IMPORTANT
If you are unsure about installing your Watts water filter, contact
a Watts representative or consult a professional plumber.
!
WARNING
Install the system in a protected area. For more informa-
tion on where to install the filter see the Installation Considerations 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 supply 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.
!
CAUTION
Test the water periodically to verify that the system is performing satisfactorily.
Discard small parts remaining after the installation.
Installation Considerations
Consider the following points when determining where to install
the filter:
• Do not install the lter where it would block access to the water
heater, or access to the main water shutoff, water meter, or electrical panels.
• Install the lter in a place where water damage is least likely to occur 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.
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.
