Installation locations

WARNING
Risk of injury!
If the installation location does not have a sufficient strength or is not
carried out correctly, the unit may fall leading to serious injury.
▶ Install at a strong and firm location which is able to withstand the
unit's weight.
Before installing the outdoor unit, the following information should be
considered:
• Set up the unit outdoors on a flat stable surface.
• Installing the outdoor unit in a dry and well-ventilated area is
recommended.
• Avoid setting up in locations surrounded by walls.
• Install the outdoor unit in a place as protected as possible from direct
sunlight and with minimum exposure to wind against the front side.
• Consider the sound propagation of the outdoor unit when setting it
up, particularly to avoid noise nuisance to neighbours. Whenever
possible, do not place the outdoor unit in front of rooms or windows.
• Make sure the unit can be always accessed in order to carry out
maintenance work. If access is restricted, e.g. due to the installation
height, suitable measures must be taken to ensure that maintenance
work can still be carried out without additional time expenditure or
costly assembly aids.
• Do not install the outdoor unit in a place that requires treading on light
roofs such as a tiled roof or asbestos. No service will be provided in
this case.
Considerations for installing the outdoor unit at the sea side
The outdoor unit should be placed with a minimum distance to the sea of
500m. In France and Ireland a minimum distance of 1000m is
recommended. It is recommended to place the appliance in a such a way
that the evaporator does not face the sea wind.
NOTICE
Risk of product damage or malfunction!
Short-circuit or corrosion of components.
▶ Avoid installing outdoor unit in damp locations.
▶ The unit should be free from corrosive and moisture surrounding.
Considerations regarding installation in areas with strong wind,
heavy rain and snow:
▶ Install the outdoor unit so that the air flow direction is at 90° angle to
the wind direction. If necessary, build a barrier in front of the unit to
protect it from extremely heavy winds.
▶ Build a shelter above the outdoor unit to protect it from rain or snow.
Be careful not to obstruct the air flow around the unit.
