1.General Information and Installation Instructions

1.1Introduction

The Electronic 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 icemakers have been engineered to our own rigid safety and performance standards.

The VDE – SEV – WRC seals signify that it is listed with them and that it complies with the materials and manufacturing standards of them.

Note. To retain the safety and performance built into this icemaker, it is important that installation and maintenance is conducted as outlined in this manual.

1.2Unpacking and Inspection.

1.Visually inspect the exterior of the packaging and pallet. Report any damage to the delivery carrier and your distributor.

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

b)Cut open the top of the carton and remove the polystyrene protection sheet.

c)Pull out the polystyrene posts from the corners and then remove the carton.

3.

Remove the front and rear panels of the unit and inspect for any concealed damage. Report the damage to the distributor.

4.Remove all internal support packing and masking tape.

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

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

7.See the data plate on the rear of the machine and check that the local mains voltage corresponds with the voltage specified on the plate.

CAUTION. INCORRECT VOLTAGE APPLIED TO THE MACHINE WILL INVALIDATE THE WARRANTY.

1.3Location and Leveling.

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 Manufacturers Limited Warranty resulting in Loss of warranty coverage.

1.Position the machine in the selected permanent location. The criteria for the location includes:

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 40°C (100°F)

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

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

NOTE. With the machine in ‘built-in’ conditions, the ice product is gradually reduced in respect of the levels shown in the table, 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 also the age of the machine. To keep the CUBER at peak performance levels, periodic maintenance checks must be carried out as indicated in the Cleaning Section of this manual.

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

3.ELECTRICAL CONNECTIONS.

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

The ‘F’ series ice machines are supplied from the factory prewired and are fitted with a suitably fused thirteen Amp UK plug. The FCI models have a power cable that requires electrical connections to be made to the cable at the back of the machine, making sure that it is connected to its own circuit and individually fused (see data for the correctly fuse size).

The maximum allowable voltage variation should not exceed –10% and +6% 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 machines data before connecting the unit.

1.4Water 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 producing ice you cannot emphasize too much the three items listed above. Low water pressure below 1bar may cause the malfunction of the machine.

Water containing excessive minerals will tend to produce cloudy coloured ice cubes, plus scale build-up on parts of the water system

WATER SUPPLY.

Connect the male fitting of the solenoid water inlet valve, using the flexible tubing supplied, to the cold water supply line with regular plumbing

2

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

WATER SUPPLY - WATER COOLED MODELS.

The water cooled versions require two separate inlet water supplies on models 40 and 60, one to supply water for the ice production and one for the water cooled condenser.

Connect the male fitting of the condenser water inlet solenoid valve, using the second flexible tubing supplied, to the cold water supply line with regular plumbing fittings 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 18mm (3/4in) I.D. that runs to an open trapped and vented drain. When the drain is along run, allow 3cm pitch per metre (1/4in 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 to the high point of the drain line high enough to ensure good drainage and to direct the drain line to a trapped and vented floor drain receptacle.

This ensures proper flow of the drained water as, in the case of poor drainage, the water running out of the condenser may leak through the unit drain tubing into the ice storage bin or into the sump reservoir.

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

1.5Final Checklist.

1.Is the machine in a room where the ambient temperatures are within a minimum of 10°C (50°F) even in winter months?

2.Is there at least a 15cm (6in) clearance around the unit for proper air circulation?

3.Is the machine level? (IMPORTANT)

4.Have all the electrical and plumbing connections been made, and is the water supply shut-off valve open?

5.Has the voltage been tested and checked against the rating on the data plate?

6.Has the water supply pressure been checked to ensure a water pressure of at least 1 bar (14psi)?

7.Check all refrigerant lines and conduit lines to guard against vibration and possible failure?

8.Has the bin liner and cabinet been wiped clean?

9.Has the owner/user been given the User Manual and been instructed on the importance of periodic maintenance checks?

10.Has the owner/user been given the name and telephone number of the authorised Service Agency in case of breakdown.

2.2Start Up

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

ASwitch on the power to the machine. The unit starts its first freezing cycle with the following components in operation: COMPRESSOR

WATER PUMP

FAN MOTOR. (The condenser fan is controlled by a thermostat, factory set at approximately 33°C).

BCheck through the ice discharge opening that the spray plate is correctly seated and that the water jets uniformly reach the interior of the inverted cup molds; also make sure that the plastic curtain is hanging freely and that water is not spilling through it excessively.

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

DWhen the evaporator temperature reaches a pre-set value the evaporator thermostat changes its contacts, the freezing cycle ends and the defrost/harvest cycle starts.

Freezing time will range between 17 and 22 minutes (depending on model, see table) in a 21°C ambient. Longer time for temperature above, shorter when below.

Average complete cycle range is about 17 to 25 minutes (depending on model, see table above)

ECheck, 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 down the overflow drain tube.

During this cycle the components energised are: COMPRESSOR.

HOT GAS SOLENOID.

WATER INLET SOLENOID VALVE.

The FAN MOTOR and the WATER PUMP are also in operation if ambient temperature exceeds 33°C.

