12 INSTALLATION OF OPTIONAL AIR PANEL: P-AP56NAMS

12.1 APPLICABLE MODEL

This air panel is applicable to the following indoor unit model:
Air panel
P-AP56NAMS
12.2 TRANSPORTATION AND HANDLING
1 Transport the air panel without unpacking as close to the
installation location.
2 Mount the air panel as soon as possible after unpacking.
3 When the air panel is placed on the floor after unpacking,
place it with the rear side downward (the surface to fit the
indoor unit body) on an insulation material, etc. However,
do not leave the air panel on the floor for long time. It may
cause air leakage due to scratch the seal packing.
12.3 BEFORE INSTALLATION
1 Check to ensure that the following accessories are packed with the air panel.
Name
Long Screw (M5 Cross Screw)
If any of these accessories are not packed in the packing, please contact your contractor.

12.3.1 Motion sensor

Motion sensor detects the human activity by measuring the
level of change in infrared light emitted by humans or objects.
Therefore, the misdetection or undetectable of the motion may
occur under the following situations.
- No alternation of temperature or movement of heat
source in the detection area.
- Obstruction such as glass impervious to infrared light in
the detecting area.
- Heat source moves rapidly in the detecting area.
- Someone is in a room with a little motion.
- Ceiling height is 2.7 meters or more.
- Person is facing their back against the motion sensor or
exposure of the skin is less.

Quantity Purpose
4 For fixing air panel
In addition, if the air panel is placed with the surface
downward, the louvre mechanism may be damaged due to
touch the louvre to the floor, etc.
4 Do not move the louvre by hand. If moved, the louvre
mechanism will be damaged.
- It may be difficult for the motion sensor to detect human
activity on the border of the detection area.
The sensing area for the motion sensor is shown in the figure
