Loosen the mounting base cover using the two hexagon socket screws.
1. Open ball siphon. Turn the mounting part a 1/4 turn (see ).
2. Plug the mounting part in the condensate outlet from below, until the claw fasteners snap to the sheet edge of the
base plate (see ).
3. Insert locking part and insert up to stop (see Fig. 8).
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 (see Fig. 9).
5. Connect siphon casing and turn a 1/4 turn in the mounting part (see Fig. 10). 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.
> 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.
