The pressure differential readings across the
Prefilter indicate that the elements are filled with
debris blocking the feed water.
Solution : Replace the Prefilter Elements.
12) COMMERCIAL PRE-FILTER
The Commercial Prefilter housing contains a 5 micron
cartridge filter element that has 38 square feet of filtering
surface area. This over size cartridge provides extended
life that greatly reduces maintenance and prefilter
element replacement cost. As the cartridge filter element
becomes plugged up with debris pressure and flow drop
resulting is System shut down due to low pressure into
the High Pressure Pump. The cartridge filter element
may be cleaned once to gain approximately 50% of the
original life. After the first cleaning it must be discarded
and replaced with a new element.
WARNING! PREFILTER ELEMENT : Do
not use third party prefilter elements, use
only Sea Recovery prefilter elements.
Third party prefilter elements do not
properly fit and the seams fall apart.
They also allow by-pass resulting in
premature fouling of the R.O. membrane
element and extensive damage to the
High Pressure Pump. Damage to the Sea
Recovery System caused by the use of
third party, non Sea Recovery, Prefilter
Elements is the responsibility and liability
of the operator and not covered by the
Sea Recovery Warranty.
CAUTION ! Finger tighten the lid locking
ring onto the base. DO NOT over tighten.
DO NOT use any wrench or device to
tighten the lid locking ring. The lid is
O-ring sealed, two finger tightening is
adequate. Over tightening will stress the
threads on the base and the lid locking
ring causing them to crack.
Problems and Symptoms appearing and caused
by the Prefilter:
a)
The Feed Water Pressure into the Prefilter is higher
than normal, and the Feed Water Pressure into the
High Pressure Pump is lower than normal.

WARNING! PREFILTER ELEMENT
:
Do not use third party prefilter elements,
use only Sea Recovery prefilter elements.
Third party prefilter elements do not

PREFILTER ELEMENT CAUTION ! 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. This will cause frequent shut
downs of the system and very frequent
changing which will result in very high
cost of maintenance and user frustration.
CAUTION ! Hand tighten the bowl onto
the filter top housing. DO NOT over
tighten. DO NOT use any wrench or
device to tighten the bowl. It is O-ring
sealed, hand tightening is adequate. Over
tightening will stress the bowl and top
causing it to crack.
