Maintenance
Pump Inlet Filter
The PCXR4 Sampler is fi tted with a fi lter/trap inside a clear plastic intake port
housing. This prevents particles from being drawn into the pump mechanism.
The fi lter should be visually checked to assure that it does not become clogged.
If maintenance is necessary, follow this procedure:
1. Clean dust and debris from around the fi lter housing.
2. Remove the four screws and the front fi lter
housing.
3. Remove and discard the fi lter membrane.
4. Remove O-ring.
5. Clean the fi lter housing.
6. Insert O-ring
*
and a new fi lter membrane. See
Replacement Parts, pages 22-23.
7. Reattach the front fi lter housing and
cross-tighten the four screws.
* Replace with new O-ring only as needed.
Battery Pack Care
For proper maintenance of battery packs, SKC offers chargers (see Optional
Accessories, page 24) that condition the battery for optimum performance
in 6 to 8.5 hours. For optimum charge, ensure pump is not running during
charging. Follow charger instructions.
Fully charge packs before use. For more information on SKC pump batteries,
visit http://www.skcinc.com/instructions/1756.pdf.
To comply with intrinsic safety regulations, do not charge or operate the pump
from the charger in hazardous locations.
Using a non-approved charger voids any warranty.
Use of a repaired or rebuilt battery pack voids any warranty and the UL Listing
for intrinsic safety.
Use of any device other than the approved battery pack to power the pump voids
the UL Listing for intrinsic safety and any warranty.
Ensure proper orientation of charging cable before plugging it into the charging
jack. Improper orientation/contact will short-circuit the battery and voids any
warranty.
Short-circuiting the battery pack will render it immediately inoperative.
Failure to follow warnings and cautions voids any warranty.
The battery pack may be kept on the SKC-approved charger for an indefi nite time.
