and tighten the nut on to the ¾” drain line tting. The nut is only designed for use with exible polytube. Use other nuts if attaching
different materials.
To access the drain line ow control remove the locking clip by pulling it straight out. Pull tting out and replace the locking clip so
that it is not misplaced. The drain line tting is pressed in and has an o-ring seal.
In the ¾” elbow, the white ow control retainer is pressed in and has an o-ring seal. The retainer can be removed by rotating and
pulling. The ow control can be removed by prying upward with a small blade at screwdriver in one of the slots on the side. The
drain line ow control and retainer can be chemically cleaned in dilute sodium bisulte or vinegar, or replaced. Do not use a wire
brush to clean the ow control or the washer. The washers are identied with three numbers, which correspond to the ow rate.
When reinstalling make sure the identifying number and the rounded inside diameter on the washer is visible when seated in the
retainer. The white ow control washer retainer can also be removed and cleaned. Push the retainer in rmly when reinstalling.
In the 1” straight tting, the retainer is the tting. Unscrew the nut to access the ow control. The drain line ow control and the
tting can be chemically cleaned or replaced. Do not use a wire brush to clean the ow control or the tting.
Do not use Vaseline, oils, or other unacceptable lubricants on o-rings. A silicone 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 sealants on threads. Use Teon tape on the threads of the drain line control tting when installing ¾” NPT or 1” straight
tting.
Installation Fitting Assemblies
The installation ttings connect to the control valve or the bypass valve using nuts that only require hand tightening. Hand tighten
nut connections between control valve and installation ttings, control valve and bypass valve, and bypass valve and installation
ttings allow for easy serviceability. Do not use a pipe wrench to tighten nuts on installation ttings. Hand tighten only.
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 installation ttings allows approximately 2 degrees off axis alignment to the
plumbing system. The installation ttings 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 tting package, connect the tting to the plumbing system rst 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, bypass valve or control valve. Solvent cements and primers should be used in accordance with the
manufacturer’s instructions.
Slip the nut onto the tting rst, then the split ring second and the o-ring last. Hand tighten the nut. If the tting is leaking tightening
the nut will not stop the leak. Remove the nut, remove the tting, and check for damage or misalignment of the o-ring.
Do not use pipe dope or other sealant on threads. Use Teon tape on threaded inlet, outlet and drain ttings. Teon 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 silicone 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 ttings, control valve and bypass valve, and bypass valve and installation ttings 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. Teon tape is not necessary on the caps because of o-ring seals.
Do not use Vaseline, oils, or other unacceptable lubricants on o-rings. A silicone lubricant may be used on black o-rings.
