INSTALLATION INSTRUCTIONS

Household Water Filtration System — GNWH08C

SAFETY PRECAUTIONS

■Check with your state and local public works department for plumbing and sanitation codes. You must follow these guidelines as you install the Household Water Filtration System. Using a qualified installer is recommended.

■Be sure the water supply conforms with the Specifications guidelines. If the water supply conditions are unknown, contact your municipal water company.

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

■It is highly recommended that a water shut off valve be placed directly upstream of your household filter.

PROPER INSTALLATION

This Household Filtration System must be properly installed and located in accordance with the Installation Instructions before it is used.

■Check with your local public works department for plumbing codes. You must follow their guides as you install the Household Filtration System.

■Use the Household Filtration System on a potable, safe-to- drink, home COLD water supply only. The filter cartridge will not purify water or make unsafe water safe to drink. DO NOT use on HOT water (100˚F. max).

■Protect the Household Filtration System and piping from freezing. Water freezing in the system will damage it.

■Your Household Filtration System will withstand up to 125 psi water pressure. If your house water supply pressure is higher than 100 psi during the day (it may reach higher levels at night), install a pressure reducing valve before the system is installed.

■Do not install on HOT WATER. The temperature of the water supply to the Household Filtration System must be between the minimum of 40°F. and the maximum of 100°F. See the Specification guidelines.

■Do not install the Household Filtration System using copper solder fittings. The heat from the soldering process will damage the unit.

WARNING: Discard all unused parts and packaging material after installation. Small parts remaining after installation could be a choke hazard.

■Do not install filter in an outside location or anywhere it will be exposed to sunlight.

Turn off water to filter by rotating the by-pass valve to the by-pass position.

Press the red pressure release button to release pressure.

Unscrew the filter canister and discard used filter. Wash the filter canister with mild soap and water. Do not use harsh cleaners or hot water.

Inspect the filter canister O-ring. Make sure it is lightly lubricated and completely seated in the groove. It is recommended that you replace the O-ring if it is damaged.

Place a new filter cartridge into the canister making sure it is centered and completely seated on the bottom seal.

Reinstall the filter canister to the unit. Hand tightening is all that is required to seal the unit.

Slowly turn on water to the filter by using the by-pass valve.
