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)

If appears on display the alarm " ", during the start up, the user
must verify the wiring of the input terminals of the disconnecting
switch.
4.2.1 Adjustments at commissioning
a) The chiller is set for operation at a default temperature of 44,6 °F
with a differential of 7,2 °F; 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 running
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 41 °F and that the ambient temperature in which the hydraulic
circuit operates does not fall below 41°F. If the temperature is too
low, add the appropriate quantity of glycol, as explained under
heading 3.3.2
Y
ATTENTION !: before switching on the chiller pump, close the
water outlet valve.
Always keep the possible inlet valve open, if present.
After switching on the pump, slowly open the chiller water outlet
valve and adjust the fl ow rate as described in point 4.2.1.

4.3 Stopping the chiller

When chiller operation is no longer required, turn the chiller off as fol-
lows: press the button "SET" (5 sec.).
Do not turn off the main switch QS to ensure that any antifreeze protec-
tion devices will still receive electrical power

4.4 Parameter settings

General
There 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).
