4.2 Starting the chiller

• Connect the power supply to the machine by turning the main
isolator switch QS to ON.
set
• Press the button " " to start up.
• Set the desired temperature on the controller. (par. 4.5.1)
4.2.1 Adjustments at commissioning
a) Th e chiller is set for operation at a default temperature of 12 °C with
a diff erential of 3 °C; to adopt a new setting, see heading 4.5.
b) Regolation of th pump (only for water version)
Verify correct operation of the pump, using the pressure gauge (read
P1 and P0) and checking the pressure limit values (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 run-
ning conditions.
Check also that the amperage of the pump is within the limits indi-
cated 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 temperature is too
low, add the appropriate quantity of glycol, as explained under head-
ing 3.3.2

4.3 Stopping the chiller

When chiller operation is no longer required, turn the chiller off as fol-
lows: turn the On/Off [S1] switch to Off .
Do not turn off the main switch QS to ensure that any antifreeze pro-
tection devices will still receive electrical power

4.4 Parameter settings

General
Th ere are two levels of protection for parameters:
a) Direct (D): with immediate access, User-changeable;
b) Password protected (U): password required for access; Factory-set
parameters.(do not change).
