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.

Suction Filter (55, 65 and 75-140 ton)
In an effort to help protect the compressors
from contaminants during testing and startup,
AAON is now factory installing pleated
replaceable core suction line filters on the
RNE Series products (55, 65, and 75-140
tons)
Figure 47 - RPE-48-BD filter element
One month after startup, remove the RPE-48-
BD filter element for the lowest possible
pressure drop. Removing the suction line
filter will improve the efficiency and capacity
of the unit. AAON installs isolation ball
valves on both sides of the suction line filter
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.
