1) Select the best location
1. Indoor unit
■ Do not have any heat or steam near the unit.
■ Select a place where there are no obstacles in front of the unit.
■ Make sure that condensation drainage can be conveniently
routed away.
Do not install near a doorway.
■ Ensure that the space around the left and right of the unit is
more than "A". The unit should be installed as high on the wall
as possible, allowing a minimum of "B" from ceiling.
■ Use a stud finder to locate studs to prevent unnecessary dam-
age to the wall.
2. Outdoor unit
■ If an awning is built over the unit to prevent direct sunlight or
rain exposure, make sure that heat radiation from the con-
denser is not restricted.
■ Ensure that the space around the back and sides is more
than 10cm. The front of the unit should have more than
70cm of space.
■ Do not place animals and plants in the path of the warm air.
■ Take the air conditioner weight into account and select a
place where noise and vibration are minimum.
■ Select a place so that the warm air and noise from the air
conditioner do not disturb neighbors.
Install the indoor unit on the wall where the height from
the floors more than 2.3 meters.

■ Consult local codes regarding rooftop mounting.
