Installing the panel
1. Align the "PIPING SIDE" and "DRAIN SIDE" sections marked on
the panel with the corresponding piping connector and water
discharge connector of the unit.
2. When installing the panel, first hang its hooks on the swing motor
side and opposite side of the panel to the corresponding drainage
pan hooks on the unit (see a in the figure). Then, hang the two
remaining panel hooks to the corresponding suspension bracket of
the unit (see b in the figure).
3. Slot the guide wire of the swing motor to the card slot on the panel,
and connect the power supply terminal of the swing motor to the
corresponding connector of the electric control box.
1. Secure the installation cover rope onto the bolt on the installation
cover with screws.
2. Gently press the installation cover into the panel.
4. Adjust the four panel hook screws to keep the panel level, and lift
it evenly up to the ceiling (see a in the figure).
5. Adjust the panel slightly in the direction indicated by d in the figure,
so that the center of the panel aligns with the center of the opening
of the ceiling. Verify that the hooks in all four corners are securely
in place.
6. Continue to evenly tighten the screws under the hooks of the panel
until the foam thickness between the unit and the air outlet on the
panel is reduced to about 4–6 mm, and the panel has a steady
contact with the ceiling surface.

The plastic cover plate protruding from the swing motor must
be embedded within the concave area of the sealing plate.
Make sure the wiring of the swing motor is not caught inside
the sealed foam.
Improper screw tightening will result in the fault shown in the
right figure.
If there is still a gap between the ceiling and panel after the
screws are tightened, re-adjust the IDU height (Figure I).
Without affecting the lifting, lowering, and levelness of the IDU
and the water discharge piping, you can use the openings at
the four corners of the panel to adjust the IDU height (Figure
II).
First hang the air inlet grille on the panel, and then connect the
leads of the swing motor and control box to the corresponding
connectors on the unit respectively.
Reinstall the air inlet grille by performing the steps used to
remove the air inlet grille in the reverse order.
Reinstall the installation cover.
