Condensate removal

During the heating period the humidity of the extract air condenses to water. When bathing, while having a sauna as well
as with drying the laundry or with new buildings, condensate can richly build up. The condensation must be able to run
off freely from the unit. Make sure that the condensation connection or the extension hose is pushed correctly into the
external facia and that the condensate can run off freely (decline of 0,5 % to outside wall, fig. 5).

Filter change

In order to change the filters, two screws of the indoor facia must be removed. Lifting the snaper above and remove
the facia. Take out both air filters (fig. 13, a) and insert the new air filters in the ventilation unit (fig. 13, a).

5 .2 Cleaning – Maintenance
All work must be carried out with the equipment fully isolated from the power supply!
Danger by electrical impact, mobile parts (fan) and hot surfaces.
– Filter
The KWL EC 60 Eco is supplied with filters of class G4 in the supply and extract air stream
(according to DIN EN 1946, T.2)
• Supply air / Extract air
Spare filter pre-filter G4
Spare filter pollen filter F7
The supply and/or extract air filter is to be controlled regularly (see display of speed controller, factory setting every
6 months) depending upon the degree of pollution (danger of mould build up) and to be cleaned if necessary. The filters
can be cleaned once by vacuum cleaning. They should be replaced, however, at the latest after one year for hygienic
reasons.
If the filters should be damp or mouldy, these must be changed immediately!
