“CMP” & “C” Series Automatic Water Conditioners
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 the 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 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
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.
