INSTALLATION
This section covers unpacking and inspection, selecting location, installing unit, preparing for operation, and
operation.
A. REMOVE ICEMAKER FROM CARTON
1. Keep unit in the upright position, remove carton and pallet from unit and inspect unit for damage. Upon inspection
of unit, if any damage is found, file a claim with carrier immediately.
2. Locate startup card either on outside of container or on plastic liner. Fill in proper information and send one
copy to factory, and other copy to distributor. Postage is prepaid.
B. CABINET REMOVAL
1. Front Panel—Remove 4 screws and pull forward.
2. Top Panel—Remove screws and lift upward. 4 screws 500/700, 6 screws 1000.
3. Side Panel—Remove 4 screws and pull forward.
4. Back Panel—Should not be removed.
C. PREPARATION OF INSTALLATION SITE
1. The refrigeration system on air cooled units requires airflow, so a well ventilated area should be chosen. A minimum of 6 inches must be maintained, free of any obstructions, for air intake. A minimum of 4 inches clearance
is required for air exhaust.
2. The unit can be installed either on an ice storage bin or ice dispenser using the proper adapter kits. (Refer to
sales literature for information.) The install is kit provided with each icemaker and adapter kits will supply everything to locate unit correctly. In all cases the icemaker should be sealed all around the base with an NSF listed
sealant. (63804815B)
D. WATER INLET HOOKUP
1. Water Inlet—fitting is a 1/4 SAE male flare located at the rear of the unit. Connect water supply with a 1/4 SAE
flare nut and 1/4” copper or flexible tubing or larger.
2. Water Pressure—Unless otherwise specified, the unit is designed to operate on water pressures between 10
P.S.I. and 90 P.S.I. (NOTE: for pressures above 90 P.S.I. a regulator must be installed.)
3. Condenser Inlet Connections—Use a separate 3/8” copper line or larger water line. Connect to 3/8 FPT fitting on water modulating valve.
4. Filter/Conditioners are recommended on supply lines to icemakers. Never run the water supply to water cooled
condenser through filter/conditioner, it uses up the cartridge unnecessarily and a saturated cartridge can
starve the icemaker causing premature component damage. Separate water supplies are recommended.
NOTE: Unit must be installed per local plumbing code BOCA.
E. DRAIN CONNECTION
1. Overflow Line—is a 3/8” I.D. flexible tube located at the rear of the unit. Extend this line to proper drain.

WATER LEVEL CONTROL
HOW WATER LEVEL CONTROL WORKS
When water is introduced through the inlet fitting the float rises. the float pushes against a lever which in turn forces
the poppet assembly against the inlet fitting valve seat which seals the water off. See Figure 5. Before the water inlet
is sealed the safety switch is operated. In the event of a water failure the float would drop down and operate the safety
switch to shut off the machine.
If the water level control does not shut off and seal at level, as indicated, be sure inlet pressure does not exceed
recommended factory operating range.
Under ordinary circumstances adjustment should not be necessary providing it was properly adjusted when the unit
was installed or relocated. If however, the control becomes inoperative, repair or replace it. See Start-Up Adjustment,
page 7.
PURPOSE
1. To automatically maintain proper water level in the evaporator when unit is running and making ice.
2. A safety switch is operated in the event of an interruption in water supply. The switch shuts off the electrical
power to the icemaker and its refrigeration system. Switch will reset as soon as cause of water failure has been
corrected and proper water level in icemaker has again been reached.
3. The transparent bowl not only provides a visible check of water level, but also is a good guide to the internal
conditions which exist within the icemaker assembly itself. (See Cleaning Procedure.)
TO REPLACE WATER LEVEL CONTROL
1. Shut off the water supply, Shut off the main power switch or unplug the ice dispenser from electrical outlet.
2. Remove the flexible tubing from bottom of water level control and drain water from water level control and evaporator.
3. Remove flexible tubing at bottom of water level bowl connected to the overflow.
4. Hold water inlet fitting with proper tool to prevent it from rotating when disconnecting the water inlet.
5. Remove the wing nut holding the water control to its mounting bracket. Control can be removed by lifting
straight up.
TO REPLACE WATER LEVEL SAFETY SWITCH
1. Shut off the main power switch or unplug the ice dispenser from electrical outlet.
2. Unplug molex connector connecting switch to electrical box.
3. Remove the two (2) screws anchoring the water level safety switch to the bottom of the water level control
mounting bracket.

NOTE: Thermostatic Expansion valve is non-adjustable on all models.
REFRIGERATION SYSTEM ADJUSTMENTS
A complete understanding of the icemaker and hermetic refrigeration system is necessary before any adjustments
are made. The refrigeration technician must use high and low side pressure readings, water and air temperatures,
plus general conditions of cleanliness to assess the refrigeration system status when making any adjustments.
All icemaker products are tested and adjusted at the factory prior to shipment where the ambient temperature ranges
from 65° to 90° F, depending on the season of the year.
Whenever a new icemaker product is initially installed and started-up, it is imperative that the start-up operation make
the following checks and/or readjustments for local conditions.
EXPANSION VALVE
You will find a thermostatic expansion valve on icemakers, which is used to control the amount of refrigerant flowing
through the evaporator. Improperly installed or defective expansion valves may cause low production, soft ice,
squeaking from evaporator and excessive load inside evaporator.
By using general refrigeration system troubleshooting along with the pressure charts you can easily determine
whether or not the expansion valve is working properly.
ADJUSTMENT AND TROUBLESHOOTING
When troubleshooting the expansion valve you must first be sure you have adequate water flowing into evaporator, a
clean condenser, unit is properly ventilated, and system is properly charged and free from any restrictions. Also be
sure compressor is operating properly.
Second, take reservoir water temperature and air temperature from condenser inlet and determine at what pressure
unit should be running. Machines are equipped with thermostatic valves, there is NO adjustment. If correct pressure
cannot be obtained, first be sure system has time to stabilize 10-15 minutes. Second, be sure sensing bulb is located
at 12:00 position on outlet side of evaporator about 3-4 inches away from evaporator and be sure to insulate well and
clamp tightly to tubing. If system pressures are still not adequate, take a second water and air temperature reading
and go over other parts of system for possible problems. If proper charge is questionable evacuate and recharge to
nameplate and leak check. If valve still malfunctions replace valve.
When replacing valve be sure to bleed refrigerant gas from low side port so as not to lose refrigerant oil. Use general
refrigerant system practices when replacing and recharging unit. After new valve is in place, go through previous
monitored adjustments and troubleshooting to be sure valve is functioning properly.
NOTE: Units with thermostatic expansion valve-valve is located on bottom refrigerant line.
Sensing bulb is located on top refrigerant line. On water cooled units adjust condenser modulating
valve before troubleshooting expansion valve.

