Indoor Condensate Drain Piping
Observe all local sanitary codes when installing condensate drains.
WARNING
See Table below for Condensate Drainage port size.
Pitch the condensate drain pipe at a gradual 2.5% pitch (Example: ΒΌ-in drop over a 10-in length)
without obstructions. Use pipe hanger/brackets to support the condensate drain pipe from dropping.
NOTE: Insulate entire interior section of condensate hose and/or pipes to prevent sweating
which may cause water stains or wall damage.
