!
Read this Manual BEFORE using this equipment.
Failure to read and follow all safety and use information
can result in death, serious personal injury, property
damage, or damage to the equipment.
Keep this Manual for future reference.
You are required to consult the local building and plumbing
codes prior to installation. If the information in this manual
is not consistent with local building or plumbing codes, the
local codes should be followed. Inquire with governing
authorities for additional local requirements. Use only
lead-free solder and flux for sweat-solder connections, as
required by state, province and federal codes.

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.

Installation and Start-up
1. Turn off the main water supply to the home and open an inside
faucet to relieve any pressure within the plumbing system, then
close faucet once pressure is released.
2. Place the system in the desired location. Make sure that the
location is level and sturdy enough to support the weight of the
wetted system.
3. Place the By-Pass Valve in the service position. See image below
for By-Pass positions.
4. Connect the cold water supply to the inlet of the system
5. Install a supply valve (user supplied) in the supply line and close
it.
6. Place a bucket under the outlet port or run a line from the out-
let port to a drain.
7. Turn the water back on to the house. Slowly open the supply
valve to the system. Allow the tank to fill with water. The initial
water will come out black due to the carbon fines in the media
bed.
8. Close the supply valve when a steady stream of clear water
comes out of the outlet port, this could take :05 - :10 minutes.
9. If the outlet is flowing into a bucket, water could splash on
nearby objects. If this threatens the safety, value, structure or
appearance of these objects, protect/remove them or use out-
let hose to drain option.
10. Connect the outlet of the system to the cold water supply of
the home.
11. Slowly open the supply valve to the system
12. Open hot and cold faucets downstream from the system to
relieve any air from the plumbing system and water heaters.
Then close faucets.
13. Inspect for leaks and repair as needed
14. The system is now ready for service
