Mount Components

Connect Seakeeper and Customer Supplied Cables

High Current 12 VDC Conductors (Seakeeper Supplied)
- Connect High Current DC Input cables (P/N: 20335 and 20336) to customer supplied 2 AWG B+ and B- conductors to allow for routing to 12 VDC power source.
- Connect High Current DC Input B+ conductor (red) through 100 A circuit breaker(customer-supplied) and a dedicated battery isolation switch (customer-supplied), directly to the battery positive terminal or bus bar.
- Connect High Current Input B- conductor (black) to battery negative terminal or DC negative bus bar.
  
  NOTE: If the 2 AWG high-current 12V power input conductors are shortened or lengthened, use heavy-duty eyelet (closed end) terminals such as Molex19221-0235.
Ground Cable (Customer Supplied)
- Install lugs on both ends of customer-supplied 4 AWG ground cable.
- Connect one end of Ground Cable to nearest vessel ground and other end to Seakeeper foundation.
- 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.
Low Current 12 VDC Power Input Cable (Seakeeper Supplied)
- Connect DC Input positive (red) cable (P/N: 20248) directly to a customer-supplied 15 A circuit breaker, then to the dedicated battery isolation switch
- Connect DC Input negative (black) cable (P/N: 20248) to the DC negative bus bar or battery negative terminal.
- Plug DC Input Cable connector end into the DT-Series connector labelled Low-Current 12 VDC in connector on the Seakeeper wire harness.

DC Seawater Pump Input Cable (Seakeeper Supplied)
- Connect Seawater Pump Input positive (red) cable (P/N: 30327) directly to a customer-supplied circuit breaker corresponding to the seawater pump overcurrent protection rating (max 15 A), then to the dedicated battery isolation switch.
- Connect Seawater Pump Input negative (black) cable (P/N: 30327) to the DC main negative bus bar or battery negative terminal.
DC Seawater Pump Output Cable (Seakeeper Supplied)
- Connect female end of DC Seawater Pump Output Cable (P/N 20334) to customer supplied 12 VDC, 15 A seawater pump.
- Plug male end connector of DC Seawater Pump Output Cable (P/N 20334) into mating connector on the Seakeeper wire harness

Connect seawater hoses / open sea cocks to heat exchanger and test seawater pump.
Verify 2 GPM (7.6 LPM) minimum and 6 GPM (22.7 LPM) maximum seawater flow through heat exchanger under all operating conditions of the boat. (The seawater pump output will operate for two minutes after the Seakeeper is turned on. During operation, the seawater pump output is turned on and off based on the temperature of the Seakeeper)
Verify coolant level in heat exchanger coolant reservoir.

Remove lifting bolts and install cover panels
Turn on 12 VDC 15 A circuit breaker
Turn on 12 VDC 100 A circuit breaker
Verify display works and no ALARMS are present
- If display does not work, turn off both circuit breakers immediately
- Check polarity of 12 VDC 15 A power per Section 2.2.5
Follow instructions in Installation Manual Section: Start Up Instructions, to turn on the Seakeeper
Verify seawater pump turns on when the Seakeeper is turned ON
Verify that no ALARMS are present
Follow instructions in Installation Manual Section: Start Up Instructions, to turn off the Seakeeper
DC power and seawater pump may be turned off after the Seakeeper is turned off by placing the Seakeeper in LOCK mode and turning the Seakeeper off
Seakeeper 2 takes 16+ hours to coast down to 0 RPM from full speed
