PERFORMANCE DATA SHEET Model: XWF or XWFE
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.
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.
