CAUTION
• Read and follow Use Instructions before
installation and use of this system.
• Installation and use MUST comply with all state
and local plumbing codes.

plumbing professional if you are uncertain how
to check for this condition.
• Do not install on hot water supply lines. The

filter system is 100 ℉ (37.8 ℃).
• Protect filter from freezing. Drain filter when
temperatures drop below 40 ℉ (4.4 ℃).
• The disposable filter cartridge MUST be replaced
every 6 months, at the rated capacity or if a
noticeable reduction in flow rate occurs.
• To protect it from freezing, remove filter
cartridge when temperatures are expected to
drop below 33 ℉.
• Do not install systems in areas where ambient
temperatures may go above 110 ℉ (43.3 ℃).
• Where a backflow prevention device is installed
on a water system, a device for controlling
pressure due to thermal expansion must be
installed.
• Ensure all tubing and fittings are secure and free
from leaks.

of water (around 1 oz. or 25 cc) to drain.
• Wrap a cloth around the front end of the water
filter cover to collect any leaking water. Hold the
water filter upright, once it is removed, to
prevent any remaining water from spilling out of
the water filter.
