Location Selection
Location of a water treatment system is important. The
following conditions are required:
• Level platform or floor.
• Ambient temperatures over 34°F (1°C) and below 120°F
(49°C).
• Water pressure below 125 psi (8.61 bar) and above
20 psi (1.4 bar).
• In Canada, the water pressure must be below 100 psi
(6.89 bar).
• Constant electrical supply to operate the controller.
• Total minimum pipe run to water heater of ten feet (three
meters) to prevent backup of hot water into system.
• Local drain or tub for discharge as close as possible.
• Water line connections with shutoff or bypass valves.
• Must meet any local and state codes for site of
installation.
• Valve is designed for minor plumbing misalignments. Do
not support weight of system on the plumbing.
• Be sure all soldered pipes are fully cooled before
attaching plastic valve to the plumbing.
• Room to access equipment for maintenance and adding
salt to tank.

Outdoor Locations
It is recommended that the equipment be installed indoors.
When the water conditioning system must be installed
outdoors, several items must be considered.
• Moisture — The valve and controller are rated for NEMA 3
locations. Falling water should not affect performance.
The system is not designed to withstand extreme humidity
or water spray from below. Examples are: constant heavy
mist, near corrosive environment, upwards spray from
sprinkler.
• Direct Sunlight — The materials used will fade or discolor
over time in direct sunlight. The integrity of the materials
will not degrade to cause system failures.
• Temperature — Extreme hot or cold temperatures may
cause damage to the valve or controller.
Freezing temperatures will freeze the water in the valve.
This will cause physical damage to the internal parts as
well as the plumbing.
• Insects — The controller and valve have been designed to
keep all but the smallest insects out of the critical areas.
Things You Need to Know
• When the controller is first plugged in, it may display
an Err 3, this means that the controller is rotating the
camshaft to the home position.
• The preset default time of recharge is 2:00 AM.
• Make sure control power source is plugged in. The
transformer should be connected to a non-switched
power source.
• Test your water. Take a 4-5 oz sample of your water to
someone who can test for hardness. This information will
be used to setup the control.
