Spring Start-Up

We've gathered some helpful information to help get units up and running for the 2022 season!

Spring Start-Up: Power Control Centers

Spring start-up is the perfect time to perform an evaluation/maintenance within the power control center (PCC).

  1. First step is tightening all wire connection points. Should the control center have an Eaton Contactor, you’ll need to confirm that the correct terminal connection port is being used and has tight connections. Ideally, this is done before you energize the control center. If you need further details see Technical Bulletin #124.
  2. If the control center has a digital timer make sure the program is set and that the backup battery has a charge. A blank timer face doesn’t mean that the timer has failed; it may need a quick reset! The reset button is located on the right hand side above the minute button. Pressing this button may restore operation!
  3. Remember to install fresh insect repellent to prevent any pesky infestations. Cattle tags with pesticides are a great way to deter bugs at a low-cost! When you’re ready to activate the control center, reference the Otterbine PCC Analysis Report. This report guides you through all the voltage amp draw measurements. Not only that but it will help record all the data! Another important step at this point in PCC start-up is testing the GFCI controls.
  4. The last step for PCC start-up is making sure you set the panel to the proper mode of operation: timer mode or manual mode. If you need a component refresher on power control centers prior to spring start up, simply venture to the Otterbine website and log on to the Distributor Dashboard. There you’ll be able to find our “Otterbine Service Center Learning Series”. Currently, there are three videos dedicated to PCCs!

Spring Start up: Otterbine Aerators

Let’s not forget about the aerators! Before putting the unit back into operation make sure you use our spring start-up list.

  • Physically inspect the Unit.
  • Clear Pump Chamber components of debris.
  • Clear Screen of debris.
  • Confirm ground points on the Power Unit.
  • Check continuity between the S/S Housing and Ground Pin on Bulkhead. This confirms that the ground clip is contacting the housing and ensures the unit is properly grounded.
  • Inspect Underwater Cable for cuts, cracks and/or breaks along the cable pigtail connection. Should the cable have a broken pigtail nut now’s the best time to replace it (if you need a refresher check out the Otterbine Video Learning Series).
  • Ensure the Cable Strain Relief is properly installed. We’ve also got a video covering this!
  • Clean old Dielectric Compound from Bulkhead Connector by brushing it from the cavity.
  • Apply fresh Dielectric Compound or Silicone Grease (P/N 48-0001) in the Bulkhead Connector. Otterbine now recommends applying the compound by brushing it into the bulkhead cavity nice and evenly. A small amount of compound goes a long way in this instance!
