NOTICE
Most air conditioners utilize surface water as
the cooling medium. Prior to using the air
conditioning, the boat must be in the water and
the seacock to the air conditioning water intake
must be in the open position. The air
conditioning seacock for water intake is below
the aft cabin access panel. Operating air
conditioners without proper cooling water will
cause damage to the air conditioning system.
