To provide drainage
▪ Make sure that condensation water can be evacuated properly.
▪ Install the unit on a base to make sure that there is proper
drainage in order to avoid ice accumulation.
▪ Prepare a water drainage channel around the foundation to drain
waste water away from the unit.
▪ Avoid drain water flowing over the footpath, so that it does NOT
become slippery in case of ambient freezing temperatures.
▪ If you install the unit on a frame, install a waterproof plate within
150 mm of the bottom side of the unit in order to prevent water
from getting into the unit and to avoid drain water dripping (see the
following figure).
INFORMATION
If necessary, you can use a drain pan (field supply) to
prevent drain water from dripping.
NOTICE
If the unit CANNOT be installed fully level, always make
sure that the inclination is towards the backside of the unit.
This is required to guarantee proper drainage.
NOTICE
If drain holes of the outdoor unit are covered by a mounting
base or by floor surface, raise the unit to provide a free
space of more than 150 mm under the outdoor unit.

Snow
In regions with snowfall, snow might build up and freeze between the
heat exchanger and the casing of the unit. This might decrease the
operating efficiency. To prevent this:
1
Remove the beam structure (see figure below).

Remove the knockout hole (a) by tapping on the attachment
points with a flat head screwdriver and a hammer.
