6.2 Condensate pipe
Condensed water that forms during operation must be drained
off frost free. To ensure proper drainage, the heat pump must be
mounted horizontally. The condensate pipe must have a mini-
mum diameter of 50 mm and must be fed into a sewer in such a
way that it is safe from frost. Do not discharge the condensate di-
rectly into clearing tanks or cess pits. The aggressive vapours
and a condensate pipe laid in an area which is not frost-free can
destroy the evaporator.
ATTENTION!
The frost line can vary according to the climatic region. The regulations
of the countries in question must be observed.
7 Installation
7.1 General
The following connections need to be established on the heat
pump:
Flow and return of the brine (heat source system)
Heating system flows and returns
Condensate drain
Control cable to the heat pump manager
Power supply
7.2 Connection on heating side
Refer to the device information for the connection sizes.
A spanner must be used to firmly grip the transitions when con-
necting the heat pump.
ATTENTION!
Flush the heating system prior to connecting the heat pump.
Before connecting the heating water system to the heat pump,
the heating system must be flushed to remove any impurities,
residue from sealants, etc. Any accumulation of deposits in the
liquefier may cause the heat pump to completely break down.
Once the heat pump has been connected to the heating system,
it must be filled, purged and pressure-tested.
ATTENTION!
The maximum test pressure in the heating circuit and the brine circuit is
6.0 bar.
This value must not be exceeded.
The following points must be observed when filling the system:
Untreated filling water and make-up water must be of drink-
ing water quality
(colourless, clear, free of sediments)
Filling water and make-up water must be pre-filtered (max.
pore size 5 µm).
Scale formation in domestic hot water heating systems cannot be
completely avoided, but in systems with flow temperatures below
60 °C, the problem can be disregarded.
With medium and high temperature heating systems, even tem-
peratures above 60 °C can be reached.
The following standard values should therefore be adhered to re-
garding the filling and make-up water according to VDI 2035,
sheet 1:
Use of the optionally available 4-way reversing valve is recom-
mended. A detailed installation description can be found in the in-
structions included with the valve.
Note:
For operation of the heat pump with the four-way reversing valve,
it is essential to set up the hydraulic connections according to the
instructions included in the scope of supply of the valve. These
instructions describe the procedure for setting up the correct hy-
draulics in more detail. Non-observance of this will lead to restric-
tions in the operation of the heat pump.
Important:
The notes/settings in the instructions of the heat pump manager
must always be observed and carried out accordingly; not doing
so will lead to malfunctions.
