FCI WATERMAKERS, INC. 109 Maintenance & Repair
PRE-FILTER ELEMENT REPLACEMENT
PRE-FILTER ELEMENT REPLACEMENT
The pre‑filter 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. At slightly below 5 PSI
the system will turn off and display a fault screen indicating low pressure.
CAUTION:
Do not use third party pre-filter elements; use only FCI
Watermakers pre-filter elements. Third party pre-filter 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 prematurely
foul the R.O. membrane element. Use of third party pre-filter elements will void
any and all FCI Watermakers warranty to the R.O. membrane element.
IMPORTANT:
Do not use “string wound” or “fiber” pre-filter 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 pre-filter elements will void
any and all FCI Watermakers warranty to the R.O. membrane element.
DO NOT ACCEPT THIRD PARTY PRE-FILTER ELEMENTS
FROM ANY MARINE DEALER. USE ONLY FCI
WATERMAKERS SUPPLIED PRE-FILTER ELEMENTS.
The resulting failure of the system to remain in operation, and or damage
to the FCI Watermakers system caused by third party pre-filter elements is
attributed to improper maintenance and operation, is the liability of the
operator and owner, and is not covered by the FCI Watermakers warranty.
