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 warmer 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 enthalpy heat
exchanger. In this respect, condensation water can accumulate.
The summer cooling function can be activated via

and, to this end, the plug must also be remo-
ved (Fig. 9/10).
If the plug is not removed, this can lead to water damage!
