for mounting. Drill two horizontal holes Ø 6
mm at a distance of 168 mm apart (Stan-
dard) or 254 mm apart (Comfort). Screw the
2 rounded head screws 4.5 x 35 mm (TX20)
in as far as necessary for the control unit to
be mounted flush to the wall. Make sure
there is enough distance from the wall on
the right to allow the cover to be opened.
The screws, plastic dowels and drilling tem-

Then insert the pump plug (grey, Fig. 1)
and the sensor plug (white, Fig. 2) in the
control unit according to the markings (en-
larged views) and tighten (3 Nm for pump
connection / 1 Nm for probe connection).

2.3 Probe/motor installation

The optical probe for the pump (red) is mo-
unted in the cover on the inlet side. For this
purpose, the blind plug (lilac) is removed
and the probe is screwed in place hand-tight
using the enclosed screws (2 M5 x 12 scr-
ews TX25 (see Fig. 6).
The same procedure applies for the optical
probe for the motor (black, Fig. 7). However,
this is mounted in the outlet cover – opposi-
te the motor.
