AND/OR CERAMIC

1. Remove power source to machine by turning circuit breaker to its off position on side of control box.

2. Drain machine by removing overflow strainer in wash tank.

3. Support motor - remove the four nuts holding the pump/motor to the machine's pump plate.

4. Carefully pull motor outward, move from side to side as required to remove from machine.

5. Set motor and pump on a sturdy stand close to machine or remove wires and conduit to allow motor/pump to be moved to
a better work station.

6. Remove dust cap over end of motor shaft (opposite impeller end). This can be done by wedging with a screwdriver.

7. Remove impeller - hold shaft by inserting screw driver in slotted end of shaft and unscrew impeller in counterclockwise
direction.

8. The ceramic is embedded in the impeller and normally does not need replacement, but it should be checked for cracks or
a worn out surface. If ceramic does need replacement, proceed as follows.

(a) With a pointed, flat tool, work the ceramic and rubber cup out of groove in impeller.
(b) Clean groove of all residue.

(c) Apply small amount of adhesive in groove.
(d) Press new ceramic gently into groove with rubber cup leading the way. (NOTE:

THE CERAMIC HAS ONE SIDE THAT IS GROOVED. THIS SIDE SHOULD BE FACING DOWN INTO THE
RUBBER CUP. THE SMOOTH SURFACE SHOULD BE FACING UP).

9. The seal is embedded in the pump mounting plate and usually will need replacement when water leaks around motor

shaft area. If replacement is required proceed as follows.

(a) Remove four bolts holding pump mounting plate to motor, must be done with Allen wrench.
(b) Slide mounting plate up off of shaft and motor.

(c) Press seal out of housing carefully.
(d) Clean hole where seal was installed.
(e) Apply a small amount of non-hardening sealant to backside of seal. Insert new seal with a seal driver to prevent

ruffling the edges of seal. Never use screwdriver or similar tool to alternately force edge of seal in place.

10. Reassemble pump and motor by reversing the above procedure.

INSTRUCTIONS for ADJUSTING TENSION

of CANTILEVER

PROBLEM: Doors raise hard, but lower easily.

SOLUTION: 1. Back off (loosen) upper adjusting nuts (F) on both eyebolts (E) about two or three complete turns.

2. Tighten lower adjusting nuts (G) on both eyebolts (E) a complete turn.

3. Check door for easy operation. Adjust further, if necessary.

4. When adjustment is completed, tighten upper adjusting nuts (F) down against angle to lock in position. Check
both eyebolts.

PROBLEM: Doors raise easily, but lower hard.
SOLUTION: 1. Back off lower adjusting nuts (G) carefully, making sure there is still some thread on eyebolt available (both

eyebolts).

2. Check door for easy operation. Adjust further, if necessary.

3. When adjustment is complete, tighten upper adjusting nuts (F) down against angle to lock in position. Check
both eyebolts.

PROBLEM: Doors sticking, or are hard to move up and down.
SOLUTION: 1. Raise doors.

2. Clean inside door channels on machine with a good cleaning compound. It may be necessary to remove
doors to completely clean channel. If so, remove only one door at a time. Make sure cantilever has stop to
prevent pulling other door up and out of channel. If it does not have stop, secure cantilever arm to machine
with doors in the closed position.

3. Build up should be completely removed so it may be necessary to use an abrasive pad (non-metallic) to clean.

4. While you have the door out of channel, make sure it is not dented or crooked. If channel is crooked or
dented, use 1/2" wide block to spread to proper opening.

5. Clean nylatron runners on the doors or replace nylatron, if excessively worn. See instructions on door runners.

6. Check door channels on machine for evenness and burrs.

7. After replacing doors, check for proper operation by raising and lowering with cantilever.

PROBLEM: One side of door higher than other and does not close completely.

SOLUTION: 1. Straighten cantilever arm.

2. This can sometimes be accomplished while arm is on machine by forcing down on the arm connected to the
high door while the other side of the cantilever is pulled up.

3. If step two cannot be accomplished on machine, cantilever will have to be removed and straightened.

WATER LEVEL CONTROL(ELS)

(FOR RINSE TANK) P/N 0205000

FUNCTION

The Water Level Control device utilized on power rinse (PRB) models only, automatically maintains
the water level in the rinse tank. The rinse tank water level control is energized by the master switch. The
control is designed to sense when the proper water level is maintained. At this time. the relay in the clear
plastic case will activate, opening the normally closed circuit to the solenoid, which stops the water flow
to the rinse tank.

When water is removed from the tank by the rinse pump, the sensing probe will alert the water level
control by signal to deactivate and return the contact points on relay (in clear plastic case) to the normally
closed position, allowing power to be reapplied to the solenoid valve. Water will again flow into rinse tank
until proper level is reached and maintained.

