INSTALLATION
This section covers unpacking and inspection, selecting location, installing unit, preparing for operation, and op-
eration.
A. REMOVE ICEMAKER FROM CARTON
1. Keep unit in the upright position, remove carton and pallet from unit and inspect unit for damage. Upon in-
spection 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 HOOK UP
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 recom-
mended.
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.
2. Condenser Outlet— is a 3/8?FPT located on the rear panel.
NOTE: Unit must be installed per local plumbing code. BOCA.

8
638085278
F. ELECTRICAL SUPPLY
1. Power Access— is provided with a 7/8?dia. knockout hole in the rear panel. Route incoming power in
conduit, through rear panel to icemaker electrical control box. Make connections to wires provided in the
control box and ground lug/screw.
2. Fused Line— should be checked and sized according to electrical rating shown on unit nameplate.
G. AUGER ENGAGEMENT
Be certain that auger is fully engaged to lower drive and extruding head is fully engaged into evaporator.
H. BIN CONTROL
1. Remove tape holding control to white ice chute and also remove control bracket mounting screw located in
base of unit behind electrical box. (Screw will be used later to fasten bin control bracket to base of unit).
2. Slide control and bracket down chute to base of unit. very carefully guide control and bracket through 1/2?
hole in front of ice chute. Use CAUTION to be sure control goes into bin, not between base of unit and
bin top.
3. Check location of bin control, it should be directly under ice chute at a 45_angle. With control in place use
mounting screw that was removed in step 1 to secure bracket to base. See Figure 4
FIGURE 4. BIN CONTROL
INITIAL START UP, CHECKS AND ADJUSTMENT INSTRUCTIONS
NOTE: Do not start unit before completing installation steps on pages 7 and 9.
Turn on water supply (if unit is water cooled turn water on to condenser also) turn on main power switch (lo-
cated on top of electrical box), and make the following system checks:
NOTE: If unit will not start be sure water reservoir is full. Low water safety control must be properly
adjusted to start and shut down unit. If water level drops below bottom of reservoir, unit must shut
down. Adjustment is made by moving magnet up or down.
Water Level— If necessary adjust float by bending float arm up or down as needed, push float assembly down
until unit stops running. Release float and unit will restart. Keep water in reservoir at level line while unit is in
operation. See Figure 5
Low Water Safety Control— Adjust magnet by bending magnet arm as needed to shut unit down if water level
drops below bottom of reservoir.
Bin Control— Place ice around probe, unit should shut down in one minute. Remove ice from around probe,
unit should start in two minutes.

9638085278
NOTE: For altitudes over 1000 feet above sea level, adjust range screw (behind end cover). Half turn
max. raises setting 4_F approx.
FIGURE 5. ICEMAKER FLOAT ASSEMBLY
Water modulating valve (water cooled units only)— Opening point of condenser water modulating valve
should be set to maintain proper operating pressure in the refrigeration system high side. (see chart on page
16). Closing point of valve should be set low enough to close valve during compressor stand by periods. To
raise, turn counterclockwise, to lower turn clockwise.
NOTE: If any of these checks or adjustments cannot be achieved, refer to Troubleshooting Section of
this manual or call for factory assistance at 1--800--Service.

11. Fill icemaker with sanitizer by slowly pouring solution into water feed reservoir until full. Solution will drain
through overflow tube. Do not run machine. Allow to air dry.
12. If icemaker is used in conjunction with ice dispenser or storage bin, follow manufacturer’s recommended
cleaning instructions at this time.
MAINTENANCE
Preventive maintenance can increase the trouble free life of your icemaker. Many authorized service agencies
offer service contracts for your icemaker. Contact your local distributor for further information.
MONTHLY
1. Clean the condenser. Use a brush, vacuum cleaner or blow from inside with air or CO2gas.
2. Inspect water feed reservoir at lease once a month until a definite pattern for cleaning and sanitizing has
been established.
QUARTERLY
This is the maximum period of time between cleaning and sanitizing the icemaker. In addition to recommended
monthly procedure, and if a more frequent cleaning and sanitizing pattern has not been established, unit must
be cleaned and sanitized.

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 water level control will not shut off and seal at level as indicated, be sure inlet pressure does not exceed rec-
ommended factory operating range.
Under ordinary circumstances adjustment should not be necessary providing it was properly adjusted when unit
was installed or relocated. If, however, the control becomes inoperative, repair or replace. See Start-Up Adjust-
ment, page 9.
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 inter-
nal 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 wing nut holding water control to its mounting bracket. Control can be removed by lifting straight
up.
TO REPLACE WATER LEVEL SAFETY SWITCH
1. Shut off main power switch or unplug the ice dispenser from electrical outlet.
2. Unplug molex connector connecting switch to electrical box.
3. Remove the 2 screws anchoring the water level safety switch to the bottom of the water level control
mounting bracket.

REFRIGERATION SYSTEM ADJUSTMENTS
A complete understanding of the icemaker and hermetic refrigeration system is necessary before any adjust-
ments are made. The refrigeration technician must use high and low side pressure readings, water and air tem-
peratures, 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 evapo-
rator, a clean condenser, unit is properly ventilated, and system is properly charged and free from any restric-
tions. Also be sure compressor is operating properly.
Second, take reservoir water temperature and air temperature from condenser inlet and determine at what pres-
sure 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 question-
able 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 be-
fore troubleshooting expansion valve.
