IMPORTANT PLEASE READ:
�Warranty of this product extends to manufacturing defects.
�The information, specifications and illustrations in this manual are based on the latest
information available at the time of printing. The manufacturer reserves the right to make
changes at any time without notice.
�This product should be installed by a plumbing professional on potable water systems only.
�This product must be installed in compliance with all local and state and municipal plumbing and
electrical codes. Permits may be required at the time of installation.
�If operating pressure exceeds 100 psi a pressure reducing valve must be installed. If operating
pressure drops below 30 psi a booster pump must be installed.
�Do not install the unit where temperatures may drop below 32°F or rise above 100°F.
�A prefilter should be used on installations in which free solids are present.
�A constant voltage of 120V/60Hz (unless otherwise specified) must be supplied to the controller
to maintain proper function.
�Union or flange fittings are recommended at the control valve's inlet, outlet, and drain
connections
�If distance of drain line is over a 10 ft. vertical or 25 ft. horizontal run, increase drain line one
pipe size over that provided on the control valve.
�Do not make a direct connection to the drain. Provide an air gap of at least four times the
diameter of the pipe to conform to sanitation codes and to permit observation of the flow.

Maximum salting is 15 pounds of salt per cubic foot of resin. This setting gives the longest time
between regenerations. It has an efficiency of 2,000 grains of hardness removed per pound of
salt. The Brine tank and Regeneration timer are setup for maximum salting at the factory.
Minimum salting is 6 pounds of salt per cubic foot of resin. It has an efficiency of 3,300 grains of
hardness removed per pound of salt.
Freeboard is the distance between the surface of the resin and the top side shell of the tank.
On continuous flow rates pressure loss does not exceed 15 psig.
On peak flow rates pressure loss does not exceed 25 psig.
Minimum operating pressure is 30 psi.
Maximum operating pressure is 100 psi.
Standard units are designed to soften unheated water in the range is 35-100F.
Power requirements are 120 Volt, 60 Hertz, Single Phase, 2 amps
