DRAINING THE TANK
WARNING: The tank contains high pressure air. Keep the outlet
of drain away from face and other body parts. Use safety glasses
when draining because debris can be kicked up into face. Use ear
protection because air flow noise is loud when draining.
NOTE: All compressed air systems generate condensate that
accumulates in any drain point (e.g. tanks, filter, aftercoolers, dryers).
This condensate contains lubricating oil and/or substances which
may be regulated and must be disposed of in accordance with local,
state, and federal laws and regulations.
1. Ensure that the ON/OFF switch is in the OFF position.
2. Move the compressor into an inclined position so that the drain
valve(s) are at the lowest point This will assist in removing
moisture, dirt, etc. from the tanks.
3. Place a suitable container under the drain to catch discharge.
