= 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 your house water pressure is over the maximum, install a pressure reducing valve in
the water supply pipe to the system (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.

*
Intermittent flow rate does not represent the maxi-
mum service flow rate used for detemining the con-
ditioner's rated capacity and efficiency. Continuous
operation at flow rates greater than the service flow
rate may affect capacity and efficiency performance.
**
Typical residential chlorine concentration is 0.5 to 1.0
ppm.
Variable Salt Dose: The salt dose is selected by
the electronic controls at regeneration time based
on the amount needed.
