INSTALLING GROUND:
To maintain an electrical ground in metal plumbing
of a home’s cold water piping (such as a copper plumbing system), install a
ground clamp or jumper wiring.
NOTE:
If replacing an existing softener, also replace the ground clamps/wire.
If removing a softener, replace the piping with the same type of piping as the
original to assure plumbing integrity and grounding.
8.
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” rigid 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. Run drain tube to its
discharge point in accordance with plumbing codes. Pay special attention to codes for air gaps and anti-siphon devices.
NOTE:
Drain line nut will not be supplied for units having a backwash rate greater than 7 gpm.
9.
BRINE TANK CONNECTION:
Install the 3/8” O.D. polyethylene tube from the Refill Elbow to the Brine Valve in the
brine tank.
10.
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.
