1. The mounting hole "footprint" of
the replacement compressor
assembly mounting bracket most
likely does not match the
mounting hole footprint of the
original bracket. Either way, the
original mounting bracket hole
configuration must be re-used
when installing the new
compressor. On units using the
2-hole mounting bracket, that
original mounting bracket must
be used again. In this case, cut
the tie wrap securing the new
compressor to its mounting
bracket, remove the two screws
securing the existing compressor
to its mounting bracket, then
attach the new compressor to the
original mounting bracket using

the two screws and the slotted
mounting holes used on the original
mounting bracket.
Reconnect the air hose which was
removed in step 7 of this section to the
compressor fitting.
With the new compressor installed on
the mounting bracket with the matching
mounting hole footprint, install the
mounting bracket with the new
compressor where the original assembly
had been. Secure the compressor
mounting bracket using the nuts and
lock washers removed in step 6 of this
section. If using the original 2-hole
mounting bracket, torque the two nuts
to 10 in/lb. If using the mounting
bracket that came with the new
compressor, torque the four nuts to 4 in/
lb.
Connect the new compressor green
power connector to the same place
from which the original compressor
power connector was removed in step 5
of this section, then tighten the two end
screws to secure it in place.
Reinstall the front cover removed in step
4 of this section. If it was placed upside
down on the lid of the unit during this
procedure, carefully turn the cover back
over and work it back into position, past
the wires and other components in the
enclosure. Reinstall the four corner
screws securing the front cover to the
chassis.
Reconnect the ground wire by inserting
it behind the retaining screw from which
it was removed, then tighten the
retaining screw. Reconnect the green
power connector by holding it in place
then tightening the two captive screws
removed in step 3 of this section.
Reconnect both ends of the orange
ethernet cable removed in step 3 of this
section. It does not matter which end of
the ethernet cable goes into which
receptacle.
