Failure to use recommended sealant could result in
unit performance loss.
If a unit is to be converted to a horizontal discharge, the
following conversion must be performed:
1.
Remove RETURN and SUPPLY duct covers.
2. Locate supply cover. Apply ¼ in. (6mm.) continuous
bead of 500°F RTV sealant to the flange as shown.
3. Position SUPPLY DUCT COVER as shown, rotate 90
degrees to allow entrance into supply opening.
4. Slide SUPPLY DUCT COVER into duct openings until
inward edge of duct cover engages with the 2 retaining
clips on the duct flanges. Secure the outward edge of
each duct cover with 2 screws.
5. Slide RETURN DUCT COVER (insulation side up) into
supply opening until inward edge of duct cover
engages with the 2 retaining clips on the duct flange.

3. Using self-drilling screws, (or screws removed from
duct cover), screw through dimples to attach DUCT
COVER to base.
4. On original RETURN DUCT COVER, apply ¼” (6mm.)
continuous bead of 500°F RTV sealant around flange
(opposite insulation side), as shown.
5. Slide RETURN DUCT COVER (insulation side up) into
