9.4.2. Temporary installation of the grille (Fig. 9-6)
• Temporarily secure the grille using the bell shaped holes by putting the socket of
the grille marked
G
on the corner drain pipe area of the main unit.
* Make sure that the lead wiring of the grille does not get pinched between the
grille and the main unit.
9.4.3. Securing the grille (Fig. 9-7)
• Secure the grille to the main unit by tightening the previously installed 2 screws
(with captive washer) as well as the 2 remaining screws (with captive washer).
* Make sure that there are no gaps between the main unit and the grille or the
grille and the ceiling.
Fixing gaps between the grille and the ceiling
With the grille attached, adjust the height of the main unit to close the gap.
9.4.4. Wire connection (Fig. 9-8)
• Remove the 2 screws fixing the cover of electrical branch box of the unit and
open the cover.
• Be sure to connect the connector(white, 20-pole) for vane motor of the grille to
CNV connector of contoller board of the unit.
• As for PLP-6BALM(E), the connector of wireless sensor cable is also connected
to connecor CN90 on indoor controller board.
The lead wire of grille is passed through the catch of bell mouth of the unit
perfectly. The remaining lead wire is tied with clamp of the unit and put the cover of
the unit again with 2 screws.
Note:
Do not put the remaining lead wire in electrical branch box of the unit.
.5. Installing the intake grille (Fig. - )
Note:
When reinstalling the corner panels (each with a safety wire attached), con-
nect the other end of each safety wire to the grille using a screw (4 pcs,
4
×
8) as shown in the illustration.
*If the corner panels are not attached, they may fall off while the unit is operating.
• Perform the procedure that is described in “9.2. Preparing to attach the grille” in
reverse order to install the intake grille and the corner panel.
• Multiple units can be installed with grille so that the position of the logo on each
corner panel is consistent with the other units regardless of the orientation of the
intake grille. Align the logo on the panel according to the wishes of the customer
as shown in the diagram to the left. (The position of the grille can be changed.)

* Installation in any position is possible.
G
Initial position of the levers on the intake grille
* Although the clips can be installed in any of 4 positions, the configuration shown
here is recommended.(It is not necessary to remove the intake grille when
maintenance is performed on the electric component box of the main unit.)

.6. Installation of i-see sensor corner panel
(Fig. 9-10)
For PLP-6BAE, PLP-6BAMDE, PLP-6BALME panel
• Take the lead wires CN4Y(white) and CN6Y(red) of the i-see sensor corner panel
9
from the side of the electrical box on the unit and make sure to conect them to
the connector of the controller board.
• Lead wires of the i-see sensor corner panel
9
should be fixed at the rib of the
grille with the fastener
4
so that there is no slack.
• Lead wires should be held together with the lead wires of the unit and fixed with 2
of the fastener
4
so that there is no slack.
• Put the cover back on the electrical box with 3 screws.
* Make sure wires are not caught in the cover of electric box. If they are caught,
they will be cut.
• Adverse procedure of “9.2. Preparing to attach the grille” will be taken for install-
ing the i-see sensor corner panel.
* The i-see sensor corner panel should be fixed onto the grille
