GENERAL INFORMATION AND INSTALLATION

A. INTRODUCTION

These Cubers are quality designed, engineered and manufactured. Their ice making systems are thoroughly tested providing the utmost in flexibility to fit the needs of a particular user. These ice makers have been engineered to our own rigid safety and performence standards.

NOTE.

built into this icemaker, it is important that installation and maintenance be conducted in the manner outlined in this manual.

B. UNPACKING AND INSPECTION

1. Visually inspect the exterior of the packing and skid. Any severe damage noted should be reported to the delivering carrier and a concealed damage claim form filled in subjet to inspection of the contents with the carrier’s representative present.

2. a) Cut and remove the plastic strip securing the carton box to the skid.

the polystyre protection sheet. corners and then remove the carton.

3. Remove the front and the rear panels of the unit and inspect for any concealed damage. Notify carrier of your claim for the concealed damage as stated in step 1 above.

4. Open the bin door and remove all internal support packing and masking tape.

To retain the safety and performance

b) Cut open the top of the carton and remove c) Pull out the polystyre posts from the

7. See data plate on the rear side of the unit and check that local main voltage corresponds with the voltage specified on it.

CAUTION. Incorrect voltage supplied to the icemaker will void your parts replacement program.

8. Remove the manufacturer’s registration card from the inside of the User Manual and fillin all parts including: Model and Serial Number taken from the data plate. Forward the completed self-addressed registration card to the factory.

C. LOCATION AND LEVELLING

WARNING. This Ice Cuber is designed for indoor installation only. Extended periods of operation at temperatures exceeding the following limitations will constitute misuse under the terms of the Manufacturer’s Limited Warranty resulting in LOSS of warranty coverage.

1. Position the unit in the selected permanent location. Criteria for selection of location include:

a) Minimum room temperature 10°C (50°F)

and maximum room temperature 40°C (100°F).

b) Water inlet temperatures: minimum 5°C

(40°F) and maximum 35°C (90°F).

c) Well ventilated location for air cooled models. Clean the air cooled condenser at frequent intervals.

d) Service access: adequate space must be left for all service connections through the rear of the ice maker. A minimum clearance of 15 cm (6") must be left at the sides of the unit for routing cooling air drawn into and exhausted out of the compartment to maintain proper condensing operation of air cooled models.

5. Check that refrigerant lines do not rub against or touch other lines or surfaces, and that the fan blade moves freely.

6. Use clean damp cloth to wipe the surfaces inside the storage bin and the outside of the cabinet.

NOTE.

With the unit in “built-in” conditions, the ice production is gradually reduced in respect to the levels shown in the graph, up to a maximum of 10% at room temperatures higher than 32°C.

The daily ice-making capacity is directly related to the condenser air inlet temperature, water temperature and age of the machine.

To keep your CUBER at peak performance levels, periodic maintenance checks must be carried out as indicated on Cleaning Section of this manual.

2. Level the unit in both the left to right and front to rear directions.

Page 2

D. ELECTRICAL CONNECTIONS

See data plate for current requirements to determine wire size to be used on electrical connections. All icemakers require a solid earth

wire.

The ice machines are supplied from the factory completely pre-wired and require only electrical power connections to wire cord provided on the back of the unit. Make sure that the ice machine is connected to its own circuit and individually fused (see data plate for fuse size). The maximum allowable voltage variation should not exceed -10% and +10% of the data plate rating. Low voltage can cause faulty functioning and may be responsible for serious damage to the overload switch and motor windings.

NOTE.

All external wiring should conform to national, state and local standards and regulations. Check voltage on the line and the ice maker’s data plate before connecting the unit.

E. WATER SUPPLY AND DRAIN

CONNECTIONS

General

When choosing the water supply for the ice cuber consideration should be given to:

a) Length of run b) Water clarity and purity c) Adequate water supply pressure

Since water is the most important single ingredient in producting ice you cannot emphasize too much the three items listed above. Low water pressure, below 1 bar may cause malfunction of the ice maker unit. Water containing excessive minerals will tend to produce cloudy coloured ice cubes, plus scale built-up on parts of the water system.

fitting and a shut-off valve installed in an accessible position between the water supply line and the unit.

Water supply - Water cooled models (65-90)

The water cooled versions of series 65 and 90 require two separate inlet water supplies, one for the water sprayed for making the ice cubes and the other for the water cooled condenser. Connect the 3/4" male fitting of the water regulating valve using the flexible hose supplied with the unit to the cold water supply line with regular plumbing fitting and a shut-off valve installed in an accessible position between the water supply line and the unit.

Water drain

The recommended drain tube is a plastic or flexible tube with 18 mm (3/4") I.D. runs to an open trapped and vented drain. When the drain is a long run, allow 3 cm pitch per meter (1/4" pitch per foot).

A vertical open vent, at the unit drain connection, is also required for proper sump drainage.

