INSTALL GROUNDING CLAMP BETWEEN
THE SOFTENER IN AND OUT PIPES
The house cold water pipe (iron or copper) is often
used to ground all electrical outlets in the home.
Outlets are grounded to protect you from shock when
you touch any electric appliance plugged into the out-
let. If you installed the single bypass valve, the cold
water pipe ground is broken. See Fig. 20 and 21.
IMPORTANT: Be sure the cold water pipe has
direct metal to metal contact all the way to the
ground. Plastic, rubber or other electrically insulat-
ing parts such as hoses, fittings, washers or gas-
kets can break the direct metal to metal contact.
Also check the water meter (city water) or the well
pump. Install #4 copper jumper wires, clamped
tightly on both ends, across insulated parts. See
Fig. 21.
To restore the ground, take the ground clamp kit that is
in the parts bag. Install across the inlet and outlet cop-
per tubes. See Fig. 20. Be sure good contact is made
between the pipe and the clamps.
ELECTRICAL POWER OUTLET FOR
YOUR SOFTENER
The softener works on 24 volt, 60 Hz electric power.
The included transformer changes standard 120 volt
AC house power to 24 volts. You must plug the trans-
former into a grounded, 120 volt outlet only. Be sure
the outlet is always “live” so someone cannot turn it off
by mistake. See Fig. 22.
Note: The included transformer is made for inside use
only. Be sure the electrical outlet you plug the trans-
former into is inside, to protect from weather.
PLUG IN THE TRANSFORMER
Plug the transformer into the electrical outlet.
