2-3. INDOOR UNIT PREPARATION
Remove the front panel of the indoor unit.
1) Push the 2 locations marked “PUSH” on the upper part of the front grille until a “click”
is heard.
2) Open the front grille toward you.
3) Remove the 2 screws.
4) Grasp the rear horizontal vane at the upper air outlet, and open it.
5) Push the 3 locations on the top of the front panel, and then pull the upper part of the
front panel toward you.
6) Remove the front panel while lifting it up (slightly).
* The front panel can be removed without opening the damper of the lower air outlet.
*
Do not open the damper
of the lower air outlet.

2-4. INDOOR UNIT INSTALLATION
• Hook the top of the indoor unit on the indoor unit mounting bracket (7).
• Use the included wood screws (9) and washer (10), and fasten the indoor unit at 2
locations( ) each at the top and the middle of the unit.
2-5. 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 tem-
perature 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.
