6. If unit will be started immediately upon completion of
installation, prime trap per procedure outlined in Unit
Start-Up section.
Condensate line must slope downward away from the trap
to drain. If drain level is above condensate trap, condensate
pump must be used. Condensate drain line should be routed
within the conditioned space to avoid freezing of condensate
and blockage of drain line. If this is not possible, a heat
cable kit may be used on the condensate trap and line.
Heating cable kit is available in various lengths; 6 ft. (1.8
m) - kit no. 26K68; 24 ft. (7.3 m) - kit no. 26K69; and 50 ft.
(15.2 m) - kit no. 26K70.
Do Not
use copper tubing or existing copper condensate
lines for drain line.

When combining the furnace and evaporator coil
drains together, the A/C condensate drain outlet must
be vented to relieve pressure in order for the furnace
pressure switch to operate properly.
