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 re-
ceipt. 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 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 clearance at the front for proper air cir-
culation. 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.
FIGURE 1. INSTALLATION
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 120 PSI
(8.16 BAR).
Important: Water filters larger then 5 microns do not give proper protection. Water pressures
above 80 PSI (5.44 BAR) will destroy the filter.
Important: Bin and cuber drain lines must never be connected together and must be vented.

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 clearance at the front of the machine for proper air circulation?
7. Does the water curtain move freely, and does the float valve shut off incoming water to the water
pan?
8. 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 the plate.

START-UP AND CHECK OUT
1. Turn the cuber’s power switch to the clean (pump only) position. The water pump only should be op-
erational. 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 dis-
charge. The water pan should refill and the float should stop the incoming water supply.
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 that its tempera-
ture is 100_F (38_C) The water pump will operate when the evaporator cools to 25_F (–3.9_C). De-
press 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 water curtain open for a maximum of 30 seconds; the product 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 product operation are as stated, allow product to operate and produce one slab of ice, then dis-
card the ice. Allow the product 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:
SLime–A–Way
SCalgon 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 extru-
sions. If the water distributor tube has heavy scale build–up, remove and soak it in full-strength ice ma-
chine cleaner (or exchange the tube and clean the scaled tube at a later date).
CLEANING THE WATER SYSTEM & EVAPORATOR
1. Set the switch to CLEAN and allow the ice on the evaporator to release and melt away.
2. Remove all ice from the storage bin.
3. Remove the water curtains, 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 curtains to their proper operating position.
5. Add 3 oz. for a single evaporator, or 5 oz. for a dual evaporator of “Calgon Nickel-Safe” or “Lime-A-
Away” ice machine cleaner directly into the water pan. Set switch to CLEAN, circulate for a maxi-
mum of 15 minutes
6. Depress and hold the dump switch to allow the cleaner to drain away.

7
7. Fill the water pan with clean fresh water, circulate for approximately 3 minutes. Depress the DUMP
switch and allow the water to drain away. Repeat this procedure 3 times.
8. After third rinse cycle, place product power switch in ice position. Allow product to produce one slab
of ice – DISCARD THE ICE.
9. When clean cycle is complete, return cuber to normal operating mode.
NOTE: Please Take Note of the Following:
SIce machines should only be cleaned when needed, not by a timed schedule of every 60
days, etc.
SShould your ice machine require cleaning more than twice a year, consult your distribu-
tor or dealer about proper water treatment.
POWER SWITCH
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 sani-
tizer such as Calgon Ice Machine Sanitizer following the directions on the product label.
2. Turn the product power switch off and depress 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 product power switch in the ice position. Discard the first batch of ice produced.
5. Cleaning and sanitizing are now complete. Product may be returned to normal service.

DUMP CYCLE
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 the inlet water.
2. There is a flow washer in the inlet side of the float assembly that will control inlet water pressure
from 50/120 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 fill volume.
FLOW CONTROL WASHER FLAT SIDE UP
FIGURE 5. FLOW CONTROL WASHER
3. Push the manual DUMP switch – allow dump action to drain the water pan. When you release the
momentary switch, the pump will stop and the float will return the water level back to its original set-
ting and shut off the water supply.
4. You have the option of selecting dump cycle intervals of:
Severy cycle;
Severy 3rd cycle;
Severy 5th cycle;
Severy 7th cycle.
Remember, the higher the mineral content in the water supply the more often it will be required to dump
the water and/or clean the product if proper water treatment is not used.

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

FIGURE 7. CUBE SEPARATION
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.
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.
Using the proper ice deflector will insure a better seperation and allow for a more complete bin fill pattern.
TOTAL ICE CAPACITY
Ice capacity of any ice maker is affected by many operating conditions, such as water and air tempera-
ture 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% in-
crease in cycle time and capacity decrease of approximately 17%.
