Safety instructions

- Only recognised, qualified contractors may carry out the
electrical work and installation of the heating circuit.
- Work on the refrigerant circuit must only be carried out by
a recognised and qualified refrigeration engineer or by our
customer service engineer.
- The qualified contractor is responsible for adherence
to all applicable regulations during installation and
commissioning.
- The appliance should only be operated once it is fully in-
stalled and all safety equipment has been fitted.
- Protect the appliance from dust and dirt during building
work.
WARNING Injury
!
The appliance may be used by children over 8 years of
age and persons with reduced physical, sensory or men-
tal capabilities or a lack of experience and expertise,
provided that they are supervised or they have been
instructed on how to use the appliance safely and have
understood the potential risks. Children must never play
with the appliance. Children must never clean the ap-
pliance or perform user maintenance unless they are
supervised.
WARNING Injury
!
f For safety reasons, only operate the appliance with f
the casing closed.
WARNING Injury
The system contains refrigerant. Refrigerant is heavier
than air. If refrigerant escapes from the appliance, it
sinks and displaces the air. There is risk of suffocation.
f Install the appliance only in rooms with adequate f
ventilation.
WARNING Injury
In conjunction with naked flames, refrigerant forms a
toxic irritant gas. The gas can already be smelt at con-
centrations well below the permissible limit values.
f Leave the room until it has been adequately venti- f
lated.

Appliance description

The appliance is a heating heat pump suitable for operation as a
brine | water heat pump. The heat pump extracts energy from the
heat source medium at a low temperature level. This extracted
energy is then transferred to the heating water at a higher level,
augmented by the electric energy drawn by the compressor. Sub-
ject to the heat source temperature, heating water can be heated
up to a flow temperature of 65 °C.
If a DHW cylinder is integrated in the system, the appliance can
be used to heat DHW. To heat the DHW, the heating water that
has been heated by the heat pump is directed through an indirect
coil in the DHW cylinder, where it transfers its energy to the DHW.
An electric threaded immersion heater can be installed in the
buffer and DHW cylinder for use as a booster heater (see chapter
"Installation / Appliance description / Accessories / Additional
accessories"). An external, second heat generator can also be
integrated in the system as a booster heater.
The optional Internet Service Gateway ISG accessory allows the
system to be monitored via the internet.
4. Operation
The heat pump is exclusively controlled via the programming unit.
Observe the instructions for the programming unit.

Maintenance and care

Material losses
!
Only qualified contractors may perform maintenance
work, such as electrical safety checks.
A damp cloth is sufficient for cleaning all plastic and sheet metal
parts. Never use abrasive or corrosive cleaning agents.
We recommend regular inspection (to establish the current con-
dition of the system), and maintenance by a qualified contractor
if required (to return the system to its original condition).
