To provide drainage
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 150 mm under the outdoor unit.

Snow
In regions with snowfall, snow might build up and freeze between the
heat exchanger and the casing of the unit. This might decrease the
operating efficiency.
INFORMATION
We suggest to install the optional bottom plate heater
(EKBPH250D7) when the unit is installed in cold climates.
