MAINTENANCE & REPAIR
Weekly Quick Check : The following steps ensure that potential problems are resolved preventing major repairs:
1. Inspect all fasteners for tightness including brackets, screws, nuts, and bolts. Pay special attention to
the Feed Water Pump [6] and its Electric Motor since they are subject to vibration.
2. Ensure that Sea Strainer [4] & Plankton Filter [7], if either are installed, are clean and do not restrict
flow.
3. Clean any salt water or salt deposits from the system with fresh water.
4. Check for fluid leaks; water from anywhere in the system.
5. Check all tubing and high-pressure hoses for wear and abrasion. The hoses should not contact heated or
abrasive surfaces.
Individual Component Maintenance & Repair
1. Inlet Thru Hull Fitting [1]: Non Sea Recovery component. Keep the Inlet Thru Hull Fitting free and clear of
debris and marine growth. If the Inlet Thru Hull Fitting is clogged, this results in a low feed pressure
condition, which causes the System to shut off. A clogged inlet thru hull fitting will also cause cavitation
damage to the Feed Pump [6].
2. Inlet Sea Cock Valve [2]: Non Sea Recovery component. The packing gland and connections of the Inlet Sea
Cock Valve must be tight and must properly seal. Clean the valve cavity of debris or replace the seal and seat,
or the entire valve, as required. This section is under a vacuum condition while operating the System. Loose
fittings or a worn seal will allow air to enter the Sea Recovery System causing continual shut down due to
subsequent low feed water pressure.
3. Sea Strainer [4]: Keep the mesh screen free and clear of debris. When the mesh screen is clogged, it results in a
low-pressure condition causing system shut off. A clogged Sea Strainer also causes cavitation damage to the
Feed Pump [6]. This section is under a vacuum condition while operating the System. If the Sea Strainer’s
bowl is loose or if the O-ring seal is worn or not properly seated air will enter the System causing continual shut
down due to subsequent low feed water pressure.
To clean the Sea Strainer:
a. Remove the bowl by turning it counter-clockwise.
b. Remove the Mesh Screen from the bowl.
c. Clean the Mesh Screen or replace it with a new one.
d. Remove the flat sealing gasket from the bowl and take care to not damage it.
e. Wipe the sealing gasket with a damp cloth. Lubricate it sparingly with petroleum free "O" ring
lubricant.
f. Place the seal back onto the bowl. Seat the mesh screen back into the bowl.
g. Screw the lid on clockwise.
Hand-tighten only enough to seal water in and air out . Over tightening will
cause an air leak and or the bowl to crack at the threads.
4. Pressure Gauges [5, 12, 16, 18]: If a pressure gauge fails to register the orifice may be corroded with debris. Use
a thin wire or small diameter (1/64th” / 0.4 mm) drill bit to dislodge any debris trapped within the pressure port
orifice. If clearing the orifice does not bring the gauge to normal operation then replace the gauge.
5. Feed Water Pump[6]: The Feed Water Pump is a precision fitted vane pump that relies on a very tight tolerance
in order to maintain flow and pressure. This pump is not field repairable. Should the pump develop a seal leak
or fail to maintain specified flow or pressure return it to Sea Recovery for repair or replacement. Remove the
Pump from the Motor, Bell Housing, and Flex Coupler and return only the Feed Water Pump head. Contact
