Placing The Unit Inside The Ceiling - Sanyo SPW-X483GH56 Installation Instruction

3-11.

Placing the Unit Inside the Ceiling

(1) When placing the unit inside the ceiling, deter-
mine the pitch of the suspension bolts using the
supplied full-scale installation diagram.
(Fig. 3-36)
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 posi-
tion 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 ceiling of more
than 60 mm as shown in Fig. 3-36.
(3) Thread the 2 hexagonal nuts and washers (field
supply) onto the 4 suspension bolts as shown in
Fig. 3-37.
Use 2 sets of nuts and washers (upper and
lower), so that the unit will not fall off the
suspension lugs.
(4) Remove the protective cardboard used to protect
the fan parts during transport.
(5) Adjust the distance between the unit and surface
of the ceiling (48 mm) using the supplied
installation gauge. (Fig. 3-36)
