9.4.2. Temporary installation of the grille (Fig. 9-6)
• Join the corner of drain pipe on the main unit with the corner with hole on the grille
and put them together temporarily by hanging the hook of the grille to the claw of
the main unit.
9.4.3. Fixing the grille
• By tightening the pre-installed screws, fix the grille onto the main unit. (Fig. 9-6)
Note:
Make sure there is no gap between the main unit and the grille or between the
grille and the ceiling surface. (Fig. 9-7)
If there is a gap between the grille and the ceiling:
With the grille attached, slightly adjust the installation height of the main unit and
clear the gap.
Caution:
• When tightening the screw, make sure that the tightening torque is 2.8 N∙m
to 3.6 N∙m, 2.1 to 2.6 ft∙lbs. Never use an impact screw driver.
• After tightening the screw, confirm that the two grille hooks (Fig. 9-6) are
latched onto the hooks on the main unit.
9.4.4. Wire connection (Fig. 9-8)
• Loose the 2 screws fixing the electrical box cover on the main unit, and slide the
cover to open.
• Route the lead wire from side of the electrical box.
• Make sure to connect a connector for vane motor (white, 20 poles) to CNV con-
nector (white) on the controller board of the main unit.
• Lead wires that lead off the grille must be held together without slack using a clamp
into the electrical box.
9.4.5. Installation of i-see Sensor corner panel (Fig. 9-9)
• Route the lead wire from the side of electrical box.
• Route the lead wire connector (white, 4 poles and white, 5 poles) of the i-see Sensor
corner panel 4 from the side of the electrical box on the main unit and connect to
the connector CN4Z and CN5Y on the controller board.
• The remaining lead wire of i-see Sensor corner panel must be held together without
slack using the clamp into the electrical box.
• Put the cover back on the electrical box with 2 screws.
Note:
Make sure wires are not caught in the electrical box cover.
• The i-see Sensor corner panel should be fixed onto the grille 1 with screw 3.
* If the position of the i-see Sensor was changed from default position (Position 3)
to the other position, change the function settings. (Refer to page 11 and Fig. 9-10)
• The i-see Sensor corner panel can not installed on the drain pipe side for the main
unit. (Refer to Fig. 9-10)
