1.1 Important notes
ATTENTION!
Read these installation and operating instructions before
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 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 manu-
facturer. Any other use beyond that intended by the manufac-
turer is prohibited. This requires the user to abide by the rele-
vant project planning documents. Please refrain from
tampering with or altering the device.
1.3 Regulations / safety
information
ATTENTION!
Read these installation and operating instructions before
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 flu-
ids other than domestic water is not permitted. Technical
regulations for domestic water installation are to be ob-
served. The nominal pipe widths for the on-site sanitary in-
stallation must be determined taking into account the
building-specific requirements and the valid directives and
regulations. Any necessary safety devices, such as pres-
sure reducing valves, must be installed according to the
specific requirements.
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 aero-
-
sols
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 EU 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 con-
tains the fluorinated refrigerant R134a included in the
Kyoto protocol. Information on the GWP value and CO
equivalent of the refrigerant can be found in the chapter
Device information. The refrigerant is CFC-free, non-ozone
depleting and non-combustible.
