6. 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 24-25.
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.
7. 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). If the backwash rate is greater than 7 gpm, use a 3/4" drain line.
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. Piping
the drain line
overhead
<10 ft is
normally not a
problem. Be
sure adequate
pressure is
available (40-60
psi is recommended). Where the drain empties into an overhead sewer line, a sink-type trap must be used
with appropriate air gap (see drawing). Run drain tube to its discharge point in accordance with plumbing
codes. Pay special attention to codes for air gaps and anti-siphon devices.
8. BRINE TANK CONNECTION: Install the 3/8" O.D. polyethylene tube from the Refill Elbow to the Brine
Valve in the brine tank.
9. 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.
