Installation position
The outdoor unit must be located in a dry and well ventilated outdoor space on a supporting
structure that is flat, horizontal, and can withstand the full operating weight of the unit. The base
must be free of vibration.
Locate the outdoor unit as close as possible to the indoor unit to reduce performance losses. The
refrigerant pipe length or height, or height difference between outdoor and indoor does not exceed
the maximum allowable limits, refer p.18.
Select a location where the unit will not be subject to accumulation of snow, leaves or other
seasonal debris. This may negatively impact the performance and longevity of the unit. Arrange so
the air outlet is not blocked or obstructed.
In addition:
• Position so as to prevent operating noise being a nuisance to others
• Away from potential fire risks or flammable materials
• If possible, away from exposure to direct sunlight as this will negatively impact cooling
performance
DO NOT install in the following locations:
• Near an obstacle that will block air inlets and outlets
• Near a public street, crowded areas, or where noise will disturb others
• Near animals or plants that will be harmed by hot air discharge
• Near any source of combustible gas
• In a location that is exposed to large amounts of dust
• In a location exposed to excessive amounts of salty air
Special considerations for heavy wind exposure
For installations prone or exposed to strong prevailing
winds such as coastal areas, please ensure the unit is
sited appropriately by placing it lengthwise along the
wall to reduce any negative impact on the condenser
fans. Install the unit so that the air outlet fan is at a
90° angle to the direction of the wind. If needed build
a barrier in front of the unit to protect it from extremely
heavy winds.
