    INSTALLATION UNPACKING AND INSTALLATION UNPACKING EQUIPMENT Check the contents and all wrapping when unpacking your equipment. Inspect all parts for damage that may have occurred during shipping. Report any damage to the carrier. INITIAL LUBRICATION Pumps equipped with grease lubricated power frame bearings are lubricated at the factory prior to shipping and will require no additional lubrication until after the pump is put into service.
  • Page 6 INSTALLATION LOCATION The pump unit should be located as near as possible to the liquid source and in a position where the suction piping can be short and direct with a minimum number of elbows and fittings. It should also be readily accessible for inspection, cleaning, and lubrication.
  • Page 7 INSTALLATION FLEXIBLE COUPLING ALIGNMENT There are two types of misalignment encountered with flexible couplings: angular misalignment and parallel misalignment. To check for angular misalignment and parallel misalignment, insert a taper gauge or feeler gauge at four places located 90° apart around the coupling as shown in figure three.
