Installation
7. COLD WATER PIPE GROUNDING
The house cold water pipe (metal only) is often used
as a ground for the house electrical system. The 3-
valve bypass type of installation, shown in Figure 7,
will maintain ground continuity. If you use the plastic
bypass, continuity is broken. To restore the ground,
do either step
7a
or
7b
following.
a
. Use the ground clamp kit (included) to make a
jumper across the inlet and outlet copper tubes (See
Figure 9).
b
. Install a #4 copper wire across the removed sec-
tion of main water pipe, securely clamping at both
ends (See Figure 10) – parts not included.
8. INSTALL VALVE DRAIN HOSE
NOTE:
See valve drain options on Page 5.
a
. Connect a length of 1/2" I.D. hose (check codes) to
the valve drain elbow, on the controller. Use a hose
clamp to hold the hose in place. Route the hose out
through the notch in the back of the top cover.
b
. Avoid drain hose runs longer that 30 feet. Make
the valve drain line as short and direct as possible.
c
. Run the hose to the floor drain, and as typically
shown in Figure 3, tie or wire the end to a brick or
other heavy object. This will prevent “whipping” dur-
ing recharges. Be sure to provide a 1-1/2" minimum
air gap, to prevent possible sewer water backup (See
“Air Gap Requirements” section).
