partner to help, and bend your knees
when lifting to reduce strain on your
back. Sharp edges or thin aluminum
fins on the air conditioner can cut your
fingers.
When Installing…
Select an installation location which is
rigid and strong enough to support or
hold the unit, and select a location for
easy maintenance.
…In a Room
Properly insulate any tubing run inside
a room to prevent “sweating” that can
cause dripping and water damage to
walls and floors.

the air outlet at least
1.5 m away from the unit.
…In Moist or Uneven Locations
Use a raised concrete pad or concrete
blocks to provide a solid, level foundation
for the outdoor unit. This prevents water
damage and abnormal vibration.
…In an Area with High Winds
Securely anchor the outdoor unit down
with bolts and a metal frame. Provide a
suitable air baffle.
…In a Snowy Area (for Heat Pump-
type Systems)
Install the outdoor unit on a raised
platform that is higher than drifting snow.
Provide snow vents.
