Setup
- Unpacking: Carefully remove the pump from its packaging. Inspect for any signs of damage during transit.
- Discharge Hose Connection:
- Attach a 1.25-inch discharge hose to the top discharge port of the pump. Secure it with a hose clamp (not included) to prevent leaks.
- Alternatively, use the provided 3/4-inch garden hose adapter for connecting a standard garden hose.
- Ensure the discharge hose is routed away from the area to be dewatered and leads to a suitable drainage point.
- Placement: Position the pump in the lowest point of the area to be dewatered. Ensure the pump is stable and upright. The pump must be fully submerged in water during operation.
- Power Connection: Connect the pump's power cord to a grounded 115 Volt electrical outlet. Ensure the outlet is protected by a Ground Fault Circuit Interrupter (GFCI) for safety.
Operating Instructions
The BJM Pumps R100-115 does not include an integrated float switch, meaning its operation is manual or requires an external control device.
- Initiating Operation: Once the pump is properly set up and submerged, plug the power cord into the GFCI-protected 115V outlet to start the pump.
- Monitoring: Observe the pump's operation to ensure water is being discharged effectively. The pump should run smoothly without excessive noise or vibration.
- Stopping Operation: Unplug the pump from the electrical outlet to stop its operation. Do not allow the pump to run dry for extended periods, as this can cause damage.
- Continuous Operation: For continuous dewatering, ensure the pump remains submerged. If the water level drops below the pump's intake, unplug it immediately.
Maintenance
Regular maintenance ensures the longevity and efficient performance of your pump.
- After Each Use:
- Disconnect power.
- Rinse the pump thoroughly with clean water to remove any debris, especially if used in salt water or dirty conditions.
- Inspect the intake screen for blockages and clean as necessary.
- Periodic Inspection:
- Check the power cord and plug for any cuts, abrasions, or damage.
- Ensure all connections are secure.
- Inspect the pump housing for cracks or damage.
- Storage: When not in use, store the pump in a clean, dry, and frost-free location.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not start. | No power; tripped GFCI; clogged impeller. | Check power connection and outlet; reset GFCI; disconnect power and clear impeller. |
| Pump runs but no water is discharged or flow is low. | Clogged intake screen or discharge hose; air lock; pump not fully submerged. | Disconnect power and clear blockages; ensure pump is fully submerged; prime pump if necessary. |
| Pump makes excessive noise. | Debris in impeller; pump running dry; worn bearings. | Disconnect power and clear debris; ensure pump is submerged; contact service if noise persists. |
If troubleshooting steps do not resolve the issue, contact qualified service personnel.
