3.2 Installation method 2: Directly fix the air outlet panel onto the air outlet of the IDU, which is only
applicable for nude packing.
3.2.1 Poke through the corresponding holes of the sponge covering the Mxφ3.2 screw holes on the upper
and lower sides of the following panel;
M X Ø 3.2
3.2.2 Insert the panel into the air outlet of the IDU until it is
propped, and use screws to fix the panel onto the air
outlet of the IDU. Note that the panel needs to be
held while fixing to prevent it from falling.
3.2.3 After installation, check whether the screws are
fixed according to the panel holes. If not, it may
hinder the left and right swing of the louvers.
Make sure to use flat head screws to fix the panel onto the ceiling to prevent the screws
from skewing or loosening, and the screw caps must be completely embedded in the
corresponding concave pits; otherwise, the louver may interfere with the screw cap,
causing the louver not to operate normally. In addition, check whether the louver is
normally reset.
Make sure to add reinforced wooden support for the air outlet at the ceiling opening hole
of the panel. The height of the wooden support is shown in Figure 4.
When fixing the panel, you can press the top louver and move the bottom louver with
moderate strength to release the lock, so as to easily fix the flat head screws with tools;
otherwise, the louvers may permanently be deformed. The lock must be reset after it is
released, otherwise, it may cause abnormality, as shown in Figure 5.
Make sure to add reinforced wooden support for the air outlet; otherwise, unsecured fixing
may result in hidden danger.
If the IDU is too far away from the ceiling or there is a level difference between the IDU
and the ceiling opening, you can make a corresponding soft air duct or insulation air duct
to avoid cold or heat leakage.
4. Open the IDU electric control box cover and connect the panel cable to the IDU electric
control part (refer to Figure 8).

Precautions for wiring: Arrange professional personnel for wiring according to the wiring
diagram. Do not connect the cables with power on. Cable connection with power on or wrong
connection may burn the display box and cause personal injury.

6. Check whether the left and right gaps of the 4 top and bottom louvers are even;

Ensure that there are no gaps between the IDU and the air outlet panel, and between the
Plasterboard
air outlet panel and the ceiling. Otherwise, check whether the screws are fastened tightly
during installation.
If there are still gaps after all screws are tightened, remove the air outlet panel, adjust the
distance from the air outlet of the IDU to the ceiling, and then install the air outlet panel
again.
If the IDU is too far away from the ceiling or there is a level difference between the IDU and
the ceiling opening, you can make and connect the corresponding soft air duct as required.
VI. Confirmation after Installation
Whether there is a gap between the air
outlet panel and the ceiling.
Whether there is a gap between the air
outlet panel and the flange.
Check whether there is a gap between the
flange and the IDU.
Note: The gap (if any) may lead to air
leakage, condensation, abnormal sound and
other problems.
VII. Cleaning of the Air Outlet Panel
1. Wipe the air outlet panel with a dry cloth.
2. If the air outlet panel is extremely dirty, wipe it with a cloth dipped in an aqueous solution of
neutral detergent.
Do not use gasoline, benzene, volatile agents, decontamination powder and liquid
insecticides. Otherwise, the air outlet or panel may de-color or deform.
Do not expose the inside of the IDU to moisture, as it may result in electric shock or fire.
When cleaning the air guide louver with water, do not scrub it violently.
