The downpipe must go into a sufficiently large gravel
bed so that the condensate can trickle away freely.
NOTE
To prevent the condensate from freezing,
self-regulating heating cable(field supply) must
be threaded into the downpipe so that the
condensate can discharge via the downpipe.

5.5 In cold climates

It is recommended that the unit be placed with the rear
side against the wall.
Install a lateral canopy on top of the unit to prevent lateral
snowfall in extreme weather conditions.
Install a high pedestal or wall mount the unit to keep a
proper clearance (at least 100 mm) between the unit and
snow.
① Canopy or alike
② Pedestal in case of installation on a ground
If there is a risk of snow slip from the roof,
protective roof or cover must be erected to protect the
heat pump, pipes and wiring.

5.6 Exposure to Strong Sunlight

Long time of exposure of the ambient temperature
sensor of the unit to sunlight might impact the sensor
negatively, and cause undesirable impacts on the unit.
Shade the unit with a canopy or alike.
