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 pres-
sure and any pressure drops expected to occur in the pipework.
Technical regulations for domestic water installation are to be ob-
served. The nominal pipe widths for the on-site sanitary installa-
tion must be determined taking into account the building-specific
requirements and the valid directives and regulations. Any nec-
essary safety devices, such as pressure reducing valves, must
be installed according to the specific requirements.
Both rigid and flexible water pipes may be used. Observe the cor-
rosion 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 conden-
sate 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 con-
trol external devices, e.g. the 2nd heat generator, solar circulat-
ing 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 diagram Cap. 3 on
page V and the electrical documentation.

5.4 Connection air duct

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