1) Selection of 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 conve-
niently 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 unneces-
sary damage to the wall.
2. Outdoor unit
• If an awning is built over the unit to prevent direct sun-
light 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 minimum.
• Select a place so that the warm air and noise from the
air conditioner do not disturb neighbors.
