• You must have 0.78inch(20mm) or more space between the ceiling and the bottom of indoor unit. Otherwise, the noise
from the vibration of indoor unit may bother the user. When the ceiling is under construction, the hole for check-up
must be made to take service, clean and repair the unit.
• It is possible to install the unit at an height of between 7.54ft~8.20ft(2.2~2.5m) from the ground, if the unit has a duct
with a well defined lenght [11.81inch(300mm)], to avoid fan motor blower contact.
