limit switch change out for horizontal airflow
applications. Refer to the following instructions to
determine if this process is required for the unit
undergoing installation.

horizontal discharge, proceed toTCO-1 instructions.
Horizontal Discharge Conversion WSC060-
120E (5 - 10 Ton Units)
Note: 5 - 10 ton units supply cover to return opening and
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 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.
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
