Location Selection
Location of a water treatment system is important. The
following conditions are required:
• Level platform or floor.
• Room to access equipment for maintenance and adding
salt to tank.
• Ambient temperatures over 34°F (1°C) and below 120°F
(49°C).
• Water pressure below 125 psi (8.6 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 for discharge as close as possible.
• Water line connections with shutoff or bypass valves.
• Must meet any local, state and international codes for the
installation site.
• 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.
Outdoor Locations
It is recommended that the PRF1035CS system be installed
indoors. When the water conditioning system must be installed
outdoors, several items must be considered.
• Moisture — The valve and 706W 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.
High temperatures will affect the controller. The display
may become unreadable but the controller should
continue to function. When the temperature drops down
into normal operating limits the display will return to
normal.
• Insects — The controller and valve have been designed to
keep all but the smallest insects out of the critical areas.
The top cover should be installed securely in place.
