Basic Installation Guidelines

  • Unit Assembly: Unit comes in two pieces, with float detached from motor unit for simplified shipping and storage. Minimal assembly is required and all hardware is provided, two 1/2in or 13mm sockets or wrenches will be needed.
  • PCC Installation: Qualified electrician will need to be on-site to install power control center (PCC is standard for all domestic/60Hz applications.)
  • Power Cable:  Power cable should be buried or trenched in conduit per local codes, and run at least 3ft or 1m out into the pond/basin.
  • Anchor/Mooring Unit in Water: Float unit into the water and either anchor or moor it in to place with nylon rope. For ponds that experience fluctuating water levels we recommend that you moor the unit into its location. Mooring the unit can often be done from the shoreline, while a boat is typically required when anchoring.
