Description

Because of its robust construction and ergonomic design, the Water Flosser WP-660 is guaranteed to fit easily in your hand. Depending on your preference, you can fill the device's spacious 600 ml water tank with either warm or cold water. It has seven replaceable tips, each of which is intended for a certain oral hygiene function, such as cleaning around orthodontic braces or focusing on areas that are prone to plaque.
With its ten pressure-setting options, the WP-660 lets you modify the flow to your preferred level of comfort. Those with sensitive gums or those who are new to using a water flosser will find this feature especially helpful. It is appropriate for morning and evening rituals because of its quiet operation, which guarantees little disruption while in use.

GETTING STARTED

Powering the Unit 
Plug the cord into an electrical outlet. If the outlet is controlled by a wall switch, be sure it is turned on.

Preparing the Reservoir 
Lift the reservoir lid, remove the reservoir, and fill with lukewarm water. Replace the reservoir over the base and press down firmly and close the lid.

Inserting and Removing Tips 
Insert tip into the center of the Water Flosser handle, pressing down firmly until the tip clicks into place. The colored ring will be flush with the top of the handle if the tip is correctly locked into place. To remove tip from the handle push the tip eject button on the handle.

Prime Unit (First Time Use Only) 
Set 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 handle in OFF position, turn power on. Lean over sink and slightly close lips enough to prevent splashing while still allowing water to flow  from 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: Motor will continue to run.

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.

One-Minute Timer/30-second Pacer (Floss Mode Only) 
The Water Flosser will create a short pause at 30-seconds, to remind you to move to the other arch of your mouth and another short pause at 1-minute to signal you have reached the recommended cleaning time. The unit will continue to run without pauses until the unit is turned off. Depending on the pressure setting, some water will remain in the reservoir after 1-minute.

Timer may be deactivated if desired.

Steps to deactivate:

1. While unit is off, press the mode button once to wake the unit up. 
   One of the LEDs should light up.
2. Press and hold the mode button for approximately 3-seconds until the Massage Mode light blinks. The timer is now deactivated.

If you wish to reactivate the timer:

1. While unit is off, press the mode button once to wake the unit up. One of the LEDs should light up.
2. Press and hold the mode button for approximately 3-seconds until the Floss Mode light blinks. The timer is now activated.

Or unplug unit to reset to factory settings.

Hydro-Pulse Massage Mode

Hydro-Pulse Massage offers a unique water pulsation pattern designed to enhance gum stimulation. For best results, use the Floss Mode as instructed. After using Floss Mode for 1-minute, switch the unit to Massage Mode, adjust pressure as desired, and aim the water stream at your gums and massage throughout your mouth.

To determine in which mode the unit is set while it is off simply press mode button and the LED light will indicate current mode. To change mode, press mode button again. You may also press the mode button while unit is on to change the mode during use.

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

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

NOTE: NOT ALL TIPS INCLUDED WITH ALL MODELS.

Waterpik White Aquarius Water Flosser WP-660 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.

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

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. 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.

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.

Setup Guide

Use these procedures to configure and run the Waterpik White Aquarius Water Flosser WP-660:

1. Pour either cold or warm water into the reservoir.
2. Attach the tip to the end of the flosser handle after selecting the one that best suits your mouth hygiene requirements.
3. Aim for the gum line with the tip in your mouth.
4. Activate the gadget and change the pressure setting as necessary.
5. To guarantee complete cleaning, gently slide the tip along your teeth and gums, stopping momentarily at each stage.
6. Rinse the tip under running water after use, then put it away in the included travel case.
