4. COMPLETE INLET AND OUTLET
PLUMBING
Pipe fittings must be 3/4” minimum.
Use:
=
Copper pipe
=
Threaded pipe
=
PEX (Crosslinked Polyethylene) pipe
=
CPVC plastic pipe
=
Other pipe approved for use with potable water
IMPORTANT:
Do not solder with plumbing attached to
installation adaptors and single bypass
valve. Soldering heat will damage the
adaptors and valve.Measure, cut, and
loosely assemble pipe and fittings from
the main water pipe to the inlet and out-
let ports of the water softener valve. Be
sure to keep fittings fully together, and
pipes squared and straight.
Be sure hard water supply pipe goes to the water sof-
tener valve inlet side.
NOTE:
Inlet and outlet are marked on the water sof-
tener valve. Trace the water flow direction to
be sure hard water is to inlet.
IMPORTANT:
Be sure to fit, align and support all
plumbing to prevent putting stress on
the water softener valve inlet and outlet.
Stress from misaligned or unsupported
plumbing may cause damage to the
valve.
Complete the inlet and outlet plumbing for the type of
pipe you will be using.
5. COLD WATER PIPE GROUNDING
CAUTION:
The house cold water pipe (metal only) is
often used as a ground for the house elec-
trical system, The 3-valve bypass type of
installation, shown in Figure 8, will maintain
ground continuity. If you use a plastic
bypass valve at the unit, continuity is bro-
ken. To restore the ground, do the follow-
ing:
a. Install the included metal ground clamp across the
removed section of main water pipe, securely tight-
ening the hardware at the center (See Figure 11).
NOTE:
Check local plumbing and electrical codes for
proper installation of grounding. The installa-
tion must conform to them. In Massachusetts,
plumbing codes of Massachusetts shall be
conformed to. Consult with your licensed
plumber.

6. INSTALL VALVE DRAIN HOSE
a
. Measure, cut to needed length and connect the 3/8"
inside diameter drain line (provided with some mod-
els) to the water softener valve drain fitting. Use a
hose clamp to hold the hose in place.
Installation Instructions
NOTE:
Avoid drain hose
runs longer than 30
feet. Avoid elevat-
ing the hose more
than 8 feet above
the floor. Make the
valve drain line as
short and direct as
possible.
NOTE:
If codes require a
rigid drain line see
Figure 13.
b
. Route the drain hose or
copper tubing to the
floor drain. Secure
drain hose. This will
prevent “whipping'' dur-
ing regenerations. See
“Air Gap Requirements"
section.

CONNECTING A RIGID VALVE DRAIN TUBE:
To adapt a copper drain tube to the softener, cut the
barbed end from the drain fitting, as shown. Obtain a
compression fitting (1/4” female pipe thread x 1/2” O.D.
tube) and needed tubing from your local hardware store.
