INSTALL GROUNDING CLAMPS AND WIRE (Recommended):
o
To maintain electrical ground continuity in the
house cold water piping, install the ground clamps
(not included) as shown. Be sure the pipes are clean,
under the clamps, to assure good contact.
NOTE: A 3-valve bypass system maintains ground
continuity.
5.
PLUMB IN AND OUT PIPES TO AND FROM SOFTENER:
CAUTION:
Observe all of the following cautions as you connect inlet and outlet
plumbing.
o
Turn off the house water supply valve and open faucets to relieve pressure
in the pipes.
o
BE SURE RAW,
HARD WATER
IS DIRECTED
TO
THE VALVE
INLET
PORT.
o
Be sure to use bypass valve(s).
o
If making a soldered copper installation, do all sweat soldering before
connecting pipes to the softener fittings.
Torch heat will damage plasticparts.
o
Put grounding clamps (see step 4) on copper tubes before soldering.
o
When turning threaded pipe fittings onto plastic fittings, use care not to cross-
thread.
o
Use pipe joint compound on all external pipe threads.
o
Support inlet and outlet plumbing in some manner (use pipe hangers) to keep the
weight off of the valve fittings.
6.
CONNECT AND RUN THE VALVE DRAIN HOSE: (figure 4)
o
Take a length of 3/8” or 7/16” inside diameter hose and attach to the valve
drain fitting. So water pressure does not blow the hose off, use a hose clamp
to secure in place.
o
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: 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 regenerations.
o
Tie or wire the hose in place at the drain point.
Water pressure will cause it to whip during the
backwash and fast rinse cycles of regeneration.
Also provide an air gap of at least 4 cm 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’’.
