7. Attaching Panel to Indoor Unit
Install the indoor unit by referring to the installation manual provided
with the indoor unit.
Note
Do not impose force on the swing flap, brush unit, or air filter when
taking out the panel from the packing material (on the bottom side).
7-1 Checks before attaching panel
•Check the directions of the indoor unit and the engraved marks
on the panel as shown below.
The piping block to the PIPING SIDE and the drain socket to the
DRAIN SIDE .
•Stand the temporary latching bracket upright.
•Draw out the lead wires (on the panel side) from the opening.
7-2 Attaching panel
(1) Tentatively put the two temporary latching brackets of the
suction port of the panel (on the internal circumference side) to
the hooks of the indoor unit.
Note
Let go your hands after confirming through the check window
that the temporary latching brackets are engaged with the
hooks.
(2) Remove from the harness opening as described in "6.
Preparations for Indoor Unit" on page5. Pull out the lead
wires disconnected from the decoration cover in the corner
carefully so that lead wries are not caught by the mounting
bracket. See "5. Preparations for Panel" on page4.
(3) Put the mounting brackets (in 4 points) on the corners of the
panel to the hooks of the circumference of the indoor unit.
(Hook the mounting bracket engraved with the PIPING SIDE
first, followed by the mounting bracket on the opposite angle
side.)
At that time, pay attention that the harness and lead wires (on
the panel side) will not be caught between the panel and
indoor unit.
Note
Let go your hands after confirming that the mounting brackets
are engaged with the hooks.
(4) Tighten the four hexagon head screws right under the
mounting bracket for approximately 3/16 in. (5mm.) (The panel
will move upward.)
(5) Turn the panel in the directions of the arrows so that the
opening on the ceiling will be perfectly covered by the panel.
(6) Furthermore, tighten the screw (4) until the distance from the
lower part of the hook of the indoor unit to the lower part of the
panel becomes 4-3/16 (107) to 4-7/16 in. (112mm.)
