FCI WATERMAKERS, INC. 25 Pre-Installation
PRE-FILTER
The system comes with one 5 micron, 40‑sq. ft. pre‑filter. Connections
are 3/4” hose barb for the inlet and discharge line and 1/2” tubing
compression fitting for the fresh water flush connection.
The filter should be cleaned or replaced when the low‑pressure reading reaches 5
PSI or when the system shuts down on low pressure. The filter can be cleaned once
or twice before replacing. When cleaning the pre‑filter, do not scrub the pleats to
the point that the material begins to fray. If fraying occurs, replace element.
NOTE:
The pre-filter is your first line of defense protecting
the high-pressure pump and membrane. Keeping the filter in
good condition will help insure trouble-free operation.
WARNING: PRE-FILTER ELEMENT
Do not use third party
pre-filter elements, use only FCI pre-filter elements. Third party pre-filter
elements do not properly fit and the seams fall apart. They also allow
by-pass resulting in extensive and very costly damage to the high pressure
pump as well as premature fouling of the R.O. membrane element(s).
CAUTION: PRE-FILTER ELEMENT
Do not use “string wound” or “fiber”
pre-filter elements. String wound and fiber filter elements are designed for
the photographic film developing industry. When used in seawater, they will
plug up rapidly in 1/10th or less the time of a FCI supplied pre-filter cartridge
element. This will cause frequent shut downs of the system and very frequent
changing will result in very high cost of maintenance, and user frustration.
DESPITE BEING FRAMED, THESE SYSTEMS ARE DESIGNED FOR
VERSATILITY AND OPTIMIZED TO MEET CUSTOM DEMANDS.
For instance, the system shown to the left is a 3‑vessel system (the system can
be equipped with 1, 2 or 3 vessels). The frame was design to provide as much
versatility for installation as possible. If the depth is too great, the membranes can
be removed and remotely mounted on a bulkhead or overhead. (Special mounting
fittings required, please consult your dealer or FCI Watermakers directly.) If the
width is too great, the fresh‑water flush package can also be remotely mounted.
WATER CONNECTIONS
The potable water in and the FWF water out connections
are on the fresh water flush assembly.
The
feed-water in and product-water out connections are installed on the right side of
the system. If the right side does not work for your installation, the connections can
be moved to the left side of the frame. The installation brackets exist on both sides.
USEFUL AMENITIES
Cable grips are provided for the various wires that will need to be run to the electrical
box. You will also find a service valve on the fresh‑water‑flush assembly to allow you
to change the filter without having to shutdown the onboard pressure system.
