▪ 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).
NOTICE
If the unit is installed in a cold climate, take adequate measures so that the
evacuated condensate CANNOT freeze. We recommend to do the following:
▪ Insulate the drain hose.
▪ Install a drain tube heater (field supply). To connect the drain tube heater, see
"9.2.1To connect the electrical wiring to the outdoor unit"[4105].
NOTICE
Provide at least 150mm of free space below the unit. Additionally, make sure the
unit is positioned at least 100mm above the expected level of snow.
Use the drain plug (with O-ring) and a hose for drainage.
