INSTALLATION
INLET/OUTLET PLUMBING: Connect to a supply line downstream of outdoor spigots. 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. 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
˚" I.D. flexible plastic tube to the
Drain Line Assembly or discard the tubing nut and use the ∫" NPT fitting for rigid pipe. If the backwash rate is greater than
7
gpm, use a ∫" drain line. W
here the drain line is elevated but empties into a drain below the level of the control valve, form a
7" (18 cm) 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 code. Pay special attention to
codes for air gaps and anti-siphon devices.
IMPORTANT:
Never insert a drain line directly 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.
BRINE TANK CONNECTION: Install a
3/8
" O.D. polyethylene tube from the Refill Elbow to the Brine Valve in the brine tank.
OVERFLOW LINE CONNECTION:
AN OVERFLOW DRAIN LINE IS RECOMMENDED WHERE A BRINE OVERFLOW COULD DAMAGE FURNISH- INGS
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 should be on the side of the cabinet or the brine
tank.
To connect overflow fitting, locate hole in side of brine tank. Insert overflow fitting into tank and tighten with plastic thumb
nut and
gasket from the inside. Attach a length of ˚" (1.3 cm) I.D. tubing (not supplied) to fitting and run to drain. Do not
elevate overflow line higher than 3" (7.6 cm) 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.
IMPORTANT:
Never insert a drain line directly 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.
