Assembling the outdoor unit
Mount the outside component on a suitable support or wall with adequate load capacity.
The wall bracket WKS 357 is available as an accessory.
• The inflow and outflow of air must be unimpeded.
• An air short circuit must be avoided.
• Minimum clearances must be observed.
• Distances to bedrooms and third-party rooms should be selected as large as possible to avoid annoying noise.

Condensate drainage in the outdoor unit
During heating operation there is a formation of condensate which must be drained.
There is a hole (diam. 25) for condensate drainage in the base plate of the outdoor unit into which the condensate drainage plug
supplied can be inserted.
If the installation situation permits this, the condensate formed can drip down from the bottom side of the outdoor unit; otherwise
drainage must be provided by connecting a hose.
Caution!
• If possible, the drain house should not be fixed.
• If a condensate hose is is installed, it must always slope downwards.
The condensate may possibly freeze when heating below temperatures of +4 °C.
This may block the fan.
If temperatures below +4°C are to be expected at the condensate outlet during heating operation, appropriate measures, e.g.
insulation (insulation of the base of the casing and the condensate drainage area) should be taken.
Sealing the wall opening
This is not done until the outdoor unit has been installed and all necessary connections between the indoor and the outdoor unit
have been made.
The wall openings must be closed in a correct manner.
In the case of fire protection walls, the relevant regulations must be complied with.
