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

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 condenser 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 min-
imum.
