I. SYSTEM TROUBLESHOOTING GUIDE
Some system problems have possible causes located in more than one subsystem, and are categorized here
according to the subsystem in which they are indicated or most likely to be located. Where two or more
possible causes are listed for a problem, it is advised that they be checked in the order listed. This
Troubleshooting Guide lists the abnormal symptom and its possible cause. In order to correct the problem or
repair the part, refer to the Maintenance and Repair Section K of this manual.
A. SYSTEM SHUTS DOWN BY ITSELF AND A FAULT LAMP IS ILLUMINATED:
View the Touch Pad Fault Indication Lamps.
If the High/Low Pressure Fault Lamp is Illuminated:
NOTE: This indicator may illuminate due to either a Low Pressure Fault or due to a High Pressure
Fault. The two causes are examined below.
LOW PRESSURE CAUSES: The High/Low Pressure Fault Lamp illuminates when the Low
Pressure Switch is OPEN and after 10 seconds of illumination the System shuts off.
Press the Fault Reset Switch then Start the System. Take note of the Low Pressure Gauge
reading at the control panel.
1. If the Low Pressure Gauge does not move from zero this indicates that there is air
entering the System intake line.
Correct any air suction leaks.
2. If the Low Pressure Gauge needle moves and registers below 6 psi or draws a vacuum
this indicates one or more dirty Pre-filtration components.
Open the Inlet Seacock Valve.
Clean the Sea Strainer Mesh Screen.
Back Wash the Multi Media Filter.
Clean the Plankton Mesh Screen
Change the Pre-filter Element(s).
Change the Oil/Water Separator Element.
Note: After the last shutdown and after the system has sat for some time, the debris
clogging the particular filter element becomes loose and settles to the bottom of the filter
bowl. There may be sufficient pressure at the Low Pressure Gauge immediately after
starting the system, but within 30 to 60 minutes the system shuts down again because debris
is stirred up and clogs the filter element.
