Installation

Nitrogen Unit Installation

This procedure can be used for both 1st or 2nd Generation units. The Input line connection is on the bottom of the tank on the 2nd Generation, on the side for 1st Generation as shown here.

The very first step is to locate where the unit is to be installed. DO NOT install this in the back room where the air compressor is located. High temperatures (100 deg +) will result in decreased output through the membranes. The ideal location is right out in the shop area against a wall, as you see here.

Here is an N2G17-FP unit after it arrives and with the large cardboard box removed.

Remove the lag bolts securing the N2 Unit to the pallet, and carefully move it to the shop floor, and discard the pallet.

A very important step

Once you have the unit positioned where you want it, drill and install 4 concrete anchors to hold it securely. Installing with rubber isolator pads is even better.

Note: If the unit is not sitting with all four legs touching the floor at the same time, you must shim where needed so no stress is placed on the receiver tank.

Depressurize your main air compressor line going to the shop.

Now install a "Tee" in your regular air compressor line, in most cases 1/2" NPT for installation of a Filter / Regulator.

We can supply the correct unit, but if you supply your own, it must be adjustable for at least 175 PSI, and contain a coasescing filter with an automatic drain to prevent water & oil buildup.

When an Input Hose is ordered from us, we supply all necessary fittings to make your installation easier. (Actual fittings may differ from the photo)

Now, connect the non-swivel end of the hose to the Input side of the N2 Unit.

Make sure you're taping all your threaded ends.

	Now connect the swivel end of the Input Hose to the output elbow of the Filter / Regulator

	Conduct Input Line Leak Test First, make sure the Input Valve is closed as in the picture to the left. Then, with the main compressor line pressurized, turn the Regulator Knob until the guage reads approximately 15 - 20 psi. Listen for air leaks, if there are none, proceed with the installation

Purge The Tank
Close the outlet valve Open the inlet valve, and turn the Regulator to full pressure. (150 - 175psi) Let the N2 Unit run until the tank guage reads about 45 - 50 psi. Close the inlet valve Open the output valve slowly and bleed most, but not all of the Nitrogen from the tank,then close the outlet valve again. Go to the next step below.

Install the Outlet hose - Method #1

There are two connection types you can choose from.

1. - Use the N238-30 30 ft Green Coilhose connected directly to the tank. ( shown here )

2. - Connect directly to an existing shop-wide Nitrogen-only 1/2" pipe. ( shown below )

Remember! Teflon tape your threads.

Install the Outlet hose - Method #2

We make two different Outlet hoses, 6 ft and 10 ft, both ends 1/2" NPT swivel.

As a precaution to shop personnel, you should paint or identify the Nitrogen-only pipe with Green pain or Green labels.

Another trick to use is to install a different style of quick disconnect on the Nitrogen-only line so personnel can only connect tire filling hoses only to the Nitrogen supply.

And here's the moment of truth!

The reason you purged the N2 Unit previously is to get rid of as much air inside the tank as possible, leaving only Nitrogen.

The results speak for themselves. The image to left is from an actual installation after purging and refilling.
It indicates there is only 1% Oxygen in the tank, which means a 99% Nitrogen purity level.

You're done!
