INSTALLATION INSTRUCTIONS
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 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.
Baffle Installation
NOTE: The baffle is only used on the 1030, 1230, 1444, and 1844.
The baffle must be used when the right hand side of the icemaker is installed in a corner. This will prevent dis­charge air from recirculating to the condenser.
1. Loosen three screws, as shown in Fig. 1.
2. Install baffle, as shown in Fig. 1. with paper towards the front of the unit.
3. Tighten the three screws.

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 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.
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 panels 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.

DISPENSER INSTALLATION
1. The proper cuber/dispenser installation package should be ordered. This package will include gasket mate­rial, and hold-down bracket, and bin stat.
2. RTV applications (See Fig. 2 above). 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.
3. Install bin thermostat (Part Number 631500074).

Note: Leave all panels on the cuber until it is in place on the bin.
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 than 20 PSI (1.37 BAR), nor should it exceed 80 PSI (5.516 BAR).
NOTE: Water filters larger then 5 microns do not give proper protection. Water pressures above 80
PSI (5.516 BAR) will destroy the filter.
DRAIN LINES: 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 junctions 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 Install Instructions in the Xtreme Service and Training Manual (TP00952).
NOTE: All HP-62 (R404A) ice machines have a voltage range of –5%, +10% from the serial plate rating.
INSTALLATION CHECK POINTS
1.
2. Does electrical and plumbing meet code requirements?
3. If water-cooled, are inlet and drain connections to condenser correct to prevent “water hammer”?
4.
5. Is there 6I clearance on all sides and top for proper air circulation?
6.
7.
NOTE: A 6” top clearance will improve service accessibility.
Has bin and cuber been leveled and sanitized?
Are drain lines separate and vented?
Does the water curtain move freely, and does the inlet solenoid valve shut off incoming water to the water pan?
Has the unit been properly sealed to the bin or dispenser?
START UP SEQUENCE
1.
2.
3. The unit will go through a 45 second hot gas defrost to remove any ice on the evaporator.
NOTE: If there is a very large slab of ice on the evaporator you will need to push the manual harvest button to remove it.
4. If the water pan is empty, the unit will go through a fill cycle.
5.
Check all connections.
Turn on the main power switch, the red LED will flash (6) times then be on steady for (4) seconds.
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. Turn on the main power switch, the red LED will flash (6) times, then be on steady 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.
NOTE: If there is a very large slab of ice on the evaporator you will need to push the manual harvest button to remove it.
4. If the water pan is empty, the unit will go through a fill cycle.
5. There will be approximately a (45) second evaporator pre chill, then the water pump will start, and the freeze cycle begins.
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 harvest button to remove it.
DUMP CYCLE
1. Dump valve opens.
2. Green DUMP LED is on when the dump valve energizes.
3. If the water level is not at the high level the fill valve opens.
4. The green FILL LED is on when the fill valve energizes.
5. If the water level is below the minimum level the water pump remains off.
6. Once the water is a above the minimum level the water pump turns on.
7. The green PUMP LED is on when the water pump is on.
8. After a 15 second flush cycle the fill valve de–energizes.
9. The water pump turns on to drop the water level to the minimum level.
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 pre chill cycle then the freeze cycle.
PRE CHILL 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.
3. Once the water level reaches the maximum level the fill valve de–energizes.
PRE CHILL 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 degrees 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.

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 microprocessor calculates a harvest level.
3. The microprocessor monitors the water level until it reaches the harvest level.
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.
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.
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 an switch 2 is off, the machine dumps after every third harvest.
4. If switch 1 is off an switch 2 is on, the machine dumps after every seventh harvest.
5. Once the water reaches the minimum level, the dump valve de–energizes and the pump turns off.
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.
ADJUSTING BRIDGE THICKNESS
For optimum ice production and maximum cube separation, the ice connecting the individual cubes should be a minimum of 1/8I (.32cm) thick.
FIG. 7
BRIDGE 1/8I (0.32 cm)
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 C.W. one full turn. Allow two cycles before determining if additional adjustments are required.
2. Thicker Bridge – turn the ice thickness “pot” adjusting screw C.C.W. one 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 the ice produced – the first cycle is a balance cycle. Always wait for the second cycle before making any adjustments.
TOTAL ICE CAPACITY
Ice capacity of any ice maker is affected by many operating conditions, such as water and air temperature and location factors. Please review the capacity tables in this manual for average 24-hour capacity under various conditions.
NOTE: All printed capacity ratings are 10% except 50 HZ units. These products have 12% increase in cycle time and capacity decrease of approximately 17%.

ICE PRODUCTION CHECK
If air cooled, take air temperature at the intake of the condenser, 2I from the condenser fins, and Incoming wa­ter temperature at the outlet of the “fill” valve.*
Cycle time (CT) = freeze time plus harvest time, in minutes and seconds. 1440 divided by CT = number of cycles per 24 hours.
Measure weight of ice from one cycle in pounds and fractions of a pound.
EXAMPLE: Weight/cycle x cycles/day = total production/24 hrs. Compare to the production tables.
* If water cooled, be certain water regulator valve is set to maintain 260 - 271 PSI head pressure, or set con­denser outlet temperature to 108_F – 111_F
LED INDICATORS
The LEDs are board circuit indicators. If the LED in the functional board circuit is complete, check component. Example: Contactor does not energize and LED is “ON”, board circuit is OK. Check contactor, coil, leads, &

