Getting Started

Charging the Unit:

Plug the charger into the electrical outlet and the cord into the charging inlet. Make sure the switch is in the OFF (0) position before charging. The unit will not charge if the switch is in the ON (I) position. The Waterpik® Water Flosser will stay charged for up to 2 weeks depending on use.

Filling the Reservoir:

Remove the charger from the unit prior to filling the reservoir and product use. Lift the flip-top on the reservoir and fill with lukewarm water.

Inserting and Removing Tips:

Insert the tip into the center of the knob at the top of the Water Flosser handle. Press firmly until the tip clicks into place. To remove the tip from the handle, press the tip eject button and pull the tip from the handle.

CAUTION: Do not press the tip eject button while the unit is running.

Adjusting the Pressure Setting:

You can adjust the pressure setting on your Water Flosser by sliding the pressure control on the handle. Start with the lowest setting and increase to your liking.

Recommended Technique:

Lean low over a sink and place the tip in your mouth. Aim the tip toward the gumline, and turn the unit ON (I). For best results, start with the back teeth and work toward the front teeth. Glide the tip along the gumline, pausing briefly between teeth. Continue until you have cleaned the inside and outside of both the upper and lower teeth. Direct the jet stream at a 90-degree angle to your gumline. Slightly close lips to avoid splashing, but allow water to flow freely from mouth into the sink. Keep the unit upright during use for best results.

When Finished:

Turn the unit OFF (0). Empty any liquid left in the reservoir. If desired, the reservoir may be removed from the power handle by sliding the reservoir release latch to the unlock position and then sliding the reservoir down towards the base of the unit.

Tip Usage Details

Pik Pocket™ Tip:

The Pik Pocket™ tip is specifically designed to deliver water or anti-bacterial solutions deep into periodontal pockets. To use the Pik Pocket™ tip, set the unit to the lowest pressure setting. Place the soft tip against a tooth at a 45-degree angle and gently place the tip under the gumline, into the pocket.

Tongue Cleaner Tip:

Set to lowest pressure setting, place the tip in the center/middle of your tongue about halfway back. Pull forward with light pressure. Increase pressure as you prefer.

Orthodontic Tip:

To use the orthodontic tip, gently glide the tip along the gumline, pausing briefly to lightly brush the area between teeth and all around orthodontic brackets, before proceeding to the next tooth.

Toothbrush Tip:

Place the toothbrush tip in your mouth with the brush head on the tooth at the gumline. The toothbrush tip can be used with or without toothpaste. Use light pressure (bristles should not bend) and massage the brush back and forth with very short strokes – much like you would with a manual toothbrush.

Plaque Seeker™ Tip:

To use the Plaque Seeker™ tip, place the tip close to the teeth so that the bristles are gently touching the teeth. Gently glide the tip along the gumline, pausing briefly between teeth to gently brush and allow the water to flow between the teeth.

Cleaning and Troubleshooting

Using Mouthwash and Other Solutions:

Your Waterpik® Water Flosser can be used to deliver mouthwash and antibacterial solutions. After using any special solution, rinse the unit by partially filling the reservoir with warm water and running the unit with the tip pointed into a sink until the unit is empty.

Cleaning the Unit:

Never immerse the unit in water. Before cleaning, unplug from the electrical outlet. Clean the product when necessary by using a soft cloth and mild non-abrasive cleanser to wipe the exterior. The water reservoir is removable for easy cleaning and is top rack dishwasher safe. It is recommended that the reservoir is removed and cleaned weekly.

Removing Hard Water Deposits / General Cleaning:

Hard water deposits may build up in your unit, depending on the mineral content of your water. If left unattended, it can hinder performance. To clean internal parts: add 1 tablespoon of white vinegar to a full reservoir of warm water. Point the handle and tip into a sink. Turn unit ON and run until the reservoir is empty. Rinse by repeating with a full reservoir of clean warm water. This process should be done every 1 to 3 months to ensure optimal performance.

Battery Care:

The unit will not charge if the switch is in the ON (I) position. If you use your Water Flosser once a day or less, it is recommended you charge it overnight, once a week. If you use it twice a day or more, charge the unit more frequently. Do not run the batteries down completely as this may shorten the lifespan of the batteries and will require charging the unit for 24 hours to obtain a full charge. If the Water Flosser is to be stored for an extended period of time (six months or more), be sure to fully charge it prior to storage. The unit contains a Nickel Metal Hydride battery.

Battery Removal

The product contains battery and/or recyclable electronic waste. In order to protect the environment, please do not dispose along with household waste.
