Recommended Technique
Lean low over sink and place tip in mouth. Aim
the tip toward gumline, and turn the unit ON (I).
For best results, start with the back teeth and
work toward the front teeth. 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.
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 unit upright during use for best results.
When Finished
Turn the unit off. 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(1) and then sliding the
reservoir down towards the base of the unit(2).
To replace the reservoir on the power handle, simply slide it up towards the
top of the unit. The reservoir will snap into place when fully engaged.
Charging Unit Prior to First Use
Plug the cord into any standard electrical outlet. Make
sure you push the switch into the “OFF” position
before charging. The unit will not charge if the
switch is in the “ON” position. See “Battery Care and
Disposal” section for guidance on how to look after
your battery. 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 reservoir and product use. Lift flip
top on reservoir and fill the reservoir with
lukewarm water.
Inserting and Remove Tips
Insert 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 tip from the handle.
CAUTION: Do not press tip eject button while unit
is running.
Adjusting the Pressure Setting
You can adjust the pressure setting on your Water
Flosser by sliding pressure control on the handle.
Start with the lowest setting and increase to
your liking.

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. 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
To use the tongue cleaner tip, set to lowest pressure setting,
place tip in the center/middle of your tongue about half way
back and start the Water Flosser. Pull forward with light
pressure. Increase pressure to your liking.
Orthodontic Tip
To use the Orthodontic Tip, gently glide tip along
gumline, pausing briefly to lightly brush area
between teeth and all around orthodontic bracket,
before proceeding to the next tooth.
Toothbrush Tip
Place the toothbrush tip in mouth with the brush
head on the tooth at the gumline. The toothbrush
tip can be used with or without toothpaste. Turn the
Water Flosser on so the water flows through the tip.
Using a light pressure (bristles should not bend) massage the brush back and
forth with very short strokes-much like you would with a manual toothbrush.
TROUBLESHOOTING YOUR WATERPIK®WATER FLOSSER
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 gumline, pausing briefly between teeth to gently brush and allow the water to flow
between the teeth.
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 sink until unit is empty.
Cleaning
Never immerse 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
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. Cleaning internal parts: add 1
tablespoon 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.

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.
