Troubleshooting
Error ID 1: High Salinity Fault
System produces expected product water flow with normal operating pressure after compensating for Feed Water
Salinity and Temperature; however, the Product Water salinity is above 100ppm for more than 10 consecutive
seconds.
1. We recommend using a portable TDS meter to determine if the problem is with the RO Membrane Element or
with the Salinity Probe and Electronic monitoring system.
2. A damaged or worn Product Water O-ring at one of the End Plugs within the High Pressure Vessel is allowing
Feed Water to mix with Product Water, which would typically result in higher than normal Product Water Flow.
However, a small nick in the O-ring may allow enough Feed Water to mix with the Product Water to cause the
condition without resulting in a noticeable increase in Product Water Flow.
3. A crack in one of the End Plugs within the High Pressure Vessel is allowing Feed Water to mix with Product
Water, which would typically result in higher than normal Product Water Flow. However, a small crack may
allow enough Feed Water to mix with the Product Water to cause the condition without resulting in a noticeable
increase in Product Water Flow.
4. RO Membrane Element is fouled due to normal use and requires cleaning.
5. Salinity Probe has debris on the probe causing the system to read poor water quality. Clean the Salinity Probe
with a toothbrush.
Error ID 2: High Pressure Fault
If the High Pressure Sensor increases beyond 950 PSI and the System shuts down, press the "Start/Stop" button.
A high pressure fault can be caused by:

Low Temperature Feed Water

High Salinity Feed Water

Fouled RO Membrane Element

Blockage in the Brine Discharge Line

Blockage in the Product Water Line
Error ID 3: Low Pressure Fault
A low pressure fault can occur when the following conditions occur:

The value at the Low Pressure Sensor is below 4 PSI for more than 20 seconds

The Low Pressure Sensor is disconnected or malfunctioning

The value at the High Pressure sensor is below 4 PSI for more than 20 seconds

The High Pressure Sensor is disconnected or malfunctioning
To troubleshoot, check for the following:

Cock Valve must be fully open

Air suction leaks at all components and fittings prior to the Feed Pump

Whether or not the Sea Strainer Mesh Screen is clean (no manufacturing or installation debris) and if air suction
leaks are present

Whether or not the Pre-Filter Element is clean (no manufacturing or installation debris)

Whether or not the Plankton Filter Element is clean (no manufacturing or installation debris)
