Horizontal Discharge
Conversion (A.0 Cabinet Units)
Note: On A.0 cabinets, use supply duct cover on supply
opening and return duct cover on return opening.
Supplies needed by installer for conversion: 3 oz. tube of
high temperature RTV sealant. (500°F / 260°C: similar to
Dow Corning 736).
Important: 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.
Figure 54. Supply duct cover
3. Position duct cover as shown, rotate 90 degrees to
allow entrance into supply opening.
4. Slide duct covers into duct openings (insulation side
up) 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. After completing installation of the duct covers for
horizontal discharge, proceed to TCO1 instructions.
Horizontal Discharge
Conversion (B.0 and C.0 Cabinet
Units)
Note: B.0 and C.0 cabinet units move the supply cover to
return opening and return cover to supply opening.
Supplies needed by installer for conversion: 3 ounce tube
of high temperature RTV sealant (500°F / 260°C, similar to
Dow Corning 736).
Note: 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. Place SUPPLY DUCT COVER over downflow return
opening (insulation side down).
3. Using self-drilling screws, (or screws removed from
duct cover), screw through dimples to attach DUCT
COVER to base.
