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.
EG
• 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
