Pressure Abnormalities
• Vacuum/Pressure -30 - 0 - 60
• Low Pressure 0-300 PSI
• High Pressure 0-1500 PSI
• System shuts off due to Low Pressure
• System shuts off due to High Pressure
Low-Pressure Abnormalities
Debris may plug up the prefilter elements causing the system to shut down. After shut-down, that same
debris may loosen or settle off of the prefilter elements and down into the prefilter housing bowl.
Restarting the system may initially give normal pressure-gauge readings. However, after a short period
of time, 5 to 20 minutes, the debris will stir up, pack back onto the prefilter elements and, once again,
clog them causing the system to shut down due to low pressure. Therefore, if the system shuts down
after a few minutes of starting, restart the system and observe the pressure gauges during this time
interval to determine if clogged prefilter elements are the reason for shut-down.
Another cause may be a plastic bag or other debris attached to the thru-hull inlet fitting that, after
several minutes of operation, finds its way over the inlet thru-hull fitting, then drops away when the
system shuts down, only to reappear when the system is again restarted.
Air can also enter the suction portion of the feed line causing the Booster Pump to lose pressure and
flow. This can be difficult to detect and will only appear when the line is under a vacuum condition
caused by a blockage in the line prior to the air leak. Air may also enter the feed line through the inlet
thru-hull fitting from under the boat when the boat is underway.
High-Pressure Abnormalities
High-pressure abnormalities, excessive or higher than normal pressure at the RO Membrane Element
as registered on the High-Pressure Gauge, can be caused by low-temperature feed water, high-salinity
feed water, fouled RO Membrane Element, a blockage in the brine discharge line, and/or a blockage
in the product water line.
High-Pressure or Low-Pressure Abnormalities Due to Mismatch of Components
The Seafari Escape System is designed to recover as product water a fixed percentage of the feed
water. The system self-adjusts the operating pressure in order to maintain a constant and set product
water flow. Therefore, the system will never experience greater than or less than normal product water
flow, unless there is a failure or abnormality.
Three components must be properly matched in order to attain acceptable operating pressure limits
and resulting product water production limits. The ETD, the RO Membrane Element and the Booster
