Choosing an Installation Site

• Before choosing the installation site, obtain user approval.

1.

Indoor unit

• The indoor unit should be positioned in a place where:

1) the restrictions on the installation requirements specified in 

“Indoor Unit Installation Diagram”

 on page 4 are met,

2) both the air inlet and air outlet are unobstructed,
3) the unit is not exposed to direct sunlight,
4) Install so that drainage occurs easily,
5) the unit is away from sources of heat or steam,
6) there is no source of machine oil vapor (this may shorten the indoor unit service life),
7) cool/warm air is circulated throughout the room,
8) the unit is away from electronic ignition type fluorescent lamps (inverter or rapid start type) as they may affect the remote 

controller range,

9) no laundry equipment is nearby.

2.

Wireless remote controller

• Turn on all the fluorescent lamps in the room, if any, and find a location where the remote controller signals are properly 

received by the indoor unit (within 23ft (7m)).
