NOTICE
To prevent damage to the supporting feet, do NOT tilt the
unit sideways in any way:
6.3.5
To provide drainage
▪ Avoid installation places where water leaking from the unit due to
a blocked drain pan can cause damage to the location.
▪ 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.
▪ When the unit is in cooling mode, condensate may also form in
the hydro part. When providing drainage, therefore make sure to
cover the entire unit.
▪ 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 the unit is installed in a cold climate, take adequate
measures so that the evacuated condensate cannot
freeze.
INFORMATION
For information on the available options, contact your
dealer.
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.

To prevent the outdoor unit from falling
over
In case the unit is installed in places where strong wind can tilt the
unit, take following measure:
1
Prepare 2 cables as indicated in the following illustration (field
supply).
2
Place the 2 cables over the outdoor unit.
3
Insert a rubber sheet between the cables and the outdoor unit
to prevent the cable from scratching the paint (field supply).
