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
bottom. See Fig. 18. Unit airflow configuration does not de-
termine which drain connection to use. Either drain connec-
tion can be used with vertical or horizontal applications.
Fig. 18 — Condensate Drain Pan (Side View)
When using the standard side drain connection, ensure 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. 19.
All units must have an external trap for condensate drain-
age. Install a trap at least 4-in. (102 mm) deep and protect
against freeze-up. If drain line is installed downstream from
the external 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.).
