INSTALLATION STEPS, continued
"
If making a soldered copper installation,
do all
sweat soldering before connecting pipes to the
softener fittings.
Torch heat will damage plastic
parts.
"
When turning threaded pipe fittings onto plastic
fittings, use care not to cross--thread.
"
Use pipe joint compound on all external pipe
threads.
"
Support inlet and outlet plumbing in some man-
ner (use pipe hangers) to keep the weight off of the
valve fittings.
5.
INSTALL GROUNDING CLAMP (IF NEEDED):
"
To maintain electrical ground continuity in the
house cold water piping, install the included ground
clamp as shown. Be sure the pipes are clean under
the clamps, to assure good contact.

CONNECT AND RUN THE
VALVE
DRAIN
HOSE:
"
Take a length of 3/8” inside diameter hose and
attach to the valve drain fitting.
"
Locate the other end of the hose at a suitable
drain point...floor drain, sump, laundry tub, etc.
Check and comply with local codes.
IMPORTANT: If a longer length of hose is needed,
buy and use high quality, thick--wall hose that will
not easily kink or collapse.
The water softener will
not work if water cannot exit this hose during regen-
erations.
"
Tie or wire the hose in place at the drain point.
Water pressure will cause it to whip during the back-
wash and fast rinse cycles of regeneration. Also pro-
vide an air gap of at least 1--1/2” between the end of
the hose and the drain point. An air gap prevents
possible siphoning of sewer water, into the softener,
if the sewer should back up.
"
If raising the drain hose overhead is required to
get to the drain point,
do not raise higher than 8’
above the floor
. Elevating the hose may cause a
back--pressure that could reduce brine draw during
regenerations.

To adapt a copper drain tube to the softener, buy a compression fit-

your local hardware store.
