Before You Start
In the state of Massachusetts: The Commonwealth of Massachusetts plumbing code 248-CMR shall
be adhered to. A licensed plumber shall be used for this installation.
= The water softener requires a minimum water flow of 3 gallons per minute at the inlet. Maximum allowable inlet
w
ater pressure is 125 psi. If daytime pressure is over 80 psi, nighttime pressure may exceed the maximum. Use
a pressure reducing valve if necessary (Adding a pressure reducing valve may reduce the flow). If your home is
equipped with a back flow preventer, an expansion tank must be installed in accordance with local codes and laws.
=
The water softener works on 24V DC electrical power, supplied by a direct plug-in power supply (included). Be
sure to use the included power supply and plug it into a nominal 120V, 60 Hz household outlet that is in a dry
location only, grounded and properly protected by an overcurrent device such as a circuit breaker or fuse.
= Do not use this system to treat water that is microbiologically unsafe or of unknown quality without adequate dis-
infection upstream or downstream of the system.
European Directive 2002/96/EC requires all electrical and electronic equipment to be disposed of accord-
ing to Waste Electrical and Electronic Equipment (WEEE) requirements. This directive or similar laws are
in place nationally and can vary from region to region. Please refer to your state and local laws for prop-
er disposal of this equipment.
In the state of California: You must turn the Salt Efficiency Feature setting to ON. This may initiate
more frequent recharges. However, it will operate at 4,000 grains per pound of salt or higher. To turn
on the Salt Efficiency Feature, follow the instructions in the “Salt Efficiency” section of this manual.
Do not return the water softener to store.
