If you are unsure about installing your Watts water filter, con-
tact a Watts representative or consult a professional plumber.
Observe all local plumbing and building codes when installing
the system
Important Safety Information – Read All
IMPORTANT
Test the water periodically to verify that the system is perform-
ing satisfactorily.
Discard small parts remaining after the installation.
CAUTION
!
NOTICE
Failure to install the system correctly voids the warranty.
Handle all components of the system with care. Do not drop,
drag or turn components upside down.
Be sure the floor under the water filter system is clean, level and
strong enough to support the unit.
WARNING
!
Install the system in a protected area.
For more informa-
tion on where to install the filter see the Installation Consid-
erations section of this manual.
• Do not attempt to treat water over 110°F (43°C) with the
system. Always connect the system to the main water sup-
ply pipe before the water heater.
• Do not expose the system to freezing temperatures. Water
freezing in the system causes equipment damage.
• Do not install in direct sunlight. Ultraviolet rays from the
sun may cause damage.
• Minimum inlet water pressure is 30psi. Maximum inlet
water pressure is 125psi.
• System must operate in the vertical position, do not lay
down during operation
• Place system on a smooth, level surface
• A by-pass valve is include and must be installed on every
system to facilitate installation and service
• Water known to have heavy loads o fdirt and debris should
be pre-filtered usinga 20 micron filter cartridge model
number PWPL10FFM20 and 1” high flow housing kit model
number PWHIB10FF.
• If making a soldered copper installation, do all sweat sol-
dering before connecting pipes to the bypass valve. Torch
heat will damage plastic parts.
• When turning threaded pipe fittings onto plastic fittins, use
care not to cross thread
• Use PTFE tape on all external pipe threads. Do not use pip
joint compound
• Support inlet and outlet plumbing in some manner (use of
pipe hangers or similar) to keep weight off of the bypass
fittings.

*Note:
Peak service flow rate is for intermittent use only and is not to be interpreted as con-
tinuous service flow rate capability. These systems are designed to treat the domestic water
used in a single family dwelling. For irrigation water treatment or higher volume applications
please contact your Watts representative. Peak service flow rates are based on a 15psi drop.
Optimum service flow rate is specific to water chemistry and will vary.
Installation Considerations
NOTICE
Prior to start up, fill tank with water and allow carbon media
to soak for 24 hours to assist with flushing carbon fines from
mineral tank during start up.
Consider the following points when determining where to install
the filter:
• Do not install the filter where it would block access to the water
heater, or access to the main water shutoff, water meter, or electri-
cal panels .
• Install the filter in a place where water damage is least likely to oc-
cur if a leak develops .
• Always connect the system to the main water supply pipe before
the water heater .
• Install the system where it will not be subject to temperatures
outside of the limits stated in the Specification section or to direct
sunlight .
• Make sure the installation surface is smooth, level, and sturdy
enough to support the weight of the wetted system .
