WARNING
Hazardous Voltage!
Disconnect all electric power, including remote
disconnects before servicing. Follow proper lockout/
tagout procedures to ensure the power can not be
inadvertently energized. Failure to disconnect power
before servicing could result in death or serious injury.
1. Remove the heat section access panel.
2. RemoveTCO1 from shipping location, attached to the
combustion blower.
3. Replace and discard the existingTCO1 originally
installed at the factory for down flow operation with
theTCO1 shipped attached to the combustion blower
for horizontal operation.
4. Replace heat section access panel.

Horizontal Discharge Conversion

(6 to 10 Ton Units)
Note: 6 to 10 ton units the supply cover to return opening
& return cover to supply opening.
Supplies Needed by Installer for Conversion: 3 oz. tube of
highTemperature 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. Place SUPPLY DUCT COVER over down-flow 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.

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
supply opening until inward edge of duct cover
engages with the 2 retaining clips on the duct flange.
Secure outward edge of the duct cover with two
screws.
Note: If unit is equipped with Return Air Smoke Detector,
refer to field conversion instructions for horizontal
discharge before installing return air duct.
Note: If unit is equipped with Discharge Air Sensing
option refer to the following figure for proper tube
positioning based on unit tonnage.
