PWSR Series Softeners 9
NOTICE
When assembling the installation fitting package, connect
the fitting to the plumbing system first and then attach the
nut, split ring and o-ring . Heat from soldering or solvent
cements may damage the nut, split ring, and o-ring . Make
sure solder joints are cool before assemble is started .
Split ring retainer design holds the nut on and allows load to be
spread over the entire nut surface area reducing the chance for leak-
age . The split ring design, incorporated into the installation fittings
allows approximately 2 degrees off axis alignment to the plumbing
system . The installation fittings are designed to accommodate minor
plumbing misalignments but are not designed to support the weight
of a system or the plumbing .
When assembling the installation-fitting package, connect the fitting
to the plumbing system first and then attach the nut, split ring and
o-ring . Heat from soldering or solvent cements may damage the nut,
split ring, or o-ring . Solder joints should be cool and solvent cements
should be set before installing the nut, split ring, and o-ring . Avoid
getting primer and solvent cement on any part of the o-rings, split
rings, and bypass valve or control valve . Solvent cements and prim-
ers should be used in accordance with the manufacturer’s instruc-
tions .
3/8" Quick Connect
Fitting
Slip the nut onto the fitting first, then the split ring second and the
o-ring last . Hand tighten the nut . If the fitting is leaking tightening the
nut will not stop the leak . Remove the nut, remove the fitting, and
check for damage or misalignment of the o-ring .
Do not use pipe dope or other sealant on threads . Teflon tape must
be used on the threads of the 1" NPT elbow and the 1/4" NPT con-
nection and on the threads for the drain line connection . Teflon tape
is not necessary on the nut connection or caps because of o-ring
seals .
Move Brine Tank Next to Softener and Connect Brine
Draw Line to Valve
1 . Connect the brine tank to the
water softener control valve
brine inlet port using the
factory supplied fittings and
tubing . Add enough water to
the brine tank so that water
covers the top of the air
check . DO NOT ADD SALT
AT THIS TIME .
2 . With brine tank next to the softener tank connect the brine draw
line to valve body . Connect to valve body 3/8" Quick Connect
fitting .
Control valves that use a regenerant, come equipped with a 3/8"
refill flow control assembly .
Complete the connection by installing the loose end of the tub-
ing to the brine valve in the salt tank .
Connect the Drain Line
1 . Plumb the drain line to an appropriate drain abiding by all local,
city, and state codes . Use a 3/4” drain line for backwash flow
rates of 7 gpm or for drain lines of 7 gpm and less that exceed
20’ in length . Use a 1” drain line for backwash flow rates of 10
gpm and 12 gpm .
2 . If the drain line is a 5/8" flexible poly tube, slide the nut onto the
poly tube, then place the poly tube insert into the end of the poly
tube and tighten the nut on to the 3/4" drain line fitting . The nut
is only designed for use with flexible poly tube . Use other nuts if
attaching different materials . Run line to a drain . Making sure you
have a 1 1/2" airgap . You may use a floor drain, standpipe or any
open type drain (see Fig . 7 on page 10) .
Do not use Vaseline, oils, or other unacceptable lubricants on
o-rings . A silicon lubricant may be used on the black o-ring .
Use a pliers or crescent wrench to tighten or unscrew the nut . Do
not use a pipe wrench to tighten or loosen nut . Do not use pipe
dope or other sealant on threads . Use Teflon tape on the threads of
the drain line control fitting when installing 3/4" NPT or 1" straight
fitting .
Move Water Softener Into Place
1 . Connect the cold water supply to the inlet of the water condition-
ing system . While constructing the supply line, install a master
supply valve (user supplied) in the supply line and close it .
2 . Connect the feed water line to the home to the outlet of the
system .
3 . Make sure floor is level .
Measure, cut, and install pipe and fit-
tings to the bypass valve (dry fit only to
make sure you have a proper fit) inlet
and outlet side . Be sure hard water is
supplied to the inlet side . Trace pipe
to be sure .
The installation fittings connect to the
control valve or the bypass valve using
nuts that only require hand tighten-
ing . Hand tighten nut connections
between control valve and installation
fittings,control valve and bypass valve,
and bypass valve and installation fit-
tings allow for easy serviceability . Do
not use a pipe wrench to tighten nuts
on installation fittings . Hand tighten
only .
