    2. Start-up and Shut-down 2. 1. Start-up (1) Before starting the initial operation after installation, observe the following check items and, if anything abnormal is found, take necessary corrective action in accordance with this Manual. Are the pump and the suction pipe filled up with pumping liquid ? Is the driver's rotating direction correct ? (Pump rotates clockwise viewing from the driver's side) No abnormal in the direct coupling ? No abnormal load to the pump by piping ?

    (a) Apply oil coating in small quantity to O-ring ( 4120. 4 ). (b) Pay attention to the coiling direction of spring ( 4770 ). Viewing from the suction side, the right- hand coiled spring is for the suction side use and the left hand coiled one for the discharge side use.
  • Page 13 all the suction line valves are kept fully opened. In addition, inspect the suction pipe to check for poor fluid flow or great flow resistance. Clean well the strainer if provided. 5. Reverse rotational direction. Interchange the wiring connection to the motor terminal. Should the pump rotate reversely, check the packing sleeve and retighten it as necessary.
