Before You Begin

WARNING: Risk of personal injury. Do not use with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system.

CAUTION: Risk of property damage. Do not install the unit where the temperature may drop below freezing, may be exposed to direct sunlight, or may be exposed to heat.

NOTICE: Read this entire manual thoroughly to prevent personal injury and property damage during installation and use of this product.

NOTICE: Check with your local public works department for plumbing code requirements. Follow their guidelines as you install this water ﬁltration system.

NOTICE: This product has a limited service life. Keep a record of the date of installation and any other performed maintenance. Because of the limited service life, and to prevent costly repairs or possible water damage, replace the system every 10 years.

NOTICE: Turn off the water supply to the ﬁlter head, and remove the ﬁlter cartridge if it will be unattended for an extended period of time (approximately 4 weeks or more). Store the ﬁlter cartridge in a sealed bag in the refrigerator to maximize the remaining ﬁlter capacity.

NOTE: Make sure that the mounting location and fastening hardware will support the system when installed and full of water.

Before You Begin (cont.)

Observe all state and local plumbing and building codes.

Contaminants or other substances removed or reduced by this ﬁltration system may not be present in your water. Refer to the Performance Data Sheet (included) for contaminants and reduction performance.

Inspect the plumbing and supplies for damage. Repair or replace as needed.

Install the water ﬁltration system to a cold water supply only. Do not install the system to a hot water supply.

The water ﬁltration system is designed to be installed beneath a sink. Make sure that the bottom of the ﬁlter cartridge is at least 2″ (51 mm) above the ﬂoor of the cabinet, and will be accessible for ﬁlter cartridge replacement after installation.

Replace the ﬁlter cartridges every 6 months, when the capacity has been exceeded, or when a noticeable decrease in water ﬂow is observed.

Flush the ﬁlter system thoroughly after prolonged periods of nonuse. Allow the water to ﬂow for 5 or 6 minutes before use.

This system connects to a 3/8″ (9/16″-24 UNEF-2A) compression connection. Special ﬁttings may need to be purchased to accommodate other connections.

Record your model number and installation date below. Also mark the installation date on the ﬁlter head and ﬁlter cartridges. Model number: ____________ Replacement date: _____________

Keep this manual for future reference.

1. Prepare the Site

For existing installations: Turn off the cold water supply, and turn on the faucet to relieve water pressure and drain water from the line.

Disconnect the cold water supply line from the cold water supply valve.

NOTICE: Use care to avoid overtightening or cross-threading the connections to prevent water leakage.

If both ﬁltered and unﬁltered water will be supplied, install the tee (provided) to the cold water supply valve.

Connect the water supply adapter to the cold water supply valve or the tee.

2. Mount the Filter Head

IMPORTANT! This unit is designed for vertical installation.

IMPORTANT! The mounting location of the water ﬁltration system is critical. Verify that the bottom of the ﬁlter cartridge will be at least 2″ (51 mm) from the ﬂoor of the cabinet. Ensure that the system will not interfere with other items and will be easily accessible. Make sure that the tubing will not be under tension when installed.

NOTICE: Select mounting fasteners (not provided) appropriate for the cabinet wall material.

Align the mounting holes of the ﬁlter head at the determined mounting location.

Mark the mounting-hole locations with a permanent marker. Set the ﬁlter head aside.

Predrill the mounting holes, if necessary, based upon the fasteners selected.

Partially thread the fasteners into the cabinet wall, and slide the ﬁlter head over the fasteners.

Secure the ﬁlter head in position by tightening the fasteners.

3. Connect the Tubing

CAUTION: Risk of property damage. Do not damage, kink, or crimp the tubing. Avoid cutting the tubing. If it is necessary to cut the tubing, use a sharp utility knife to make a clean and square cut to avoid water leakage.

IMPORTANT! Water from the supply line must be connected to the ﬁlter head inlet. Water from the ﬁlter head outlet must be connected to the faucet. System performance and ﬁlter capacity will be compromised if connected incorrectly.

Wet the end of one of the tubing sections with water, and press it ﬁrmly into the inlet port of the ﬁlter head.

Wet the other end of the tubing with water, and press it ﬁrmly into the water supply adapter.

