Installation site selection - Indoor unit
AVOID
• Direct sunlight.
• Nearby heat sources that may affect unit performance.
• Areas where leakage of flammable gas may be expected.
• Locations where large amounts of oil mist may occur
(such as in kitchen or near factory equipment) because
oil contamination can cause operation problems and may
deform plastic surfaces and parts of the unit.
• Unsteady locations that will cause noise or possible water
leakage.
• Locations where the indoor unit and the remote control unit
will be splashed with water or affected by dampness or
humidity (i.e. in laundries).
• To make holes in areas where electrical wiring or conduits
are located.
DO
• Select an appropriate position from which every corner of
the room can be uniformily cooled.

WITH ADDITIONAL REFRIGERANT (m)
• Select a sufficiently strong location to support the weight
of the unit.
• Select a location where tubing and drain hose have the
shortest run to the outside.
• Allow access for operation and maintenance as well as
unrestricted air flow around the unit.
Installation site selection - Outdoor unit
AVOID
• Heat sources, exhaust fans.
• Direct sunlight.
• Damp, humid or uneven locations.
• To make holes in areas where electrical wiring or conduits
are located.
DO
• Choose places as cool as possible and well ventilated.
• use lug bolts or equal to bolt down the unit, reducing
vibration and noise.
