5. Operating Instructions
To use your Pursonic OI-200 Water Flosser:
- Select Pressure Setting: Turn the pressure dial on the main unit to your desired setting. Start with a low setting (1-3) and gradually increase as you become accustomed to the water stream. The device offers 10 pressure settings.
- Prepare for Use: Lean over the sink and place the nozzle tip into your mouth. Close your lips slightly to prevent splashing, but allow water to drain into the sink.
- Start Flossing: Press the ON/OFF button on the main unit to start the water flow. Direct the jet stream at a 90-degree angle to your gumline. Move the nozzle along the gumline, pausing briefly between teeth.
- Utilize Timer: The device features a 2-minute auto-timer with 30-second interval alerts. These alerts indicate when to move to a different section of your mouth (e.g., upper right, upper left, lower left, lower right).
- Pause Function: The handle includes a water flow pause button, allowing you to temporarily stop the water stream without turning off the main unit.
- Complete Session: Continue until the 2-minute timer completes or the reservoir is empty. Turn off the device by pressing the ON/OFF button on the main unit.
- Empty Reservoir: After each use, empty any remaining water from the reservoir to prevent bacterial growth.

6. Maintenance
Proper maintenance ensures the longevity and hygiene of your water flosser:
- Daily Cleaning: After each use, empty any remaining water from the reservoir. Rinse the reservoir with clean water.

- Unit Cleaning: Wipe the exterior of the main unit with a soft, damp cloth. Do not use abrasive cleaners or immerse the unit in water.
- Desealing (if necessary): If mineral deposits build up, fill the reservoir with 2 parts water and 1 part white vinegar.

Finish by running a full reservoir of clean water through the unit.
