Maintenance
Pump Inlet Filter
The 44XR 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 on pages 20-21)
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 on page 22) 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, battery packs should not be
charged 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.
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.
Use of any device other than the approved battery pack to power the
pump voids the UL Listing for intrinsic safety and any warranty.
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.
