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.
High Pressure Causes
: This may be due to
pressurizing the System above 950 psi. The
High/Low Pressure Fault Lamp illuminates
immediately when the High Pressure Switch is
OPEN and the system shuts off immediately.
Solution
: Follow the Brine Discharge Line
and ensure that there is no kink or blockage
in this line. Ensure that any Valve in the Brine
Discharge Line is fully OPEN.
Follow the Product Water Line and ensure that
there is no kink or blockage in this line. Ensure
that any Valve in the Product Water Line is
fully OPEN.
Open the Back Pressure Regulator Valve fully.
Press the Fault Reset Switch then Start the
System. The High Pressure Gauge reading at
the control panel should be below 50 psi at
this time.
Adjust the Back Pressure Regulator as
explained in the Start Up Procedure in Section
6 of this manual.
2) System shuts down by itself and a fault lamp
is not illuminated:
If the system shut down but a Fault Lamp is not
illuminated, then the cause would be electrical.
Power loss caused the system to shut down
.
The Power Source Circuit Breaker feeding the
system has tripped and requires resetting, or
it is weak and not passing full voltage, or it is
rated too low for the full load amperage of the
system.
Solution
: Reset the Circuit Breaker and check
the circuit breaker to ensure that it passes full
voltage across all legs when the system is fully
pressurized.
Ensure that the Circuit Breaker is of the proper
amperage rating for the System.

7 TROUBLESHOOTING
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 9 of this manual.
1) System shuts down by itself and a fault lamp
is illuminated:
View the Touch Pad Fault Indication Lamps.
a) 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.
Solution : Press the Fault Reset Switch then
Start the System. Take note of the Low
Pressure Gauge reading at the control panel.
-
If the Low Pressure Gauge does not move
from zero this indicates that there is air
entering the System intake line.
Solution : Correct any air suction leaks.
- 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.
Solution

Clean the Sea Strainer Mesh Screen
•
Back Wash the Multi Media Filter
•
Clean the Plankton Mesh Screen
•
Change the Pre-filter Element(s)
