3.11 CONDENSATE DRAIN
Consult local codes or ordinances for specific requirements.
IMPORTANT:
When making drain fitting connections to the drain pan, use a thin layer of
Teflon paste, silicone or Teflon tape and install hand tight.
IMPORTANT:
When making drain fitting connections to drain pan, do not overtighten.
Overtightening fittings can split pipe connections on the drain pan.
• Install drain lines so they do not block service access to front of the unit. Minimum
clearance of 24 inches is required for filter, coil or blower removal and service access.
• Although the condensate drain pan is designed is designed to be self draining, it is
recommended that the air-handler cabinet be pitched slightly downward toward the
primary drain connection to assure the condensate drains completely from the drain
pan. The downward pitch should be approximately 1/8” per foot and in both axes.
