3-15. Placing the Unit Inside the Ceiling

CAUTION	Be sure to use a level gauge
	and confirm that the unit is
	level. If it is not level, water
	leakage may occur.

(1)Use the supplied M5 or 3/16" screws (4) to attach the full-size installation diagram to the indoor unit suspension lugs, in order to obtain the ceiling opening dimensions for suspending the unit. (Fig. 3-56)

Caution: Piping and wiring work must be performed inside the ceiling after the unit is suspended. Therefore if the ceiling is already installed, the wiring and piping work should be completed up to the connection points prior to suspending the unit.

(2)Attach the special washers (supplied) and nuts (field supply) to the suspension bolts (4 locations).

CAUTION

● Use M10 or 3/8" nuts.

● The length of the suspension bolts must be such that

there is a space of at least 19/32 in. below the bottom

of the suspension lugs, as shown in Fig. 3-56. If the

length of the suspension bolts is too long, the bolts

may interfere with the ceiling panel and louver motor,

preventing their installation.

(3)	Thread the 3 hexagonal nuts and 2 washers (field
	supply) onto each of the 4 suspension bolts as
	shown in Fig. 3-59. Use 1 nut and 1 washer for the
	upper side, and 2 nuts and 1 washer for the lower
	side, so that the unit will not fall off the suspension
	lugs.
(4)	Lift up the indoor unit and fit the suspension bolts
	into the notches in the suspension lugs.
