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.
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 G of
this manual.
B. 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.
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.
The Line Power had a temporary drop out or voltage fluctuation caused by other auxiliary
equipment pulling current exceeding the permissible load on the Power Source.
There is a loose wire from the Power Source to the System or within the System Electronic
Controller, which is intermittently opening the power to the System.
C. VACUUM / LOW PRESSURE GAUGE READINGS:
The System is equipped with one or more Low Pressure Gauges depending upon which Pre-filtration
equipment is installed. Always correlate each of these Low Pressure Gauges to determine which
Pre-filtration component is dirty and requires maintenance. The inlet pressure minus the outlet
pressure of any component is known as the differential pressure.
The pressure gauges used through the System contain a small orifice at the pressure port stem. This
orifice can become plugged up with debris or corrosion. If the gauge fails to register then clean the
pressure pick up orifice with a thin stiff wire or small drill bit. Use caution when inserting the
cleaning wire or drill bit into the orifice.
