Installation Instructions
4. COLD WATER PIPE GROUNDING
CAUTION:
The house cold water pipe (metal only) is
often used as a ground for the house elec-
trical system, The 3-valve bypass type of
installation, shown in Figure 6, will maintain
ground continuity. If you use a plastic
bypass valve at the unit, continuity is bro-
ken. To restore the ground, do the follow-
ing:
a
. Install a #4 copper wire across the removed section
of main water pipe, securely clamping it at both
ends (See Figure 12) - parts not included.
NOTE:
Check local plumbing and electrical codes for
proper installation of grounding. The installa-
tion must conform to them. In Massachusetts,
plumbing codes of Massachusetts shall be
conformed to. Consult with your licensed
plumber.
5. INSTALL VALVE DRAIN HOSE
a
. Take a length of 5/8” inside diameter garden hose
and attach to the valve drain fitting (See Figure 7 on
page 7).
b
. Locate the other end of the hose at a suitable drain
point (floor drain, sump, laundry tub, etc.). Check
and comply with local codes. Refer to Figure 7 on
page 7 if codes require a rigid pipe drain run.
IMPORTANT:
Use high quality, thick wall hose that will
not easily kink or collapse. The filter will
not backwash properly if water cannot
exit this hose during recharges.
c
. 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 recharge. 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 filter, if
the sewer should back up.
d
. If raising the drain hose overhead is required to get
to the drain point, do not raise higher than 8 feet
above the floor. Elevating the hose may cause a
back pressure that could reduce backwash flow and
proper mineral bed cleaning.
6. FLUSH PIPES, CIRCULATE DISINFEC-
TANT, EXPEL AIR FROM FILTER, AND
TEST YOUR INSTALLATION FOR LEAKS
CAUTION:
To avoid water or air pressure damage to
filter inner parts, be sure to do the following
steps exactly as listed:
a
. Fully open two cold, filtered water faucets nearby
the filter.
b
. Place bypass valve(s) into “bypass” position. On a
single valve, slide the stem inward to BYPASS (See
Fig. 7 on page 7). On a 3 valve system, close the
inlet and outlet valves, and open the bypass valve
(See Fig. 6 on page 7).
c
. Fully open the house main water pipe shutoff valve.
Observe a steady flow from both opened faucets.
d
. Place bypass valve(s) into “service”, EXACTLY as
follows. KEEP FILTERED WATER FAUCETS OPEN.
=
Single Bypass Valve:
SLOWLY, pull the valve
stem outward to ”service” position, pausing sev-
eral times to allow the filter to pressurize slowly.
=
3 Valve Bypass:
Fully close the bypass valve
and open the outlet valve. SLOWLY, open the
inlet valve, pausing several times to allow the fil-
ter to pressurize slowly. The sanitizing bleach
also circulates through the filter.

3. COMPLETE PLUMBING TO AND FROM
THE FILTER
Using the “Typical Installation Illustrations” on page 7
as a guide, observe all of the following cautions while
you connect inlet and outlet plumbing:
=
Be sure incoming,
unfiltered water
is directed to
the valve
INLET
port.
=
Be sure to install bypass valve(s).
=
If making a soldered copper installation, do all
sweat soldering before connecting pipes to the filter
fittings. Torch heat will damage plastic parts.
=
Use pipe joint compound on all external pipe
threads.
=
When turning threaded pipe fittings onto plastic fit-
tings, use care not to cross-thread.
=
Support inlet and outlet plumbing in some manner
(use pipe hangers) to keep the weight off of the
valve fittings.