CHECKOUT
NOTE: ALL ELECTRICAL CHECKS SHOULD BE MADE BY QUALIFIED SERVICE PERSONNEL
OR ELECTRICIAN.

If one of the following problems exist, this control should be checked out as shown below:

1. Water to rinse tank runs continually with the master switch on.

2. Water does not flow into rinse tank when required.

PROCEED WITH CHECKOUTS:

1. Remove power source to machine by moving breaker to "off" position.

2. Remove 4 screws holding control pane! to control box and fasten to control box on right side,
using 2 screws with backside of panel outward.

3. Locate the water level control for the rinse tank circuit (sketch below). Remove, mark. and insulate
for easy replacement wires going to letters C and H on control.

4. Reapply power and turn on master switch.

5. With insulated wired, connect jumper wire between terminals C and H (24 Volt system).

6. If relay (inside clear plastic case marked "X" on drawing below) operates, then the water level
control action can be deemed operational, and other causes should be explored (see
troubleshooting section).

7. If relay doesn't operate, then check relay coil continuity. Replace relay or complete control, as
necessary.

8. Remove power source once again and replace wires removed in (3) to original terminals or new
control, if replacement was made.

27

WATER LEVEL CONTROL (ELS)

(INITIAL FILL AND WASH-HEAT CIRCUIT) P/N 0205000

FUNCTION

This control is activated when the master switch is turned on. The primary function is to automatically
control the proper initial filling of the wash tank, then to activate the wash and rinse tank heat circuit It will
also provide cutoff of the wash and rinse heat circuit, should the water be accidentally drained from the
machine (with the master switch still on). The master switch should be turned off before draining.

This water level control is used in conjunction with two probes (sensors), master switch, fill

switch, rinse relay, thermostat(s). heat relay(s), solenoid or rinse motor.

When the master switch is turned on, the normally closed circuit in the plug-in relay is energized. As the
fill switch is pushed upward and released, the rinse relay contacts close, and the solenoid (or rinse pump on
PRB model) opens and water flows into wash tub. As the water rises in the wash tub, it will cover first the
lower probe (directly above wash element) then reach the upper probe. At this time, the plug-in relay coil will
be activated and open the normally closed contacts, de-energizing the solenoid (or rinse pump).
Simultaneously, the contacts will close on the normally open circuit, energizing the wash-rinse heat circuit.
(Checkout and information concerning that part of the circuit are in the wash heater system or rinse heater
system instruction page of this manual.)

If the water should be drained from the machine while the master switch is still on, the lower probe
will sense the lack of water and de-energize the plug-in relay, which will de-energize the wash-rinse heat
circuit. DO NOT DEPEND ON THIS - - always turn master switch off before draining.

SYMPTOMS OF LEVEL CONTROL FAILURE:

1. Fill does not take place unless rinse switch is held upward until full.

2. Initial fill does not stop when it reaches overflow, but continues.

3. Wash-rinse heat circuit does not activate.

4. Wash heater remains on (if wash water accidentally emptied with master switch on.)

PROCEED WITH CHECKOUT:

1. Remove power to machine by turning customer circuit breaker to its "off" position. Turn machine
circuit breaker, located on right side on control box. to "off".

2. Remove 4 screws holding control panel on control box. Remove panel and attach to one side of
control box with 2 screws, with back side facing toward you.

3. Locate initial fill and wash-heat circuit water level control board and disconnect wires going to
terminals marked C, H, and L. Mark and insulate wires for replacement.

28

4. Be sure wash tank is empty and master switch and heat switch are off. Carefully reapply power to machine.
Begin by turning master switch on. With an insulated jumper wire, touch jumper between terminals C & H; relay
in clear plastic cube should activate as wire is touched to terminals. Observe relay contacts - - they should pull
in. If they do, remove wire and they should return to original position. Repeat several times to verify action.
Reconnect wires removed.

5. If relay operates, the control can be deemed operational and other causes should be explored. EXAMPLES: 1.
Loose or broken wire to probe or ground (green wire).

2. Dirty probe(s).

3. Solenoid faulty (see instruction page concerning solenoid).

4. Thermostat faulty or needs adjustment (see instruction page concerning thermostat).

5. Wash element faulty (see instruction page concerning wash-heat checkout).

6. If relay does not operate, check voltage being applied to LI - L2 marked on control. It should be 208-230V.
Replace control, if necessary.

7. In any case, always locate sensor (probes) inside wash tub and clean off all deposits (instruct customer; this
should be at least a weekly project).

8. Remove power to machine and replace panel and any wires that were not replaced previously.
