• Pik Pocket™ Tip: Specifically designed to deliver water or anti-bacterial solutions deep into periodontal pockets. 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. Turn the unit on and continue tracing along the gumline.
• Tongue Cleaner Tip: Set to lowest pressure setting. Place tip in the center/middle of your tongue about halfway back. Start the Water Flosser. Pull forward with light pressure. Increase pressure as you prefer.
• Orthodontic Tip: Gently glide tip along gumline, pausing briefly to lightly brush area between teeth and all around orthodontic brackets, before proceeding to the next tooth.

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 to prevent clogging 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

• 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

Add 1 tablespoon of white vinegar to a full reservoir of warm water. Point the handle and tip into a sink. Turn the unit ON and run until the reservoir is empty. Rinse by repeating with a full reservoir of clean warm water.

Battery Care and Disposal

The unit will not charge if the switch is in the ON 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. At the end of the battery life, please recycle the unit at your nearest recycle center per local or state requirements. The battery is not replaceable.
