KEY THINGS TO KNOW / DO
SThis is a batch harvest system.
SThe sealant should be added before the unit is placed on the dispenser or bin. Always seal the ice
maker to the bin (with a gasket or food grade sealant). Sealing prevents melted ice from running out
of the joint between the ice machines!
SChoose the proper condenser for the application:
Air – with sufficient clean air circulation.
Water – high ambient temperature or dusty environment, restricted air flow, or where extra BTUs are
un–wanted.
Remote – when heat or noise are a problem!
SAlways refer to serial plate for electrical power requirements and refrigeration charge and type of
refrigerant!
NOTE: Note serial plate locations. Lower left–hand corner of cabinet, inside the unit on the bulk-
head between the evaporator and the compressor.
SAlways use proper size and type of water conditioning equipment (filter, chlorine, etc.)!
SDo NOT use softened or reverse osmosis water!
SThere is a manual reset high pressure cut out on the 500 series units.
SInstallation of a bin thermostat control is required in some installations, such as ice drink dispensers
or ice drink unit!
SBin stat is available to lower ice level! Part No. 630000408.
NOTE: If there is a very large slab of ice on the evaporator you will need to push the manual har-
vest button to remove it.

INSTALLATION INSTRUCTIONS
Installation and start up of the equipment should be performed by the distributor or the dealer’s profes-
sional 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 6I(15.24 cm.) clearance
at the rear and right side 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_) 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.
EQUIPMENT SET-UP
The following steps refer to the set-up of the ice bin and the cuber:
1. Remove the bin from its carton, place it on its back and install the legs and drain flange (if applica-
ble) into the bottom of the bin. Bins must be installed on legs or sealed to the floor with RTV-732
sealant.
2. Set the bin up on its legs. Place the bin in its final location and level it with the adjustable feet in the
legs. (See Figure 2).
NOTE: It is critical that the unit be level to ensure adequate ice production.
3. Unpack the cuber from its carton, and set in place on the bin and adjust as required. Leave all pan-
els on the cuber until it is set in place on the dispenser or bin.
4. Remove all internal packing from the cuber. Remove tape from evaporator curtain.

LEG INTO BASE
FIGURE 2
NOTE: Bin adapter and condenser air baffles may be required in certain installations.

Xtreme Ice Training Manual
TP00952
October 17, 2005 7
DISPENSER INSTALLATION
1. Order the proper cuber/dispenser adaptor kit. This package include gasket material, a hold-down
bracket, and bin stat kit (contact service provider for more information).
2. RTV applications (See Figure 3). If the ice bin is full, new ice will not be able to drop. Instead it
blocks the evaporator curtain open and no additional ice is made. This new ice may start to melt and
the resulting liquid can leak out of the joint between the ice maker and bin. To prevent this problem,
seal the joint with food grade silicon sealant.

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 wa-
ter-cooled. 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 than 20 PSI (1.37 BAR), nor should it exceed 80 PSI (5.52
BAR).
NOTE: Water filters larger than 5 microns do not give proper protection.
NOTE: Bin and cuber drain lines must never be connected together and must be vented.
NOTE: Always flush inlet water lines 1–2 minutes before connecting to Ice Maker.
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. Strain relief connectors must be used at the junction box of the control box and the cuber.
4. Cuber must be grounded by the control box ground screw or other method for intentional safety
grounding that meets code requirements.
5. A manual disconnect in a convenient location to the cuber must be installed.
NOTE: See Remote Condensers, Install Instructions.
NOTE: All HP-62 (R404A) ice machines have a voltage range of –5%, +10% from the serial plate
rating.
INSTALLATION CHECK POINTS
1. Has bin and cuber been leveled and sanitized?
2. Does electrical and plumbing meet code requirements?
3. If water-cooled, are inlet and drain connections to condenser correct?
4. Are drain lines separate and vented?
5. Is there a 6Iclearance on the right and back side for proper air circulation?
6. Does the water curtain move freely? Does the inlet solenoid valve shut off incoming water to
the water pan?
7. Has the unit been properly sealed to the bin or dispenser?
NOTE: A 6” top clearance will improve service accessibility.
START UP AND CHECK OUT
Start Up Sequence
1. Check all connections.
2. Turn on the main power switch. The red LED will flash 6 times then remain on for 4 seconds.
3. The unit will go through a 45 second hot gas defrost to remove any ice that might be on the
evaporator.
4. There will be approximately a (45) second evaporator pre–chill, then the water pump will start,
and the freeze cycle begins.

