SEA CHEST FILTRATION SYSTEM
The optional sea chest system requires very little
maintenance. All hardware including hose clamps and
hoses should be inspected periodically for abrasion and
leaks. Check all electrical connections for tightness.
Periodic inspection of the fi lter basket is recommended.
Close the inlet and discharge seacocks and shut power off
at the ship's main DC panel before removing the cover to
inspect the fi lter basket.
To access the cover, remove the cotter pin and release the
band clamp that holds the cover in place. Reverse process
for reassembly. When fi nished, turn on power and check
for leaks while running the system.

The 230 volt air conditioner pump uses fi ltered water from
the sea chest system (if installed) and pumps it to the A/C

condenser units. Check each air conditioner thru-hull for
water output once the pump activates. Shut the unit down
if little or no water is observed.