Repeat for the other tubing section, pressing one end into the outlet port of the ﬁlter head. Press the remaining end into the ﬁltered water faucet adapter.

Connect the ﬁltered water faucet inlet to the ﬁltered water faucet adapter.

If used, connect the unﬁltered water faucet inlet to the tee.

Press the cover onto the ﬁlter head.

If desired, secure the tubing to a cabinet wall using appropriate clamps and hardware (not provided).

4. Install the Filter Cartridge

IMPORTANT! For the K-77686: Two identical ﬁlter cartridges are used. For future ﬁlter cartridge replacement, replace both cartridges at the same time to maintain proper performance.

Write the installation date on the new ﬁlter cartridge label.

Remove and discard the cap from the ﬁlter cartridge.

Inspect the ﬁlter cartridge for damage.

Verify that both sets of O-rings are present and are positioned correctly in the grooves.

NOTE: The ﬁlter cartridge will only engage into the ﬁlter head one way. Do not force the components.

Align the ﬁlter cartridge so the label is to the left, and press upward so the ﬁlter cartridge key engages into the ﬁlter head.

Use your hand to rotate the ﬁlter cartridge counterclockwise 90° until it stops and is securely engaged into the ﬁlter head.

5. Installation Checkout

Turn on the cold water supply and check all connections for leaks. Repair as needed.

Run water through the faucet for at least 5 minutes to remove any air and carbon particles in the system.

Maintenance

Routine maintenance and ﬁlter cartridge replacement will not require that the tubing be disconnected. Follow this procedure if it becomes necessary to disconnect the tubing from the ﬁttings.

•Turn off the cold water supply to the ﬁltration system, and turn on the faucet to relieve water pressure.

•Firmly press in the collar around the ﬁtting while using your hand to pull the tubing free.

•Inspect the tubing for damage or crimping.

•Refer to the ″Connect the Tubing″ section to reinstall the tubing.

•Refer to the replacement ﬁlter cartridge installation instructions to replace the ﬁlter cartridge.

exécuté. En raison de la durée de vie utile limitée, et pour empêcher des réparations coûteuses ou des dégâts d’eau éventuels, remplacer le système tous les 10 ans.

AVIS: Couper l’alimentation en eau à la tête du ﬁltre et retirer la cartouche du ﬁltre si on ne s’en occupe pas sur une période prolongée (4 semaines environ ou plus) Entreposer la cartouche du ﬁltre dans un sac scellé dans le réfrigérateur aﬁn de porter au maximum la durée de vie restante du ﬁltre.

REMARQUE: S’assurer que l’emplacement de montage et la visserie de ﬁxation pourront supporter le système lorsque celui-ci est installé et rempli d’eau.

Respecter tous les codes de plomberie et de bâtiment de l’État et locaux.

Les contaminants ou d’autres substances retirées ou réduites par ce système de ﬁltration pourraient ne pas être présents dans votre eau. Consulter la ﬁche technique sur la performance (incluse) en ce qui concerne les contaminants et la performance de réduction.

Inspecter la plomberie et les accessoires pour y rechercher des dommages éventuels. Réparer ou remplacer selon les besoins.

Installer le système de ﬁltration d’eau sur une alimentation en eau froide seulement. Ne pas installer ce système sur une alimentation en eau chaude.

Le système de ﬁltration d’eau est destiné à être installé au-dessous d’un évier. S’assurer que le fond de la cartouche du ﬁltre se trouve à 2 po (51 mm) au moins au-dessus du plancher du meuble et qu’il sera accessible pour le remplacement de la cartouche du ﬁltre après installation.

Remplacer les cartouches de ﬁltre tous les 6 mois, lorsque la capacité a été dépassée, ou lorsque l’on observe une réduction perceptible dans le débit d’eau.

Purger le système du ﬁltre au complet après des périodes prolongées de non utilisation. Laisser l’eau s’écouler pendant 5 ou 6 minutes avant utilisation.

Ce système se connecte à un connecteur de compression de 3/8 po (9/16 po-24 UNEF-2A). Il sera peut-être nécessaire d’acheter des raccords spéciaux pour s’adapter à d’autres connexions.
