PRECAUTIONS
When installing:
• Properly tighten all fittings to ensure a
leak-free assembly.
• Allow a minimum of 2-1/2" clear space
below unit to facilitate filter change.
• Pipe and filter need to be properly
supported with pipe hangers.
• If installing on metallic plumbing, two
grounding clamps and #4 copper wire
are essential for safety.
Before installing:
• Do not install this filtration system
where the line pressure may exceed
100 psi. The operating pressure range
for this filtration system is between
25 psi – 100 psi.
• Install on cold water lines only
(40° – 100°F).
• Do not install the unit on its side. It
must be installed upright to maximize
contact with media bed.
• 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.
• Installation of the filtration system
must comply with existing state and
local plumbing codes. A. O. Smith
and its manufacturer is not liable for
consequential or incidental damages
due to improper installation.
• Some local codes may require the
use of a licensed plumber or certified
installer when disrupting a potable
water line.
• Due to the varieties of home design,
not all installation configurations can
be addressed in this guide.
• Improper sequencing of equipment will
affect performance and could damage
your system.
READ ALL PRECAUTIONS AND INSTALLATION INSTRUCTIONS CAREFULLY.
Do not use with water that is microbiologically
unsafe or of unknown quality without adequate
disinfection before or after the system.
Ensure operating pressures are within filter
housing specifications. Some installations may
require a pressure reducer installed before filter
system to reduce operating pressures.
For use with cold water only.
