Finalizing Indoor Unit Installation—
Installing the Decoration Panel
Decoration panel must be installed properly; cool air will leak from any gaps found between the indoor unit frame and the decoration panel,
which will cause condensation to generate.
1. Remove the packaging, take out air inlet grille from the front
panel (1A), and then remove the corner covers of the panel (1B).
2. Attach the panel to the indoor frame by inserting the hooks as
shown (2).
3. Attach two screws on diagonal corners of each panel, but do not
tighten completely (3). Screws to attach the panel to the indoor
unit frame are factory-provided and can be found in the shipping
box.
4. Verify the panel is aligned with the ceiling. Adjust the height by
using the hanging bolts as shown (4).
5. Attach the corner covers (5).
6. Unscrew the control panel cover (6).
7. Connect the one display connector (CN-DISP) and the two vane
control connectors (CN-VANE1, CN-VANE2) of the front panel to the
indoor unit PCB (7).
8. Close the control box cover. Attach the link on the front panel as
shown (8). The link is supplied in the front panel shipping package.
9. Attach the other side of the link on the filter guide of the air inlet grille,
then install the filter and the air inlet grille on the front panel (9).
Figure 218:Ensure that no gaps are present between the
indoor unit frame and the decoration panel.
Insulation should fit tightly so that
cool air does not leak
