7. Remote Control Unit Installation Position
The remote control unit can be operated from either a
non-fixed position or a wall-mounted position.
To ensure that the air conditioner operates correctly, do
not install the remote control unit in the following places:
● In direct sunlight
● Behind a curtain or other place where it is covered
● More than 26' (8 m) away from the air conditioner
● In the path of the air conditioner’s airstream
● Where it may become extremely hot or cold
● Where it may be subject to electrical or magnetic
interference
● Where there is an obstacle between the remote con-
trol unit and the air conditioner (since a check signal
is sent from the remote control unit every 5 minutes)
7-1. Mounting on a Wall
Before mounting the remote control unit, press the
ON/OFF operation button at the mounting location to
make sure that the air conditioner operates from that
location. The indoor unit should make a beeping sound
to indicate that it has received the signal.
