Attaching Nozzles

Operating Instructions
Selecting a Mode
The Mornwell Water Flosser offers three cleaning modes to suit various oral care needs. Press the 'Mode' button to cycle through them:
- Normal Mode: Designed for experienced users, providing powerful cleaning.
- Soft Mode: Recommended for first-time users and individuals with sensitive teeth or gums.
- Pulse Mode: Ideal for teeth and gum massage, promoting gum health.
The device features a memory function that records the last used mode, so you don't need to adjust it each time.

Using the Water Flosser
Once the tank is filled and the nozzle is attached, place the nozzle tip into your mouth, aiming it at the gumline at a 90-degree angle. Lean over a sink to avoid splashing. Press the 'On/Off' button to start the water flow. Guide the water jet along your gumline and between your teeth, pausing briefly between each tooth. The 360° rotatable nozzle allows you to reach all areas effectively. Continue until you have cleaned all areas of your mouth. The device is highly effective at removing 99.99% of food debris and plaque.

Maintenance and Cleaning
Cleaning the Water Tank
After each use, empty any remaining water from the tank. Detach the tank and rinse it thoroughly with clean water. For a deeper clean, you can use a mild soap solution and then rinse completely. Allow the tank to air dry before reattaching or storing.
Cleaning Nozzles
Remove the nozzle after each use and rinse it under running water. Periodically, you can soak the nozzles in a solution of 2 parts water to 1 part white vinegar for 5-10 minutes to remove mineral deposits, then rinse thoroughly.
Cleaning the Main Unit
Wipe the exterior of the main unit with a soft, damp cloth. Do not use abrasive cleaners or immerse the main unit in water.

Store the water flosser in a cool, dry place away from direct sunlight. Ensure the water tank is empty and dry before storing for extended periods. Use the provided storage bag for convenient and hygienic travel or storage.
