◦Intake and exhaust fan blade

■This SUNVENT model comes with two fan blades: intake and exhaust, intake fan blade is labeled "INTAKE"

■To exchange fan blade, simply pull the existing blade off and insert / push the new one. Care must be taken in pushing or pulling the fan blade so as not to bend the motor shaft; otherwise, its performance would be grossly affected

■If you have only one vent installed on your boat, we recommend using only the exhaust fan blade. If you have multiple vents, try different configurations of intake and exhaust to achieve effective cross flow ventilation

◦Shut-off Bottom Cover: These models of SUNVENT are equipped with bottom cover to shut-off from below. When not in use, it is advisable that one covers the fan outlet with bottom cover.
