• Intake Screen: Protects the impeller from large debris.
• Outlet Nozzle: Where water exits the pump.

4.2 LCD Controller

The controller allows for precise adjustment of pump settings.

• LCD Display: Shows current flow rate, speed setting, and error codes.
• Up/Down Buttons: Adjust pump speed.
• Mode Button: Selects different operating modes (if applicable).
• Feed Button: Initiates a temporary pause for feeding.

5. Setup and Installation

Follow these steps for proper installation of your EP3500 pump:

1. Unpack: Carefully remove all components from the packaging. Inspect for any damage.
2. Choose Placement: The EP3500 can be used submersibly or externally. For submersible use, place the pump in the desired location within your sump or reservoir, ensuring it is fully submerged. For external use, ensure the pump is placed below the water level of the intake to allow for gravity priming.
3. Connect Tubing: Attach appropriate hose connectors to the pump's inlet and outlet. Securely connect your aquarium or pond tubing to these connectors. Ensure all connections are tight to prevent leaks.
4. Connect Controller: Connect the pump cable to the LCD controller. Then, connect the power adapter to the controller.
5. Power On: Once all connections are secure and the pump is either submerged or primed (for external use), plug the power adapter into a suitable electrical outlet.

6. Operating Instructions

The LCD controller provides intuitive control over the pump's functions.

1. Power On/Off: The pump will start automatically when connected to power. To turn off, disconnect from the power outlet.
2. Adjusting Flow Rate: Use the 'Up' and 'Down' arrow buttons on the controller to increase or decrease the pump's speed and thus the flow rate. The LCD display will show the current speed setting.
3. Feed Mode: Press the 'Feed' button to temporarily pause the pump for a set duration (e.g., 10 minutes) to allow for feeding without water circulation. The pump will automatically resume operation after the timer expires. Press 'Feed' again to cancel the mode early.
4. Mode Selection: If your controller has a 'Mode' button, press it to cycle through any available special operating modes (e.g., wave-making, constant flow). Refer to the display for the active mode.

7. Maintenance

Regular maintenance ensures optimal performance and longevity of your pump.

1. Disconnect Power: Always unplug the pump from the power outlet before any maintenance.
2. Clean Impeller: Periodically remove the pump's front cover and impeller assembly. Clean the impeller and its chamber thoroughly to remove any debris, algae, or mineral buildup. A small brush can be helpful.
3. Clean Intake Screen: Ensure the intake screen is free from blockages to maintain proper water flow.
4. Inspect Power Cord: Check the power cord and connections for any signs of wear, cuts, or damage.
5. Reassemble: After cleaning, carefully reassemble the pump, ensuring all parts are correctly seated and sealed.

8. Troubleshooting

If you encounter issues with your pump, refer to the following common problems and solutions:

• Pump Not Starting:
  • Check if the power adapter is securely plugged into the outlet and the controller.
  • Ensure the controller cable is firmly connected to the pump.
  • Verify there is power to the outlet.
  • Inspect the impeller for any obstructions preventing it from spinning.
• Reduced Flow Rate:
  • Clean the impeller and pump chamber for debris or buildup.
  • Check the intake screen for blockages.
  • Ensure tubing is not kinked or obstructed.
  • Verify the pump speed setting on the controller is at the desired level.
• Unusual Noise:
  • Disconnect power and inspect the impeller for foreign objects or damage.
  • Ensure the pump is properly seated and not vibrating against hard surfaces.
  • Check for air trapped in the pump or tubing (especially for external setups).
• Error Codes (e.g., Er-03):
  • If an error code appears on the LCD, disconnect power, wait a few minutes, and then reconnect.
  • Common error codes often indicate impeller blockage or dry running. Clean the impeller and ensure the pump is submerged/primed.
  • If the error persists, contact customer support.
