■4-Way Air Discharge Semi-Concealed Type (XM Type)

3-8. Preparation for Suspending

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

that the unit is level.

3-9. 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. 3-29)

(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. 3-30)

3-10. Placing the Unit Inside the Ceiling

(1) When placing the unit inside the ceiling, determine

the pitch of the suspension bolts using the supplied

full-scale installation diagram. (Fig. 3-31)

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.

(2) 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" as shown in

the diagram. (Fig. 3-31)

Over 19/32"

33/64" – 45/64"

(3) Thread the 3 hexagonal nuts and 2 washers (field

supply) 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 suspen-

sion lugs. (Fig. 3-32)

(4) Adjust so that the distance between the unit and the

ceiling bottom is 33/64" to 45/64". Tighten the nuts

on the upper side and lower side of the suspension

lug. (Fig. 3-32)
