Air cleaner has poor perfor-
mance.
1. It
’
s possible that the air cleaner may
have been wired backwards upon instal-
lation. Air will blow out the exhaust
either way, but if wired correctly it
should blow at about 58 mph.
1. If the motor is wired to run the wrong direction, disconnect
power supply, & switch the necessary wires around to reverse
the motors rotation with the voltage you are using.
2. The bag filter may not be seated
properly
2. Reach in each pocket to make sure fabric is not between
filter stop and filter frame.

usual
1. Prefilters may be loaded with debris

sliding a new one in.
2. Bag filter(s) may be spent
2. Follow step (1) to remove the prefilter, then if unit is
equipped with clips, push them out and away from the bag
filter, slide out the old bag filter and slide in new one until clips

Operation
Once installed using the above instructions, your AF
-
31243 air cleaner(s) can be operated with the flip of a
switch. Because the AF

”
system, it is important that
the units are turned on in the beginning of the shift and left on until the end of the shift. The reason the
units need to remain on is because Air Cleaners train the air current throughout the entire area in order to
ensure that all of the air is cycling through the filters. The process of training the air can take a while, but is
usually about 30 minutes.
Maintenance
Follow these precautions when performing maintenance on the motor or blower.
Turn off motor, and LOCK OUT electrical service to the unit.
LOCK OUT even when changing filters.
Change filters regularly to maintain optimum performance. If the performance of your air cleaners appears
to be declining, try replacing the filters.
Be sure that replacement filters are always rated for the correct CFM and air flow.
NOTE FOR INSTALLING BAG FILTERS:
When installing fiberglass bag filters, MAKE SURE THAT NO FABRIC IS PINCHED BETWEEN THE HEADER
AND FILTER FRAME.
Performance will decrease dramatically if bag filters are not properly installed. To
ensure no fabric is pinched, place your fingers inside each cell, and gently move each bag cell side to side,
freeing any fabric sandwiched between the header and filter frame.
If the system requires maintenance exceeding filter change, read below

Take the unit down and place it on a level surface that allows access to the access panels on each side of the
