Read all precautions and installation
instructions carefully and completely
before installing
The exterior of your filtration system
can be cleaned with warm, soapy water.
Rinse well with fresh, clean water. Never
use chemical cleaning products on the
system's exterior surface as they may
damage the housing.
A sediment pre-filter for your system
is recommended. Sediment levels vary
from one location to another. If the flow
rate has noticably decreased, a pre-filter
to remove the sediment is usually the
root cause. If you have a pre-filter, once
the flow rate has noticeably decreased
it is time to replace the filter. Allowing
sediment to collect continuously can
cause clogging and restrict the flow of
water into your home. We recommend
replacing your sediment pre-filter
cartridge every 2-3 months.
Precautions
• Do not install this filter where the
line pressure may exceed 100 psi. The
operating pressure range for this filter
is between 20psi – 100psi.
• Install on cold water lines only
(40° – 90°F). Protect unit
from freezing.
• 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.
• 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 inside and out of direct
sunlight. 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 filter must comply
with existing state and local plumbing
codes. A. O. Smith is not liable for
consequential or incidental damages
due to improper installation.
• Improper sequence of equipment will
affect performance, and could possibly
damage your system.
