Condensate Drain Connections

The main drain line and the trap must be the same size as
the drain connection. Drain traps must be primed. If they
are not, the trap is essentially non-existent and the drain
will likely overflow. Plug or trap the auxiliary drain
connection, if applicable. If the auxiliary drain connection
is left open, air can be drawn in through the opening. This
drawn in air can cause moisture carryover. All drain lines
