(d) Installation procedure
1) Mount the duct for the air inlet grille to the indoor unit
using the 10 tapping screws provided. The tapping screws
on the drain pan receiver side are also used for mounting
the duct for the air inlet grille. They must first be removed
and reinstalled after the duct for the air inlet grille is in
place. A guideline for the height is to secure the assembly
so that the lower surface of the duct for the intake grille is
approximately 10 mm above the bottom surface of the
ceiling.
2) Remove the center screw for the air inlet grille and open
the grille as shown in the illustration. Next, insert the air
inlet grille into the duct for the air inlet grille and secure it
with the pan-head screws (the long screws).
3) Use the pan-head screws to make the small adjustments
in height. The height dimension on the installation dia-
gram allows for adjustment within range of 80 to 100 mm.
If the pan-head screws are completely tightened, the height
will be 80 mm.
