5.3. Selection of the air outlets
For this grille the discharge direction is available in 11 patterns. Also, by setting the
Remote controller to the appropriate settings, you can adjust the air-flow and speed.
Select the required settings from the Table according to the location in which you
want to install the unit.
1) Decide on the discharge direction pattern.
2) Be sure to set the remote contoller to the appropriate settings, according to the
number of air outlets and the height of the ceiling on which the unit will be in-
stalled.
Note:
For 3 and 2-directional, please use the air outlet shutter plate (option).
5.4. Installing the grille
5.4.1. Preparations (Fig. 5-5)
• Install the two enclosed screws with washer 2 in the main unit (at the corner drain
pipe area and at the opposite corner) as shown in the diagram.
5.4.2. Temporary installation of the grille (Fig. 5-6)
• 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.
5.4.3. Securing the grille (Fig. 5-7)
• 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.
5.4.4. Wire connection (Fig. 5-8)
• 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.
