PERFORMANCE DATA SHEET
NOTICE
To reduce the risk of water leakage or flooding, and
to ensure optimal filter performance:
• Read and follow use instructions before installation and
use of this system.
• Installation and use MUST comply with all state and local
plumbing codes.
• Do not install if water pressure exceeds 120 psi (827
kPa). If your water pressure exceeds 80 psi (552 kPa),
you must install a pressure-limiting valve. Contact a
plumbing professional if you are uncertain how to check
your water pressure.
• Do not install where water hammer conditions may occur.
If water hammer conditions exist you must install a water
hammer arrester. Contact a plumbing professional if you
are uncertain how to check for this condition.
• Do not install on hot water supply lines. The maximum
operating water temperature of this filter system is 100º F
(38º C).
• Protect filter from freezing. Drain filter when
temperatures drop below 33ºF (0.6ºC).
• Change the disposable filter cartridge every six months
or sooner if you observe a noticeable reduction in water
flow rate.
• Failure to replace the disposable filter cartridge at
recommended intervals may lead to reduced filter
performance and cracks in the filter housing, causing
water leakage or flooding.
• This System has been tested according to NSF/ANSI
42, 53, 401 and P473 for the reduction of the substances
listed below. The concentration of the indicated
substances in water entering the system was reduced to
a concentration less than or equal to the permissible limit
for water leaving the system, as specified in NSF/ANSI
42, 53, 401 and P473.
XWF or XWFE System is certified by IAPMO
R&T against NSF/ANSI Standards 42,53, 401
and P473 for the reduction of claims specified
on the performance data sheet and at
iapmort.org.
