SEA COCK VALVE
This is a non‑FCI Watermakers component. The packing and connections of the inlet
sea cock valve must be tight and must properly seal. Clean the valve cavity of debris or
replace the seal and seat or the entire valve, as required. This section is under a vacuum
condition while operating the system. Loose fittings or a worn seal will allow air to enter
the system causing continual shut down due to subsequent low feed water pressure.
SEA STRAINER
Keep the mesh screen free and clear of debris. When the mesh screen is clogged,
it results in a low‑pressure condition causing system shut off. This section is
under a vacuum condition while operating the system. If the sea strainer's bowl is
loose or if the O‑ring seal is worn or not properly seated, air will enter the system
causing continual shut down due to subsequent low feed water pressure.
INLET CONNECTION
Replace if damaged.
INLET ACTUATED VALVE (if equipped)
The actuated valve is comprised of a 2‑way union ball valve with an actuated motor drive
on top. The valve is equipped with a post on the top that indicates the valve position
(open / closed). If the valve does not open, turn power off to the system and loosen the
union nuts. If they nuts are too tight it will inhibit the ball from being able to turn freely.
If after the power is applied the valve will still not actuate, check all wiring connections.
