CAUTION! Risk of damage!
Connecting the inlet pipe outside the marked areas (Fig. 6) can lead to leakage, func-
tional impairment and damage to the system.

• Measure position. Pay attention to the minimum connection height for the inlet in the tank
and the perpendicular entry into the tank (90° ± 5°). The horizontal notch lines in the tank
provide orientation for the connection heights 180 mm and 250 mm (pipe centre). Other
infinitely variable connection heights are possible.
NOTE: Inlet ports below 180 mm are possible, but can cause a corresponding backflow in
the inlet pipe. In this case, when the pump run-time is set low, there is the danger that the
pipe no longer empties completely due to the low water level drop in the tank, which can
cause deposits to form inside it (see 8.2.2 Setting the pump run-time).
• Select the position and pipe installation so that surge-like water entry and strong air entry
are avoided as much as possible.
CAUTION! Risk of malfunctions!
Surge-like water ingress can impair the function of the unit. Connect the inlet pipe so
that the entering water flow does not hit the float of the level control directly.
