INSTALLATION FITTINg ASSEMBLIES
Installation fittings connect to the control valve or
the bypass valve using nuts that only require hand
tightening. Hand tight nut connections between
control valve and installation fittings, control valve and
bypass valve, and bypass valve and installation fittings
allow for ease serviceability. Do not use a pipe wrench
to tighten nuts on installation fittings. Hand tighten
only.
Split ring retainer design holds the nut on and allows
load to be spread over the entire nut surface area,
reducing the chance for leakage. 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
cements on any part of the o-rings or split rings, bypass
valve or control valve. Solvent cements and primers
should be used in accordance with the manufacturer’s
instructions.
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 connection 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.
Do not use Vaseline, oils or other unacceptable
lubricants on o-rings. A silicon lubricant may be used
on black o-rings.
ByPASS VALVE - CSM MODELS ONLy
The bypass valve easily connects to the control valve
body using nuts that only require hand tightening.
Hand tighten nut connections between control valve
and fittings, control valve and bypass valve, and
bypass valve and installation fittings allow for easy
serviceability. The split ring retainer design holds the
nut on and allows load to be spread over the entire
nut surface area, reducing the chance for leakage.
The split ring design, incorporated into the bypass,
allows approximately 2 degrees off axis alignment
to the plumbing system. The bypass is designed to
accommodate minor plumbing misalignments but is
not designed to support the weight of a system or the
plumbing.
Avoid getting primer and solvent cements on any
part of the o-rings or split rings, bypass valve or
control valve. Do not use pipe dope or other sealant
on threads. Teflon tape is not necessary on the caps
because of o-ring seals.
Do not use Vaseline, oil or other unacceptable
lubricants on o-rings. A silicon lubricant may be used
on black o-rings.
A. gENERAL
1. Shut off all water at main supply valve.
2. Shut off the fuel supply to water heater.
3. Open faucets (hot and cold) nearest pump or water
meter to relieve pressure and drain system.
4. Move softener into the installation position.
Loosely attach all fittings to measure for bypass
valve assembly (if used), or manual bypass valve.
5. Level the unit. Place shims under cabinet or brine
tank as needed. (Do Not use metal shims.)
6. Cut the cold water supply line as required.
7. Install the bypass valve assembly if used.
B. PLANNINg INSTALLATION
1. All installation procedures must conform to local
plumbing, electrical and sanitation codes and
ordinances.
2. It is recommended that outside faucets for lawn
service be on the hard water line, ahead of the
softener, to conserve softened water, save salt and
prevent lawn damage.
3. If this isn’t practical, use the convenient integral
bypass valve assembly.
CAUTION: The inlet water temperature MUST NOT
exceed 110° F.
4. Do not locate softener where ambient temperature
drops below 40° F.
5. Allow space around the softener for ease of
servicing.
6. The softener drain lines must never be solidly
connected to the sewer line. (Always provide an
air gap at the END of the drain line). Valve drain
