▪ 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).
6.3.6 To prevent the outdoor unit from falling
over
In case the unit is installed in places where strong wind can tilt the
unit, take following measure:

3 Insert a rubber sheet between the cables and the outdoor unit
to prevent the cable from scratching the paint (field supply).
