9.4.2. Temporary installation of the grille (Fig. 9-6)

•Temporarily secure the grille using the bell shaped holes by aligning the corner drain pipe area of the main unit with the two holes of the grille that are marked A and B.

*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)

•Be sure to connect the unit to the connector (white, 10-pole). Next, attach the white glass tube that comes with the main unit so that the tube covers the connector. Close the opening of the glass tube with the fastener.

•Make sure that there is no slack in the lead wire at the clamp of the main unit.

Warning:

If the connector is not covered with the glass tube, tracking resulting in fire may occur.

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.

1Turn off the main power switch.

Injuries and or an electrical shock may occur while the fan of the unit is rotating.

2 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.

9.6. Installing the wireless sensor (Fig. 9-10)

•Pull out the wireless sensor cable from the square hole in the corner panel of the refrigerant piping section of the main unit.

•Feed the cable through the electric component box of the main unit as shown in the illustration, and then connect it to CN90 on the control board. Adjust the length of the cable so the corner panel can be removed, and then secure the cable with the clamp.

9.7. 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.
