2.0 Gallon Air Tank Installation

Your 2.0 Gallon air tank is shorter than most tanks on the market and has been
designed for use with vehicles without much room underneath. The tank comes with six
1/4” NPT port openings to allow installation in many configurations on your vehicle. To
insure safe and trouble-free use of your air tank, we strongly recommend that you
install the supplied drain cock and a safety pressure relief valve. (Use contents of
Package # 1 for this installation step).

IMPORTANT:

• Tank is rated for 150 PSI maximum working pressure.

• Tank is not to be used as a breathing device.

• Bleed pressure from tank before servicing or adding attachments.

• Use only attachments or tools rated for 150 PSI working pressure or less.

CAUTION! DO NOT PRESSURIZE YOUR TANK UNTIL YOU HAVE INSTALLED ALL NECESSARY
PORT FITTINGS AND ACCESSORIES.

• Apply sealant to threads of fittings prior to assembly and tighten each part with a
wrench.

• Do not over tighten if your port fittings are made from brass, since brass threads can
be stripped.

• Always release air from tank before servicing.

WARNING: FAILURE TO DRAIN TANK AND REMOVE CONDENSATION WILL CAUSE TANK TO
RUST PREMATURELY.

• To remove accumulated condensation inside the tank, bleed pressure from tank until
pressure is approximately 5 PSI to 20 PSI using drain cock

• Drain water from tank by opening the drain cock drain valve and close after draining
tank.

• If drain cock valve is plugged, release all air pressure from tank, remove drain valve
and clean, then reinstall.

IMPORTANT: Please observe air tank’s Date of Manufacture (stamped on tank leg).
Replace air tank 2 to 5 years from date air tank was first used, or use the date of
manufacture as reference. Adhering to air tank draining guidelines will prolong the
life of your air tank.

PLEASE NOTE: RUSTED TANKS CAN FAIL CAUSING EXPLOSIONS OR FATAL INJURIES.

Discard tank immediately if tank is rusted internally. When using a safety pressure
relief valve, point the safety pressure relief valve away from your body when
releasing air. Use the pull ring on the safety relief valve; open the relief valve to
vent any pressure inside the tank before servicing tank.

Tank Fittings:

Install the supplied fittings for the air tank in areas where they are most appropriate
for your installation using thread sealant or Teflon tape. (Not all installations will
be plumbed exactly as shown in schematic.) Make sure that the safety valve is installed
in the top most position on the tank, and that the drain cock is installed in the lowest
position on the tank if the tank is to be installed in any other position than upright on
the tank’s mounting legs. Be sure that all fittings are accessible later in the
installation process since you will have to plumb air lines to each fitting as needed to
utilize the air tank.

Mounting the Tank:

We have included 6 pieces of rubber bushings in your tank mounting hardware. You
have the option of using two layers of rubber bushings on one of your tank lags to
slightly tilt tank toward the drain cock port to improve drainage properties. Use the
provided longer bolts, and corresponding washers, lock washers and nuts to mount the
tank to a suitable chassis or other place on your vehicle.

Dual 325C Air Compressor Installation

Your Onboard Air System comes complete with two very fast, 33% Duty Cycle
compressors. Please follow these installation instructions to enjoy the best use of
your onboard air system. (Use compressors and the contents of Package # 2 for this
installation step)

CAUTION - To reduce risk of electrical shock or electrocution:

• Do not disassemble the compressor. Do not attempt repairs or modifications. Refer to
qualified service agencies for all service and repairs.

• Do not use this product in an area where it can fall or be pulled into water or
liquids.

• Do not reach for this product if it has fallen into liquid.

• Use this compressor with 12-volt DC systems only.

• This product should never be left unattended during use.

Guidelines for Selecting Mounting Location:

The selection of proper mounting locations for your air compressor will help ensure a
long and trouble free compressor service life. Please pay close attention to the
following:

• Select a flat & secure location where the compressors can be mounted.

• To maximize air compressor performance, locate compressor as close to the battery
as possible so that length of positive lead wire required is at a minimum.

• Choose mounting locations that are as cool as possible and away from heat sources.

• This compressor is moisture & dust resistant, but NOT WATERPROOF or DUSTPROOF. Do
not mount compressor in locations where the unit is likely to come in contact with
water or excessive dirt.
