How to Use

Plug the wire into the socket. If the socket is controlled with a switch on the wall, make sure it is on. The product handle has a power-on/off button, pause button, two pressure control buttons and a switch between super oxygen water and natural water on the front, of which the pressure control button can be used to control the water pressure. After plugging-in, the screen in the center of the body will show the operation status; press the power-on button, and then the screen will show ten levels from 01 to 10. The user may select a proper level to control the water pressure. The user may select the super oxygen water (for disinfection) by pressing the switch between super oxygen water and natural water. Set a 3-minute operation from start to halt (note: The product needs to restart after the timer is over).

Prepare the Water Tank

Take off the water tank, fill it with warm water, put on and tightly press the water tank cover. The sound of cracking means the installation is complete. The tank surface has volume marks in the unit of OZ. and ML.

Insert and remove the nozzle

Insert the nozzle into the middle of the knob at the top of the handle of the water flosser. If the nozzle is locked in place, the colored ring shall be flush with the end of the knob. To remove the brush from the handle, please press the nozzle eject button and pull the nozzle out of the handle.

Adjust pressure settings

When using the product for the first time, please adjust the pressure gear on the handle of the product to the minimum value (the gear displayed on the body can be adjusted in gears 01-10). Start from the lowest gear, turn on the switch on the handle, and gradually increase the pressure after the oral cavity adapts to it. You can also increase the pressure under the guidance of a professional dentist.

Using Oral Irrigator

Lean over the sink and place the injector head into the mouth. Align the nozzle to your teeth. Turn on the pushing switch on the handle to adjust the water pressure to the desired value. Control the direction of water flow
by turning the knob on the top of the handle.

Use Tips

Adjust the water jet flow to 90 degree to the gum line. Close your lips to prevent the water from flowing sideways while allowing the water in your mouth to flow freely into the sink. For best effect, start cleaning from the molar teeth (back teeth) towards the front teeth. Slide the injector head along the gum line with short pauses between teeth. DO NOT stop until the areas around the gums and among the teeth are cleaned.

Pause Control

You can turn off the oral irrigator at any time and then put the handle back on to pause the water flow.

Completion

Turn off the device, pour out the residual liquid in the water tank and unplug the device. The device automatically starts the previous configuration after power-on.

Note: The device bottom has a drain hole for the drainage of the water tank and main body. It is not a water leakage.

Instructions for the Jet Tip

High-pressure tip

360° washing and cleaning covers the area that normal toothbrushes can not reach. It is more effective than dental floss and healthier for your gum.
Periodontal pocket tip
It can inject water or antibacterial liquid to the specific part under your gum. Please bend on the basin, reach the soft tip to your teeth at an angle of 45°, and then slightly put the tip in the alveolar socket under the gum line. Turn on the device, set the minimum pressure level, slightly put the tip to the tooth slit and start cleaning teeth along the gum line. Continue moving along the gum line until the cleaning is complete.
Tongue scraper
Bend on the sink. Put the tongue scraper on your tongue and turn on the oral irrigator (start by the minimum level and make gradual adjustment). Slightly put the scraper at the center of the tongue back and then scrape forward.

Orthodontic tip
The professional orthodontic tip aims to clean the parts around the braces and those cannot be reached by a dental kit. Bend on the sink and clean with the tip to wash off the residues on your teeth.

Dental plaque tip
Aim at your gum with the water flow at a 90° angle, slightly close your lips to avoid splashing and make sure the water flows in the sink. Start from the back of molar and then to the front. Put the tip close to your teeth so that the brush can slightly touch your teeth. Keep the tip slowly moving along the gum, and pause between teeth for a while to make sure the water flows through. Repeat the same operations on each side of teeth until all the teeth are cleaned.

Cleaning

If any special liquid will be filled in the water tank, please clean the tank in advance. Inject some warm water in the water tank. Point the jet tip to the sink. Turn on the device until the tank is empty. It will help avoid tip blockage and prolong the service life of the device. The device shall be cleaned with a soft cloth and neutral wear-free detergent. Do remember to unplug the device before cleaning. Take off the water tank and start operating the oral irrigator until no residue can be found in it.

Maintenance

1. Unplug the device after cleaning is completed, place the water tank upside down on a plate until it is totally dry, and then keep it with the clean body at a cool and dry place. It shall be kept in a package or appropriate paper box in case of long-term storage.
