(iv) Installation method
1) Attach a duct set onto an indoor unit with 10 tapping
screws. The tapping screws on the drain-pan support side
are designed to fasten a drain-pan support together, so
unscrew the 5 screws from a drain-pan support and fasten
the duct sat and the drain-pan support together. As a rule
of thumb in determining installation height, make the
bottom of a duct set for the air inlet grille stay about
10mm above the ceiling's lower face.
2) Unscrew the air inlet grille's central screw and leave the
air inlet grille in an open state as illustrated in Figure 2.
Then, insert the air inlet grille to a duct for it and fix them
with small pan-head screws (long ones).
3) Small pan-head screws are also used to make a fine
adjustment of installation height. The height measurements
(80 - 100mm) shown in Figure 1 are possible adjustment
ranges, When a small pan-head screw is fastened to the
end, the height will become 80mm.
