Seakeeper 2 Installation Manual (90488-3); S/N 2-203-0400 to 2-232-1563
Connecting Seawater to Heat Exchanger
Refer to Figure 2 for typical seawater plumbing arrangement.
- Connect seawater pump to Seakeeper dedicated through-hull fitting. A strainer and seacock valve should generally be installed between the seawater inlet and the pump.
- Connect seawater from installer supplied pump to lower 3/4 in. (19 mm) hose barb on heat exchanger. Use the same practices as other below waterline seawater plumbing.
- Connect seawater discharge to overboard drain. Use the same practices as other below waterline seawater plumbing.
- Required flow rate is 2 GPM (7.6 LPM) minimum and 6 GPM (22.7 LPM) maximum.
- In addition to initial operation at dock, new Seakeeper installations should be checked for minimum 2 GPM (7.6 LPM) flow while vessel is at speed and when backing down.
- If no other method of confirming flow is available, discharge line may be temporarily diverted to a bucket. Flow is calculated from time to fill a known volume.
- Flowrates in excess of 6 GPM (22.7 LPM) could affect heat exchanger life.
- Inspect raw water plumbing after sea trial for any signs of leakage.
