SHUTTING DOWN FOR LONG PERIODS
A
After deactivating the heat pump:
- Disconnect the unit from the power supply.
- Make sure the remote keypad is in the “OFF” position.
- Place QF1 in the OFF position (see wiring diagram).
- Deactivate the indoor terminal units by placing the switch
of each unit in the “OFF” position.
- Close the water valves.
If the outside temperature may fall below zero; there is
the risk of freezing.
The water circuit MUST BE EMPTIED AND CLOSED (if
draining after operation in heat pump mode, beware that
the water may be hot), or antifreeze must be added in
the proportion recommended by the manufacturer.
It is recommended to use non-toxic food grade
antifreeze, compliant with the standards in force in the
countries where the unit is used, if domestic hot water
production is also featured.
If the mains switch is turned to “off” for more than four
hours, after turning it on and before reactivating the unit,
leave the power on but the unit deactivated for at least
two hours to preheat the oil in the compressor sump.
