2 .3 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
outlet in the bottom reservoir.
– Summer cooling
The outside air temperature is sometimes distinctly war-
mer than the room temperature in the summer, and this
tempe rature difference is particularly high in properties
with air conditioning. The cooler room extract air can be
used to slightly cool the warm outside air down by means
of the “summer cooling” function, and this takes place
in the heat exchanger. In this respect, condensation
water can accumulate on the supply air side, and the plug
(Fig. 7) must be removed in this respect.
If the plug (red) is not removed, this can lead to water
damage!
The summer cooling function can be activated via

– 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 hou-
sing and tighten by hand (Fig.11).
