1.1 Important notes
ATTENTION!
Read these installation and
commissioning!
ATTENTION!
Work on the domestic hot water heat pump is to be performed by
qualified personnel only! Observe accident prevention regulations!
ATTENTION!
The device cover cannot be used for carrying (the cover cannot withstand
significant forces).
ATTENTION!
Once the heat pump has been set up, the guard plate must be removed!
ATTENTION!
The heat pump must not be transported overhead.
ATTENTION!
When installing the on-site pipework, ensure that the pipes are not
contaminated (flush pipes before connecting the domestic hot water heat
pump if necessary).
ATTENTION!
The domestic hot water heat pump must only be operated when filled with
water.
ATTENTION!
The domestic hot water heat pump must only be operated when filled with
water.
ATTENTION!
The collector sensor must be a temperature sensor with the resistance
characteristic curve of a PT1000 (see Cap. 2.4.2 on pag. 4).
ATTENTION!
Disconnect the power supply before opening the domestic hot water heat
pump; possible fan coasting must be considered.
ATTENTION!
Risk of injury caused by sharp-edged fins. Fins must not be deformed or
damaged!
ATTENTION!
The device must be de-energised before it can be opened.
ATTENTION!
The terminal X8 can also be energized when the heat pump is in switched-
off state
ATTENTION!
For settings for using photovoltaic energy. a solar thermal system or an
external boiler, domestic hot water temperatures of >60°C are possible
and an external scald protection must therefore be in place.

1.2 Intended use
This device is only intended for use as specified by the manufac-
turer. Any other use beyond that intended by the manufacturer is
prohibited. This requires the user to abide by the relevant project
planning documents. Please refrain from tampering with or alter-
ing the device.
1.3 Regulations / safety
information
ATTENTION!
Read these installation and
commissioning!
The domestic hot water heat pump is used exclusively to

heat water for domestic use and drinking water within the
specified operating temperature limits. The heating of fluids
other than domestic water is not permitted. Technical regu-
lations for domestic water installation are to be observed.
The nominal pipe widths for the on-site sanitary installation
must be determined taking into account the building-specific
requirements and the valid directives and regulations. Any
necessary safety devices, such as pressure reducing
valves, must be installed according to the specific require-
ments.
 The following are not permitted:
Operating the pump with solvent-based or explosive ex-
-
haust air
- The use of exhaust air containing grease, dust or aerosols
containing adhesive substances
- The connection of extractor hoods to the
ventilation system
 It is not permissible to install the device:
- Outdoors
- In rooms which are exposed to frost
- In rooms subject to high humidity (e.g. bathrooms)
- In rooms with air which is potentially explosive
due to gases, vapours or dust
 It is not permissible to operate the device:
- With an empty cylinder
- During the construction phase of the building
 The construction and design of the domestic hot water heat
pump complies with the relevant EC directives. (See also
CE declaration of conformity).
 The technician must ensure that the refrigerant is flushed
adequately to allow maintenance and repair work to be car-
ried out on refrigerant circuit components without risk. Re-
frigerant must be properly handled and disposed of; it must
not be released into the environment!
The refrigeration circuit is "hermetically sealed" and contains
the fluorinated refrigerant R134a with a GWP value of 1430,
incorporated in the Kyoto protocol. The refrigerant is CFC-
free, non-ozone depleting and non-combustible.
 Always disconnect the power supply before carrying out any
work on the domestic hot water heat pump.
