Step 9 — Install External Condensate Trap and
Line
The unit has one
3
/
4
-in. condensate drain connection on the end
of the condensate pan and an alternate connection on the bot-
tom. See Fig. 32. Unit airflow configuration does not deter-
mine which drain connection to use. Either drain connection
can be used with vertical or horizontal applications.
When using the 50TC*16 standard side drain connection, en-
sure the red plug in the alternate bottom connection is tight. Do
this before setting the unit in place. The red drain pan can be
tightened with a
1
/
2
in. square socket drive extension.
To use the alternate bottom drain connection, remove the red
drain plug from the bottom connection (use a
1
/
2
-in. square
socket drive extension) and install it in the side drain
connection.

The piping for the condensate drain and external trap can be
completed after the unit is in place. See Fig. 33.
Fig. 33 — Condensate Drain Piping Details
All units must have an external trap for condensate drainage.
Install a trap at least 4-in. (102 mm) deep and protect against
freeze-up. If drain line is installed downstream from the exter-
nal trap, pitch the line away from the unit at 1-in. per 10 ft
(25 mm in 3 m) of run. Do not use a pipe size smaller than the
unit connection (
3
/
4
-in.).
See Fig. 34-45 for wiring diagrams.
