Note ! The AP21 cable contains an air-breathing tube. Check that the
tube is open after you have cut the cable.
JP21 Jack Point installation
The JP21 can be used in conjunction with the AP21 control units.
It provides a quick and simple means of connection/
disconnection of the AP21 at different locations on the boat.
The JP21 includes a watertight connector cover which must be
installed as shown. A 32 mm (1,26” dia.) hole needs to be drilled
for flush installation, along with 3 small screw holes. As
indicated, a watertight sealant must be applied to the mating
surfaces of the JP21 and the mounting panel. Also apply a thin
layer of Vaseline on the O-ring seal.
