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. 13. Unit airflow configuration
does not determine which drain connection to use. Either
drain connection can be used with vertical or horizontal
applications.
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.
