Water Line Connection

EQUIPMENT INSTALLATION
When the water conditioning system is installed outdoors, several items
must be considered.
• Moisture — The valve and 700 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.
If it is necessary to locate the conditioner in direct sunlight, a
protective outdoor cover (P/N 1267811) over the valve and controller is
necessary.
• 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. A protective cover (P/N 1267811) should assist with
high temperature applications.
• Insects — The controller and valve have been designed to keep all but
the smallest insects out of the critical areas. Any holes in the top plate
can be covered with a metal foil duct work tape. The top cover should
be installed securely in place.
• Wind — The Logix cover is designed to withstand a 30 mph
(48 Kph) wind when properly installed on the valve.
A bypass valve system should be installed on all water conditioning
systems. Bypass valves isolate the conditioner from the water system and
allow unconditioned water to be used. Service or routine maintenance
procedures may also require that the system is bypassed. Figures 5, 6,
and 7 show the three common bypass methods.
