Pre-filter [6] Element Replacement
The Prefilter Pleated Cartridge Element may be cleaned with water spray once or twice. After cleaning the expected
life will be reduced in half. Attempts to clean the element more than twice will result in a very short life and will
damage the element rendering it useless. Change the element after the first or second cleaning. Clean or replace
the element when plugged to the extent that the Low Pressure Gauge at the control panel reads 10 to 6 psi. At
slightly below 6 PSI, the Low Pressure Switch shuts the system off.
Caution: Do not use third party prefilter elements; use only Sea Recovery Prefilter Elements. Third party
prefilter elements on the market do not properly fit, the seams fall apart, they will allow by-pass, and will allow
the R.O. Membrane Element to foul prematurely. Use of third party prefilter elements will void any and all
Sea Recovery warranty to the High Pressure Pump and the R.O. Membrane Element.
Important: Do not use “string wound” or “fiber” prefilter elements. These types of elements are designed
for the Photographic Film Developing industry. When used in sea water, they will plug up rapidly in 1/10th or
less the time causing frequent shut down of the system and very frequent changing which will also lead to
very high cost of maintenance. Use of String Wound or Fiber type elements will only lead to user frustration
and very high maintenance costs. Use of third party prefilter elements will void any and all Sea Recovery
warranty to the High Pressure Pump and the R.O. Membrane Element.
To clean or replace the Prefilter Element:
1. Unscrew the bowl counter clockwise.
2. Remove the Prefilter Pleated Cartridge Element from the bowl.
3. Remove the O-Ring from the top of the bowl. The O-Ring is fragile, so handle it with care.
4. Replace the Prefilter Pleated Cartridge Element with a new Sea Recovery element.
5. Wipe the O-Ring with a damp cloth.
6. Lubricate the O-Ring lightly using a sparingly amount of O-Ring lubricant.
7. Place the O-Ring back onto the bowl.
8. Insert the cleaned or new Sea Recovery Prefilter Pleated Cartridge Element into the bowl.
9. Screw the bowl on clockwise.
10. Hand snug to seal the O-Ring; do not use a wrench or other tool to tighten; do not over tighten. Over tightening
may damage the threads in the bowl or housing and cause removal to be difficult.
Low Pressure Gauge [7]
If the pressure gauge fails to register the orifice may be corroded with debris. Use a thin wire or small diameter
(1/64th” / 0.4 mm) drill bit to dislodge any debris trapped within the pressure port orifice. If clearing the orifice does
not bring the gauge to normal operation, then replace the gauge.
Brine Discharge Thru Hull Fitting [1]
Non Sea Recovery component. Keep the Brine Discharge Thru Hull Fitting free and clear of debris and corrosion.
