The water softener requires a minimum water flow of 3 gallons per minute at the inlet. Maximum
allowable inlet water 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 24 volt--60 hz electrical power only, supplied by a direct plug--in
transformer (included). Be sure to use the included transformer and plug it into a nominal 120V, 60
cycle household outlet that is properly protected by an overcurrent device such as a circuit breaker or
fuse. If transformer is replaced, use only the authorized service, Class II, 24V 10VA transformer.
This system is not intended to be used for treating water that is microbiologically unsafe or of unknown
quality without adequate disinfection before or after the system.
European Directive 2002/96/EC requires all electrical and electronic equipment to be disposed of
