GENERAL
FREIGHT DAMAGE CLAIMS PROCEDURE
The deliverer of your equipment (freight company, distributor or dealer) is responsible for loss or damage of your
shipment. All claims must be filed with the deliverer of your equipment. Please follow the steps below to determine if your shipment is satisfactory or if a claim must be filed:
1. Check the number of products delivered against the number of products listed on the delivery receipt.
Should the totals not match, have the driver note all errors on both copies and both you and the driver sign
and date said notation.
2. Inspect all cartons for visible damage. Open and inspect as required before the driver leaves and have him
or her note any damage on the receipts. All damaged claims must be inspected within 15 days of delivery.
Notify your carrier immediately if concealed damage is found after delivery.
3. Should concealed damage be found when product is unpacked, retain the packing material and the product
and request an inspection from the deliverer.
4. All claims for loss or damage should be filed at once. Delays in filing will reduce the chance of achieving a
satisfactory resolution to the claim.

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.

LEG INTO BASE
NOTE: Bin adapter and condenser 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.
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.
3

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?

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”. Supply line must be 1/2” pipe.

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.
W ATER REGULATING VALVE
The water regulating valve is used on water-cooled cubers only. The valve is installed in the condenser outlet
water line. It’s function is to control the proper operating head pressure by regulating the amount of water flowing through the condenser. The valve is adjustable and factory set to maintain condenser discharge water temperature @ 108/112_F (42-44_C). Setting the water regulating valve to maintain discharge water temperature
eliminates the need to enter the sealed refrigeration system. When checking the valve, the water temperature
should be taken as close to the condenser discharged as possible. The water temperature will equate to operating head pressure of approximately 310 PSI (21.1 BAR).
Should adjustment be required, the valve has an adjustment stem on the top of the valve. After allowing the
cuber to operate for 10 minutes in the ice– making mode to balance the system, turning the adjusting stem CW
will increase the discharge water temperature, and CCW will decrease the discharge water temperature.
The water regulating valve must close off condenser water flow completely during the “hot gas” harvest cycle.
There should be no discharge water flowing out of the condenser during the harvest cycle. Should the valve fail
to close during the harvest mode, the condenser will continue to condense the compressor discharge vapor
needed for the harvest cycle and this will result in long harvest times.
Also discharge water temperature below 108_F /112_F will result in long harvest times.
Leaking (bypassing) water regulating valves are normally the result of scale build-up on the valve diaphragm
and the valve should be flushed, not replaced. To flush the valve, open the adjusting stem wide open CCW (or
force the valve spring up with a screwdriver), open and close the water supply to the condenser resulting in the
flushing action. Should this not correct the problem, replace the valve diaphragm. This can be done without entering the sealed refrigeration system.
Damage to the water regulating valve may also be caused by water hammer. Water hammer will result from the
condenser inlet and outlet water lines being reversed or defective valve stops in the water supply line. Proper
installation of water–cooled equipment should always include an anti-water hammer standpipe in the supply inlet
line as close to the cuber as possible.
