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 .
4.4 Parameter settings
General
Th ere are two levels of protection for parameters:
a) Direct (F): with immediate access, User-changeable;
b) Password protected (C): password required for access; Factory-set
parameters.

4.5 Parameter management
4.5.1. Temperature setting (see fi g.1)
1. Press button “ B ” (SET); the message “SET” will appear followed by
the set value, blinking.
2. Change the value, using the up and down arrow buttons “ A ” and
“ C ”, then press button “ B ” (SET) to exit and save.
Th e temperature set point has now been changed.
4.5.2. Diff erential setting
1. Press and hold button “ B ” (SET) for more than 5 seconds to access
the menu.
2. Select the parameter “rd” using the “ A ” and “ C ” buttons, then press
button “ B ” (SET) to confi rm.
3. Change the value, using the up and down arrow buttons “ A ” and
“ C ”, then press button “ B ” (SET) to exit and save.
4.5.3. Unit of measure °C/°F
1. Press and hold button “ B ” (SET) for at least 5 seconds to access the
menu.
2. Select the parameter “PS” using the “ A ” and “ C ” buttons, then press
button “ B ” (SET) to confi rm.
3. Write the password using buttons “ A ” and “ C ”, then press button
“ B ” (SET) to confi rm.
4. Select the parameter “/5” using the “ A ” and “ C ” buttons, then press
button “ B ” (SET) to confi rm.
5. Change the value, using the up and down arrow buttons “ A ” and
“ C ” (0 = °C; 1 = °F)
6. Press and hold button “ B ” (SET) to exit and save the setting.
!
CAUTION: Type “C” parameters are factory set. Consequent-
ly, any change to these parameters (apart from “rd”) could jeopar-
dize the correct operation of the machine.

4.7 Automatic restart
In the event of a power failure, when power is restored the chiller will
assume the On-Off status held at the moment the power was lost.
