Installation
4.1
Installation position
The 3-way switching valves can be installed either vertically or

The 3-way switching valves may not be installed sus-
pended, i.e. with the tappet facing down.
Permissible installation positions
90°
4.2
Hydraulic connection
Beware of damage
!
The conditions in VDI 2035 regarding water quality must
be complied with. So that the 3-way switching valve con-
trols the flow for a long time, we recommend the use of
contamination filters.
Beware of damage
!
Make sure the ball is correctly positioned in
the 3-way switching valve (note the mark on
the spindle).
Note
As well as the flow direction A – AB and B – AB which
is marked with an arrow on the housing, the opposite
direction AB – A and AB – B is also permitted in STIEBEL
ELTRON or Tecalor heat pump systems.
