Do not attempt troubleshooting and/or subsequent correction or repair if you are not familiar with or are not proficient
in the above fields of expertise.
USE CAUTION WHEN TROUBLESHOOTING. DO NOT PERFORM MAINTENANCE UNLESS:
1. The system Feed Water Sea Cock Valve [2] is closed.
2. The system main electrical disconnect switch is switched "OFF", LOCKED, and TAGGED
3. The "EXPLODED PARTS VIEWS" of the this manual is available.
Caution: ELECTRICAL SHOCK HAZARD. A Volt / Ohm Meter will be necessary. The following procedures
expose the technician to High Voltage and electrical shock hazard. Only attempt this if you are a qualified
electrician and only if surrounding conditions are safe.
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 High
Pressure Pump [11] and Electric Motor [10] since they are subject to increased vibration.
2. Ensure that Sea Strainer [3] and Plankton Filter [5], if either are installed, are clean and do not restrict flow.
3. Check the level of the High Pressure Pump [11] crankcase oil. The minimum oil level is the center of the sight
glass, located at the side of the High Pressure Pump; the maximum oil level is at the top of the sight glass
window. Use only SRC High Pressure Pump oil. DO NOT USE MOTOR OR OTHER HYDRAULIC OIL.
4. Clean any salt water or salt deposits from the system with a wet rag.
5. Check for fluid leaks; either oil from the High Pressure Pump or water from anywhere in the system.
6. Check all tubing and high-pressure hoses for wear and friction against abrasive surfaces. The hoses should
not contact heated or abrasive surfaces.
7. Check Inlet Pressure to the High Pressure Pump. If pressure is below 10 psi after 5 minutes of operation,
replace Pre-Filter element.
Operator Maintenance Intervals
The frequency of required maintenance is dependent on the regularity of usage, the condition of the intake water
(the location of use), the length of time the system is exposed to water, the total running time and, in some cases,
the manner in which the system is installed or operated. Because of these factors, it is virtually impossible to
comprise an exact timetable for required maintenance. The following maintenance timetable is an estimate of the
time intervals at which maintenance may be required on the various systems components. This is based upon
factual data compiled from Sea Recovery installations around the world. However, this schedule must be adjusted
to each individual system depending upon the variables listed.
