3-23. When Installing the Indoor Unit
Confirm that the indoor unit should be installed in a horizontal position.
Use the level gauge or vinyl tube and check every four corner of the
unit is in horizontal.
If the air outlet duct flange is positioned with downward gradient,
there is in danger of water splash or drainage.
Also, dust may sometimes be contaminated inside the drain pan caused
by the residual drain water.
Install the air outlet duct flange side in horizontal or upward and within the
range of 10mm in the upward direction.
Never install it with a downward gradient against horizontal.

3-24. Required Minimum Space for Installation and Service
If the ceiling tiles cannot be removed, provide the opening holes on the
lower side of the indoor unit for removing the unit in order to maintain
and clean the drain pan and heat exchanger or provide a minimum of
300mm or more space.
