Pressurizing the Housing

Before You Begin
Have the following on hand:
- A tank of dry nitrogen. Dry nitrogen is readily
available. To obtain supplies, check with a
medical or industrial gas provider. If the tank is
to be carried transported, a 40 cubic foot tank is
recommended.
WARNING!
care. Although nitrogen is an inert
gas, the tank is highly pressurized
and if the valve or regulator is
damaged the tank could be
dangerous.
- A regulator on the tank. Nitrogen tanks have a
standard 580 fitting. However, a regulator is
required.
- A hose with an air chuck to connect the
regulator to the housing's air intake valve.
The intake valve (also called a purge,
Schraeder, or dill valve) is similar to the intake
valve on a bicycle tire. To connect the regulator
to the purge valve on the housing, a hose is
needed with a ¼-inch barb on one end and an
air chuck on the other. The barb connects to the
regulator on the tank; the chuck connects to the
purge valve on the housing.
The American Dynamics product code for the
Nitrogen kit (Nitrogen Tank, Hose, and Regulator)
is RHONKIT.
