NOTE: Vinyl tubing may be used for condensate drain.
Tubing must be 1-1/4" ODX1"ID and should be attached
to the drain on the trap using a hose clamp.
5. Figure 45 shows the furnace and evaporator coil using
a separate drain. If necessary, the condensate line from
the furnace and evaporator coil can drain together. See
Figure 46. The field provided vent must be a minimum
1" to a maximum 2" length above the condensated drain
outlet connection.

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.
Evaporator Coil Using a Separate Drain
Do Not use copper tubing or existing copper condensate
