  2. Install discharge pipe sizes equal to or greater than diameter of pump nozzles, and connect to sanitary drainage piping.
  3. Install swing check valve and gate or ball valve on each sewage pump discharge. Include spring-loaded or weighted-lever check valves for piping NPS2-1/2 and larger.
  4. Install electrical connections for power, controls, and devices.
  5. Electrical power and control components, wiring, and connections are specified in Division26 Sections.
  6. Ground equipment.
  7. Tighten electrical connectors and terminals according to manufacturer's published torque-tightening values. If manufacturer's torque values are not indicated, use those specified in UL486A and UL486B.

3.6ADJUSTING

  1. Pump Controls: Set pump controls for automatic start, stop, and alarm operation as required for system application.

3.7COMMISSIONING

  1. Final Checks before Starting: Perform the following preventive maintenance operations:
  2. Lubricate bearings.
  3. Disconnect couplings and check motors for proper direction of rotation.
  4. Verify that each pump is free to rotate by hand. Do not operate pump if it is bound or drags, until cause of trouble is determined and corrected.
  5. Verify that pump controls are correct for required application.
  6. Starting procedure for pumps with shutoff power not exceeding safe motor power is as follows:
  7. Start motors.
  8. Open discharge valves slowly.
  9. Check general mechanical operation of pumps and motors.
  10. Check alarm annunciation at Building DDC automation system.
