Condensation outlet

During the heating period, the humidity of the extract air condenses to water. In new buildings or while having a bath or
sauna as well as with laundry-drying, plenty of condensate can be formed. The condensation must be able to run off
freely from the unit. In this respect, the enclosed ball siphon (included in delivery) must be fitted in the condensation out-
let in the bottom reservoir.
– 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.8).
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.9)
3. Insert locking part and push upwards (Fig.10).
4. Then connect condensation hose DN 12 mm (not included in the delivery) to the hose connector on the siphon
housing and tighten by hand (Fig.11).

5. Connect siphon housing and turn the mounting part a 1/4 turn (Fig.12)
(NOTE: Ensure that the floating ball is in the housing!)
6. Connect the condensation hose DN 12 mm (length as required) to the drainage system
on the housing (siphon). In doing so, position the condensation hose at a gradient
(Fig.13). Absolutely necessary for proper condensation outlet
An open outlet should be installed (diagram Fig.14) due to odour development from
the dried-up siphon.
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!
– The condensation outlet must be frost-proof!
