Caution: Do not use third party prefilter elements; use only PARKER 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 Parker warranty to the High-Pressure Pump and the RO Membrane Element.
The Prefilter Pleated Cartridge Element may be cleaned with water spray once or twice. After cleaning the
expected life will be reduced by 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.
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 RO Membrane Element.
