FOUR-WAY CEILING-CASSETTE INDOOR UNITS
Installation and Best Layout Practices
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-DISPLAY) 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).

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.
