7. Remove screws securing blower shelf to duct panel. Dis-
card the blower shelf.
8. Locate lances in basepan insulation that are placed over
the perimeter of the vertical discharge opening cover
(Fig. 21).
9. Using a straight edge and sharp knife, cut the insulation
around the perimeter of the cover. Remove the screws
securing the cover to the basepan and slide out the cover
(Fig. 22). Discard the cover. Install filler bracket re-
moved in Step 6.
10. If unit ductwork is to be attached to vertical opening
flanges on the unit basepan (jackstand applications only),
do so at this time.
11. It is recommended that the basepan insulation around
the perimeter of the vertical opening be secured to the
basepan with aluminum tape to prevent the insulation
from tearing or bunching up when the blower housing is
installed in the vertical discharge position.
12. Remove screws securing the high-voltage raceway to duct
panel. See Fig. 24. Temporarily place raceway on top of
unit until blower housing is installed.
13. Orient blower housing for vertical airflow (blower mo-
tor adjacent to horizontal duct opening). See Fig. 25.
Reconnect the plug assemblies. Slide blower housing into
vertical opening making sure the flanges on the blower
side plates engage the tabs in the unit basepan.
Resistance will be felt as the blower housing contacts
the basepan insulation; this can be overcome by apply-
ing a slight force to the base of the blower. Continue
sliding blower in until hole in side plate flange aligns
with the hole in the basepan. Secure using screws re-
moved in Step 6.
14. Reinstall the high-voltage raceway removed in Step 12.
15. Cover the horizontal duct openings. Duct covers can be
ordered as an accessory or be field-fabricated.
16. Reinstall the evaporator coil and evaporator blower ac-
cess panels.
17. After completingunit installation, perform all safety checks
and power up unit.
NOTES:
1. An accessory duct cover is available as an alternative to field
fabrication.
2. Construct duct cover out of 22-gage sheet metal.
3. Dimensions in ( ) are in millimeters.
