Maintenance
Replace the Pump Inlet Filter
The AirChek 52 Sampler is fitted with a filter/trap just below the pump inlet. This prevents particles from
being drawn into the pump mechanism. The filter should be replaced periodically as follows:
1. Grip the inlet fitting
(see right)
and turn it counterclockwise to unthread it.
2. Holding the pump upside down, use a small flat-head screwdriver or tweezers to remove the filter.
3. Place a new filter in the inlet. Ensure that the rubber gasket inside the inlet fitting is still in place.
4. Thread the inlet fitting back into place.
Replace the Battery Pack
Use of a repaired or rebuilt battery pack voids any warranty and the UL Listing for intrinsic safety.
1. Loosen two security screws on bottom of pump case and allow them to fall to the out position.
2.
Pinch battery pack release arms and pull the bottom half of the pump case away from
the top half.
3. Align arms on top half of case with slots on either side of the new battery pack
housing. Ensure that the back of the battery pack with the charging jack is on the
same side as the belt clip.
4. Slide battery pack up until arms click into place.
5. Push each security screw into the battery pack housing and tighten.
Once installed, completely charge the new battery pack before operating the pump
(see Charge the Battery Pack)
. It may be necessary to
charge it a few times before achieving maximum battery capacity.
