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 a proper
drainage in order to avoid ice accumulation.
▪ Prepare a water drainage channel around the foundation to drain
waste water surrounding 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 the
invasion of water in the unit and to avoid the drain water dripping
(see the following illustration).
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.
