Duct Insulation and Vapor Proofing
Previously installed heating supply ductwork may already
have adequate insulation against excessive heat loss.
This insulation may be satisfactory for protection against
heat gain from summer cooling. Depending upon
application, additional insulation may be required.
Externally insulated ductwork must have adequate vapor
seal for summer operation, especially where duct is
exposed to high humidity conditions.
Condensate Drain
Condensate drain must consist of a minimum of ¾-inch
copper tubing, ¾-inch galvanized pipe, or ¾-inch PVC
pipe. Figure 5 shows condensate drain setup. The drain
trap must be properly configured to ensure the removal of
all condensate runoff. Ensure drain pitches downward at a
slope of one inch every 10 feet.
Note 1: Incorrect trapping can hold water in pan,
causing overflow.
Note 2: Consult local codes for additional precautions
before installing condensate pan.
Caution: If unit location is above an occupied
space or where damage may result from
condensate overflow, install a watertight pan of
corrosion-resistant metal beneath unit to catch
overflow. If this condition exists, a separate
¾-inch condensate drain must be provided for
this added pan. See Figure 6.
