Assembly

The KWL compact unit is suitable for "hanging", for ceiling installation and therefore intended for installation within
a residential/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 installation area. Please consider the information on the "condensation outlet"! Assembly 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. The ventilation ducts must not become kinked.
2. The connections to the connection valves must be firm and tight.
3. The terminal box is connected to the side of the casing and must be easily accessible for maintenance and installa-
tion work.
4. If an external heater is connected, there must be at least 1 m piping before and after the heater, which must be made
of non-flammable material (see function diagram Fig. 9).
5. The heater must be installed in such a way that the electrical box is easily accessible.
6. In order to prevents sound transmission, appropriate acoustic decoupling must be provided on site depending on
the building material.
7. The assembly of the KWL compact unit must only take place in rooms that are free of frost, as there is a
danger of freezing. The room temperature must not fall below +5 °C!

DANGER TO LIFE! Before installing the compact unit, it must be ensured that the ceiling and/or the fixing
components used can withstand the heavy weight and vibration of the KWL EC.. unit. Unsuitable mounting
material can lead to the unit falling uncontrollably from the ceiling. There is danger to life due to the heavy
weight! Furthermore, it can also lead to a large amount of property damage!
Depending on the mounting, a further safeguard must be implemented to safeguard the KWL compact unit
from falling uncontrollably!
Four mounting brackets including rubber buffers (Fig.1) are mounted to the unit for ceiling installation. Installation to the
ceiling takes place e.g. with hanger bolts (Fig. 2) or suitable mounting accessories.
When installing to ceiling, it is recommended that the heat exchanger is removed from the unit to reduce the ins-
tallation weight when lifting.
In order to guarantee the proper outlet of condensate water, it must be ensured that the ventilation unit is
installed with a lateral incline of 3° in the direction of the condensation outlet (Fig. 4); refer to label next to the
condensation outlet on the unit.
