Panasonic R410A Specifications, Suspending the Indoor Unit, It is important that you use, Fig

6-23. Suspending the Indoor Unit

Depending on the ceiling type:

•Insert suspension bolts as shown in Fig. 1-69 or

•Use existing ceiling supports or construct a suitable support as shown in Fig. 1-70.

WARNING	It is important that you use
	extreme care in supporting the
	indoor unit inside 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.

(1)When placing the unit inside the ceiling,

1determine the pitch of the suspension bolts referring to the dimensional data on the previous page. (Fig. 1-68)

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

(2)Screw in the suspension bolts allowing them to protrude from the ceiling as shown in Fig. 1-69. (Cut the ceiling material, if necessary.)

(3)Thread the 2 hexagonal nuts and washers (field supply) onto the 4 suspension bolts as shown in Figs. 1-71 and 1-72. Use 2 sets of nuts and wash- ers (upper and lower), so that the unit will not fall off the suspension lugs.
