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:
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).
4 Operation 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.
5 Handling The unit can be handled by lifting and transport means.
UNSCREW THE FIXING SCREWS TO REMOVE CRATING FROM THE UNIT. (fig.
A).
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.
