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. ALWAYS
CLOSE THE THRU HULL VALVE WHEN PERFORMING MAINTENANCE ON A SEA-
WATER 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 WIN-
TER LAY-UP. SEE THE SECTION ON WINTERIZING.
