6/ TROUBLESHOOTING
During performance comparisons, feed water temperature, feed water salinity, and
system operating pressure must be taken into consideration and be compensated for.
After compensations, a 15% decline in productivity (GPH Flow) and/or a 15% increase
in salt passage indicate that the R.O. membrane element may require cleaning.
If production rate has dropped dramatically since the last time the system was used, this
may be due to drying out of the R.O. membrane element and/or fouling during storage.
If the system has not been used for several months and the production rate has dropped
dramatically since the last time used, try operating the system for 48 or more continuous
hours to saturate the product water channel within the R.O. membrane element.
If production rate drops dramatically from one day to another, this may be
due to chemical attack, which is not cleanable. Sewage chemicals or petroleum
products cause irreparable damage to the R.O. membrane element. Suspended
solids fouling resulting from silt, coral dust, iron (rust), river or inland
waterway debris, or other small solid matter may not be cleanable.

Table 3 on page 124.
If you experience drastic changes in performance,
take note of the following...
