Field Upgrade Guide
7. Move the installation template to the other side
of the air cleaner enclosure. Place the template
onto the enclosure as indicated in Figure 13. The
template must be pushed towards the back of the
air cleaner enclosure until the front flange of the
installation template is fully seated against the
leading edge on the case. The template must also
be pushed towards the one inch U channel filter
rail as shown in Figure 13.
8. Drill two holes, using the template to guide the
drill bit as done previously.
NOTE: The filter mount rails are not installed in
the same orientation. If they are installed the
same way, the screw heads will be in the way of
the filter installation.
9. Secure the second rail into place using the
provided screws. The metal tabs should be facing
the front of the air cleaner enclosure. One of the
tabs should be flush with the front of the enclosure
and the other will extend past the front of the
enclosure.
10. With the rail now firmly affixed to the air
cleaner enclosure with two screws, it may be
desirable to add an optional third screw on this rail
for extra support. A third hole is provided for this
purpose, as well as a screw. Use the existing hole
located in the center of the rail as a guide much
like the installation template was used earlier to
prevent the drill bit from walking.
11. Install the FIELD CHARGER and lock into place by
bending one locking tab on the cabinet. See Fig. 16.
12. Install the PRE-FILTER and COLLECTION CELLS.
13. Each COLLECTION CELL must be oriented with the
handles toward the front.
14. The door can be installed in either direction. Deter-
mine which direction will best allow access to the latches
and 24 volt power cord. Insert the 2 tabs on the door
behind the front cabinet flange and rotate the door into the
closed position. Rotate the two quarter-turn latches on the
Power Door inward.
NOTE: The door has a safety switch to ensure power is
interrupted when the door is removed. This switch is open
when the door is removed from the cabinet. When the door
is properly installed, an actuator tab located in the cabinet
will close the switch, allowing power to the electronics.
