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, pages 16-17. 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 barbed fitting and use 3/4" NPT fitting of 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 <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. 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.
