1. ATD 3443 VACUUM PUMP 3 CFM SINGLE STAGE As a specialized enterprise in making vacuum pumps we are always devoting ourselves to satisfying users need of high qualified products We adopt the latest design and technique to make sure that our products use less energy produce less noise and last long but also are the best design for protecting the environment and emitting less pollution Our excellent design and manufacturing will bring you more convenience 1 Pump Use ATD vacuum pumps are designed to obtain vacuum by pumping gas from sealed containers They are suitable for use with R12 R22 and R134a air conditioning systems as well as medical appliances printing machinery and vacuum packing They can be continuously used at 23 F 5 C to 140 F 60 C 2 Features Oil Anti flow back Design The gas inlet is specially designed to prevent the oil from flowing back preventing the container being pumped as well as the hoses from becoming contaminated Environmental Design The tank has separating devices at the exhaust port to prevent oil spraying and to reduce pollution Aluminum Alloy Casing The ATD vacuum pump is manufactured with an aluminum alloy casing Because aluminum has good heat dissipation qualities it will help to keep the pump running more efficiently for a longer period of time Overall Design The electric components and the pump are designed to make the product compact and lighter Easy to start Faster to pu2. F 60 C Don t use vacuum pump as a compression pump Pump cannot be operated without oil The operating voltage is between 110V to 115V 60Hz You must use a grounded outlet When unplugging the pump pull the plug Don t unplug unit by pulling on the wire Keep electrical cord free from all shop equipment and do not let pump hang by power cord Don t use damaged plug or outlet Don t plug or pull out the plug with wet hands Don t plug unit in unplug unit or use switch if there are any flammable or explosive gases present Always Unplug unit before disassembling 6 Installation When in use the pump should be horizontal and should be positioned where it is dry ventilated and free of dust and other contaminants In order to ensure proper air flow you must maintain a clearance around the pump of at least 10 cm 4 inches To permanently mount the vacuum pump remove the rubber pads from the bottom of the base and use the existing threaded holes to mount unit Mount with ST4 2 screws When permanently mounting this pump be sure to maintain proper clearances around the unit especially at the air intake in the end of the vane shell If a special electromagnetic valve is needed it can be installed on the gas inlet 7 Troubleshooting Problem Possible Cause Correction Low Degree 1 Lack of oil 1 Add oil to above the oil level line of Vacuum 2 Oil is not clea
