INSTALLATION INSTRUCTIONS
Heavy Duty Water Filtration System—GNWH38F
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 Heavy Duty Water Filtration System. Using a
qualified installer is recommended.
■ Be sure the water supply conforms with the Performance Data.
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.
■ Check with your local public works department for plumbing codes.
You must follow their guides as you install the Heavy Duty Water
Filtration System.
■ Use the Heavy Duty Water 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 Heavy Duty Water Filtration System and piping from
freezing. Water freezing in the system will damage it.
■ Your Heavy Duty Water Filtration System will withstand up to
100 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 Heavy Duty Water Filtration System must be
between the minimum of 40°F and the maximum of 100°F.
See the Filter Cartridge Life section.
■ Do not install the Heavy Duty Water Filtration System using
copper solder fittings. The heat from the soldering process
will damage the unit.
■ If making a soldered copper installation, do all sweat soldering
before connecting pipes to the system. Torch heat will damage
plastic parts.
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.
