How to install a split system air conditioner
Select an unobstructed location on your interior wall to mount the indoor air conditioning unit.
Avoid direct sunlight and heat sources. Avoid locations where gas may leak or where oil mist or sulphur exists.
The indoor unit requires at least 6 " (15 cm) of open space surrounding its top and sides. The unit should also be mounted at least 7 feet (2.13 m) above the ground.
