5.4.4. Wire connection (Fig. 5-8)
• 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 controller board of the unit.
The lead wire of grille is passed through the catch for 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.
5.5. Installing the intake grille (Fig. 5-9)
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 "5.2. 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.
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.)
i-see sensor (PLP-6BAE panel)
5.6. Installation of i-see sensor corner panel
(Fig. 5-10)
For PLP-6BAE panel
• Take the lead wires CN4Y (white) and CN6Y (red) of the i-see sensor corner
panel 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
grille with the fastener 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 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 "5.2. 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
5.7. Locking the up/down airflow direction (Fig. 5-11)
The vanes of the unit can be set and locked in up or down orientations depending
upon the environment of use.
• Set according to the preference of the customer.
The operation of the fixed up/down vanes and all automatic controls cannot
be performed using the remote controller. In addition, the actual position of the
vanes may differ from the position indicated on the remote controller.
Turn off the main power switch.
Injuries or an electrical shock may occur while the fan of the unit is rotating.
Disconnect the connector for the vane motor of the vent that you want to lock.
(While pressing the button, remove the connector in the direction indicated by
the arrow as shown in the diagram.) After removing the connector, insulate it
with tape.
It also can be set by remote controller. Refer to 4.7.
5.8. Check
• Make sure that there is no gap between the unit and the grille, or between the
grille and the surface of the ceiling. If there is any gap between the unit and the
grille, or between the grille and the surface of the ceiling, it may cause dew to
collect.
• Make sure that the wires have been securely connected.
• For PLP-6BAE, check the rotating movement of the i-see sensor. If the i-see
sensor does not rotate, review the procedure in "5.6. Installation of i-see sensor
corner panel".
should be fixed at the rib of the
