3-9. 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.

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. 3-33. 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. 3-36. 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.

(5)Adjust so that the distance between the bottom of the indoor unit suspension lugs and the bottom of the ceiling panel is 25/32 – 1 in. Then tighten the nuts above and below each suspension lug. The full-size installation diagram can be used to help adjust the height of the indoor unit.
