5.Remove indoor blower access panel (Fig. 18).
6.Disconnect
7.Remove screws (Fig. 20) securing evaporator blower hous- ing to blower shelf and carefully slide out blower hous- ing. There is a ®ller bracket attached to the blower shelf; remove this ®ller bracket and retain for later use.
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 ®ller bracket re- moved in Step 7.
10.If unit ductwork is to be attached to vertical opening ¯anges 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.Orient blower housing for vertical air¯ow (blower mo- tor adjacent to horizontal duct opening) and slide into vertical opening making sure the ¯anges 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 ¯ange aligns with the hole in the basepan.
