Airflow Systems Dust Collector DCH2-PG6

The adsorption material (activated carbon or other) can be emptied from the module and refilled with fresh adsorber. Use the large opening to fill the majority of the module

After as much material can be put in as possible, use the small filler hole on top of the large cover plate. It is important to get the AD module as full as possible as any low spots or air gaps will allow the air being filtered to by-pass or be exposed to a reduced amount of scrubbing

Always dispose of the spent adsorption material in accordance with local, state and federal regulations. Follow the instructions below to fill the AD Module. When filtering flammable materials, it may be necessary to have the unit meet Class I, Group D electrical requirements

1. Remove module and take to a well ventilated area: DUST IS RELEASED DURING THE REFILLING OPERATION

2. Remove the poly pre-filter and after filter pads and discard properly. (The screen securing the inner afterfilter and the rod securing the outside pre-filter pad are to be set aside for re-use.)

3. Remove large cover plate and empty module contents into a plastic bag or other approved container. WEAR ADEQUATE PERSONAL PROTECTIVE DEVICES

4. Refill with the new adsorber material. After refilling, shake module to pack granules tightly before replacing cover plate to make sure module is full. Remove the small cover plate and top off any void in the module

5. Install new afterfilter poly pad, (2AZ10013, the shorter length), by pressing into place on interior of module cylinder and securing in place using the screen removed in step #2

Check the motor/blower compartments for any packing materials and remove

Warning: This maintenance check requires trained personnel with PPE!

Blower wheels in good condition

Friction joints of arms in good condition

No dirt build-up on blower wheel and other rotating parts

Caster wheel bearings moving freely

Parts that need repair or replacement

Confirm unit has completed any cleaning cycle

Follow lock-out/tag-out procedures preventing unit operation

Loosen knob in center of filter cover. Remove filter cover (Note: knob stays with cover)

There are two filters located behind the filter cover. If required, a plastic bag can be used to slide over each filter as they are removed from the filter housing. CAUTION: Dirty filters can be extremely heavy and awkward to handle. WEAR PERSONAL PROTECTIVE EQUIP- MENT AS REQUIRED

While the filter is out, inspect the Vibra-Pulse® hoses for cracks, splits or degrading. Conical end wear is normal. All hoses should be approximately 7\ long. Replace any hose that does not appear normal or which is worn to less than 6\""

Install new filters. *Small diameter gasket to be installed first (large diameter toward cap)

Inspect perimeter gasket on cabinet opening for damage and replace as necessary. Remove any debris accumulations

Locate and install filter cover assembly. Hand tighten securely, but do not over-tighten

Sign off on the filter replacement

Ensure the Dust-Pak® dust collector is placed in the desired work area and no equipment will come into contact with the unit.

Is the hood approximately 10\ - 14\" from the source of smoke or dust?"

Switch the unit ON, allowing the contaminated air to be drawn into the collection unit.

Has the airflow volume decreased due to dirty filters?

Turn off the Dust-Pak® dust collector to initiate the Auto Clean Vibra-Pulse® filter cleaning system.

Adjust the control board if required to optimize cleaning.

Is the cleaning system initiated by loss of fan pressure?

Does the 'power on' LED light come on when the timer/power board is energized?

Do the individual output lights come on one at a time, in sequence?
