Care and maintenance
Regular care and maintenance serves to ensure
trouble-free operation and long service-life of the
heat pump system.
Care
n
The indoor and outdoor units must be kept free
of soiling, vegetation and other deposits.
n
The device is to be cleaned with a damp cloth.
In doing so, it is to be ensured that no caustic,
abrasive or solvent-based cleaning products
are used. Use of powerful water jets is to be
avoided.
n
The fins on the outdoor unit are to be cleaned
at least once a year.
Maintenance
n
To perform the possibly statutory seal test, it is
necessary to arrange an annual maintenance
contract with an appropriate specialist firm.
NOTICE!
As the refrigerant capacity exceeds 3 kg, an
annual seal inspection must be made of the
refrigerant circuit by a firm specializing in this
field. A heating system should always be serv-
iced annually. Therefore, we recommend
arranging for a service contract that includes
the seal inspection.

Temporary shut-down
The system may not be switched off at the mains
power supply even if the heating system is not
used for heating purposes over an extended period
(e.g. holidays)!
n
The system is to be switched to "Stand-by"
mode during temporary shut-down periods.
n
Heating phases can be programmed for the
duration of the period of absence.
n
The previous operating mode has to be
switched back on when the shut-down phase
is over.
n
Instructions for changing the mode appear in
the corresponding chapter of the heat-pump
manager's manual.
NOTICE!
In "Standby" , the heat pump is in standby
mode. Of the entire system, only the frost-pro-
tection function s activated.
