Operation
Once installed using the above instructions, your AF-24xx air cleaner(s) can be operated with the flip of a switch.
Because the AF-24xx
series is designed as an “Air quality Maintenance” 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 door panel of the Main Housing.
To access the motor, pulleys and belt:
Remove the door panel by removing (16) ¼-20x1-1/4
”
bolts with a 3/8 socket.
Troubleshooting Chart
Symptom
Possible Cause(s)
Corrective Action
Excessive belt noise
1. Belt is loose
1. Remove door panel, loosen nuts that fasten motor, turn
adjustment screw until optimum belt tension is achieved
2. Belt needs to be flipped.
2. Follow step (1) to loosen belt, then remove belt and turn it
around. Replace belt, and then reverse step (1) to tighten belt
and re-assemble.
3. Belt is worn out or glazed.
2. Follow step (1) to loosen belt, put new one on, and then
reverse step (1) to tighten belt and re-assemble
Air cleaner has poor
performance.
1. It’s possible that the air cleaner may
have been wired backwards upon
installation. 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.
Air is not staying as clear as
usual
1. Prefilters may be loaded with debris
1. Turn unit off, lock out power to unit, then replace the prefilter
by pushing clips out of the way and then sliding it out and 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 snap around it.
