Product Water Flow And Product Water Quality - Sea Recovery Aqua Mini 170 Owner's Manual

System remains in operation when the operating pressure is above 950 PSI.
High Pressure Switch has drifted from factory setting.
• Operate System and pressurize to 950 psi. Adjust High Pressure switch to "open" at 950 PSI.
• Replace switch if necessary.

Product Water Flow and Product Water Quality

The system is operating at 850 psi and is not producing specified product water flow
• Feed Water salinity is greater than 35,000 PPM: Higher salinity Feed Water Requires higher Pressure to make
rated flow. Refer to Salinity Effects chart in this manual to identify expected pressure for Higher Salinity Feed
Waters. Do not exceed 900 psi operating pressure.
• System Feed Water temperature is lower than 77º Fahrenheit / 25º degrees Celsius: Lower temperature
feed water requires higher operating pressure to make rated flow. Refer to Temperature Effects chart in this
manual to identify expected pressure for lower temperature Feed Waters. Do not exceed 900 psi operating
pressure.
• NEW System Initial Commissioning: RO Membrane Element may have dried out between the time of installation
and the time of commissioning. Contact the factory if this time period is uncertain. If this may be the situation,
then operate system pressurized for 48 hours continuous to saturate and hydrate the R.O. Membrane Element.
Only do this if it is known that the system was shipped months prior to installation and commissioning was
performed months after installation, or if it is known that the R.O. Membrane Element has dried out.
• RO Membrane Element has been in use for a period of time and is fouled from use: If RO membrane element
has been stored improperly without proper flushing and/or storage solution or if it has simply slowly degraded
over time and use, then the Membrane may be fouled and cleaning may restore performance. If not, membrane
should be replaced.
• Membrane has chemical fouling: If RO membrane element has been performing normally and the drop in
production was sudden over one or two times of use it may be chemically fouled by petroleum or other pollutants.
• Membrane has dried out: If it is known that the R.O. Membrane Element has dried out operate system pressurized
for 48 hours continuous to saturate and hydrate the R.O. Membrane Element.
• R.O. Membrane Element has been exposed to temperatures in excess of 140 F / 60 C: Replace R.O.
Membrane Element.
• There may be a restriction in the product water line: Ensure that any valve in the product water line is fully
open. Note: It is preferred and recommended that there are no valves in the Product Water Line. Ensure that any
valve in the product water line is tight, a loose or easily turning valve handle will move and reposition itself due
to the movement and pounding of the boat.
System produces more than rated product water flow when operating from full seawater salinity of 35,000 ppm or higher
and the operating pressure is 400 PSI or lower and the Product Water Quality Lamp is illuminated "red"
1. A mechanical failure exists in the R.O. Membrane and/or High Pressure Vessel.
2. Cracked or broken RO Membrane Element product water tube which is caused by a blockage in the Product
Water Line during operation
3. Cracked End Plug in the High Pressure Vessel allowing seawater to mix with Product Water which is caused
by over tightening of tapered pipe fittings into the End Plug
4. Damaged or worn Product Water O-ring in the High Pressure Vessel End Plug
5. Lamination failure within the R.O. Membrane Element which is caused by a blockage in the Product Water Line
and/or air entrapment in the High Pressure Vessel is normally associated with mounting the High Pressure
Vessels vertically rather than horizontally.
ERROR ID 1: System produces expected rated product water flow with normal operating pressure after compensating
for Feed Water Salinity and Temperature and the Product Water salinity is above 100ppm for more than 10 consecutive
seconds
1. It is helpful to use a portable TDS meter to determine if the problem is with the R.O. Membrane Element or with
the Salinity Probe and Electronic monitoring system.
2. 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. This would usually result in higher than normal Product Water Flow.
