READ ALL PRECAUTIONS AND INSTALLATION INSTRUCTIONS CAREFULLY.
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).
• Protect unit from freezing.
• 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.
• Do not install the unit on its side. It
must be installed upright to maximize
contact with media bed.
• 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 sequence of equipment will
affect performance and could damage
your system.
