4.2 Starting the chiller
4.2.1 Compressor heating
• Connect the power supply to the machine by turning the
main isolator switch QS [P0] to ON.
(Only for L2 option:
BE ACTIVATED 24 HOURS BEFORE STARTING THE MA-
CHINE).
Incorrect operation can damage the compressor.
• Switch the chiller ON as shown in the fi gure.
• Set the desired temperature on the controller.

4.2.2 Adjustments at commissioning
a) Temperature setting. To adopt a new setting, see heading
4.5.
b) Verify correct operation of the pump, using the pressure
gauge (read P1 and P0) and checking the pressure limit val-
ues (Pmax and Pmin) indicated on the pump data plate.
P1 = pressure with pump ON
P0 = pressure with pump OFF
Pmin < (P1-P0) < Pmax
- Example n°1.
Conditions:
closed circuit, pressure P0 = 2 bar
pump data plate values: Pmin 1 bar/ Pmax 3 bar
adjust the valve outlet to give a pressure of 3 bar < P1< 5
bar
- Example n°2.
Conditions:
open circuit, pressure P0 = 0 bar
pump data plate values: Pmin 1 bar/ Pmax 3 bar
adjust the valve outlet to give a pressure of 1 bar < P1 < 3
bar
c) Verify correct operation of the pump similarly under normal
running conditions.
Check also that the amperage of the pump is within the limits
indicated on the data plate.
d) Switch off the chiller and proceed to top up the hydraulic
circuit at the "SET" temperature.
e) Check that the temperature of the "treated" water does not
fall below 5 °C and that the ambient temperature in which the
hydraulic circuit operates does not fall below 5 °C. If the tem-
