the end of the condensate pan and an alternate connection
on the bottom. See Fig. 14. 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
