Condenser Fans (6-25 and 30 ton)
Condenser fans and motors can be removed
and reinstalled as individual assemblies.
Removal
Take off the fan grill by removing the
screws that attach it to the orifice.
The condenser fan motor wires can then be
accessed and disconnected.
Remove the screws that attach the orifice to
the condenser assembly. The screws are
located on the top of the orifice around the
perimeter, and in some cases, through the
side of the condenser assembly into the
orifice.
With the wires disconnected and the screws
removed, the fan, motor and orifice
assembly can be lifted off the unit.

with the motor wires on the side closest to
the control panel.
Attach the orifice to the condenser assembly
using all of the points where screws were
removed.
Reconnect the fan motor wires.
Attach the fan grill at all of the points where

Condensate Drain Pans
Drain pans will have moisture present and
require
periodic cleaning to prevent
microbial growth. Cleaning of the drain pans
will also prevent any possible plugging of
the drain lines and overflow of the pan itself.
Cleaning of the drain pans and inside of the
unit should be done only by qualified
service technician.
Electric shock hazard. Shut off all
electrical power to the unit to avoid
shock hazard or injury from rotating
parts.
WARNING
Improper installation, adjustment,
alteration, service, or maintenance
can
cause property damage,
personal injury, or loss of life. Startup
and service must be performed by a
Factory Trained Service Technician.
