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 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 two screws (with captive washer) as well as the two 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, 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.

9.5. Locking the up/down airﬂow direction (Fig. 9-9)

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 6.3.3.

9.6. 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 col- lect.

•Make sure that the wires have been securely connected.

PLA-ABA specifications
