Attachment Nut
Purge Open/Close
The manual vent at the top of the
Vent/Purge assembly uses a directional
discharge cap. Turn the white cap to aim
the pressure discharge.
Vent/Purge Assembly incorporates a
built in purge valve. The valve is opened
by loosening the lower nut. To close the
valve, tighten the lower nut.
The Attachment Nut should not be
adjusted as this will remove the valve
from the assembly.
When tightening the compression nut,
hold the base firmly with a thin profile
box wrench. Do not let the base nut
tighten or loosen while adjusting the
compression fit.
Make sure to tighten the compression nut to 20
in-pounds of torque. If a torque wrench is
unavailable, tighten until snug and then one
additional 1/4” turn.
(Note: The compression sleeve is “directional”.
It is barbed on the inside to help lock the PEX in
place. Slide the sleeve onto the PEX so the
groove on the outside of the sleeve is closest to
the insert fitting - see diagram above).
Circuit Isolation Cap
Make sure o-ring seal is in
place to ensure a proper seal.
Gaskets must be installed.
Thread sealants or Teflon
are not
required.
