USE & CARE
3
Read all precautions and installation instructions carefully and completely
before installing.
Precautions
• Properly tighten all fittings to
ensure a leak-free assembly.
• NSF certified plumber's tape (thread
sealing tape) is the only sealer that
can be used on threaded fittings.
DO NOT use pipe dope or PVC
primer/glue on threaded fittings.
Exposure to these compounds will
damage nipples causing leaks.
• Pick an appropriate installation
location. Dimensions of systems
vary—always allow an estimated
minimum of 60” clearance for
height of tank, and a minimum
of 45” for floor space.
• Unit must be installed in an area
where the main water line enters
your home, before connecting to
the water heater.
DO NOT install
after a water heater or on the
hot water line.
• It is recommended your system
be installed indoors and out of
direct sunlight. Prolonged
exposure to light can weaken
plastic components, resulting in
filter housing failure. If this is not
possible and the system is outdoors
or in a sunny area, the unit must be
protected from both direct sunlight
and freezing temperatures.
• If installing on metallic plumbing,
two grounding clamps and #4
copper wire are essential for safety.
• Some local codes may require
the use of a licensed plumber or
certified installer when disrupting
a potable water line.
• In areas with high pressure, a
pressure relief valve and a water
hammer arrestor may be necessary.
Cleaning
The exterior of your filtration
system can be cleaned with warm,
soapy water. Rinse well with fresh,
clean water.
A Pre-Filter is included with your
system. Sediment levels vary from one
location to another. It is recommended
to replace your Pre-Filter every 2
months. If the flow rate has noticeably
decreased, replace your filter cartridge
sooner.
