Maintenance
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.
Commercial Prefilter Element Replacement:
To clean or replace the Commercial Prefilter
Element:
a) Unscrew the lid locking ring counter clockwise.
b) Remove and discard the used Commercial
Prefilter Pleated Cartridge Element from
the housing.
c) Thoroughly clean the inside of the bowl.
The High Pressure Pump is manufactured to
very tight tolerance spacing between moving
parts. Any debris entering the Pump will
cause extensive and expensive damage to
the internal parts. The Sea Recovery Prefilter
will stop any debris and protect the High
Pressure Pump. Use caution when changing
filter elements and do not allow any debris
from the prefilter element to enter the outlet
port of it’s housing.
d) Inspect the O-Ring attached to the lid.
Replace if damaged or if the lid leaks water.
e) Wipe the O-Ring with a damp cloth.
f) Sparingly lubricate the O-Ring with
O-Ring lubricant.
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.
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.
