6.3.5 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).
