<Louver swing range setting (Individual louver control setting)>
It is possible to change the swing range of the louver by the wired remote control. Once the upper and lower limit
positions are set, the louver will swing within the set range.It is also possible to set the different range to each louver.
<Draft prevention setting>
The draft prevention function will not be operated if the draft prevention panel is installed and its wirings are only connected.
To operate the draft prevention function, enable the draft prevention setting by using the wired or wireless remote control.
Note: It is not possible to set by the following remote control models or older.
Wired:RC-EX3, RC-E5, RCH-E3
Wireless: RCN-E1R
Once you have enabled the settings in this mode, the draft prevention function is operated when the air-
conditioner is
started, and the parts of the draft prevention mechanism are always open when the air-conditioner is operating.
When the air-conditioner is stopped, they are closed. It is possible to enabled or disabled the draft prevention
function for each air outlet.
For the setting details, refer to the user’s manual supplied with the remote control.

Installing the panel
1. Temporary hanging
Lift up the hanger (2 places) on the panel for temporary support.
Hang the panel on the hook on the indoor unit.
2. Fix the panel on the indoor unit
Fasten the panel on the indoor unit with the 4 bolts supplied with the panel.
Caution
Air leakage
Air leakage along
the ceiling
Fouling
Dew condensation or dripping
Make sure no gap is left here.
Caution
Do not give any stress on the panel when adjusting the height of the indoor unit to
avoid unexpected distortion. It may cause the distortion of panel or failing to close the
inlet grille, and the parts of the draft prevention mechanism.

Caution
If there is a gap between the ceiling and the
panel even after the xing bolts are
tightened, adjust the installation level of the
indoor unit again.
Improperly tightened xing bolts cause the
problems listed below, so make sure that bolts
are securely tightened.
Be careful not to pinch the motion sensor wiring.
The panel and the inlet grille have no directional limitation to install. (Hinges of the inlet grille can be hooked at any side.)
Install the inlet grille in the reverse order of the steps described at .
1 Attach the fall grille hook to the panel.
2 Insert the hinges of inlet grille in the insert holes on the panel.
Close then the inlet grille while pressing the stoppers (2 places).
Conrm that both stoppers are inserted securely in the panel.
6
Orientation of the panel installation
Take note that there is an orientation to install the panel.
Install the panel with the orientation shown on the right.
CAUTION
Align the “PIPE SIDE” mark (on the panel) with the
refrigerant pipes on the indoor unit.
Align the “DRAIN” mark (on the panel) with the drain
pipe on the indoor unit.
In case the orientation of the panel is
not correct, it will lead to air leakage
and also it is not possible to connect
the motor wiring.

Checking the indoor unit installation height
Pull the corner lid toward the direction indicated by the arrow and remove it. (Same way for all 4 corner lids)
Read this manual together with the indoor unit’s installation manual.
Fasten the wiring to the terminal securely and hold the cable securely so as not to apply
unexpected stress on the terminal.
Loose connection or hold will cause abnormal heat generation or fire.
Make sure the power supply is turned off when electric wiring work.
Otherwise, electric shock, malfunction and improper running may occur.
Read this manual together with the air conditioner installation manual carefully.
Check if the opening size for the indoor unit is correct with the level gauge supplied in the indoor unit.
Check if the gap between the plane and the indoor unit is correct by inserting the level gauge into the air outlet
port of the indoor unit. (See below drawing)
Adjust the installation elevation if necessary.
Remove the level gauge before installing the panel.
If there is a height difference beyond the design limit between the installation level of the indoor unit and the
panel, the panel may be subject to excessive stress during installation and it may cause distortion and damage.
