Wiring The Receiver Unit - Sanyo Big PACi 18 Series Technical Data & Service Manual

●
When using a receiver that has been installed separately into the ceiling,use the enclosed fittings
for installing to a ceiling.
(1) Remove the metal plate of the receiver by slipping a flathead screwdriver or the like into the
cutout on the bottom.
(2) Cut out a hole in the ceiling to match the dimensions of the enclosed template. (95 X 51 mm)
(3) Pass the wiring through the enclosed installation metal fitting and put it into the hole. (Fig. 8-20)
(4) Bend parts A and B of the metal fitting so they hold onto the ceiling firmly. (Fig. 8-21)
(5) Connect the receiver's wiring (2 cores) with the wiring from the indoor unit. (Refer to "8-17.
Wiring the Receiver Unit".) When wiring receivers, be sure to double-check the terminal num-
bers of the indoor unit before connecting them so there are no mistakes in the wiring. (Damage
will occur if high voltage [e.g. supply voltage] is applied.)
(6) Adjust the enclosed spacers so they are several millimeters thicker than the ceiling material
and hold the receiver in place temporarily with the 2 enclosed machine screws. (M4 X 40)
(7) Bend parts A and B back so they fit in the opening and are in the gap between the surface of
the ceiling and the receiver; then tighten the screws. Do not use too much force when tighten-
ing the screws. Doing so may warp or damage the case. Move the receiver by hand and check
that it can move just a little. (Fig. 8-22)
(8) Attach the face plate.

Use remote control cord (sold separately) for wiring a separately installed receiver.
(1) For instructions on how to install a remote control cord (sold separately), refer to the chapter on Using as an
Embedded Model in Installing Separate Receivers.
(2) If a remote control cord (sold separately) is to be used, refer to the Mounting Instructions attached to the remote
control cord.

1. When wiring remote controls, be sure to double-check the terminal numbers of the indoor unit connecting them
so there are no mistakes in the wiring. (Damage will occur if high voltage [e.g. supply voltage] is applied.)
2. If the wiring to the operation panel is bundled together with other wiring, such as the incoming line from the
power source, it can cause a malfunction, so avoid doing so.
3. If something causes the unit's power source to make noise it will be necessary to resolve the problem, such as
by installing a noise filter.

(Field supply)
1. Strip the wire to be connected of its sheathing for 14 mm.
2. Twist the two wires together and crimp the enclosed wire joint.
3. If a special crimping tool is not used, or if the connection is made using solder,
wrap the joint with insulating tape.
