STARTING UP
STARTING OPERATION
Before starting the unit, turn the main switch on, select the
operating mode desired from the control panel and press the
“ON” button on the control panel.
If the unit fails to start up, check if the service
thermostat has been set according to the nominal
values provided
You should not disconnect the unit from
the power supply during periods when it
is inoperative but only when it is to be
taken out of service for a prolonged
period (e.g. at the end of the season). To
turn off the unit temporarily follow the
directions provided in the section 4.5.
CHECKS DURING OPERATION
-
Check the phase sequence relay on the control board to
verify whether the phases occur in the correct sequence:
if they do not, disconnect the unit from power supply and
invert two phases of the incoming three-pole cable.
Never
attempt to modify internal electrical connections: any
undue modifications will immediately invalidate the
warranty.
-
Check that the temperature of the water entering the
evaporator is close to the value set on the service
thermostat.
