Deciding where to install the outdoor unit
  If the outdoor unit is installed at a height, ensure that its base is firmly fixed
in position.
  Make sure that the water dripping from the drain hose runs away correctly
and safely.
Outdoor Unit
  The outdoor unit must not be placed on its side or upside down, as the
compressor lubrication oil will run into the cooling circuit and seriously
damage the unit.
  Choose a location that is dry and sunny, but not exposed to direct sunlight
or strong winds.
  Do not block any passageways or thoroughfares.
  Choose a location where the noise of the air conditioner when running and
the discharged air do not disturb any neighbours.
  Choose a position that enables the pipes and cables to be easily connected
to the indoor unit.
  Install the outdoor unit on a flat, stable surface that can support its weight
and does not generate any unnecessary noise and vibration.
  Position the outdoor unit so that the air flow is directed towards the open
area.
  Maintain sufficient clearance around the outdoor unit, especially from a
radio, computer, stereo system, etc.
