Important Safety Information –
Read All
Caution: Read and follow the information in this
manual to minimize the risk of electric shock or per-
!
sonal injury.
Important: If you are unsure about installing your Watts
water softener, contact a Watts representative or consult a professional plumber.
Important This system must be installed in compliance
with applicable state, province and local codes, law,
and regulations.
READ Instructions Before Using
• Before beginning installation, read these instructions completely.
Then obtain all the materials and tools needed for installation.
NOTE: Failure to install the system correctly voids the warranty.
• Perform installation according to state, province and local plumbing
codes.
Use only lead-free solder and flux for sweat-solder connections,
as required by state, province and federal codes.
• Handle all components of the system with care. Do not drop, drag
or turn components upside down.
• Be sure the floor under the water softening system is clean and
level.
• The system uses 24 volt-60Hz electrical power. Always use the
transformer supplied.
Plug transformer into an indoor 120 VAC, grounded outlet.
Properly ground the system to conform with all codes and ordi-
nances.
• Install the system in a protected area. Be sure electric outlet and
transformer do not come in contact with water. See Where to
Install the Softener, in the installation section of the manual.
Do not attempt to treat water over 110°F (43°C) with the sys-
tem. Always connect the system to the main water supply pipe
before 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 20 psi. Maximum inlet water pressure is 125 psi. Use a pressure reducing valve if necessary.
• Sodium used in the water softening process should be considered
as part of your overall dietary salt intake. Contact physician if you
are on a low sodium diet.
• Use clean water softening salts only, at least 99.5% pure. Failure
to use the correct salt may create a health hazard or maintenance
problems.
Use nugget, pellet or coarse solar salts.
Do not use rock, block, granulated or ice cream making salts.
• Always keep the salt lid in place unless servicing the unit or replenishing salt.
Caution:
• Do not use with water that is microbiologically
!
unsafe or of unknown quality.
• Test the water periodically to verify that the
system is performing satisfactorily.
• Discard small parts remaining after the installation.

Setup
Unpack and check the system components for damage or missing
parts.
Where to Install the Softener
Consider the following points when determining where to install the
water softener:
• Place the system as close as possible to a sewer drain.
• Do not install the softener where it would block access to the water
heater, or access to the main water shutoff, water meter, or electrical panels.
• Keep outside faucets on hard water to save soft water and salt.
• Install the softener in a place where water damage is least likely to
occur if a leak develops.
• A 120VAC electrical outlet is needed to plug in the transformer. If
the outlet is remote (up to 100 feet), use 18 gauge wire to connect.
• 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.
Determine Hardness Setting
Municipal Water
It is recommended that you call your local water company to determine your water hardness in grains per gallon and iron in mg/l (or
ppm).
Well Water
It is recommended that you have your water tested professionally for
accurate hardness and iron content.
