Outdoor Locations
When the water conditioning system is installed outdoors,
several items must be considered.
• Moisture – The valve and control 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
Figure 3 Remote Start/Multi-Tank Lockout Cable
below. Examples are: constant heavy mist, near
corrosive environment, or upwards spray from
sprinkler.
Caution: This unit is for dry location use only unless
used with a Listed Class 2 power supply suitable for
outdoor use.
Figure 4 Twin Sensor Cable
• 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, an outdoor cover (PN 1267811)?? over
the valve and control is necessary. Valve skirts
(PN 1267808)?? are available if further protection is
required.
• Temperature – Extreme hot or cold temperatures will

Note: Standard commercial practices are expressed
here. Local codes may require changes to the following
suggestions. Check with local authorities before installing
a water conditioning system.
The system should be above, and not more than 20 feet
(6.1 m) from a drain. Connect an appropriate fitting and
3/4-inch (1.9-cm) plastic tubing to the drain line

Brine Line Connection
It is recommended that separate brine lines be used for
each tank.
The regenerant line from the tank connects to the valve.
Make the connections and hand tighten. Be sure that the
regenerant line is secure and free from air leaks. Even a
small leak may casue the regenerant line to drain out, and
the conditioner will not draw regenerant from the tank.
This may also introduce air into the valve causing
problems with valve operation. Ensure that Teflon* tape
pipe sealant is applied to the 3/8-inch NPT regenerant line
connection (Figure9).

Note: Do not elevate the overflow line higher than

Do not tie into the drain line of the control unit. The
overflow line must be a direct, separate line from the
overflow fitting to the drain, sewer, or tub. Allow an air gap

Caution: Plumbing cannot be used for electrical
grounding when metal inlet and outlet piping is
connected to a non-metal valve.
Figure 11
Connect the inlet and outlet piping together using a
grounding strap or clamp to establish continuity.
Brine Tank
Normally one brine tank is needed for each media tank.
The use of block salt or rock salt is not recommended. If a
brine shelf is used, two brine tanks are required. This is due
to the increased time needed to produce a concentrated
brine solution when using a salt shelf. If rapid multiple
exhaustions and regenerations are anticipated, do not use
a salt shelf even if two brine tanks are used.
Electrical Connection
Caution: This valve and control are for dry location use
only unless used with a Listed Class 2 power supply
suitable for outdoor use.
The 764 Series control operates on a 12-volt alternating
current power supply. This requires use of the GE Water
Technologies supplied AC adapter. A variety of AC
adapters are available from your supplier for different
applications. They include:
