Installation and operating instructions

Compact wall-mounted units KWL EC 200/300 W R/L

CHAPTER 2

INSTALLATION

2.0

Assembly

The KWL compact unit is suitable for “hanging”, for wall 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 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.

IMPORTANT

☞

Important note:

1. Terminal box is accessible on the left side for the right-hand version, and on the right side for

the left-hand version.

2. If an additional external heater battery is installed, the duct must be at least 1 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.

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!

2.1

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).

ATTENTION

2. In order to reduce the weight, remove the cross counter flow heat exchanger from the unit (Fig.5). In

this respect, also observe section 3.1.

The KWL unit is heavy!

3. Mount the compact unit to the mounting rail with the brackets integrated on the back of the KWL unit

(Fig.6).

ATTENTION

It must be guaranteed that the KWL unit is mounted to the wall!
