11.3.2 Heating water connection
Installation example:
1 Pipes carrying heating water
f Thoroughly flush the pipes before connecting the heat pump.
f
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 /
f
Dimensions and connections").
Safety valve drain hose
1 Safety valve drain hose
f Unroll the safety valve drain hose connected to the multi-
f
function assembly.
f On one of the lower prepared openings on the left or right,
f
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
f
appliance.
f Route the drain hose with a constant fall to a drain.
f
f Ensure that the drain hose is open to the outside.
f
f Secure the drain hose above the drain to prevent any hose
f
movement in the event of water being discharged.

ed (see chapter "Specification / Data table").
Material losses
!
Operate the appliance only with pressure-tested taps.
Note
The use of non-return valves in the charging circuits be-
tween the heat generator and the buffer or DHW cylin-
der can impair the function of the integral multifunction
assembly (MFG) and lead to faults in the heating system.
f Only use our standard hydraulic solutions for the
f
installation of the appliances.
