INSTALLATION

The power supply will be connected with the icemaker MUST have its own fuse as you in drawing 1.

The fuse must be:
For the ice makers C-250, C/M-300, C/M-400, C/M-600,
C/M-800…………………………………………10 Amps

For the ice makers C/M-1200, C/M-1600, C/M-2800
……………………………………………………..16 Amps

Do not pour water on your icemaker or the power cord
Do not install the devise in small and narrow places that impede the free airflow IN and out of the air-duct.
Always leave 25-30cm distance from the air – duct of your icemaker before put anything that pre-vents airflow.
Do not ever install your icemaker near heat sourc-es.
The ambient working temperature MUST not exceed 32 Celsius nor underneath 10 Celsius.
If your icemaker works in a warm ambient temperature over 42 Celsius and starts and stops within a few seconds, then there is a risk of destroying your compressor.

Description

Inside the plastic bag you should find everything you need to start producing ice…

• Lift the icemaker from one side, about 25 cm from the ground, and place its feet. Same do from other side.
• At the back of the ice maker you will find an inlet and outlet of water. Place one side of granual pipe in outlet in outlet of icemaker and the other side to the drain of store – home. The other pipe, which have bolt in each side, is to be connected to the inlet of water. But first place in each bolt a rubber insulator (there are 2 rubbers in plastic bag). After that connect on side to inlet of icemaker and the other side to tap.
• Lastly allow inlet of water (open the tap) and then connect the power cord to plug.
  Now the apparatus will be supplied with tap water and after 2 min will start the cycle.

Do not place icemaker in position that allows the drain to be higher from outlet of water.

OPERATION

Your icemaker has been adjusted from the factory to function after installation, without any other need of technician. But here you’ll find how to make adjustment to your icemak-er. Please note the adjustments are so easy to be done without the need of technical knowl-edge.

Find the adjustment switches

• Pull up the front cover of device and the adjustment switches will be appear.
• Find the screw type with the numbers around it. This switch enables the fluctuation of the size ice size.
• With a screwdriver turn the switch right for increasing volume in each ice piece. Or turn it left to decrease volume in each ice peace.
  Minimum weight for C models is 17 grams and max 32 grams.
  Minimum weight for M models is 20 grams and max 28 grams.

Do not fluctuate marginal the adjustments, on left end position the icemaker stops to function. On right end position the icemaker will make a big mass of ice. If such thing happen you must stop the ice maker and wait till the ice melts. Or you can make the ice melt quicker by boiling water and pour it on top of icemaker, after you take off first the top cover. So, please make adjustments gradually per working cycle, till you will be satisfied with the size of ice.

• Near the switch we mentioned there is another screw type switch.
  Through this switch is possible to make adjustments with the storage capacity. Same turn right for increase the capacity and left for decreasing the capacity of your icemaker stor-age.

• The icemaker stops working when ice reaches the point you wish and starts again when a quantity of ice will be taken.

DO NOT! Try to adjust the red switch.
This is a timer and never needs adjustment.
However, if you need to adjust it you should turn ONLY clockwise.

TIPS

For having the best performance of your ice maker, you should clean once a month its condenser, mostly in summer time. The condenser is behind the front cover. Clean it with UP and DOWN movements ONLY!! Do not supply your icemaker with water from a tanker, which is exposed to the sun.

• For cleaning the water storage, distributor and sprayers:
  First lift off the top cover, then take off the door. Now pull up the white flags. Behind the flags is the water storage. Take off the sliding conveyor. Place your hands down of distribu-tor and lift it first. Rotate it 60’ and pull it out gently in such way, so you will disconnect the distributors pipe from pumps pipe. Now you can clean the icemaker. Please also consider the sprayers, which are on distributor. Take them off and clean them by brushing with toothbrush or mix water vinegar. Be careful when you are going to connect them in the dis-tributor, you must put in such way to be parallel in to each other.

• For having a quick cleaning of your icemaker just poor mix of water vinegar in water stor-age, then connect with 1.2 m Φ1/2’ pipe the white hose you disconnect before the distribu-tor. The other side of the long pipe places it in water storage. Now start the ice maker. Leave for 10 min and then stop it. After that, wash the water storage with water and then dry it. Connect everything from last piece to first. And place the machine into function again.

• The ice maker has been designed for producing ice and not as storage to preserve fruits or bottles or in general to preserve foods, drinks. For example leaves from fruits or etiquettes from bottles could obstruct the drainage system.

• In situation of malfunction of your ice maker, first refer to troubleshootings section. If nothing performed after troubleshooting guiding, please ask for assistance by authorized personnel.

• We suggest installing before inlet of water a softener in case the supplied water is hard. The softener could be a mechanical filter.

• If you intent to use your icemaker periodically, through seasons, it is better to follow pro-cedure of cleaning the device, plus stop power supply and blow air in pump circuit, in order to remove all water from pump circuit.

• In case you need to transport your ice maker it’s better to place it at its feet. If thaw cannot be followed and the icemaker is placed in some else way, then after transportation leave it for 2 hours in its feet before using it.

• If you decide to scrap your ice maker, please proceed as follows:

  1. First disconnect power cord and cut the wire from the point it comes out of the icemak-er.
  2. Dispose all materials to each kind.
  3. Make sure refrigerant coolant and oil from compressor, are not escaping to environ-ment.
  4. Make sure all above, proceeded in compliance with your country regulations.
  • Electrical safety against shock, is clearly bind with the appropriate connection of the ice maker’s power cord to an efficient earthling system. Be sure before installation that there is an efficient earth system.
  • After installation destroy any plastic bag, that could cause suffocation to a child.
  • Do not leave a child to reach the ice maker with the intent to play with it.

TROUBLESHOOTING

The ice maker doesn’t work

| Check the plug – if there is any power.

Check for short circuit – check fuses.

Check if the storage is full of ice. If so remove ice to perform production.

---|---

The icemaker works but it doesn’t produce ice/or is melting in the storage

|

Check the sliding conveyor. It might have remove from its position and prevent ice to fall in the storage by keeping it in the Water storage (behind flags). Light sliding convey- or slightly to up step of water storage.

Check the drain, maybe the water comes back to storage and melts the ice. If so, you must install icemaker higker from drain.

Last Unscrew back over, on left you will find a blach pipe. Squeeze it so any obstacle wil remove.

The produced ice is unformed/bad shaped

| You must clean the distributor and sprayers. (See TIPS in this manual)

Check for possible rubbish in filter of electro valve or pump.

Check pump.

Check electro valve.

The icemaker is working for long hour/s without producing ice

| Lift the front cover of device and with the brush clean with UP and DOWN movements only the condenser (The component it is first to your disposal).

Check the working temperature of the ice maker.

If it is over 42 Celsius, you have to decrease the ambient working temperature, or install the ice maker somewhere else.

If nothing of above change the problem Please call for assistance for authorized per- sonnel, because the icemaker has lost its refrigerant. FREON (R452A) due to trans- portation, hit, of from long use.