Water drain - Water cooled models

The water drain line from the condenser, on water cooled versions, is internally connected with the drain fitting of the unit. It is strongly recommended therefore to install a vertical open vent on unit drain line high point to ensure good draining and to direct the drain line to a trapped and vented floor drain receptacle. This to make sure of the proper flow of the drained water as, in case of poor drainage, the water ranning out from the condenser may inopportunely flow, through the unit drain tubing, into the ice storage bin.

Water supply

Connect the 3/4" male fitting of the solenoid water inlet valve, using the flexible hose supplied, to the cold water supply line with regular plumbing

NOTE.

The water supply and the water drain must be installed to conform with the local code. In some case a licensed plumber and/ or a plumbing permit is required.

After having correctly installed the ice maker and completed the plumbing and electrical connections, perform the following “Start-up” procedure.

18-21-31-40 A. Remove the unit front panel and locate the

cleaning switch on the control box.

B. Set the cleaning switch in the cleaning position (II). This will close the electrical circuit to the water inlet valve and to the hot gas valve.

C. Switch ON the power line disconnect switch. Unit will start up in water filling phase mode. During this phase the components energized are:

WATER INLET SOLENOID VALVE HOT GAS SOLENOID VALVE

The Water pump and the Fan motor are also in operation.

D. Set the master switch to the ON position. The compressor switch must stay in the OFF position. This will close the electrical circuit to the water inlet valve and to the hot gas valve.

E. Switch ON the power line disconnect switch. Unit will start up in defrost cycle mode.

During this cycle the components energized are:

WATER INLET SOLENOID VALVE HOT GAS SOLENOID VALVE TIMER MOTOR

F. After completion of harvest cycle (about

three minutes) move the compressor switch to ON position.

NOTE.

During the defrost cycle, the water inlet solenoid valve is energized. The water flows through the valve to the back side of the evaporator platen and then down to fill up the icemaker sump tank for the next freezing cycle.

D. Let unit stay in water filling phase mode for about three/four minutes till water is coming out from the drain hose, then move the cleaning switch to the operation position (I).

50-65-90 A. Remove the unit front panel and locate the

timer shaft on the control box. B. Check that master and the compressor

switch located on the lower left hand side of the control box are both in the OFF position.

C. Rotate the timer shaft protruding through the front of the control box clockwise, until and audible click is heard indicating that the actuator arm of the microswitch has dropped into the cam slot (Fig. A).

OPERATIONAL CHECKS A. The unit now starts its first freezing cycle

with the following components in operation:

COMPRESSOR WATER PUMP FAN MOTOR in air cooled version

B. Check to see through the ice discharge

opening that the spray system is correctly seated and that the water jets uniformely reach the interior of the inverted cup molds; also make sure that the plastic curtain is hanging freely and there is not excessive water spilling through it.

C. The ice making process takes place thereby, with the water sprayed into the molds that gets gradually refrigerated by the heat exchanged with the refrigerant flowing into the evaporator serpentine.

D. On units 18-21-31-40 when the evaporator temperature reaches a preset value the evaporator thermostat or cube size control changes its contacts; the freezing cycle ends and starts the defrost or harvest cycle.

E. On units 50-65-90 the time clock does not rotate at the end of the harvest cycle. It starts later when the cube size thermostat control bulb (pig tail) located on the evaporator coil reaches a temperature of approx. -15°C (5°F).

Freezing time will range between 20 and 22 minutes in a 21°C ambient temperature, longer if above this temperature and shorter if below. The average complete cycle time is between 23 and 25 minutes.

F. Check, during the first defrost/harvest cycle, that the incoming water flows correctly into the sump reservoir in order to re-fill it and the surplus overflows through the overflow drain tube.

G. Check the texture of ice cubes just released. Right size must have a small depression (about 5-6 mm) in their crown.

If not, wait for the second defrost/harvest cycle before performing any adjustment.

H. If required on model 18, 21, 31 and 40, the length of the freezing cycle can be modified by turning the knob of the cube size control or evaporator thermostat located in front of the control box until the desired size is achieved.

• If the temperature of the room in which the machine is place is below 20°C, the cubes will tend to be partly hollowed out (see fig. on right).

• If, on the other hand, the room temperature is above 30°C the cubes produced will have a jagged rim of ice around the crown.

It should, however, be remembered that if the room temperature returns later to the 20 ÷ 30°C range, the knob indicator must once again be turned to point to the dot (see fig. below).

If the ice cubes are shallow and cloudy, it is possible that the ice maker runs short of water during the end of the freezing cycle or, the quality of the supplied water requires the use of an appropriate water filter or conditioner.

I. At the end of the defrost or harvest cycle hold a handful of ice cubes against the bulb of the storage bin thermostat; the icemaker switch OFF in about one-two minutes. Take out the ice from the storage bin thermostat. The ice maker should restart automatically in three-four minutes.

NOTE.

The bin thermostat is factory set at

1°C (35°F) OUT and 4°C (39°F) IN.

If it is thought necessary, the above situations can be rectified by, in the first case, turning the control knob (as little or as much as is required) clockwise and, in the second case, turning the knob to the right counterclockwise.

K. Re-fit the unit front panel then instruct the owner/user on the general operation of the ice machine and about the cleaning and care it requires.
