FOR LEFT OR LEFT-REAR PIPING
Bundle the connecting pipes and drain hose together, and then wrap them in felt tape B.
Make sure that the
drain hose is not
routed upward.
Wrap the felt tape B tightly around
the pipes and hose starting near
where the pipes and hose are routed
from the indoor unit. (The overlap
Felt tape B
width of the felt tape B should not be
more than 1/2 of the tape width.)
Cut and use the lower side panels on the left and right sides of the indoor unit as shown below.
Smooth the cut edges of the side panels so that they will not damage the insulation coating.
• For left or right piping

Start wrapping the piping tape D
around the pipes and hose 10 mm
inside the indoor unit.
Fasten the end of the felt tape B with
a bandage stopper.
Installing flush against a wall with molding
Molding
Cut the lower side panels to match the height of the molding.
4-9 EMBEDDING THE INDOOR UNIT IN A WALL
• When installing a grating, use a grating with narrow upper and lower horizontal bars so that the airflow from
the upper and lower air outlets does not contact the bars. If the horizontal bars will block the lower air outlet,
use a stand, etc., to adjust the height of the indoor unit. If the upper or lower air outlet is blocked, the air
conditioner will not be able to cool or warm the room well.
• Do not block the receiver with the grating. Otherwise, the grating will interfere with the remote controller
signal and significantly reduce the distance and area (angle) from which the signals can be received.
• Use a grating with vertical bars, etc., that has at least 75% open area. If the grating has horizontal bars or if
the open area is less than 75%, performance could be reduced.
• When the indoor unit is embedded in a wall (built-in), the time it takes for the room temperature to reach the
set temperature will increase.

EMBEDDED INDOOR UNIT SETTING (MUST BE PERFORMED)
• When embedding the indoor unit in a wall, restrict the movement of the horizontal vane for the upper air outlet
so that it only operates horizontally.
• If this setting is not performed, heat will build up in the wall and the room will not be cooled or warmed
properly.
• Cut the wires on the left and right sides of JRFBL using a pair of nippers, etc., as shown below.

Cut the wires on both ends.
