inlet of the unit when pressure is under 6 psi (0.35 BAR).
7 TROUBLESHOOTING
7.1 System Shuts Down During Operation
NUMBER ONE REPORTED PROBLEM IS “THE SYSTEM DOESN’T WORK!”
Detail and record everything happening with the system. Read Chapter 7 of the manual, see if some of the
problems listed and the solutions applies to the commissioned system.
Parker’s technical support team
can help you if there are any further questions.
NUMBER TWO REPORTED PROBLEM IS "System Shuts Down by Itself" with "ERROR ID 2" or "ERROR ID 3"
(High/Low Pressure Fault)
1.
To clear the alarm or “fault” Press Start/Stop Button
2.
While observing Low- and High-Pressure Gauges Start System:
a.
ERROR ID 2 : If the High-Pressure Sensor increases beyond 950 PSI and the unit
shuts down, Start the unit again and check the Brine Discharge Section as well as
the Product Line Section, make sure:
•
No kinks or blockages are in the Brine Discharge Line
•
No kinks or blockages are in the Product Water Line
b.
ERROR ID 3: If the Low-Pressure sensor decreases to near or below 6 PSI, check the
inlet line and associated components prior to the High-Pressure Pump Inlet:
•
Sea cock valve must be fully open.
•
Check for air suction leaks at all components and fittings prior to the Boost Pump
•
Check sea strainer screen and clean/clear debris. Check for any suction leaks.
•
Check the
prefilter Element clean manufacturing or installation debris.
•
Check the plankton Filter Element clean manufacturing or installation debris.
•
No kinks or blockages in the inlet line and check for air suction leaks.
•
Ensure that the boost Pump is operational and delivering flow and pressure.
•
Check Inlet Thru-Hull Fitting clean manufacturing or installation debris and check for
air suction leaks.
•
Check if there is any caulking compound in the thru hull opening, and that all
shipping covers and tape on the hull has been removed. Shipping cover or tape
below the hull in the water.
•
Check for a Plastic bag or other debris in the water below the hull in the water.

Please read this carefully: Debris may plug up the Prefilter Element causing the system to
shut down. After shutdown, that same debris may settle off of the prefilter element and
down into the prefilter housing bowl. Re-starting of the system may initially give normal
readings. However, after a short period of time, the debris will stir up and once again clog
the prefilter element causing the system to shut down due to low pressure.
