CHECK THE CHASSIS
Do not apply excessive force when sliding
chassis into cabinet.
6. Slide the chassis into the cabinet until at least 3/4
of the depth of the chassis is supported. The chas-
sis should slide easily on the drain pan rails. DO
NOT APPLY EXCESSIVE FORCE. Ensure that
the chassis will not tip forward before removing
dolly (see
Figure 26 on page 34
).
To avoid damage from clogged coil sur-
faces, plugged motor ventilation open-
ings, and potential unit failure, DO NOT
operate unit without compete enclosure,
supply grille, RA panel, and filter in place.
7. Connect the hoses to the chassis. Ensure that the
hoses cannot be pinched once the chassis is slid
into place.
8.
Without touching the flanges on either side, en
-
sure the chassis' alignment in the cabinet is cen-
tered in the cabinet opening (see
Figure 27 on
page 34
).
9. Complete the electrical connections to the chas-
sis using the two quick-connect mating plugs. The
unit-mounted plug ends are located on the bottom
of the control box.
10. Remove the shipping cover from the face of the
air-to-refrigerant coil.
11. Install the inner service panel and check that the
foam gasket seal between the panel and the chas-
sis is slightly compressed.
If necessary, pull the chassis forward slightly to
ensure an adequate seal between the chassis and
the service panel.
12.
Install the air filter onto the face of the service
panel. Slide the filter upward into the top-re
-
taining clip until the bottom of the filter can be
dropped onto the lower clip.
13. Install service panel.
14. Install the RA panel into the drywall opening if
not already installed. Refer to
Acoustic Return Air
(RA) Panel on page 20
. Secure the panel into
the drywall with six screws.
