Parts identification
Note
There may be moisture inside the main unit (water tank and suction hose). This is moisture left from the distilled water used for product testing and is hygienically safe.
Charging
► On the bathroom countertop or a shelf
-
Place the cord in the right, left or centre cord guide, depending on where the charger will be placed.
-
Place the charger on a secure, level surface.
-
Plug in the power plug.
-
Insert main unit so it stands upright in the charging section.
The charging indicator will light up.- Be sure to place the main unit upright. If the main unit is tilted or not in direct contact with the charger, the main unit may not charge properly.
- Charging is completed in about 15 hours.
- The lamp does not go off even when charging ends.
- The main unit will provide an operation time of approximately 15 minutes of use when the battery is fully charged. (The operating duration will become shorter as the batteries get older.)
-
Disconnect the power plug after charging is completed.
- The battery performance will not be affected even if it is charged for more than 15 hours.
Notes
- When using the appliance for the first time or if it has not been used for more than half a year, the charging indicator may not light up for several minutes after charging starts or the operating time may become shorter. In such cases, charge the battery for 23 hours or more.
- Recommended ambient temperature for charging is 5 – 35 °C. Battery performance may decrease under extremely low or high temperatures, and the battery may not charge properly.
How to use
1. Attach the nozzle firmly onto the main unit.
2. Open the water tank cap, hold the main unit so it is level, and fill the tank with water.
- Always use new tap water or lukewarm water.
- If the water feels cold, use lukewarm water with a temperature of 40 °C or less.
3. Close the water tank cap, making sure it locks in place.
4. Press the mode switch and select the desired water jet mode.
- The mode indicator will glow the previously selected mode. If the appliance is not used for more than 30 days, or after the appliance has been fully charged from its fully discharged state, the mode is initialized to air in (soft). (When the battery is drained, the mode will be reset but this is not a fault.)
- If you want to use a different mode, press the mode switch until it changes to the desired setting. Pressing the mode switch will change the mode from air in (soft) to air in (normal) to jet.
Notes
- When you use the appliance for the first time, press the power switch to turn the appliance on and test each of the water jet modes with the tank filled with water.
- We recommend using the appliance in an ambient temperature range of 5 – 35 °C. If used outside this range, the appliance may stop operating.
- Do not hold the tip of the nozzle firmly against the teeth or gums.
- Do not operate the main unit when empty other than when pouring out any remaining water after use. Operating the main unit without water may result in a malfunction.
5. Place the nozzle in your mouth and close your mouth gently before pressing the power switch.
- To use, place your face over a washbasin, and with the main unit upright and the nozzle at the top, raise your elbow.
- Pressing the mode switch during use will change the mode.
- A fully filled water tank provides approximately 35 seconds of use.
- If the nozzle is inclined too much, water will come out of the ventilation hole instead of the nozzle. (The ventilation hole in the rear of the main unit allows for easier water suction of the hose.)
Turn the nozzle handle to adjust the direction of the water flow.
6. After use, press the power switch to turn off the main unit.
- Stop operation with the nozzle still in the mouth to prevent water from splashing.
► Cleaning the space between the teeth
In the jet mode
- Direct the water flow onto the zone between the teeth.
- Direct from the front and back sides of the teeth.
► Periodontal pocket cleaning
In the air in (normal) mode
- Aim the water flow at the space between the teeth and gum.
- Slowly shift the water flow along the gum.
- Clean the front and back of the teeth and behind the molars as well.
- Clean the areas of concern in the gum in the air in (soft) mode.
- Do not clean the periodontal pocket in jet mode, since the strength of water flow is too strong.
► Gum care
In the air in (normal) mode
- Stimulate the gum.
- Gently stimulate the areas of concern in the gum in the air in (soft) mode.
After use
Open the water tank cap and pour out the water.- Always pour out the remaining water and empty out the water tank. If water is left behind, this may result in the growth of bacteria.
- Turn on the power switch and drain out the water.
- Operate for 2-3 seconds until no more water appears and then turn off the power switch.
- Stand the main unit in the charger.
- While pressing the nozzle release button, remove the nozzle from the main unit and place it on the nozzle stand.
Cleaning
-
Pull out the water tank downwards.
-
Clean with water.
- Remove the identification ring and clean with water.
- Do not wash with hot water exceeding 50 °C.
- If using a detergent, use one suitable for dishwashing. Rinse well with water to ensure no detergent remains after cleaning.
- Never use thinners, benzine, or alcohol since it may cause malfunction or cracking/discoloration of the parts.
**Scrub the filter at the tip of the suction hose lightly with a soft brush.
**
- Wipe away the water with a towel etc. and dry.
- Align and slide the water tank along the groove and install it securely.
Use a cloth to wipe away the stains on the charger.
* Never use thinners, benzine, or alcohol since it may cause malfunction or cracking/discoloration of the parts.
* Do not clean the charger with water.
* About once every six months wipe the prongs of the power plug with a dry cloth.Troubleshooting
