Maintenance
Clean the Pump Inlet Filter
The 44XR Universal Sample Pump is fitted with a filter/trap inside a clear plastic intake port housing. This prevents particles from being
drawn into the pump mechanism. Visually check the filter to ensure that it does not become clogged. If maintenance is necessary, follow
this procedure:
1. Clean dust and debris from around the filter housing.
2. Remove the four screws and the front filter housing.
3. Remove the O-ring.
4. Remove and discard the filter membrane.
5. Clean the filter housing.
6. Insert a new filter membrane and the O-ring.*
See Replacement Parts.
7. Reattach the front filter housing and cross-tighten the four screws.
* Replace with new O-ring only as needed.
Maintain the Battery Pack
For proper maintenance of battery packs, SKC offers chargers
(see Accessories)
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/
To comply with intrinsic safety regulations, battery packs should not be charged in hazardous locations.
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.
Replace the Battery Pack
See Install the Battery Pack.
Notes and Cautions
• Use of a repaired or rebuilt battery pack voids any warranty and the UL Listing for intrinsic safety.
• Use only SKC-approved charger and battery pack designed for the Universal Sample Pump to ensure reliable performance. Failure to do so voids
any warranty and 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.
