(11) ECONO COOL (
) operation (ECONOmical operation)
When ECONO COOL button is pressed in COOL mode, set temperature is automatically set 2°C higher than that in
COOL mode.
Also the horizontal vane swings in various cycle according to the temperature of indoor heat exchanger(indoor coil ther-
mistor).
SWING operation makes you feel cooler than set temperature. So, even though the set temperature is higher than that
in COOL mode, the air conditioner can keep comfort. As a result, energy can be saved.
ECONO COOL operation is cancelled when ECONO COOL button is pressed once again or VANE CONTROL
button is pressed or change to other operation mode.
(10) 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.

• 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 will inclease for the room temperature to reach the
set temperature.