MAINTENANCE
SEMI-ANNUAL MAINTENANCE
1. GENERAL ICE MACHINE INSPECTION
2. CLEANING THE EXTERIOR
3. CLEANING THE CONDENSER – AIR-COOLED WATER-COOLED
4. INTERIOR CLEANING – CLEANING PROCEDURES SANITIZING PROCEDURES
GENERAL ICE MACHINE INSPECTION
S Check all water fittings and tubes for leaks. Also, make sure the refrigeration tubing is not rubbing or vibrat-
ing against other tubing panels, etc.
S Do not stack anything (boxes, etc.) on or around the ice machine. S Do not cover the ice machine while it is operating. There must be adequate air flow through and around the
ice machine to ensure long component life and adequate ice production.
CLEANING THE EXTERIOR
1. Clean the area around the ice machine as often as necessary to maintain cleanliness and efficient opera­tion.
2. Sponge dust and dirt off the outside of the ice machine with mild soap and water. Wipe dry with a soft clean cloth.
WARNING: Stainless steel panels should be cleaned with mild soap or a commercial stainless steel cleaner. Do not use cleaners containing bleaching agents: they usually
contain chlorine which stains stainless steel. Heavy stains should be removed with stainless steel wool. Never use plain steel wool or abrasive pads because they will scratch the panel and cause rusting.
CLEANING THE CONDENSER
CAUTION: Condenser fins are sharp. Use care when cleaning them.
Disconnect electric power to the ice machine at the electric service switch box before cleaning condenser!
Air–Cooled Condenser
A dirty condenser restricts airflow which results in excessively high operating temperatures. High operating tem­peratures reduce ice production and shorten component life. Clean the condenser at least every six months.
CAUTION: Condenser fins are sharp. Use care when cleaning them.
December 22, 2005
15
630460146OPR
1. Clean the outside of the condenser with a soft brush or vacuum with a brush attachment. Brush or wash condenser from top to bottom, not from side to side. Be careful not to bend the fins. Shine a flashlight through the condenser to check for dirt between the fins.
2. If further cleaning is required, blow compressed air through the condenser from the inside. Take care not to bend the fan blades. Shine a flashlight through the condenser to check that all the dirt is removed.
Any bent condenser fins must be straightened with a fin comb. Contact your local service agent to do this service.
Water-Cooled Condenser (and regulating valve)
The water-cooled condenser and water regulating valve may require cleaning due to scale build-up.
Low ice production, high water consumption, and high operating temperatures and pressures all may be symp­toms of restrictions in the condenser water circuit.
The cleaning procedures require special pumps and cleaning solutions and, therefore, should be performed by qualified maintenance or service personnel.
CLEANING THE INTERIOR
Approved ice machine cleaners by brand names:
S Calgon Nickel Safe (green color only)
NOTE: Failure to use approved products will void the warranty.
CAUTION: Ice machine cleaners are acidic-based chemicals. Before beginning any cleaning of the cuber, the ice in the storage bin or dispenser must be removed.
WARNING: When using any chemical, rubber gloves and eye protection should be worn.
WARNING: Do not remove the small clear tube from the fitting located in the water pan. Doing so will result in erratic behavior of the ice machine.
Cleaning Procedure if there is Ice on the Evaporator Plate.
1. Turn the power switch on.
2. Press the clean button to start a 4 minute defrost cycle (button is located on the front of the control panel).
3. After harvest cycle, add ice machine cleaner and follow cleaning procedure.
Use ice machine cleaner on a coarse-surface cloth material (such as terry cloth) and wipe down the inside wall of the evaporator area, the water pan, the water curtain and the plastic water deflector. If the water distributor tube has heavy scale build-up, remove and soak it in full-strength nickel safe ice machine cleaner (or exchange the tube and clean the scaled tube at a later date). *See figures and #6 and #7.
Cleaning the Water System and Evaporator
1. Turn the power switch to “OFF”.
2. Remove all ice from the storage bin.
3. Remove the water curtain(s), pour 1/2 oz. of ice machine cleaner down the top of the evaporator. The cleaner will drain into the water pan.
4. Remove the water distributor tube (refer to fig. 10), disassemble water distributor tube (refer to fig. 11), and clean with the brush and “Calgon Nickel Safe” ice machine cleaner.

7. Turn the power switch to “ON” , allow the compressor to start, and depress the clean button two times on the front of the electrical box.
8. The unit will run through a fifteen (15) minute cleaning cycle. This includes 3 rinse cycles.
9. Once the cleaning cycle finishes, the error LED will flash 6 times.
10. When the clean cycle is complete, turn the power switch to “OFF” for five (5) seconds, then to “ON”. The unit will return to normal operating mode. Discard the first batch of ice produced.
NOTE: Please Take Note of the Following:
S Ice machines should only be cleaned when needed, not by a timed schedule of every 60 days, etc. S Should your ice machine require cleaning more than twice a year, consult your distributor or dealer about
proper water treatment.
Sanitizing the Water System and the Evaporator
NOTE: To be performed only after cleaning the ice machine:
1. Turn the power switch to “OFF”.
2. Add 1/4 ounce (7.08 g) sodium hypochlorite solution (common liquid laundry bleach) to the water pan. You may also use a commercial sanitizer such as Calgon Ice Machine Sanitizer following the directions on the product label.
3. Turn the Cuber power switch “ON” allowing the compressor to start. Depress the clean button two times on the control board. The unit will run through a 15 minute sanitizing cycle.
4. Once the sanitizing cycle is complete, the error LED will flash 6 times. Turn the power switch to “OFF” for 5 seconds and then turn to “ON”. Discard the first batch of ice produced.
5. To sanitize the bin and other surface areas, use 1 ounce of liquid bleach per gallon of water and wipe all areas with the solution. Or use a commercial sanitizer.
6. Cleaning and sanitizing are now complete. Cuber may be returned to normal service.
