1-Way Air Discharge Semi-Concealed Type (A Type) 3-14. Suspending the Indoor Unit

(1)Follow the diagrams to make the holes in the ceiling. (Figs. 3-52 and 3-53)

(2)Depending on the ceiling type:

Insert suspension bolts as shown in Fig. 3-54 or

Use existing ceiling supports or construct a suitable

Asupport as shown in Fig. 3-55.

Make sure that the length of suspension bolts from the bottom of the unit is 19/32 in. or more. (Fig. 3-56)

WARNING

It is important that you use extreme care in supporting the indoor unit from the ceiling. Ensure that the ceiling is strong enough to support the weight of the unit. Before hanging the unit, test the strength of each attached suspension bolt.

(3)Calculate the suspension bolt pitch using the full- size installation diagram (printed on the package). The relationship between the positions of the suspension lugs, unit, and ceiling panel is as shown in Fig. 3-53.

(4)Cut the ceiling material, if necessary. (Figs. 3-52 and 3-53)

If the system requires fresh air to be drawn into the unit, cut and remove the insulation (both externally and internally) at the location shown as A in Figs. 3-57 and 3-58.

CAUTION

When making the cuts to the insulation, be careful not to damage the drain pan.
