Maintenance
Pump Inlet Filter
The AirChek 52 Sampler is fi tted with a fi lter/trap just below the
pump intake. This prevents particles from being drawn into the pump
mechanism. The fi lter should be replaced periodically. Follow this
procedure:
1. Grip the inlet hose barb (Figure 1, #4 on page 9)
and unscrew it counterclockwise.
2. Holding the pump upside down, use a small
fl athead screwdriver or tweezers to remove
fi lter.
3. Place a new fi lter in the intake. Ensure the
rubber gasket inside the inlet hose barb is still
in place.
4. Screw the inlet hose barb back into place.
Replacing the Battery Pack
To enhance battery life, SKC ships battery packs separate from
the pump (see Charging the Battery Pack on page 5). Once installed,
completely charge the battery pack before operating the pump. It
may be necessary to charge the battery a few times before maximum
battery capacity is achieved.
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 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.
Use of a repaired or rebuilt battery pack voids any warranty
and the UL Listing for intrinsic safety.
