STEP BY STEP GUIDES TO INSTALL
:
4F. GROUNDING. CONNECT TO ELECTRICAL POWER
1. INSTALL GROUNDING WIRE BETWEEN THE FIL­
TER IN AND OUT PIPES
The house cold water pipe (iron or copper) is often used
to ground all electric outlets in the home. Outlets are
grounded to protect you from shock when you touch any
electric appliance plugged into the outlet. If you didn’t
install a three valve bypass (Figure 13), the cold water
pipe ground is broken.
To restore the ground, install the ground clamp to the in­
let and outlet pipes. Be sure the pipes are clean under
the clamps and wire for good contact,
IMPORTANT:
Be sure the cold water pipe has direct metal to metal con­
tact all the way to the ground. Plastic, rubber or other
electrically insulating parts such as hoses, fittings, wash­
ers or gaskets can break the direct metal to metal con­
tact, Also check the water meter (city water) or the well
pump. Install a #4 copper jumper wire, clamped tightly
on both ends, across insulated parts (Figure 15),
2. ELECTRIC POWER OUTLET FOR YOUR FILTER
The filter works on 24 volt, 60 Hz electric power. The in­
cluded transformer changes standard 120 volt AC house
power to 24 volts. You must plug the transformer into a
grounded, 120 volt outlet only. Be sure the outlet is al­
ways “live” so someone cannot turn it off by mistake,
NOTE:
The included transformer is made for inside use only. Be
sure the electrical outlet you plug the transformer into is
inside, to protect from weather (see page 7),
