4.2 Starting the chiller
• Connect the power supply to the machine by turning the main
isolator switch QS [P0] to ON.
• Turn the chiller ‘ON’ by pressing the key [P1].
• Set the desired temperature on the controller.
Phases Monitor
If appears on display the alarm “PI1/PI2 “, 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
(7°C) with a differential of 7.2°F (4 °C); to adopt a new setting, see
eading 4.5.
b) 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 = 29 PSIg (2 bar)
pump data plate values: Pmin 14PSIg(1 bar)/ Pmax 43PSIg (3 bar)
adjust the valve outlet to give a pressure of
43PSIg (3 bar) < P1< 72PSIg (5 bar)
- Example n°2.
Conditions:
open circuit, pressure P0 = 0 PSIg (0 bar)
pump data plate values: Pmin 14PSIg(1 bar)/ Pmax 43PSIg (3 bar)
adjust the valve outlet to give a pressure of
Pmin 14PSIg(1 bar)/ Pmax 43PSIg (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 (5 °C) and that the ambient temperature in which the
hydraulic circuit operates does not fall below 41°F (5 °C). If the
temperature is too low, add the appropriate quantity of glycol, as
explained under heading 3.3.2
4.3 Stopping the chiller
When chiller operation is no longer required, turn the chiller off as fol-
lows: press key [P2] to switch the controller ‘Off’.
Do not turn off the main switch QS [P0] to ensure that any antifreeze
protection 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.
