Page 4: Oil Filling
Oil level should be at the 3/4 position on the oil sight glass. Non-detergent oil should be used. Airtech recommends either ATO-1000 for normal duty operation or ATO2000 for severe duty operation. ATO oil is a high quality vacuum oil that will provide longer running time between oil changes, better lubrication at high operating temperatures and prolongs the life of the exhaust filter elements. -
Page 5: Gas Ballast
To stop the pump, turn off the power. A built in anti-suck back valve will prevent oil from the oil reservoir being sucked back into the cylinder after the pump is shutdown. Do not utilize the anti-suck back valve as a check valve. Consult Airtech Inc. for proper check valves. 2.3 Gas Ballast L-Series pumps are equipped with a gas ballast. -
Page 6: Inline (Inlet) Filter
Check inline (inlet) filter on a weekly basis. The filter cartridge should be cleaned or replaced when dirty. Consult Airtech Inc. for replacement element information. Caution: Depending on the mounting position of the filter, be careful not to allow accumulated foreign material to fall in the pump suction inlet when removing the filter cartridge. -