START UP SEQUENCE (PRIMARY)
1. Check all connections.
2. Water pan must be empty at the start of the initial fill cycle.
3. Turn on the main power switch, the red LED will flash 6 times then remains on for 4 seconds.
NOTE: If there is a very large slab of ice on the evaporator you will need to push the manual har-
vest button to remove it.
SECONDARY START UP
1. Compressor starts after ERROR LED extinguishes, and the green COMP LED turns on.
2. Compressor runs continuously after secondary start up sequence.
3. Hot gas valve opens for a 45 second period.
4. Green GAS LED is on when the hot gas valve opens.
5. After 45 seconds, the hot gas valve de–energizes.
NOTE: If there is a very large slab of ice on the evaporator you will need to push the manual har-
vest button to remove it.
6. Compressor starts then the unit will go through a 45 second hot gas defrost to remove any ice
that might be on the evaporator.
7. The water inlet solenoid makes its initial fill.
8. There will be approximately a (45) second evaporator pre chill, then the water pump will start,
and the freeze cycle begins.
DUMP CYCLE
1. The dump cycle can be changed by moving the setting on the dump cycle dip switches.
2. If both switches are off, the machine dumps water after each cycle. This is the factory set point.
3. If switch 1 is on and switch 2 is off, the machine dumps after every third harvest.
4. If switch 1 is off and switch 2 is on, the machine dumps after every seventh harvest.
WATER FILL CYCLE
1. The fill valve opens.
2. The green FILL LED is on when the fill valve energizes.
3. Once the water level reaches the maximum level the fill valve de–energizes.
NOTE: During the initial filling of the water pan, air is captured inside the pressure sensor pick
up. When the pressure inside the pressure sensor pick up rises to a predetermined value, the
pressure transducer shuts off the water fill valve and starts the prechill cycle then the freeze
cycle.
PRECHILL CYCLE (300’S, 500’S, 600’S, 800’S, 1000’S, AND 1200’S)
1. The water pump turns on 45 seconds into the cycle.
2. After another 45 seconds, the fill valve turns on and tops off the water level.
3. Once the water level reaches the maximum level the fill valve de–energizes.
4. During normal operation, as the water pan fills the D.C. voltage will range from .25 to 3.5 VDC at
center and left pins, on the J9 connector (See Figure 8).

Xtreme Ice Training Manual
TP00952
October 17, 2005 15
PRECHILL CYCLE (1400’S AND 1800’S)
1. After the water fill cycle is complete, the water pump turns on.
2. When the water temperature reaches 40_F, the pump turns off.
3. After one minute, the pump comes back on.
4. After another ten seconds, the fill valve opens.
5. Once the water level reaches the maximum level, the fill valve closes.
FIGURE 8
FREEZE CYCLE
1. Ten seconds after the fill valve turns off, the microprocessor records the water level.
2. Using the recorded high water level, the calibration level and the ice thickness level, the micropro-
cessor calculates a harvest level.
3. The microprocessor monitors the water level until it reaches the harvest level.
NOTE: There are two revisions of control boards that have a five minute timer built into the freeze
cycle. This timer prevents the unit from going into a defrost cycle until the compressor has been
running for a minimum of five minutes.
The control board revisions number are: 100592 CRN; 100795 CRN.
NOTE: As ice builds on the evaporator the water level in the water pan drops. This is called
batch harvesting.
HARVEST CYCLE
1. The hot gas solenoid opens, the dump solenoid opens, and the water pump remains running for 15
seconds.
2. The microprocessor monitors the proximity switches waiting for the circuit to open.
3. Once all of the proximity switch circuits have opened, the hot gas solenoid closes.
4. The microprocessor monitors the proximity switches to close.
5. Once all the proximity switch circuits close, the harvest cycle terminates.
NOTE: When the pressure inside, the pressure sensor pick up lowers to a predetermined value,
the pressure transducer starts the harvest cycle.
FAN CONTROL
1. Fan control operates when the hot gas solenoid is closed.
2. The fan turns off when the condenser temperature is below 88_F.
3. The fan turns on when the condenser temperature is above 100_F.