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

FCheck the texture of the ice cubes just released. The correct size has a small depression (about 5-6mm) in their crown. If not, wait for the second defrost/harvest cycle before making any adjustments.

2.3Adjustments

GIf after the second harvest the cubes are not correct adjustment to the evaporator thermostat may be necessary.

Remove the front panel and locate the cube size thermostat, using a flat bladed screwdriver turn towards the ‘+’ to increase the cube size and towards the ‘-’ to decrease the cube size. (See fig 1)

HTo check the bin full thermostat hold a handful of ice against the bulb of the storage bin thermostat, the ice maker will switch off in about one to two minutes.

Once the machine has stopped remove the ice and dispose of it, the machine will restart automatically in three to four minutes.

Note. The bin thermostat is factory set at 1°C (35°F) CUT OUT and 4°C (39°F) CUT IN. (The set temperature can be adjusted if required by using a flat bladed screwdriver turn towards the ‘+’ to increase the bin temperature and towards the ‘-’ to decrease the bin temperature). (See fig 1)

Refit the bottom front panel then instruct the owner/user on the general operation of the machine and about the cleaning and care it requires.

I.The machine may stop working if the condenser temperature exceeds the pre-set temperature of the OverTemperatureThermostat (non-adjustable) due to a very high ambient temperature, condenser fan failure, dirty/ blocked condenser. To restart the machine depresses the protruding button on the Alarm Reset.

I.The machine may stop working if the condenser temperature exceeds the pre-set temperature of the Over Temperature Thermostat (nonadjustable) due to a very high ambient temperature, condenser fan failure, dirty/ blocked condenser. To restart the machine, depress the protruding button on the Alarm Reset.

J.Changes to the defrost time. Under normal circumstances no adjustments should be necessary.

The fixed time can be adjusted by releasing the tension on the cam screw, turning the dial anti-clockwise to increase the defrost time and clockwise to decrease the defrost time, retighten the screw when the adjustment has been completed.

Note. If adjustment are made it will effect the freeze cycle.

Increasing the defrost time will shorten the freeze time so adjustments to the cube size thermostat may need to be made to increase the freeze temperature.

Decreasing the defrost time will increase the freeze time so adjustments to the cube size thermostat may need to be made to decrease the freeze temperature.

3.4Cleaning/Rinsing For F20, 40, 60, 85

A.Remove the bottom front panel and locate the changeover switch.

B.Remove the top cover to gain access to the evaporator.

D.Wait till the machine finishes its freeze cycle and then turn off the electrical supply to the machine.

D.Prepare the cleaning solution as per the manufactures instructions on the Ice Machine Cleaner.

Warning. The Ice Machine Cleaner contains Phosphoric and Hydroxyacetic acids. These compounds are corrosive and may cause burns if swallowed. If swallowed DO NOT induce vomiting, drink lots of water or milk and contact your Doctor immediately.

In case of external contact wash off with clean water.

E.Scoop out all of the ice cubes stored in the bin in order to prevent them from being contaminated by the cleaning solution then drain the water from the sump reservoir by removing the plastic overflow pipe. Once the water has drained from the sump replace the pipe.

F.Remove the evaporator cover and slowly pour the solution onto the evaporator platen. Use a soft brush if necessary to remove stubborn deposits.

G.Press the switch to the clean position and restore the electrical supply to the machine.

H.Leave the machine in the cleaning/rinsing mode for at least twenty minutes then turn the machine off at the electrical supply to the machine. It may be necessary to clean the water spray separately. If required remove the spray plate from the machine, mix a solution of the cleaner in a bowl or bucket and immerse the plate in it. When clean thoroughly rinse with clean water and re-fit it into the machine.

I.Drain the cleaning solution from the sump reservoir by removing the plastic overflow pipe. Once the solution has drained from the sump replace the pipe.

J.Pour two to three litres of clean water over the evaporator platen to rinse of the remaining solution and ensure sufficient water is in the reservoir. Ensure that the switch is still in the ‘CLEAN’ position and turn on the electrical supply to the machine. Leave the machine in the cleaning mode for at least five minutes to thoroughly rinse the entire water system.

K.Drain the rinsing water from the sump reservoir by removing the plastic overflow pipe. Once the rinsing water has drained from the sump replace the pipe and thoroughly wipe the interior of the machine.

L.Replace the evaporator cover and top service panel, turn on the electrical supply to the machine with the switch still in the wash position. Leave the switch in this position for approximately five minutes to allow the water reservoir to fill up.

M.Change the switch setting to the freeze position to start the freeze process.

N.At the completion of the freezing and harvest cycle make sure the ice cubes are the proper texture and do not have an acid taste.

Attention. If the ice cubes are cloudy-white and have an acid taste, discard them immediately by pouring warm water over them to prevent them from being used.

O.Once you are satisfied that all of the cleaning solution has been removed from the machine rinse the storage bin with clean water and wipe clean.

Remember. To prevent the accumulation of undesirable bacteria it is necessary to sanitize the interior of the storage bin with an antialgae solution each week.
