  • Connect spliced Cable 2, B- conductor (black), to battery minus terminal or DC main negative bus bar.

Seawater Pump Connection: Cable 5 & 7

  • Connect Cable 7 positive (red) directly to a customer-supplied circuit breaker corresponding to the seawater pump current overprotection rating (max 15 A), then to the dedicated battery isolation switch.
  • Connect Cable 7 negative (black) to the DC main negative bus bar or battery minus terminal.
  • Connect Cable 5 receptacle end (pins) to Seakeeper 1 SW Pump 12 VDC Out and the plug end (sockets) to customer-supplied 12 VDC seawater pump cable Deutsch connector termination.

Ground Connection: Cable 6

  • Butt splice Cable 6 to customer-supplied ground wire, 4 AWG, with sufficient length to reach the vessel ground.
  •  Vessel grounding bus to comply with:
    • EM/IEC 60204-1 Clauses 6.3.3 and 8.2.3.
    • ABYC E-11 July 2018 Clauses 11.5.2 and 11.16.1.

Cooling Checklist

  • Purchase seawater pump for Seakeeper 1 to provide 2 – 4 GPM (7.6 – 15.2 LPM) with a max overcurrent protection rating of 15 A.
    • Optional seawater pump can be purchased through Seakeeper, P/N 30331.
  • Connect and route seawater inlet hoses from seacock valve to the seawater strainer, seawater pump, then Seakeeper 1 heat exchanger.
  • Connect and route seawater outlet hoses from Seakeeper 1 heat exchanger to the seawater overboard.
  • Test seawater pump.
    • Verify 2 GPM (7.6 LPM) minimum and 4 GPM (15.2 LPM) maximum seawater flow through heat exchanger under all operating conditions of the vessel.
  • Verify coolant level in heat exchanger coolant reservoir, fill if needed.
