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.
■
I
t is highly recommended that a water shut off valve
be placed directly upstream of your household filter.
PROPER INSTALLATION
■
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-todrink, 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.
This Household Filtration System must be properly installed and located in accordance with the Installation Instructions before it is used.
System is
Tested and Certified by NSF
International against ANSI/NSF
Standard 42
for Particulate Reduction Class III.

ABOUT THE FILTER CARTRIDGE
Filter Cartridge Replacement
You should change your filter when the water flow is noticeably reduced or at least every three months.
Filter Cartridge Life
Several variables determine how long the
cartridge will last in your Household
Water Filtration System. These include:
■
levels of sediment or other undesirable
substances in your water.
■
the amount of water you use.
■
the filter location (filtering all or part of
household water).

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.

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.
Press the red pressure release button to
remove trapped air.
Open any downstream faucet and allow filter
