INLET/OUTLET PLUMBING
:
Be sure to install Bypass Valve onto main control valve before
beginning plumbing. Make provisions to bypass outside hydrant and cold hard water lines at this time.
Install an inlet shutoff valve and plumb to the unit’s bypass valve inlet located at the right rear as you
face the unit. There are a variety of installation fittings available. They are listed under Installation Fitting
Assemblies, page 17. When assembling the installation fitting package (inlet and outlet), connect the
fitting to the plumbing system first and then attach the nut, split ring and “O” Ring. Heat from soldering
or solvent cements may damage the nut, split ring or “O” Ring. Solder joints should be cool and solvent
cements should be set before installing the nut, split ring and “O” Ring. Avoid getting solder flux,
primer, and solvent cement on any part of the “O” Rings, split rings, bypass valve or control valve. If the
building’s electrical system is grounded to the plumbing, install a copper grounding strap from the inlet
to the outlet pipe. Plumbing must be done in accordance with all applicable local codes.

DRAIN LINE
:
First, be sure that the drain can handle the backwash rate of the system. Solder joints
near the drain must be done prior to connecting the drain line flow control fitting. Leave at least 6”
between the drain line flow control fitting and solder joints. Failure to do this could cause interior
damage to the flow control. Install a 1/2” I.D. flexible plastic tube to the Drain Line Assembly or discard
the tubing nut and use the 3/4” NPT fitting for rigid pipe (recommended). Where the drain line is
elevated but empties into a drain below the level of the control valve, form a 7” loop at the discharge
end of the line so that the bottom of the loop is level with the drain connection on the control valve. This
will provide an adequate anti-siphon trap. Where the drain empties into an overhead sewer line, a
sink-type trap must be used. Run drain tube to its discharge point in accordance with plumbing codes.
Pay special attention to codes for air gaps and anti-siphon devices.

BRINE TANK CONNECTION
:
Install the 3/8” O.D. polyethylene tube from the Refill Elbow to
the Brine Valve in the brine tank.
8.
OVERFLOW LINE CONNECTION:
An overflow drain line is recommended where a brine overflow could damage furnishings or the
building structure. Your softener is equipped with a brine tank safety float which greatly reduces the
chance of an accidental brine overflow. In the event of a malfunction, however, an overflow line
connection will direct the “overflow” to the drain instead of spilling on the floor where it could cause
considerable damage. This fitting is an elbow on the side of the brine tank. Attach a length of 1/2”
I.D. tubing to fitting and run to drain. Do not elevate overflow line higher than 3” below bottom of
overflow fitting. Do not “tie” this tube into the drain line of the control valve. Overflow line must be a
direct, separate line from overflow fitting to drain, sewer, or tub. Allow an air gap as per the drain line
instructions.
CAUTION: Never insert a drain line into a drain,
sewer line, or trap. Always allow an air gap
between the drain line and the wastewater to
prevent the possibility of sewage being back-
siphoned into the conditioner.
Drain Line
Air Gap
2 pipe diameters

To Wastewater
Waste connections or drain outlets shall be designed and
constructed to provide for connection to the sanitary waste
system through an air gap of 2 pipe diameters or 25 mm
(1 in), whichever is larger.
