(6) Cautions for wireless remote conntroller operation
As wireless remote controller is operated by infrared rays as a signal, make sure to explain to customers the following matters
regarding the operating distance and protection from jamming.
¡ Operate it by directing the remote controller switch correctly to the receiver amp section.
¡ Operating distance is shown below, but it may become shorter or longer depending on circumstances.
¡ When its receiving section is directly under the sun or strong illumination, or covered by dust or behind an obstacle, the
operating distance may become shorter or it may not work.
¡ A hook for fixing the remote controller is provided for to keep the controller
from missing.
(a) Operating distance of wireless remote controller
Operate it within the distance and angle shown in the sketch.
1) Standard receiving distance
CONDITION:
300 luxes at the receiving section (at an ordinary office where
there is no ceiling light within one meter around the unit.
2) The receiving distance as viewd from the plane, and the rela-
tion between the illumination at the receiving section and re-
ceiving distance.
CONDITION:
The relation between illumination and receiving distance when
the remote controller is operated at the place one meter above
the floor with the ceiling 2.4 m high. When the illumination is
doubled, the receiving distance become 2.3.
By switching the dip switch (SW3-3) on the indoor unit printed circuit board ("Specify the following switch number."), the operation
mode can be changed to the quiet mode (mild mode). Confirm at installation and change if necessary.
6.5.2 Installation of the wired remote controller (Optional parts)
(1) Selection of installation location
Following locations should be avoided:
(a) Where exposed to direct sunlight
(b) Near the heat source
(c) Highly humid area or where splashed with water
(d) Uneven installation surface
(2) Selection of installation location
Exposed installation
(a) Remove the remote controller case.
● Insert finger nails between the upper (white) and lower
(brown) cases and ply them to open.

(b) Remote controller cords can be taken out upward only as
shown below.
● Cut the remote controller lower case off at the top and thin
section with a nipper, knife or other and remove burrs from
the cut with a file or other.
(c) Secure the remote controller lower case on the wall with 2
pieces of wood-screws.

(d) Connect the remote controller cords with the terminal block.
Make sure to align the terminal numbers on the indoor unit
and the remote controller. Polarities are specified on the ter-
minal block so that the unit will not be operated if the cords
are connected improperly.
Terminals: (X) red wire, (Y) white wire, (Z) black wire
