Oxygen diffusion
Material losses
!
Avoid open vented heating systems and underfloor
heating systems with plastic pipes that are permeable
to oxygen.
In underfloor heating systems with plastic pipes that are per-
meable to oxygen and in open vented heating systems, oxygen
diffusion may lead to corrosion on the steel components of the
heating system (e.g. on the indirect coil of the DHW cylinder, on
buffer cylinders, steel radiators or steel pipes).
Material losses
!
The products of corrosion (e.g. rusty sludge) can set-
tle in the heating system components, which may re-
sult in a lower output or fault shutdowns due to reduced
cross-sections.
Supply lines
f The maximum permissible line length between the appli-
ance and the heat pump will vary, depending on the version
of the heating system (pressure drop). As a standard value,
assume a maximum line length of 10 m and a pipe diameter
of 22-28 mm.
f Protect the flow and return lines against frost with sufficient
thermal insulation.
f Also protect all supply lines against humidity, damage and
UV radiation by means of a conduit.
f Connect the hydraulic connections with flat gaskets.
Pressure differential
If the available external pressure difference is exceeded, the pres-
sure drop in the heating system could result in a reduced heating
output.
f When sizing the pipes, ensure that the available external
pressure differential is not exceeded (see chapter "Specifica-
tion / Data table").
f When calculating the pressure drop, take account of the flow
and return lines and the pressure drop of the heat pump.
The pressure drop must be covered by the available pressure
differential.

11.3.2 Heating water connection
Installation example:
1 Pipes carrying heating water
f Thoroughly flush the pipes before connecting the heat pump.
Foreign bodies (e.g. welding pearls, rust, sand, sealant, etc.)
can impair the operational reliability of the heat pump.
f Install the heating water pipes (see chapter "Specification /
Dimensions and connections").
Safety valve drain hose
1 Safety valve drain hose
f Unroll the safety valve drain hose connected to the multi-
function assembly.
f On one of the lower prepared openings on the left or right,
remove just enough insulating material as necessary for the
drain hose, in order to minimise the exchange of air.
f Route the drain hose through the prepared opening from the
appliance.
f Route the drain hose with a constant fall to a drain.
f Ensure that the drain hose is open to the outside.
f Secure the drain hose above the drain to prevent any hose
movement in the event of water being discharged.
Material losses
!
Route the drain hose to a drain to enable water to drain
freely when the safety valve is open.
