Solution : Clean all marine growth and debris from
the Inlet Thru-Hull Fitting.
System is newly installed and operation is being
performed for the first time. The feed water
pressure is low and insufficient to keep the
System in operation.
A NEW boat, or newly installed System, may have
protective shipping tape covering the Inlet Thru-
Hull Fitting. A New boat, or newly installed System,
may have manufacturing debris such as caulking
slopped over the Inlet Thru Hull or a rag may be
stuffed into the Inlet Thru-Hull fitting. A NEW Inlet
Thru-Hull Fitting may have casting slag, that has
not been machined off, partially covering the
“fingers” or the inside of the fitting.
Solution : Inspect the Inlet Thru-Hull Fitting and
clean all manufacturing debris and casting slag
from the fitting.
2) SEA COCK VALVE
The Sea Cock Valve is usually a 1/4 turn Ball
Valve although any positive closing and opening valve is
acceptable.
Problems and Symptoms appearing and caused by the
SEA COCK VALVE:
a)
The Sea Cock Valve is closed when attempting to
Start the System.
System does not register feed water flow and feed
water pressure when attempting to start. An error
screen appears and the System shuts down.
When the System is not in use it is good practice,
for the safety of the Boat, to close the Sea Cock
Valve. Don’t forget to open it prior to starting the
System.
Solution : Open the Sea Cock Valve.
b) The Sea Cock Valve seal is worn or the seal is
loose causing air to enter the System Feed Line.
System feed water pressure is low and insufficient
to keep the System in operation. This section of
the Feed Line is under a vacuum condition when
the System is in operation. If the valve’s seal is
worn or loose air can enter the feed line causing
the System to lose pressure.
Look for air bubbles moving through the Sea
Strainer, or feed line.
Solution : Change the valve seals, tighten
them, or if necessary replace the valve.
attributed to improper installation, is the
liability of the installer, and is not covered
by the Sea Recovery warranty.
CAUTION ! If the Sea Recovery
System is connected to a Sea Chest or
Stand Up Pipe, do not plumb the Sea
Recovery System feed line to the “top”
of the Sea Chest or Stand Up Pipe. If
plumbed into the top of these feed water
arrangements, the Sea Recovery 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 Sea Recovery
warranty. Plumb the Sea Recovery System
to the “bottom” of such feed water
arrangements to ensure a continual air free
supply of feed water to the system.
1) THRU-HULL INLET FITTING
Problems and Symptoms appearing and caused by the
THRU-HULL INLET FITTING:
a)
Flat profile Inlet Thru Hull Fitting:
System runs fine when at anchor. However,
when under way the System shuts off due to low
pressure or low feed water flow.
A flat profile Inlet Thru Hull Fitting will cause a
vacuum at the System’s feed line cavitating the
Booster Pump and reducing the efficiency of the
Booster Pump resulting in low feed water pressure
and low feed water flow.
Solution
:
Change the flat profile Thru Hull Fitting to a
forward facing scoop.
b) Debris is blocking the Inlet Thru Hull Fitting:
System feed water pressure is low and insufficient
to keep the System in operation.
Marine growth or debris such as a plastic bag or
rag covering the Inlet Thru-Hull Fitting will cause
a vacuum at the System’s feed line cavitating the
Booster Pump and reducing the efficiency of the
Booster Pump resulting in low feed water pressure
and low feed water flow.
