(2) Hanging the Switch Box
(a) Hang the Switch Box by putting hands on the
bottom of the cabinet.
(b) Insert the suspension bolt into the groove
part of the suspension bracket as shown
in Figure 4.5. Ensure that the washers
are correctly affixed to the suspension
bracket.
(c) After the hanging work, the piping and
wiring connection work is required inside
the ceiling in the gap between the roof and
ceiling so it is not visible. Therefore,
determine the drawing direction of the pipe
after selecting the installation location of the
Switch Box. Before doing the hanging
work, carry out the piping and wiring work
up to the connecting positions.
(d) Keep the Switch Box level to the ceiling
surface. If the Switch Box is not level, a
malfunction may occur.
(e) Tighten the nuts of the suspension
bolt with the suspension bracket after
adjustment is completed.
Adhesive must be applied to the nuts in
order to prevent them from loosening.
