▪ 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 150mm 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 150mm under the outdoor unit.
