Assembly

The KWL compact unit is suitable for "hanging", for wall installation and therefore intended for installation
within a residential/room unit.
in an ancillary room (washroom, hall, utility room, storeroom). Ensure that there is a wastewater
connection in the installation area.
Installation should take place in such a way to enable preferably short ventilation ducts and their trouble-
free connection to the unit. Tight bends can lead to increased pressure loss and flow noise.
Important note:
1. Terminal box accessible on the left side of right-hand unit versions, on the right side of left-hand
unit versions.
2. If a pre-heater or auxiliary heater is installed, the duct must be at least 1 m before and after the
heater battery from non-flammable material (see functional layout Fig.17).
3. The heater must be installed in such a way that the electric box is easily accessible.
4. In order to avoid sound transmissions, a suitable acoustic insulation must be planned on site
depending upon the structure.
5. When installing the KWL compact unit, a sufficiently accessible revision area must be provided.
6. The installation of the KWL compact unit is permitted only in frost-protected areas, since the
danger of freezing exists. The ambient temperature may not drop below +5 °C!

Wall installation

In order to mount the unit to the wall, the minimum height of 300 mm
ventilation unit must be observed to ensure a proper condensation outlet (see Fig. below)!
1. Mount the pre-assembled mounting rails horizontally to the wall (Fig.4). Then screw down the wall rail
(in scope of delivery) to the bottom of the rear panel of the compact unit (Fig.5).
2. Hang the compact unit on the mounting rail. The top mounting rail on the rear panel of the KWL unit is
pre-assembled (Fig.6).
Then screw the unit to the wall with the wall mounting rail (Fig.7).
Ensure that the unit is mounted to the wall on both wall rails!
Due to the operating noise, it is recommended that the KWL unit is installed
Please consider the information in section 2.2 "condensation outlet"!
