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.
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.
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.
The unit can be handled by lifting and transport means.
