To install a purge kit

1. Attach the plumbing assembly to the purge gas source.
a. Install the regulator valve and either a 1/4-inch male fitting or a 3/8-inch female
fitting on the purge gas source. (Choose a valve and fittings that are appropriate for
the purge gas source.)
b. If you used a 1/4-inch male fitting, proceed to the next step.
If you used a 3/8-inch female fitting on the purge gas source, install the 3/8-inch to
1/4-inch reducing nipple that was included with your purge kit. Wrap the reducing
nipple with thread seal tape before you install it, and use an 11/16-inch open-ended
wrench to tighten the connection.
c. Wrap the reducing nipple or the 1/4-inch male fitting with thread seal tape, and then
install the pressure coupling. Use a 3/4-inch open-ended wrench to tighten the
connection.
