SPECIAL INFORMATION
SPECIAL INFORMATION
- The appliance may be used by children aged8
and older and persons with reduced physical,
sensory or mental capabilities or a lack of ex-
perience and know-how, provided that they are
supervised or they have been instructed on how
to use the appliance safely and have understood
the resulting risks. Children must never play with
the appliance. Children must never clean the ap-
pliance or perform user maintenance unless they
are supervised.
- The connection to the power supply must be in
the form of a permanent connection. Ensure the
appliance can be separated from the power sup-
ply by an isolator that disconnects all poles with
at least 3mm contact separation.
- Maintain the minimum clearances to ensure trou-
ble-free operation of the appliance and facilitate
maintenance work.
- Maintenance work, such as checking the electri-
cal safety, must only be carried out by a qualified
contractor.
- We recommend an annual inspection (to establish
the current condition of the system), and main-
tenance by a qualified contractor if required (to
return the system to its original condition).
- Never interrupt the power supply, even outside
the heating season. The system's active frost pro-
tection is not guaranteed if the power supply is
interrupted.
- The heat pump manager automatically switches
the heat pump to summer or winter mode.
- If the heat pump and frost protection are com-
pletely switched off, drain the system on the
water side.
