When Installing...
...In a Ceiling or Wall
Make sure the ceiling/wall is strong enough to hold the unit’s weight. It may be necessary
to construct a strong wood or metal frame to provide added support.
...In a Room
Properly insulate any tubing run inside a room to prevent “sweating” that can cause
dripping and water damage to walls and
fl
oors.
...In an Area with High Winds
Securely anchor the outdoor unit down with bolts and a metal frame.
Provide a suitable air baf
fl
e.
...In a Snowy Area (for Heat Pump-type Systems)
