FCI WATERMAKERS, INC. 103 Maintenance & Repair
INLET THRU HULL FITTING
This is a non FCI Watermakers component. Keep the inlet thru hull fitting free
and clear of debris and marine growth. If the inlet thru hull fitting is clogged, this
results in a low feed pressure condition, which causes the system to shut off.
Blockage at the inlet thru hull fitting causes the system to shut off due to lack of feed water
flow. Unfortunately, since it is under water, operators are reluctant to thoroughly inspect
the inlet thru hull fitting for problems. This can cause time‑consuming frustrations in
attempting to gain feed water flow by troubleshooting other components in the system.
The inlet thru hull fitting must be free and clear allowing the system to draw
4.5 U.S. Gallons Per Minute / 17 Liters Per Minute with minimal resistance.
Any blockage at the inlet thru hull fitting will cause low pressure and low flow
problems at the system. This inlet thru hull fitting must be a forward facing
scoop so that the system receives a positive flow of water as the boat is under
way. It must be minimum 3/4" inside diameter. It must be installed in a position
on the bottom of the hull so as to allow free flowing feed water without air.
CAUTION:
A flat profile, flush mount, inlet thru-hull fitting will cause
a vacuum as the boat is under way, and this will cause loss of feed water
flow and cavitation of pumps resulting in continual system shut down due
to low feed water flow and pressure. The resulting failure of the system to
remain in operation is attributed to improper installation, is the liability
of the installer, and is not covered by the FCI Watermakers warranty.
CAUTION:
If the thru-hull fitting has been placed in a position on the underside
of the hull that allows air to continually enter the thru-hull fitting, this will cause
the system to continually shut down due to loss of feed water. The resulting failure
of the system to remain in operation is attributed to improper installation, is the
liability of the installer, and is not covered by the FCI Watermakers warranty.
CAUTION:
The FCI Watermakers System must not be tied into another existing
auxiliary water line already supplying another accessory on the boat. Using one
thru hull fitting for other equipment will cause the FCI Watermakers System to
draw air, or cavitate, leading to continual system shut down. The resulting failure
of the system to remain in operation is attributed to improper installation, is the
liability of the installer, and is not covered by the FCI Watermakers warranty.
CAUTION:
If the FCI Watermakers System is connected to a sea chest or
stand pipe, do not plumb the FCI Watermakers System feed line to the “top”
of the sea chest or stand pipe. If plumbed into the top of these feed water
arrangements, the FCI Watermakers System will experience continual shut
down due to air inducement into the system. The resulting failure of the
system to remain in operation is attributed to improper installation, is the
liability of the installer, and is not covered by the FCI Watermakers warranty.
Plumb the FCI Watermakers System to the “bottom” of such feed water
arrangements to ensure a continual air free supply of feed water to the system .
The components are shown on the plumbing and interconnect
diagrams located in Installation chapter of this User’s Manual.
