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.
