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 remote control unit will be splashed with water or affected by dampness or humidity.
•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.
•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.

• Heat sources, exhaust fans. | EG |
•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.
