5. Setup Instructions

1. Unpack and Inspect: Carefully remove the pump from its packaging. Inspect the pump, power cable, and any accessories for signs of damage. Do not use if any damage is observed.
2. Hose Connection: Attach a 2-inch discharge hose to the pump's outlet. Ensure the connection is secure to prevent leaks during operation.
3. Placement: Position the pump on a stable, level surface in the area to be dewatered. Ensure the pump is fully submerged in the liquid before starting. The pump is designed to handle solids up to 1 inch in diameter, so ensure the intake is clear of larger obstructions.
4. Power Connection: Connect the molded 25’ power cable to a grounded 115V electrical outlet protected by a GFCI. Ensure the power cable is not kinked or under strain.

6. Operating Instructions

1. Submerge Pump: Ensure the pump is completely submerged in the water to be pumped. Operating the pump dry can cause severe damage.
2. Start Pump: Plug the pump into the GFCI-protected 115V outlet. The pump will begin operating immediately.
3. Monitor Operation: Observe the pump's operation. Ensure water is being discharged effectively and that the pump is not struggling or making unusual noises. The pump is designed for continuous duty when fully submerged.
4. Debris Handling: The pump's abrasion-resistant cast iron impeller with neoprene rubber overlay is designed to handle trash and solids up to 1 inch. If the pump clogs, disconnect power immediately before attempting to clear the obstruction.
5. Stop Pump: To stop the pump, simply unplug it from the electrical outlet.

7. Maintenance

Regular maintenance ensures optimal performance and extends the life of your Multiquip ST2040T pump. Always disconnect the pump from the power source before performing any maintenance.

• Impeller Clean-out: The pump features an easy impeller clean-out design. Periodically inspect the impeller for debris accumulation and clear as necessary to maintain efficient pumping.
• Housing and Intake: Clean the pump's cast iron housing and intake screen regularly to prevent blockages and ensure proper water flow.
• Power Cable: Inspect the 25’ power cable and strain relief for any cuts, abrasions, or damage. Replace if damaged.
• Seals and Bearings: The pump is equipped with dual shaft seals and sealed ball bearings. These components are designed for long life and typically do not require user maintenance. If leaks or unusual noises occur, professional service may be required.
• Storage: When not in use, clean the pump thoroughly, drain any remaining water, and store it in a dry, protected area away from extreme temperatures.
