the unit must be grounded.
When Transporting
Be careful when picking up and moving the indoor and out-
door units. Get a partner to help, and bend your knees when
lifting to reduce strain on your back. Sharp edges or thin alu-
minum 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 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 floors.
Keep the fire alarm and the air
outlet at least 1.5 m away from
the unit.
When Connecting Refrigerant Tubing

contact of the refrigerant gas with a flame as this will
cause the generation of poisonous gas.

refrigeration circuit other than the designated refrigerant
(R410A). Adding anything other than the specified refrig-

refrigeration circuit, rupturing the circuit and causing injury
or damage.
