3-15. Placing the Unit Inside the Ceiling
(1) When placing the unit inside the ceiling, determine
the pitch of the suspension bolts using the sup-
plied full-scale installation diagram. (Fig. 3-51)
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 appropri-
ate for a distance between the bottom of the bolt
and the bottom of the unit of more than 15 mm as
shown in Fig. 3-51.
(3) Thread the 3 hexagonal nuts and 2 washers (field
supply) onto each of the 4 suspension bolts as
shown in Fig. 3-52. 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) Adjust so that the distance between the unit and
the ceiling bottom is 12 to 17 mm. Tighten the nuts
on the upper side and lower side of the suspen-
sion lug.
(5) Remove the protective polyethylene used to pro-
tect the fan parts during transport.
