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.
• To place appliances under tension (household appliances,
computers), because in case of emergency operation the unit could
drip condensate water.

DO
• Select an appropriate position from which every corner of the room
can be uniformily cooled.
• Select a sufficiently strong ceiling 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.

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.
