5.1 Connecting the water pipes

The water connections (see dimension drawing (Cap. 1 on
page II)) are located at the rear of the unit.
NOTE
Circulation pipe
For energy efficiency reasons, a circulation pipe should not be
used if this can be avoided. If a circulation pipe is installed in
the domestic hot water distribution system, a valve or a similar
device must be provided as shut-off facility to avoid
unnecessary energy losses. Circulation is enabled according
to use (time or requirement control).
The nominal pipe widths for the on-site sanitary installation
must be determined by taking into account the available water
pressure and any pressure drops expected to occur in the pipe-
work.
Technical regulations for domestic water installation are to be
observed. 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 pressure reducing
valves, must be installed according to the specific require-
ments.
Both rigid and flexible water pipes may be used. Observe the
corrosion behaviour of the pipework materials used in order to
avoid corrosion damage (see "Commissioning" on page 10.).
NOTE
Domestic hot water, cold water and circulation connections:
These pipe nipples contain plastic inserts, the purpose of
which is to provide corrosion protection (in particular to the
pipe nipple flange surfaces). These plastic inserts remain in
their positions after installation.
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).

5.2 Connecting the condensate
pipe
The condensate hose is routed through the cladding at the rear
of the device. It should be routed in such a way that the con-
densate produced (during heat pump operation) can flow away
freely.
There is a pressureless seal valve at the end of the condensate
hose, which must be relocated accordingly if the condensate
hose is shortened (the valve can be easily removed and re-in-
serted). The condensate must be drained off in a siphon (see
cap. 8.1 "Maintenance instruction").
NOTE
The sealing lip valve must be used to prevent damage from
condensate.

5.3 Electrical connection

The domestic hot water heat pump is wired ready for use; the
power supply takes place via the mains power connection,
which is plugged into an earthed wall socket (~230 V, 50 Hz).
This socket must remain accessible after installation. In order to
control external devices, e.g. the 2nd heat generator, solar cir-
culating pump or collector temperature sensor, a separate
cable must be connected to the device via an available cable
gland and strain relieved. Do this by opening the device cover
as described in Cap. 3.5 on page 7. The relevant connection
points of the components can be found in the electrical dia-
gram Cap. 3 on page V and the electrical documentation.

5.4 Connection air duct

The device is designed for connecting an EPP air duct (individ-
ual components available as accessories DN 160 inside). The
90° position of the two connecting stubs means that a wide
range of ducts are possible.
