Operating Instructions
The wireless remote control allows you to adjust the firmness of each side of your dual chamber mattress independently.
- Power On: The pump unit is typically always on when plugged in. The remote control will activate when a button is pressed.
- Select Chamber: Use the L (Left) or R (Right) buttons on the remote to select the side of the mattress you wish to adjust. The remote display will indicate the selected side and its current firmness setting.

- Adjust Firmness: Use the Up (triangle pointing up) and Down (triangle pointing down) arrow buttons to increase or decrease the firmness level. The numbers on the remote display correspond to the firmness setting, typically ranging from 1 to 100.
- Confirm Setting: Once your desired firmness is reached, the pump will stop automatically. The remote will continue to display the set firmness level.
- Adjust Second Chamber: Repeat steps 2 and 3 for the other side of the mattress if desired.
Maintenance
To ensure optimal performance and longevity of your air pump system, follow these simple maintenance guidelines:
- Cleaning: Wipe the pump unit and remote control with a dry, soft cloth. Avoid using liquid cleaners or abrasive materials.
- Hose Inspection: Periodically inspect the air hoses for any signs of wear, kinks, or damage. Ensure connectors remain secure.
- Ventilation: Ensure the pump unit has adequate airflow around it to prevent overheating. Do not cover the pump with blankets or other materials.
- Storage: If storing the unit for an extended period, disconnect it from power, carefully detach the hoses, and store all components in a dry, cool place.
Troubleshooting
If you encounter issues with your Deelz4Less Sleep Number Air Pump Replacement, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not turn on. | No power supply. | Check if the power cord is securely plugged into both the pump and the electrical outlet. Test the outlet with another device. |
| Remote control display is blank or not responding. | Remote batteries are low or depleted. | Replace the batteries in the wireless remote control. Ensure they are inserted correctly. |
| Mattress is losing air or not inflating properly. | Loose hose connections or air bladder leak. | Ensure all hose connections to the pump and mattress bladders are secure. Inspect hoses for any visible damage or kinks. If the issue persists, the air bladder in the mattress may have a leak (this pump cannot fix bladder leaks). |
| Pump is making unusual noises. | Obstruction or internal issue. | Ensure the pump is on a flat, stable surface and not obstructed. If the noise persists and affects performance, contact customer support. |
If troubleshooting steps do not resolve the issue, please refer to the Warranty and Support section for further assistance.
