▪ 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).
NOTICE
Cold climates. If the unit is installed in a cold climate:
▪
Take adequate measures so that the evacuated condensate CANNOT freeze.
▪
Do NOT use the drain plug and drain hose with the outdoor unit. Possible
consequence: Drain water might freeze, decreasing the heating capacity.
NOTICE
Provide at least 300 mm of free space below the unit. Additionally, make sure the
unit is positioned at least 100 mm above the expected level of snow.
Except in cold climates, use the drain plug and a hose for drainage.
