NOTE:

Newly installed electromechanical control devices will suffer variations in their adjustment caused

by the machine’s own functioning. Once a second adjustment of these devices is carried out, this

should be good for several years. It is recommended, however, to check these devices yearly,

this is best done between October to April.

SAFETY TRIP (CIRCUIT-

BREAKER) IN NEW MACHINES WILL SWITCH OFF THE MACHINE

DUE TO ONE OF THE FOLLOWING:

• Ambient temperature is below 5ºC

• Water temperature is below 5ºC

• Evaporation temperature is below -20ºC

• Cooling temperature below +30ºC

• Refrigerant charge slightly low

In the first three cases, so long as temperatures do not drop below 3ºC (machine limit), re-

adjust

fan pressostat to 42ºC and check that by-pass opens at -21ºC. In the last two cases bypass will

open and close very often. Adjust bypass, fan pressostat and add refrigerant if necessary.

Gearbox current consumption should be between 1.9A (min) and 2.6A (peaks) with an average

2.2A. Safety trip will work at 2.4-2.6A and switch off the machine immediately.

If the machine is over 2 years old, also inspect the auger, bearings, and grease on bearings.

In case of excess current consumption, you can verify that the problem is in the gear-

box by

either physically detaching gearbox and motor from auger and checking current consumption, or

by removing only the brown wire which provides current to the compressor.

In order to avoid damage to the gear-box, the safety trip is very sensitively adjusted and may trip

easily. You may teach the end user to re-connect the machine (by inserting a pen/screwdriver

through the front grille blades). This is best done after a one hour pause.

Should the machine trip on a regular basis (more than once a week), the end user must get in

touch with the service department.
