Horizontal Discharge Conversion
(3 to 5 Ton Units)
Note: 3 to 5 ton units supply cover to supply opening and
return cover to 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.

TCO1 Instructions for Low NOx Gas
Furnace Option
For units equipped with the low NOx gas furnace option,
the TCO1 is located behind the indoor fan access panel
mounted on the top of the heat exchanger wrapper. See
the below figure for TC01 location.
All the TCO1 tripping values on these units have the same
trippoint for Downflow and Horizontal configurations so
there is no need to make any changes.

3. Position duct cover as shown, rotate 90 degrees to
allow entrance into supply opening.
4. Slide duct covers 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.
