START UP PROCEDURE After the arrangements regarding location, the pressure vase adequacy to local Technical Regulations and Legislations and the installation of the electrical network and the compressed air network are done (customer s responsibility), perform the following start up procedure: 1. Completely open pressure regulators to relieve the tank of any pressure. 2. Flip both control box switches ON and check if the rotation direction is anti-clockwise, viewed from fan. 3. Let the compressor run for about ten (10) minutes to allow a homogeneous lubrication of the moving parts. 4. Totally close the pressure regulator, so that the compressor can fill up the tank. The compressor will automatically turn off when the pressure gauge shows maximum pressure around 115 psig. 5. Open the pressure regulator to release the compressed air from the tank, to decrease its internal pressure. The compressor will automatically restart when the pressure gauge shows pressure around 85 psig. 6. Close the pressure regulator and unplug the equipment. 7. Verify if ASME safety valve is working. 8. Open drain petcock to exhaust the tank s condensed water and close it right after. a. WARNING: The tank should not be drained if the pressure is greater than 10 psig. 9. Open the pressure regulator to completely exhaust the tank, then close it. Your EAGLE Compressor is ready to operate. Connect it to the air distribution network and start the electric motor. When the compressor reaches maximum pressure, open discharge valve so that the air can flow into the 7
distribution network. Check if there is any leakage along the tubing, by using water and soap lather. In case there is any, eliminate it before proceeding. NOTE: This initial start-up procedure must be repeated each time maintenance occurs or when the compressor is moved to another location. 9. PREVENTATIVE MAINTENANCE In order to guarantee the compressor s perfect operation and to extend its life, please follow these recommendations below: 1. Monthly a. Check the operation of the pressure switch, by performing the start-up procedure b. Drain the condensed water from the tank, through drain petcock (The tank s pressure must not be greater than 10 psig) c. Check for abnormal noise or vibration.
