Step 1: Mount Panel to Indoor Unit
1. Carefully grab the air intake grille with your
fingers and slowly pull it out and allow it to hang
from the panel as shown in Fig. 7.1 below. This is
necessary to access some of the holes for the
mounting screws to attach the panel to the unit.
2. Now, with the assistance of another person,
carefully raise and position the cassette face
panel into place. There are tabs, as shown in Fig.
7.2 below, that will align the cassette panel to the
indoor unit. Make sure these tabs are aligned and
the cassette is properly seated to the indoor unit
before attempting to install the mounting screws.
3. Now, manually rotate the air deflector (louver) of
the panel. This will allow access to a mounting
hole that is protected by a cover. Please see Fig.
7.3. NOTE: this cover must be opened before
one of the M4*22 screws in the next step can
be installed.
Grab at these locations
4. Then, secure the panel by installing three M4*22
screws and one ST3.9*16 in locations shown in
Fig. 7.3 below and close the screw cover behind
the air deflector (louver).
5. Now, open the two covers on each side of the
panel and install three m4*22 screws in the
locations shown in Fig. 7.4 below. NOTE: there
are eight M4*22 screws provided, only six
will be used for the installation. There are
two ST3.9*16 screws provided, only one will
be used for the panel installation. The
remaining screws are to be kept as spares.
