– Installation of ball siphon
The ball siphon is installed in the bottom reservoir of the unit.
1. Open ball siphon, turn the mounting part a 1/4 turn (Fig.11).
2. Plug the mounting part in the condensation outlet from below, until the claw fasteners snap to the sheet edge of the
base plate (Fig.12)
3. Insert locking part and push upwards (Fig.13).
4. Then connect condensation hose DN 12 mm (not included in the delivery) to the hose connector on the siphon hou-
sing and tighten by hand (Fig.14).

5. Connect siphon housing and turn the mounting part a
1/4 turn (Fig.15)
NOTE: Ensure that the floating ball is in the housing!
6. Connect condensation hose DN 12 mm (length max. 1.5
m) to the building drainage system (siphon). The conden-
sation hose from the ball siphon must have a gradient
(not rising), openly dripping into a funnel siphon and must
not be discharged into a closed system (Fig.16/17).
A closed discharge can lead to pressure conditions which
prevent controlled drainage. Furthermore, gases ma
escape from the drainage line into the unit, which may
create a breeding ground for harmful substances in com-
bination with moisture.
7. The ball siphon must undergo a regular cleaning cycle
(maintenance interval as well as filter maintenance).
– In order to guarantee the absence of leaks, the ball siphon must not be subjected to lateral loads due to
the condensation hose during installation!
– The drainage pipe route must not rise behind the siphon! Ensure that there are no air pockets during ins-
tallation!
– The condensation outlet must be frost-proof!
– The condensate hose must end 20 mm above the open outlet or possible water level!
