Fit the fi lter valve
The task of the particle fi lter is to fi lter out dirt before it can enter the
heat pump. Accordingly, the supplied fi lter valve should always be fi tted
on the return pipe on the hot side, between the HWDU and the outdoor
heat pump. It should be fi tted as close to the heat pump as possible and be
horizontal.
