IceTech

F.A.Q.

It Starts and stops constantly

1. Do you have a clean air condenser? If it is dirty it should be cleaned. If it is a machine cooled by water, you should check that the water comes in and out of the condenser.

2. Is the condensation pressure switch working correctly? The pressure switch must connect the fan when the pressure reaches 18 Bar and must disconnect the fan when the pressure is at 15.5 Bar.

3. Is the high pressure safety pressure switch working properly? You must stop the machine if the pressure reaches 30 Bar. It will restart the machine when the pressure returns to 21 Bar.

A lot of water falls through the ice chute

1. The buoy installed in the blue water tank must be regulated to prevent that the water leaves the overflow and falls through the ice chute.

2. If the evaporation temperature is higher than it should be, the ice can get very wet and water can fall out of the ice chute. (The correct temperature of each machine should be indicated)

Low production

1. ¿Qué temperatura de evaporación tiene? La temperatura de evaporación influye mucho en la producción.

2. ¿Qué temperatura de agua y ambiente tiene? La producción de las máquinas está calculada con 15ºC de agua y 20ºC de ambiente. Por encima de esta temperatura, la producción disminuye.

The ice comes out very soft

1. Which evaporation temperature does it have? If the temperature is higher than it should be, the ice comes out softer. (indicate temperatures by model)

2. What temperature of water and environment do you have? The production of the machines is calculated with 15ºC of water and 20ºC of environment. Above this temperature, the production decreases.

The machine does not produce ice

1. On CD units, check that the cleaning switch (black color) is on I (compressor running).

2. Check that water reaches the evaporator (transparent tube without bubbles).

Failure due to thermal gear motor

1. Check that water reaches the evaporator (transparent tube without bubbles).

2. Clean the evaporator according to the protocol.

3. Reset the thermal relay if it has tripped. If necessary, increase the intensity of the relay.

4. Check the direction of the gear motor rotation (always counterclockwise).

5. Check the evaporation temperature, it must not be less than the value of each unit.

The machine doen’t drive water to the evaporator

1. Check if voltage reaches the water pump

2. Check if water enters the machine

3. Check the status of the water pump filter

The machine produces white ice

1. Check the status of the injectors. Possibility of obstruction due to dirt.

2. Possible lack of water.

3. Check if the machine runs out of water during ice production.

It Starts and stops constantly

1. Do you have a clean air condenser? If it is dirty it should be cleaned. If it is a machine cooled by water, you should check that the water comes in and out of the condenser.

2. Is the condensation pressure switch working correctly? The pressure switch must connect the fan when the pressure reaches 18 Bar and must disconnect the fan when the pressure is at 15.5 Bar.

3. Is the high pressure safety pressure switch working properly? You must stop the machine if the pressure reaches 30 Bar. It will restart the machine when the pressure returns to 21 Bar.

The ice is empty/small

1. In what number is the cycle thermostat regulated? On the thermostat there is a red dot indicating the factory set?

2. The ice come up fuller / larger increasing the number of the thermostat regulation. The regulation goes from 1 to 7 (more number indicates fuller)

The water doesn’t enter in the ice machine

1. Check the status of the buoy micro.

2. Check if the voltage reaches the water inlet valve.

3. Check the regulation of the buoy.

There is no ice and the machine is stopped

1. Check the micro installed on the connecting rod of the water bin

2. Check that the high pressure safety pressure switch has continuity.

3. Check the status of the relay

The ice doesn’t detach from the evaporator

1. The fingers of the evaporator must be clean and without limescale.

2. Check that the hot gas valve opens when the relay sends voltage.

There is a block of ice in the evaporator

1. Is the motor that moves the paddles working?

2. Check the motor micro that moves the paddles. This micro activates the hot gas valve.

The bin where the water is stored doesn’t go down

1. Check that the relay sends voltage to the turner motor

2. Check if the voltage reaches the turner motor

3. Check that the turner motor doesn’t have the anchor loose, and that the rod of the tray is positioned correctly.

The ice bin where the water is stored doesn’t stop rising and falling

1. Check the mics of the turner motor. These mics are responsible of controlling the movement of the engine.

2. Check the micro of the agitator motor micro (paddles engine)

The ice bin doesn’t have ice and the machine is stopped

1. Regulate the stock thermostat installed in the electrical panel. More number indicates more ice in the ice bin.

2. Check the status of the high pressure safety pressure switch.

The ice remains in the evaporator

1. Is the machine well leveled? The machine must be completely level or even angled forward.

2. The evaporator must be clean. It should be cleaning with phosphoric acid 50% and with hot water.

The compressor doesn’t work

1. Check that the cleaning switch installed in the electrical panel is in the ICE position.

2. Does the voltage arrive to the compressor? If voltage arrives and it doesn’t work, the compressor must be replaced.

There is no water in the ice bin (modular machine)

1. Check the water level probe installed next to the water pump. This probe detects the water level in the ice bin.

2. Check the status of the electronic board

The machine is stopped and there isn’t ice (modular machine)

In the lower left side of the curtain there is a magnet which detects the ice level and for the machine. Check that the magnet and the micro of this magnet are in its position.

Ice cubes come out with hollows

1. Check that the sensor thickness is not too close to the evaporator (3 to 5 mm).

2. Check that the drain valve closes correctly. If it remains open due to lime, the water is lost through the drain during the manufacture.

3. Check that the hot gas valve does not remain open during manufacturing.

Machine at a standstill

1. Check that tension reaches the electrical panel.

2. Check that the main switch is on I (on the right)

3. Check possible failure indicated in electrical panel lights

4. Check that the variable speed drive doesn’t alarm.

5. Check at 3 minutes that the starting timer is timing and works correctly.

6. If there is a lack of water, check that the inlet pressure is correct.

7. If it is stopped by high / low pressure, when timing check that the liquid solenoid opens correctly.

8. Check that remote stop or security button are not activated.

The Ice comes out with water from the machine

1. With the water tap adjust the water in the upper distributor, so that the level is below the mark on the center screw of the tray.

2. Check that the tray that collects the water (lower part) is not broken.

3. Check the water pipes irrigation, if necessary, cover the last one (before the milling cutter).

4. Check that the distributor pipes are not broken.

The machine doesn’t make ice and indicates full of ice

1. Check photocell, bridge electrical panel on terminal to verify that it is a photocell fault.

2. Clean the sensor if it is dirty.

3. Check that the light beam has the inclination necessary (minimum operation distance 25 cm). If a conduit for ice fall has been installed, make a window in the light beam zone.

4. Check cabling, as well as possible second photocell.

Flake thickness is not suitable

In units with frequency shifter, lower the frequency, as far as 30 Hz, to increase flake thickness.

Very small flakes

For very soft water, the flake (size) can be increased by adding salt to the water, 3%.

Low ice production

1. Check that the water pump functions correctly, and that the water filter is not obstructed.

2. Check the evaporator. The whole evaporator should be cold. If necessary, adjust expansion valve, to -22 ºC.

3. Check that there is no refrigerant leakage.
