6.4 Air Conditioning Pump
The air conditioner is self-contained and seawater cooled. An AC centrifugal raw water pump
supplies seawater that cools the condensing unit as it circulates through the system and is discharged
overboard. The pump is located in Q-Berth storage compartment and is activated whenever AC
current is available and the air conditioning system is operating.
Seawater is supplied to the pump from a thru-hull fitting located in the hull near the pump. A sea
strainer between the pump and thru-hull fitting protects the system from contaminants that could
damage the pump or the air conditioning system. Make sure the seawater pump receives adequate
seawater by periodically cleaning the sea strainer basket.
Please refer to the air conditioner owner's manual for more information on the operation and
maintenance of the air conditioner.
6.5 Raw Water System Maintenance
The following items should be done routinely to help maintain your raw water system:
• Check hoses, particularly the seawater supply lines, for signs of deterioration.
• Remove and clean the seawater strainers for the livewell, air conditioner and washdown pump,
as needed.
• Spray pumps and thru-hull valves with a protective oil periodically.
• The fishboxes and livewells should be drained and cleaned after each use.
• Operate all thru-hull valves at least once a month to keep them operating properly.
SHOULD A HOSE RUPTURE, TURN THE PUMP OFF IMMEDIATELY. AL-
WAYS CLOSE THE THRU-HULL VALVE WHEN PERFORMING MAINTE-
NANCE ON A SEAWATER PUMP.
THE BATTERIES MUST BE PROPERLY CHARGED. OPERATING ANY
PUMPS FROM A BATTERY WITH A LOW CHARGE MAY LEAD TO A
PUMP FAILURE.
THE RAW WATER SYSTEM MUST BE PROPERLY WINTERIZED PRIOR TO
WINTER LAY-UP. SEE THE SECTION ON WINTERIZING.
