FIELD INSTALLATION OF CONDENSING
UNIT
A mounting plate is provided on top of the case
with pilot holes that provide specific attachment
points for the condensing unit base. The mounting
plate is located above the next to last door on the
right, facing the case.
The condensate pan (if provided) is packed inside
the case and must also be installed and leveled on
top of the case, then hard-wired at the electrical
box.
Exact component location is not critical; however,
the components should be mounted in the
general locations shown to ensure that electrical
connections reach, and the condensate pan has
adequate air flow from the condenser. See location
example below.
