10.5. Locking the up/down airflow direction (Fig. 10-9)
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.
1 Turn 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.
10.6. Installing the wireless sensor (Fig. 10-10)
• 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.
10.7. 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.
10.8. Installing the intake grille (Fig. 10-11)
Note:
E
When reinstalling the corner panels (each with a safety wire attached), connect
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 "11.2. 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.)

recommended.
(It is not necessary to remove the intake grille when maintenance is performed on the elec-
tric component box of the main unit.)
