WARNING: By-pass of debris through
the third party element will extensively
damage the High Pressure Pump.
By-pass of debris through the third
party element will also prematurely foul
the R.O. membrane element. 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
type 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.
DO NOT ACCEPT THIRD PARTY PREFILTER ELEMENTS
FROM ANY MARINE DEALER. USE ONLY SEA RECOVERY
SUPPLIED PREFILTER ELEMENTS. The resulting failure
of the system to remain in operation, and or damage to
the Sea Recovery System caused by Third Party Prefilter
Elements is attributed to improper maintenance and
operation, is the liability of the operator and owner, and is
not covered by the Sea Recovery warranty.
