INSTALLATION OF OPTIONAL AIR PANEL: P-AP56NAMS
The operation is continued even if there is no person in a room.
- Object such as a curtain or a leafy plant is swaying in the
wind in the detecting area.
- Moving animal or insect is in the detecting area.
Airflow returns to the motion sensor kit by hitting
-
obstacles such as shelf, locker, etc.
- Direct lights such as sunlight or headlight from outside
enters the detecting area.
- Hot air from a heater, etc. affects directly to the motion
sensor kit.
- Blower device such as ceiling fan or ventilating fan
affects the airflow from the indoor unit.
- Ambient temperature changes drastically.
Excessive force or vibration is applied to the motion
-
sensor kit.
- Fluid or corrosive gas exists on the installing site.
- Continuous use of the indoor unit in a high humidity
environment.
- Weather affects directly to the surface of the motion
sensor.
- Static electricity or electromagnetic wave is generated on
the installing area.
- Moving object with temperature different from
surrounding.
12.4 INSTALLATION

Pay attention to perform the installation work at high-place using a
stepladder, etc.

• Do not move the louvre by hand.
• If moved, the louvre mechanism will be damaged.
• In addition, do not apply an excessive force to the air outlet part to
prevent the breakage.
1 The suspension height of the indoor unit should be referred
to "Installation & Maintenance Manual" of the indoor unit.
2 Do not touch the louvre during the installation work.
3 Remove the air inlet grille from the air panel.

Pay attention that the detecting function is decreased if the lens
for sensor smudges.
In this case, wipe off smudges by a cotton swab soaked
alcohol (Isopropyl alcohol is recommended.) or a soft cloth.
(When wiping off smudges on the lens for sensor, do not apply
excessive force.
If excessive force is applied, the resin lens may be damaged
so that may cause malfunctions such as misdetection or
undetectable of the motion.)

• Perform securely the installation work referring to this installation
manual. If the installation is not completed, it may cause injury by
falling down the motion sensor kit.
• Do not install the motion sensor kit where the flammable gases may
generate or enter.
• Turn OFF the power source completely before performing the
installation work and the electrical wiring work for motion sensor kit.
If not, it may cause an electric shock.
• Do not apply excessive force to remove the corner pocket cover.
Otherwise, it may cause of deformation or damage of the plastic
hook, or may result injury.
• Hold the air panel securely by hands to prevent it from falling when
it is removed.
• Perform securely the electrical wiring work. If the electrical work is
not completed, heat generation at the connection, a fire or an electric
shock may occur.
• Make sure that the electrical wires are securely fixed in order not to
apply an external force to the terminal connections of the wirings. If
fixing is not completed, it may cause heat generation or a fire.
While pushing both ends of knobs at the air inlet grille
toward the arrow direction, open the air inlet grille until the
angle of approximately 45° from the air panel surface. After
lifting the air inlet grille keeping it inclined, draw the air inlet
grille forward.
(Remove the filament tape (4 portions) fixing the air filter.)
