3 Description of the unit
The GS series includes air-cooled or water-cooled (optional) condensing units built in split
version. They consist of:
1. a condensing unit placed outside the cold room;
2. an evaporator installed inside the cold room;
3. an electric control panel placed on the condensing unit, complete with wall-
mounted remote control panel;
4. two tubes (pre-charged with refrigerant) to be connected to the
corresponding fittings placed on the evaporating and condensing units.
4 Operation
GS 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 means of heaters; manual defrost
is also possible.
5 Handling
The unit can be handled by lifting and transport means.
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.
