USER MANUAL
DUAL 400C ONBOARD AIR SYSTEM
2.0 GALLON AIR TANK & PLUMBING (CONT’D)
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 legs 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.
IMPORTANT:
- Tank is rated for 150 PSI maximum working pressure.
- Tank is NOT to be used as a breathing device.
- 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.
- Bleed pressure from tank before servicing or adding attachments.
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 5-20 PSI using drain cock.
- Drain 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.
SAFETY VALVE: 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 to vent pressure from the
tank before servicing.
