Check electrical conditions of insulation on power cable and all phases of motor windings. 3. Check for any loose or faulty electrical connections at splice box or control, conditions of pump cable. 4. Test control voltage, supply transformer. 5. Test seal fail module. 6. Test Mini-CAS and submeg relays. 7. Check conditions of control wiring. 8. Check control contacts. 9. Check voltage supply on line side of control panel; pump off. 10. Check voltage on load side of control panel; pump on. 11. Check amperage draw of pump motor. 12. Check upper shaft seals, condition of stator housing and listen for bearing noise. 13. Check thermals and leak sensors, if so required. 14. Check lower shaft seals; change oil, if necessary. 15. Check impeller for wear; re-torque, if necessary. 16. Check wear rings. 17. Test mix flush valve. 18. Check discharge connection for leaks. 19. Check operation of check valve. 20. Check operation of gate valve. 21. Clean and test level sensors. 22. Check alarm functions, if required. 23. Check generator transfer, if required. 24. Reset control to automatic operation. 25. Provide complete report on inspection of each pump and control.
