● When using the signal receiving unit on a wall with
the front exposed, choose a wall surface that the
signal receiving unit can be mounted on.
(1) Insert a flat tip (minus) screwdriver into the slot on
the lower side of the signal receiving unit and pry
off the back case as shown in Fig. 7-14.
(2) The wire rooting at the signal receiving unit
comes out of the upper case (thin portion at
upper center) so use nippers or a similar tool to
cut out a notch beforehand large enough for the
remote control cable (option) to pass through as
shown in Fig. 7-15.
(3) Remove the wire which is connected prior ship-
ping from the connector.
(4)
Connect the remote control cable (option) to the
signal receiving unit connector shown in Fig. 7-16
after the clamper (supplied) with the unit is installed.
(5) After arranging the wiring on the printed circuit
board as shown in Fig. 7-17 so that it is contained
within the signal receiving unit, attach the back
case. At this time, arrange so that the head of the
clamper faces the side.
(6) Remove the cover plate and install the signal
receiving unit using the 2 wood screws.
(7) Fasten to the wall using the cord clip (supplied).
(8) Reinstall the cover plate.
● To use the signal receiving unit while mounted on a
ceiling, install by using the carrier for ceiling instal-
lation supplied with the unit.
(1) Remove the cover plate by inserting a flat tip
(minus) screwdriver or similar tool into the notch
in the lower section and prying it off.
(2) Cut out a section (3-3/4 × 2-1/32 in.) on the
ceiling using the paper pattern (supplied) as a
guide.
(3)
Run the wire through the mounting carrier and insert
into the installation hole as shown in Fig. 7-19.
(4) Fit securely into the ceiling material at sections
(A) and (B) as shown in Fig. 7-20.
(5) Connect the wire (2-wire core) from the signal
receiving unit with the wire from the indoor unit.
(See section on how to wire the receiving unit.) as
shown in Fig. 7-20.
(6) Use the supplied spacers to adjust for a thickness
several inches more than the ceiling material and
lightly fasten the receiving unit in place with the
small screws (M4 × 1-9/16 in., 2 pcs.) supplied
with the unit.
(7) Tighten the machine screws after fitting sections
(A) and (B) into the openings, in the gap between
the signal receiving unit and ceiling surface as in
Fig. 7-21. Do not apply strong force when tighten-
ing the screws. Excessive force might warp or
damage the cover. When finished the signal
receiving unit should still be able to move slightly
when pressed as shown in Fig. 7-21.
(8) Reinstall the cover plate.
