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 on all sides and
top 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 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.

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.

THREAD LEVELING
LEG INTO BASE

NOTE: Bin adapter andcondenser air baffles may be required in certain installations.

DISPENSER INSTALLATION

The proper cuber/dispenser installation package should be ordered. This package will include gasket material
and hold-down bracket.

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 120 PSI (8.16
BAR).

NOTE: Water filters larger then 5 microns do not give proper protection. Water pressures above 80

PSI (5.44 BAR) will destroy the filter.

DRAIN LINES: Bin and cuber drain lines must never be connected together and must be vented.
NOTE: All HP-62 (R404A) ice machines have a voltage range of –5%, +10% from the serial palte rating.

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.

INSTALLATION CHECK POINTS

1. Has bin and cuber been leveled and sanitized?

2. Does electrical and plumbing meet code requirements?

3. Check correct operating water level in the water pan.

4. If water-cooled, are inlet and drain connections to condenser correct to prevent “water hammer”?

5. Are drain lines separate and vented?

6. Is there 6I clearance on all sides and top for proper air circulation?

7. Does the water curtain move freely, and does the float valve shut off incoming water to the water pan?

START-UP AND CHECK OUT

1. Turn the Cuber’s power switch to the clean (pump only) position. The water pump only should be opera-
tional. Wipe the top extrusion briskly with a ScotchBrite pad. Check for an even, steady flow of water over
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.

Power Switch

NOTE: On the IACS222/IWCS227 to service the float valve:

1. Compress the John Guess fitting remove the 1/4” tubing.

2. Remove the screws that hold the float bracket to the liner wall.

3. Carefully remove float strainer and bracket as one assembly.

4. Reverse procedure to reinstall.
Should service be required on the float valve or strainer, turn the water supply off, loosen the float,
hold down nut and remove the float and strainer as an assembly for ease of service.

2. Place the Cuber’s power switch in the ON position. After a 2-second delay the compressor will start. The

condenser fan will operate when the condenser sensor signals the circuit board its temperature is 100_F
(38_C). The water pump will operate when the evaporator cools to 25_F (–3.9_C). Depress the manual
harvest switch (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 and dump valve will close terminating the dump cycle.

3. Hold the water curtain open for a maximum of 30 seconds; the Cuber should shut down. Release the water
curtain(s). When the curtain(s) closes, there will be a 2-second delay, then the compressor will start and
the start-up process should begin for the next ice-making mode.

4. If all Cuber operation is as stated, allow product to operate and produce one slab of ice, then discard the
ice. Allow the Cuber to continue operation to fill the storage bin.

OWNER -OPERATOR

The installation is not complete until you are sure the owner-operator understands the cuber operation and his
or her responsibility of preventative maintenance.

Does the owner-operator know:

1. Location of electrical disconnect switch and water shut-off valves?

2. How to start and/or shut down the product, clean and sanitize it?

3. Bin full operation and reset operation of high pressure cutout (water-cooled and remote products only)?

4. How to clean the condenser and fan blade?

5. Whom to call for product information and/or service?

CLEANING PROCEDURES

Approved ice machine cleaners by brand names:

S Lime–A–Way
S Calgon Nickel Safe (green color only)

NOTE: All ice machine cleaners labeled safe for nickel ARE NOT the brand CALGON NICKEL SAFE.

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.

PREP – CLEANING

Use full-strength 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 evaporator plastic extrusions. If the wa­ter distributor tube has heavy scale build-up, remove and soak it in full-strength ice machine cleaner (or ex­change the tube and clean the scaled tube at a later date).

Cleaning the Water System and Evaporator

1. Set the switch to Clean and allow any ice on the evaporator to release and melt away.

2. Remove all ice from the storage bin.

3. Remove the water curtain(s), pour 1/2 oz. of ice machine cleaner down the rear key-slot openings. The
cleaner will drain into the water pan.

4. Return the water curtain(s) to their proper operating positions.

5. Add 3 oz. for a single evaporator, or 5 oz. for a dual evaporator of “Calgon Nickel Safe” or “Lime-A-Way”
ice machine cleaner directly into the water pan. The float will balance with inlet water. Set switch to
CLEAN, circulate for a maximum of 15 minutes.

6. Depress and hold the dump switch to allow the cleaner to drain away.

7. Fill the water pan with clean fresh water, circulate for approximately 3 minutes. Depress and hold the
DUMP switch and allow the water to drain away. Repeat the procedure 3 times.

8. After third rinse cycle, place product power switch in ice position. Allow Cuber to produce one slab of ice –
DISCARD THE ICE.

9. When the clean cycle is complete, return cuber to normal operating mode.

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 PROCEDURES

NOTE: To be performed only after cleaning the ice machine:

1. Add 1/4 ounce (7.08 g) sodium hypochlorite solution (common liquid laundry bleach) to the water pan and
allow the pump to circulate the solution for 5 minutes. You may also use a commercial sanitizer such as
Calgon Ice Machine Sanitizer following the directions on the product label.

2. Turn the Cuber power switch off and depress and hold the dump switch to drain the water pan.

3. 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.

4. Place the Cuber power switch in the ice position. Discard the first batch of ice produced.

5. Cleaning and sanitizing are now complete. Cuber may be returned to normal service.

1. With the proper water level in the water pan, start the water pump to circulate the water. Check that the
float will return water level to original setting and stop inlet water.

2. There is a flow washer in the inlet side of the float assembly that will control inlet water pressure from
20/120 PSI (3.4/8.16 Bars). This will prevent float flutter. In low water pressure conditions, 20 PSI (1.37
Bars) or less, the flow washer may have to be removed from the float assembly for proper volume.

ADJUSTING BRIDGE THICKNESS

TOP ROW
3/8I - 5/8I DIMPLE

CENTER
1/8I BRIDGE

BOTTOM 2 ROWS
3/16I - 1/4I BRIDGE

For optimum ice production and maximum cube separation, the ice
connecting the individual cubes should be a minimum of 1/8I (.32cm)
thick at the center area of the ice waffle.

BRIDGE 1/8I (0.32 cm)

It is normal for the ice slab 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. 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
CW one full turn. Allow two cycles before determining if

additional adjustments are required.

2. Thicker Bridge – turn the ice thickness “pot” adjusting screw CCW

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 “float” 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 300/310 PSI head pressure.

CIRCUIT BOARD DIAGNOSTIC PROCEDURE

Turn the power switch to the “ON” position. The D-5 red LED (error indicator) will be illuminated for 2 seconds.
After the D-5 red LED goes out, short across the bottom two terminals of the Test Plug with a jumper wire or a
pocket screwdriver and then remove the jumper. The circuit board is now in the test mode.

One of these two conditions will exist:

S If the Ice Thickness Potentiometer is within the factory setting the D-5, red LED will flash continiously.
S If the Ice Thickness Potentiomater is not

In either case the Green LED indicators will illuminate for 2 seconds each in the sequence shown below. They
will continue to sequence until you turn the power off and stop the procedure.

D-11 Green Hot Gas
D-12 Green Water Pump
D-14 Green Contactor
