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.
