► Before commencing work on electrical connections
and installation, the heat pump system must be isolat-
ed and voltage-free.
► The appliance may not be used as a step or platform.
Do not climb on the appliance or place any loads on
it.
WARNING: Injury
The appliance may be used by children aged 8 and
up and persons with reduced physical, sensory or
mental capabilities or a lack of experience provided
that they are supervised or that they have been
instructed on how to use the appliance safely and

not be allowed to play with the appliance. Children
must not be allowed to clean or carry out user
maintenance on the appliance without supervision.
3. Appliance description
The appliance is a brine/water heat pump consisting of
an indoor unit and a brine circuit (geothermal collectors,
geothermal probe). The appliance can be used to heat a
building and provide domestic hot water (DHW).
3.1 Functionality
The brine/water heat pump extracts thermal energy from
the ground (low temperature) and transmits it together with
electrical drive energy in the form of useful heat (higher
temperature) to a heating and/or DHW circuit.
The heat pump generally works in monovalent heating
mode. The heat pump can be combined with other heat
generators.
The heat pump consists of separated circuits linked togeth-
er via heat exchangers:
► Heat source circuit (brine circuit with geothermal col-
lectors or geothermal probe)
► Refrigerant circuit
► Heat sink circuit (supply of heat to the central heating
and/or DHW)

3.2.1 Indoor unit
The indoor unit is intended to be installed only inside the
building. The indoor unit contains the compressor, which
in terms of sound technology is acoustically decoupled a
