Assembly

The KWL compact unit is suitable for "hanging", for wall installation and therefore intended for installation within a resi-
dential/room unit. Due to operating noises which change according to system pressure, it is recommended to install the
KWL unit in the washing room, utility rooms or storerooms. Ensure that there is a waste water connection in the instal-
lation area. Please consider the information in section 2.2 "condensation outlet"!
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. The ventilation pipes must never be kinked.
The attachment to the connection spigots must be firm and tight. With regard to maintenance and installation work, the
unit and the internal terminal box must be freely accessible.
Important note:
1 . The terminal box is only accessible by removing the heat exchanger, open the front cover beforehand .
2 . If an additional external heater battery is installed, the duct must be at least 0 .5 m before and after the heater
battery from non-flammable material (see functional layout Fig .24) .
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 free-
zing 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 must be observed to ensure a proper
condensation outlet (see Fig. below)

1. Mount the pre-assembled mounting rails horizontally to the wall (Fig.3/4).
2. In order to reduce the weight, remove the enthalpy heat exchanger from the unit (Fig.5).
In this respect, also observe section 3.1.
