“Section I” System Troubleshooting Guide
If the operating pressure of 850 psi produces a Product Flow Meter reading below normal this
indicates one or more of the following causes:
The system Feed Water is at a low temperature;
The salinity of the Feed Water is greater than 35,000 ppm (typical Sea Water);
The R.O. Membrane Element is fouled and requires cleaning;
The R.O. Membrane Element has dried out and requires replacement;
The R.O. Membrane Element has been subjected to chemical fouling and requires replacement;
The R.O. Membrane Element has been exposed to temperatures above 140
°
F and requires
replacement;
The R.O. Membrane Element has been subjected to pressures above 1000 PSI, has been
compacted and requires replacement.
Product Water Flow Meter registers substantial flow when the system operating pressure is below
420 PSI and the system is operating in full salinity seawater.
The R.O. Membrane Element has a cracked product water tube.
A cracked or broken product water tube is caused by a blockage in the Product Water line.
Ensure that there are no blockages, valves or kinks in this line.
The End Cap Product Water O-Ring is cut or worn.
A worn product water O-Ring allows Feed Water to enter into the Product Water.
After compensating for Temperature of the Feed Water, the Product Water Flow Meter registers
lower than normal flow when the system operating pressure is 850 PSI and the system is operating in
seawater.
Membrane Element is fouled or has been damaged and requires cleaning or replacement.
There is a restriction in the Product Water Line.
Temperature and Pressure correction has not been properly calculated. Refer to Appendix B.
High Pressure Gauge is defective and registering higher than the actual applied pressure.
