Prime Unit (First Time Use Only)
Set the pressure control dial on base to high (pressure setting No.10), point the handle and tip into sink. Turn power and water ON until water flows from the tip. Turn unit OFF.

Adjusting the Pressure Setting
Turn the pressure control dial on the base of the unit to the lowest setting (pressure setting No.1) for first-time use. Gradually increase pressure over time to the setting you prefer – or as instructed by your dental professional.

Using the Water Flosser
Always place the tip in your mouth before turning the water ON. With water switch on the handle in OFF position, turn power on. Lean over sink and slightly close your lips enough to prevent splashing while still allowing water to flow from your mouth into the sink. Turn water switch ON. When finished, turn water switch and power OFF. During use you can stop the flow of water by sliding the water switch on handle to the OFF position.

NOTE : Engine will continue to run.

Recommended Technique
For best results, start with back teeth and work toward the front teeth. Direct the stream at a 90-degree angle to your gumline with tip in mouth. Glide tip along gumline and pause briefly between teeth. Continue until you have cleaned the inside and outside of both the upper and lower teeth. Lean over sink.

When Finished
Turn the unit OFF. Empty any liquid left in the reservoir. Unplug the unit.

NOTE : If you used mouthwash or other solution besides water, see the “Using Mouthwash and Other Solutions” section.

TIP USAGE
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. Turn the water switch OFF on the handle. Place the soft tip against a tooth at a 45-degree angle and gently place the tip under the gumline, into the pocket. Turn on power on base and water switch on handle ON.

Tongue Cleaner Tip
To use the tongue cleaner tip, set it to the lowest pressure setting, place tip in the center/middle of your tongue about halfway back and start the Water Flosser. Pull forward with light pressure. Increase pressure as you prefer.

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

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 tip along the gumline, pausing briefly between teeth to gently brush and allow the water to flow between the teeth

CLEANING AND TROUBLESHOOTING YOUR WATERPIK WATER FLOSSER

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

Cleaning
Before cleaning, unplug from the electrical outlet. Clean the product when necessary by using a soft cloth and mild non-abrasive cleanser. The accessory storage container and the water reservoir are removable for easy cleaning and are top rack dishwasher safe.

Removing Hard Water Deposits
Hard water deposits may build up in your unit, depending on the mineral content of your water. If left unattended, it can hinder performance. Cleaning internal parts: add 2 tablespoons of white vinegar to a full reservoir of warm water. Point the handle and tip into sink. Turn unit ON and run until 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.

Leakage
If leaking due to a damaged hose, replacement hoses and handles can be purchased at www.waterpik.com or contact Water Pik Inc. customer service for a self-service repair kit.
