3. Use the '+' and '-' buttons to set your desired target pressure (e.g., 15 PSI for a SUP). The real-time pressure will be displayed.
4. Press the start button to begin inflation. The pump will automatically switch from high-volume low-pressure stage to low-volume high-pressure stage.
5. The pump will automatically stop once the set pressure is reached.
6. Disconnect the hose from the inflatable item and the pump.

Cleaning and Storage

• Wipe the pump exterior with a soft, dry cloth. Do not use harsh chemicals or abrasive cleaners.
• Ensure the pump is completely dry before storing.
• Store the pump and its accessories in a protective bag or case in a cool, dry place, away from direct sunlight and extreme temperatures.

6. Troubleshooting

If you encounter issues with your dwndpump D16PRO, refer to the following common problems and solutions:

• Pump not turning on: Ensure the battery is charged. Connect to a power source and check if the charging indicator lights up.
• Pump not inflating:
  • Check hose and adapter connections for leaks. Ensure they are securely attached.
  • Verify that the correct valve adapter is used for your inflatable.
  • Ensure the target pressure is set above the current pressure.
• Pump overheating: The pump has an active cooling system. If it still feels excessively hot, allow it to cool down before resuming operation. Continuous operation in very hot environments may trigger thermal protection.
• Pump stops prematurely: This is likely due to the intelligent pressure safety system, which automatically stops inflation once the set target pressure is reached. Check the set pressure on the LED display.
• Inaccurate pressure reading: Ensure the hose and adapter are fully sealed. A loose connection can affect readings.

If problems persist, please contact customer support.
