3. How to Install the Indoor Unit

3-1. Preparation for Suspending

This unit uses a drain pump. Use a carpenter’s level to check that the unit is level.

3-2. Suspending the Indoor Unit

(1)Fix the suspension bolts securely in the ceiling using the method shown in the diagrams, by attaching them to the ceiling support structure, or by any other method that ensures that the unit will be securely and safely suspended. (Fig. 6-1)

(2)Follow the diagram to make the holes in the ceiling.

(3)Determine the pitch of the suspension bolts using the supplied full-scale installation diagram. The dia- gram shows the relationship between the positions of the suspension fitting, unit, and panel. (Fig. 6-2)

3-3. Placing the Unit Inside the Ceiling

(1)Be sure to remove the fan protection (4pcs) for transportation before hanging up the indoor unit.

(2)When placing the unit inside the ceiling, determine the pitch of the suspension bolts using the supplied full-scale installation diagram. (Fig. 6-3)

Tubing and wiring must be laid inside the ceiling when suspending the unit. If the ceiling is already constructed, lay the tubing and wiring into position for connection to the unit before placing the unit inside the ceiling.

(3)The length of suspension bolts must be appropriate for a distance between the bottom of the bolt and the bottom of the unit of more than 19/32" (15 mm) as shown in the diagram. (Fig. 6-3)

(4)Thread the 3 hexagonal nuts (locally purchased) and 2 supplied washers onto each of the 4 suspension bolts as shown in the diagram. 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. (Fig. 6-4)

(5)Adjust so that the distance between the unit and the ceiling bottom is 1/2" (13 mm) to 23/32" (18 mm). Tighten the nuts on the upper side and lower side of the suspension lug. (Fig. 6-4)
