CONDENSING WATER (USER)
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.
At some time before the heating season begins (e.g. during
autumn maintenance), check that the water seal or the
condensing water outlet in the bottom pool are not clogged.
To check this, pour some water into the pool. Clean as
required.