Continuous Flow Icemaker Installation and Service Manual
! CAUTION:
Very high discharge pressure is present in system. Quick disconnects on your gauges will minimize danger and loss
of refrigerant. Comply with federal regulations for reclaiming refrigerant.
CONDENSER MODULATING VALVE
The reason for using a water modulating valve is to supply the correct amount of water to the condenser. and to
maintain a proper operating pressure to refrigeration system high side.
The flow of water through the valve is increased as the high side pressure rises and is decreased as high side
pressure lowers.
To calibrate the amount of water flow with the refrigeration system high side pressure, turn adjustment screw located
on end of valve opposite of bellows. See Figure 14. Turn screw counterclockwise to raise opening point or clockwise
to lower opening point. Opening point of valve should be set to maintain proper operating pressure in refrigeration
system high side. Refer to Pressure Chart on page 15. Closing point of valve should be set low enough to close valve
during compressor stand-by periods.
NOTE: Cold water will absorb heat faster than warm water. The water flow will therefore
automatically increase as inlet temperature increases.

CONDENSER MODULATING VALVE REMOVAL
! WARNING:
Disconnect power to the unit before servicing. Follow all lock out/tag out procedures established by the user. Verify all
power is off to the unit before performing any work.
Failure to comply could result in serious injury, death or damage to the equipment.
1. Shut off water supply to condenser and evacuate refrigerant from system.
2. Remove inlet water line from Condenser Modulating Valve. Also remove tube from high side refrigerant line.
3. Remove Condenser Modulating Valve and bracket from unit.
4. Remove valve from bracket.
5. Replace Condenser Modulating Valve by reversing Steps 2 thru 4. Then pull system into vacuum.
6. Charge unit with proper amount of refrigeration.
7. Turn power and water on to unit.
8. With unit running, adjust modulating valve to proper setting.
9. Go through a complete system check.
BIN CONTROL
The type of bin control used on all WCC Models is thermostatically controlled. The switch itself is inside the electrical
box and can be serviced from the front of the unit. The cap tube bulb is located directly under the ice chute.
To test the switch, disconnect power to the unit and remove one wire from the switch. Connect both leads of the
ohmmeter to the Bin Control Switch terminals. With the control bulb at room temperature ohmmeter should read
“Closed Circuit”. Refer to Figure 15.
Cover the control bulb with ice. Within one minute the switch should “click” and the ohmmeter should read an “Open
Circuit.”
The Bin control is in series electrically with the coil on the antifreeze relay along with the low water safety. If the unit is
water cooled, the condenser high pressure cut out is also in series.
The Control Switch is held in place inside the electrical box by two screws. Control bulb is positioned under the ice
chute and can be replaced by removing the screw that holds the bracket to the base of the unit. With the control and
bracket removed, slip the bulb off the end of the bracket. The most important thing to remember when replacing the
probe is to be careful not to cut or kink it and be sure the sensor bulb is located in a position to shut the unit down
before ice reaches the ice chute.
This icemaker is also equipped with a safety ice level sensor. This sensor control is located on the dispense tray
cover. This switch is also in series with the anti-freeze relay and other safety circuitry.

GEAR MOTOR
The gear motor is equipped with a start relay and a manual reset overload.
When current is applied, the relay energizes and completes the circuit to the start winding. The motor reaches a
predetermined speed and the relay drops out, disconnecting the start winding. The run winding remains in the circuit
as long as current is applied.
The purpose of the overload is to automatically shut off the motor in the event of a mechanical bind of the
transmission, an overload condition within the evaporator or an electrical malfunction. It does this by sensing
amperage draw. If the motor stalls the start relay would energize and stay energized. The amperage would surge 5 to
6 times greater than the normal draw. In this event the overload would shut off the transmission in 4 to 8 seconds.
If the motor is subjected to an abnormal load, but does not reach a stall condition, the overload will react, but over a
greater period of time. The reaction time depends upon the amperage to which it is subjected.
The overload, through the safety circuit, also shuts off the compressor.

Remedy
Basically the compressor problems can be narrowed down to three areas of checkout.
A. No voltage to the compressor
A. Check circuit
The Compressor will not run
terminals.
The compressor starts but trips
repeatedly on the overload protector
The compressor runs but does not
refrigerate

voltage
See electrical checkout
instructions
Check for proper fan operation and
clean condenser
Check the compressor suction and
discharge pressures
Voltage should be within 10% of
the rated nameplate voltage
It should never exceed 120% of the
rated nameplate amperage. See
electrical checkout instructions.
Check the compressor suctions
and discharge pressures. See
chart on page 15.
