USER MANUAL
ULTRA-LIGHT DUTY ONBOARD AIR SYSTEM
1.0 GALLON AIR TANK & PLUMBING
Your 1.0 gallon air tank comes with four 1/4” NPT port openings. To insure safe & trouble-free use of your air
tank, install the drain cock and a safety pressure relief valve. (See Figure 1)
Tank Fittings:
Install supplied fittings for the air tank in areas where they are most appropriate for your installation using
thread sealant or Teflon tape. Make sure that the safety valve is installed in the top of the tank, and that the
drain cock is installed in the lowest position of the tank Be sure that all fittings are accessible since you may
have to plumb each fitting as needed to utilize the air tank properly.
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: Replace air tank 2 to 5 years from date air tank was first used.
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.
