4.5 Bleeding air
To avoid damage to the transducer by the transmission in air
inside the trunk, a pipe with a minimum inside diameter of 10
mm must be attached to the air bleeding cock. This vent should
be run with continuous rise to the main deck or through the
vessel’s side. Make sure the air bleeding cock is opened.
