3. Package Contents
Verify that all items are present in your Simer M40P Mini-Vac Utility Pump Kit:
- Simer M40P Non-Submersible Utility Pump
- Garden Hose (for discharge)
- Scoop Attachment (for water intake)
4. Setup
- Positioning the Pump: Place the pump on a stable, level surface near the water source. Ensure the pump motor is not submerged in water, as this is a non-submersible unit.
- Connecting the Intake: Attach the scoop attachment to the intake port of the pump (the side without the brass fitting). Ensure a tight connection to prevent air leaks, which can affect priming.
- Connecting the Discharge Hose: Connect the garden hose to the discharge port of the pump (the side with the brass fitting). Route the hose to the desired discharge location, ensuring it is free of kinks and obstructions. The discharge point should ideally be lower than the pump for optimal flow.
- Submerging the Intake: Place the scoop attachment into the water you wish to pump. Ensure the scoop is fully submerged.
- Power Connection: Plug the pump's power cord into a grounded 115V AC/DC electrical outlet.

5. Operating Instructions
- Initiating Pumping: Once the pump is set up and the intake is submerged, plug the power cord into the electrical outlet. The pump will begin to operate immediately as it does not have an on/off switch.
- Monitoring Operation: Observe the water flow from the discharge hose. The pump is designed for efficient and relatively fast water transfer.
- Stopping the Pump: To stop the pump, simply unplug the power cord from the electrical outlet.
- Preventing Dry Running: Always ensure the intake remains submerged in water during operation. If the water level drops below the intake, unplug the pump immediately to prevent damage.
6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your Simer M40P pump.
- Cleaning: After each use, especially if pumping dirty water, flush the pump with clean water to remove any debris. Disconnect hoses and clean the scoop attachment.
- Inspection: Periodically inspect the power cord, hoses, and pump body for any signs of wear, damage, or leaks. Replace damaged components as necessary.
- Storage: Store the pump in a dry, protected area when not in use. Ensure it is drained of all water to prevent freezing damage in cold climates.
- Thermal Protection: If the pump shuts off due to overheating, allow it to cool down completely (approximately 30 minutes) before attempting to restart. Address any potential causes of overheating, such as restricted flow or dry running.
