When the air-water heat pump is not used for a long period of
time, the following operations are to be performed:
Press the Standby A tile on the touch screen interface.
Turn the master switch of the device to the 0-OFF position.
After having deactivated the unit:
Deactivate the internal terminal units by turning the switch
of each unit to “off”.
Turn the system master switch to “off”.
Close the water taps.
If the outside temperature could fall below zero and there is a
risk of freezing, the hydraulic system MUST BE EMPTIED, or else
antifreeze (e.g. ethylene glycol) must be added in the dosage
recommended by the producer of the liquid.
To re-start the air-water heat pump after a long period of stop
and inactivity, request an intervention of the Technical Service
If a boiler is present in the system, check during operation that
the temperature of the water circulating in the air-water heat
pump does not exceed 65 °C.

discharged freely because it is polluting.

3 .6 Cleaning
The only cleaning operation required on behalf of the person re-
sponsible for the system is the external brushing of the air-water

with water and soap.
For persistent stains, use a solution of 50% denatured alcohol in
water or a specific product.
When the cleaning is completed carefully dry the surfaces.
Do not use sponges with abrasive products or powder de-
tergents.
Always disconnect the device from the electrical mains by
turning the master switch of the system to the “off” position
before starting any cleaning operation.
