Operating Instructions

1. First Use (Priming Unit)

For first-time use, or if the unit has not been used for an extended period, prime the unit:

• Fill the reservoir with warm water.
• Point the tip into the sink.
• Turn the unit ON to the highest pressure setting until water flows from the tip.

2. Daily Use

1. Lean over a sink and place the tip in your mouth.
2. Turn the unit ON.

Maintenance

Cleaning the Unit

• After each use, empty any remaining water from the reservoir.
• Wipe the exterior of the unit with a soft, damp cloth.

• Do not immerse the main unit in water beyond its IPX-7 rating.

Tip Care

• Clean tips as needed by rinsing them under warm water.
• Replace jet tips every 3 months for optimal performance and hygiene.

Troubleshooting

• No Water Flow: If water does not come out after connecting the tip:
  1. Remove the tip.
  2. Pour a few drops of water into the connection point between the tip and the main unit.
  3. Reconnect the tip and check for water flow.
  4. Alternatively, fill the tank with water and shake the main unit several times to help prime the pump.
