INSTALLATION
This section covers unpacking and inspection, selecting location, installing Unit, preparing for operation, and
operation. Installation and start-up of the equipment should be performed by the distributor or the dealer’s
professional staff.
LOCATION OF EQUIPMENT
For maximum performance the location should be away from heat sources such as ovens, direct sunlight, hot
air discharge, etc.
To reduce cost of maintenance and loss of efficiency, avoid placing air-cooled equipment in areas where grease,
flour and other airborne contaminants are present. Allow a minimum of 6” (15.24 cm) clearance at the front for
proper air circulation. Restricted air circulation will affect the efficiency and required maintenance of the product.
IMPORTANT: Never operate your equipment in room temperature below 50_F (10 _C) OR ABOVE
100_F(38_C). Should the location of your product ever be exposed to freezing temperatures, it must be
shut down and winterized.

PLUMBING CONNECTIONS
1. All plumbing lines and connections must conform to local and national plumbing codes.
2. Line shut-off valves must be located in supply water lines for cuber and condenser if product is watercooled. Water supply to water-cooled condenser must include a stand-pipe to prevent “water hammer”.
3. Should your local water supply quality require the installation of a water filter system, consult your local distributor or dealer for proper size required.
4. Water supply pressure must not be lower the 20 PSI (1.37 BAR), nor should it exceed 120 PSI (8.16
BAR).
IMPORTANT: water filters larger than 5 microns do not give proper protection. Water pressures above
80 PSI (5.44 BAR) will destroy the filter.

ELECTRICAL
1. All wiring and connections must conform to national and local electrical codes.
2. Wire size and circuit protection must conform to specifications and cuber must be on a separate electrical
circuit.
3. Cuber must be grounded for the safety requirements.
4. A manual disconnect in a convenient location to the cuber must be installed.
INSTALLATION CHECK POINTS.
IMPORTANT: For the Ice Cube Machine to operate properly, the front and back panels must be in place
on the machine. When the Ice Cube Machine is operated without the panels in place, airflow across
the condenser coils is affected, causing pressure variations. These pressure variations can result in
low or a failed ice harvest.
1. Has bin and cuber been leveled and sanitized?
2. Does electrical and plumbing meet code requirements?
3. Check correct operation water level in the water pan.
4. Are drain lines separate and vented?
5. Is there 6” clearance in the front of the machine for proper air circulation?
6. Does the ice harvest switch move freely, and does the float valve shut off incoming water to water pan?
7. Vigorously rub the stainless steel water plate(s), on top of the evaporator(s), with scotch-brite pad to remove any oxidation and improve the ability of the water to properly track across plain.

START-UP AND CHECK OUT
1. Turn the cuber’s power switch to the clean (pump only) position. The water pump only should be operational. Check for an even, steady flow of water over the evaporator top extrusion and down over evaporator
surface. Check that all ports of the water distribution tube are open for even water discharge. The water
pan should refill and the float should stop the incoming water supply.
2. Place the cuber’s power switch in ON position. After a 2 second delay the compressor will start. The condenser fan will operate when the condenser sensor signals the circuit board that its temperature is 100
(38_ C). The water pump will operate when the evaporator cools to 25_F (3.9_ C). Depress the manual
harvest switch located on the circuit board. The fan motor will stop and the water dump valve will open. in
3 seconds the hot gas solenoid will open and 15 seconds after depressing the manual harvest switch, the
water pump will stop and the dump valve will close terminating the dump cycle.
3. Hold the ice harvest switch open for a maximum of 30 seconds; the product should shut down. Release the
ice harvest switch. When the switch closes, there will be a 2 second delay, and the compressor will start
and the start-up process should begin for the next ice making mode.
4. If all product operation are as stated, allow product to operate and product one slab of ice, then discard the
ice. Allow the product to continue operation to fill the storage bin.

ADJUSTING BRIDGE THICKNESS
TOP ROW
3/8’ - 5/8”
DIMPLE
CENTER
1/8” BRIDGE
For optimum ice production and maximum cube separation, the ice connecting the individual
cubes should be a minimum of 1/8” (.32 cm) thick at the center area of the ice waffle.
BRIDGE 1/8” (0.32 CM)
It is normal for the Ice Bridge to be slightly thicker at the bottom and taper off in a slight wedge
pattern at the top. The top row of cubes must have a complete pattern of ice on all four sides
and the back wall.

BRIDGE
FIGURE 7. CUBE SEPARATION
REMEMBER: When you operate the product with the panels off during testing the additional heat at the top of
the evaporator will cause thinner ice at the top than when the panels are in place.
Should a different thickness of the bridge be desired, it will be required to adjust the ice thickness “POT”, located on the circuit board, as follows:
1. Thinner Bridge - Turn the ice thickness “pot” adjustment screw Ø CW one full turn.. Allow two cycles be-
fore determining if additional adjustments are required.
2. Thicker Bridge - turn the ice thickness “pot” adjustment screw Ù CCW on full turn. Allow two cycles before
determining if additional adjustments are required.
NOTE: Never judge the thickness of the ice from the first batch of ice produced - the first cycle is a
balance cycle. Always wait for the second cycle before making and adjustments.
HARVEST CONTROL
An ice harvest switch bar is used to control the harvest cycle. It is operated by the movement of the ice from
evaporator. The momentary opening of the ice harvest switch terminates the ice machine’s harvest cycle.. As
the ice harvest bar swings closed, the ice machine returns into the freezing cycle.
FULL BIN CONTROL
A bin thermostat is provided to control the level of the ice in the storage bin. When the storage bin is full, the bin
thermostat tube equipped inside the storage bin will sense a low temperature which causes the bin thermostat
to switch to it “close” position. The ice machine will complete the cycle and shut off.
The ice machine remains off until sufficient ice is removed from the storage bin allowing the bin thermostat tube
to warm up. As the bin thermostat tube senses a warm temperature which causes the bin thermostat to switch
back to its “open” position, the ice machine starts to make ice.
The setting of bin thermostat can be adjusted by turning the dial on the top of thermostat to”CW” to cold position
or to “CCW” to warm position. In the mid-range position the bin thermostat will close at about 42_F.
