Handling
W AR NI NG
M ake sure that no one is in transit in the operating area of the lifting/ transport m eans to
prevent any possible accidents to people.
I f the unit is in a w ooden case or crate, sling the packing properly before handling it.
Lifting speed shall be such as not to m ake the packed unit oscillate dangerously and
possibly fall.
The AS series includes air-cooled or water-cooled (optional) condensing units built
on the basis of the single-block principle. They consist of:
1. an evaporator installed inside the cold room;
2. an insulating panel;
3. a condensing unit placed outside the cold room;
4. an electric control panel placed on the condensing unit.
AS 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);
manual defrost is also possible.
The unit can be handled by lifting and transport means.
