Description of the unit
The SPO series includes air-cooled or water-cooled (optional) condensing units built in split version. They
consist of:

Operation
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.
SPO 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.

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.
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 make the packed unit oscillate dangerously and possibly
fall.
