3 Description of the unit

built on the basis of the single-block principle.

The GM series includes air-cooled or water-cooled (optional) condensing units

They consist of:

4 Operation

Handling

1. a condensing unit placed outside the cold room;

2. an insulating panel (optional) for wall-thru instead of straddle installation;

3. an evaporator installed inside the room;

4. an electric control panel placed on the condensing unit;

5. a wall-mounted remote control panel (optional).

GM single blocks are compression units where cold is produced by vaporizing a

liquid refrigerant (HFC type) at low pressure in a heat exchanger (evaporator). The resulting vapour is brought again into the liquid state by mechanical compression at a higher pressure, followed by cooling in another heat exchanger (condenser). The compressor is hermetic, with reciprocating motion, supplied with single-phase or three-phase power. Defrost takes place automatically in pre-set cycles, by injecting hot gas (standard) or by means of heaters (optional); manual defrost is also possible.

The unit can be handled by lifting and transport means.

12.3 Troubleshooting

During operation following troubles may occur:

1 Compressor stops. The unit is equipped with an overtemperature device which stops the compressor every time the max. allowable temperature of motor windings is exceeded. Possible causes are:

- insufficient ventilation of the room where the unit is installed;

- anomaly in mains voltage;

- faulty operation of condenser fan. Device reset is automatic.

2 Ice forms on the evaporator preventing air from flowing regularly.

Possible causes are:

- the door is opened too frequently;

- faulty operation of evaporator fan;

- faulty solenoid valve (in models with hot gas defrost);

- faulty defrost heater (in models with electric defrost);

- faulty defrost process. In this case some measures can be taken: increase defrost termination temperature by some degrees, increase number of defrosts.

ATTENTION Do not use either hot water or any pointed, cutting, metal objects to remove ice blocks.

3. Display does not light up. Check:

- if there is power to the unit;

- if mains cable is connected properly;

- fuses inside the electric panel

4. Unit does not start operating when pressing ON/OFF key (the display is turned on): check microdoor connection keeping in mind that the switch contact must be closed when the door is closed.

Unsatisfactory efficiency of the unit:

If no defects are found in the unit check that: cold room doors are perfectly tight; there is no cold dispersion; the cold room is used wisely; no unfrozen liquids or foodstuffs are placed in the low temperature room; the evaporator is ice-free. We recommend installation of the machines far from the doors especially when the cold room is expected to be opened many times a day.

WARNING:

Removal of protections during machine operation is absolutely forbidden. They have been developed to safeguard the operator’s safety.
