Description
The unit you bought is an “air cooled chiller”, a machine aimed
to cool water (or water-glycol mixture) within the limits
described in the following. The unit operazion is based on
vapour compression, condensation and evaporation according
to reverse Carnot cycle.The main components are:
- Screw compressor to rise the refrigerant vapour pressure
from evaporation pressure to condensation pressure
- Evaporator, where the low pressure liquid reqrigerant
evaporates so cooling the water
- Condenser, where high pressure vapour condensate
rejecting heat removed from the chilled water in the
atmosphere thanks to an air cooled heat exchanger.
- Expansion valve allowing to reduced the pressure of
condensed liquid from coinsensation pressue to
evaporation pressure
General Information
All units are delivered with wiring diagrams, certified
drawings, nameplate; and DOC (Declaration Of
Conformity); these documents show all technical data
for the unit you have bought and they MUST BE
CONSIDERED ESSENTIAL DOCUMENTS OF THIS
MANUAL
In case of any discrepancy between this manual and the

Immediately report the damage to the manufacturer
representative, a set of photographs are helpful in recognizing
responsibility
Damage must not be repaired before the inspection of the
transportation company representative.
Before installing the unit, check that the model and power
supply voltage shown on the nameplate are correct.
Responsibility for any damage after acceptance of the unit
cannot be attributed to the manufacturer.
Operating limits
Storing
Environmental conditions must be within the following limits:
Minimum ambient temperature : -20°C
Maximum ambient temperature : 57°C
Maximum R.H. : 95% not condensing
Storing below the minimum temperature may cause damage to
components. Storing above the maximum temperature causes
opening of safety valves. Storing in condensing atmosphere
may damage electronic components.
Operation
Operation is allowed within the limits mentioned in Figure 2.
The unit must be operated with an evaporator water flow rate
between 50% and 140% of nominal flow rate (at standard
operating conditions).
Operation out of the mentioned limits may damage the unit.
In case of doubts contact manufacturer representative.
