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.
