Condensing water
In the heating season, the extract air humidity condenses to water. In new buildings, condensation runoff can form rapidly. Condensed water must be able to freely leave the unit.
Some condensing water may have accumulated in the bottom pool of the unit; this is normal and requires no corrective action.
At some time before the heating season begins (e.g. during autumn maintenance), check that the siphon or the condensing water outlet in the bottom pool are not clogged. To check this, pour some water into the pool. Clean as required.
Water must at all times be kept out of the electrical system.
Removal of condensing water in the summer
In certain, quite rare, indoor and outdoor air conditions, condensing water may accumulate at the bottom pool of the unit if the cold recovery has been activated (switched on by default). This may happen, for example, if it is particularly hot and humid outside and noticeably cooler inside.
If excess water accumulates at the bottom, remove the orange plug (T) from the condensing water outlet.
