3. DESCRIPTION OF THE UNIT
The GM series includes air-cooled or water-cooled (optional) condensing units built on the basis of the
single-block principle. They consist of:
4. OPERATION
5. HANDLING
WARNING
Make sure that no one is in transit in the operating area of the lifting/transport
means to prevent any possible accidents to people.
If the unit is in a wooden case or crate, sling the packing properly before handling it.
Lifting speed shall be such as not to make the packed unit oscillate dangerously
and possibly fall.

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.
