Bypass 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 3 and 4 show the
two common bypass methods.

If this unit includes a bypass valve (Figure 3), it can be used by
itself or with a manual bypass (Figure 4).

Drain Line Connection

NOTE: Standard commercial practices are expressed here.
Local codes may require changes to the following
suggestions. Check with local authorities before
installing a system.
1. The unit should be above and not more than 20 feet
(6.1 m) from the drain. Use an appropriate adapter fitting
to connect plastic tubing to the drain line connection of the
control valve.
2. The drain line may be elevated up to 6 feet (1.8 m) providing
the run does not exceed 15 feet (4.6 m) and water pressure
at the softener is not less than 40 psi (2.76 bar). Elevation
can increase by 2 feet (61 cm) for each additional 10 psi (.69
bar) of water pressure at the drain connector.

3. Where the drain line is elevated but empties into a drain
below the level of the control valve, form a 7-inch (18-cm)
loop at the far end of the line so that the bottom of the loop
is level with the drain line connection. This will provide
an adequate siphon trap. Where the drain empties into an
overhead sewer line, a sink-type trap must be used.
Secure the end of the drain line to prevent it from moving.
INCORRECT
Construct air gap as shown or purchase air
gap device as used with clothes washers.
Figure 5 Drain Line Connection
NOTE: Waste connections or drain outlets should be designed
and constructed to provide for connection to the
sanitary waste system through an air gap of two pipe
diameters or one inch (22 mm) whichever is larger.
Never insert drain line directly into a drain,
WARNING:
sewer line, or trap (Figure 5 Drain Line
Connection). Always allow an air gap between
the drain line and the wastewater to prevent
the possibility of sewage being back-siphoned
into the softener.

General Installation Notes

1. Place the softener tanks where you want to install the unit.
NOTE: Be sure the tanks are level and on a firm base.
2. During cold weather it is recommended that the installer
warm the valve to room temperature before operating.
3. Perform all plumbing according to local plumbing codes.
— Use a 1/2" minimum pipe size for the drain.
4. Lubricate the distributor O-ring seal and tank O-ring seal.
Place the main control valve on one tank and the tank
adapter on the second tank.
NOTE: If required, solder copper tubing for tank
interconnection before assembling on the main
control valve and tank adapter. Maintain a
minimum of 1" distance between tanks on final
assembly.
5. Solder joints near the drain must be done before connecting
the Drain Line Flow Control fitting (DLFC).Leave at least
6" (152 mm) between the DLFC and solder joints when
soldering pipes that are connected on the DLFC. Failure to
do this could cause interior damage to DLFC.
6. Use only plumber tape on the drain fitting.
7. Be sure the floor under the salt storage tank is clean and
level.
8. Place approximately 1" (25 mm) of water above the grid
plate of the salt storage tank before filling with salt. Add
salt to brine tank so that salt level is above the brine well
air check.
9. Make all electrical connections according to codes. Plug the
valve into an approved power source.
10. Tank one has control valve and tank two has adapter.
11. Look on the right side of the control valve, it has indicators
showing which position the control valve is in during
Regeneration and which tank is In Service.
