3. Insert locking part and insert up to stop (Fig. 29).
4. Then insert the condensate hose (DN 12 mm; not included in delivery) in the hose connector on the siphon casing
and tighten by hand (Fig. 30).
5. Connect siphon casing and turn a 1/4 turn in the mounting part (see Fig. 31). Ensure that the float ball is loose in
the casing!
Water damage in the unit due to condensation.
A closed discharge can lead to pressure conditions which prevent controlled drainage from the unit. Furthermo-
re, gases may escape from the drainage line into the unit, which may create a breeding ground for microorga-
nisms in combination with moisture.
> The condensate hose must end 20 mm above the open drain or possible water level (see Fig. 32).
> The condensate hose from the ball siphon must have a downward gradient, openly dripping into a funnel
siphon and must not be discharged into a closed system (see Fig. 32).
6. Connect condensate hose (length max. 1.5 m) to the building drainage system (see Fig. 33).
7. The ball siphon must be inspected:
– In order to guarantee the absence of leaks, the ball siphon must not be subjected to lateral loads due to the con-
densate hose during installation!
– The drainage pipe route must not rise behind the siphon! Ensure that there are no air pockets during installation!
– The condensate outlet must be frost-proof!
