6 Turn on the autopilot system and disable the Shadow Drive.You can refer to the autopilot system documentation for moreinformation on disabling the Shadow Drive.7 Hold (port) on the helm control for at least 10 seconds.TIP: You can stop holding when you no longer see airmoving through the bypass hose.8 Close both bypass valves at the cylinder fittings.9 If necessary, add fluid to the helm reservoir.10Repeat steps 3 through 9 for the starboard side.11Hold (port) on the helm control until steering stops andHydraulic Pump Stall is shown on the helm control.12Hold (starboard) on the helm control until steering stopsand Hydraulic Pump Stall is shown on the helm control.13Select an option:• If Hydraulic Pump Stall is not shown within 2 to 3seconds after the cylinder stops, repeat steps 1-13 tobleed the system again.• If Hydraulic Pump Stall is shown within 2 to 3 secondsafter the cylinder stops, the system bleed completedsuccessfully.After hydraulic bleeding is complete, you can re-enable theShadow Drive.Corrosion BlockerNOTICETo ensure the long life of all parts, apply corrosion blocker to thepump at least twice yearly.A marine-rated corrosion blocker should be applied to the pumpafter all hydraulic and electrical connections are made and thehydraulic system has been bled.Connecting the CCURoute the orange and blue wires from the bare-wire portionof the CCU cable to the location where you plan to install thealarm (Installing the Alarm, page 8).If the cable is not long enough, extend the appropriate wireswith 0.08 mm2 (28 AWG) wire.Installing the Shadow DriveConnecting the Shadow Drive to the Hydraulic SystemBefore you can install the Shadow Drive, you must select alocation at which to connect the Shadow Drive to the hydraulicsteering of your boat (Shadow Drive Mounting Considerations,page 2).For further assistance, consult the hydraulic-layout diagrams(Hydraulic Layouts, page 4).Use hydraulic connectors (not included) to install the ShadowDrive in the appropriate hydraulic line.Connecting the Shadow Drive to the CCU1 Route the bare-wire end of the CCU cable to the ShadowDrive.If the cable is not long enough, extend the appropriate wireswith 28 AWG (0.08 mm²) wire.2 Connect the cables, based on this table.Shadow Drive Wire Color CCU Cable Wire ColorRed (+) Brown (+)Black (-) Black (-)3 Solder and cover all bare-wire connections.Installing an Autopilot SwitchIf your autopilot package does not include a Shadow Drivevalve, you should install a manual Single Pole Single Throw(SPST) switch (not included) to disable the autopilot ifnecessary.1 Route the bare-wire end of the CCU cable to the switch.If the cable is not long enough, extend the appropriate wireswith 28 AWG (0.08 mm²) wire.2 Connect the cables, based on this table.Switch Wire Function CCU Cable Wire ColorPositive (+) Brown (+)Negative (-) Black (-)3 Solder and cover all bare-wire connections.The autopilot functions correctly when the switch contacts areclosed. Opening the switch disables the autopilot for manualsteering.Installing the AlarmBefore you can mount the alarm, you must select a mountinglocation (Alarm Mounting and Connection Considerations,page 2).1 Route the alarm cable to the bare-wire end of the CCU cable.If the cable is not long enough, extend the appropriate wireswith 28 AWG (0.08 mm2) wire.2 Connect the cables, based on this table.Alarm Wire Color CCU Cable Wire ColorWhite (+) Orange (+)Black (-) Blue (-)3 Solder and cover all bare-wire connections.4 Secure the alarm with cable ties or other mounting hardware(not included).NMEA 2000 and the Autopilot ComponentsA dedicated helm control is not included in all autopilotpackages. If you install the autopilot without a dedicated helmcontrol, the autopilot CCU must be connected to the sameNMEA 2000 network as a compatible Garmin chartplotter toconfigure and control the autopilot system.NOTICEIf you have an existing NMEA 2000 network on your boat, itshould already be connected to power. Do not connect theNMEA 2000 power cable to an existing NMEA 2000 network,because only one power source should be connected to aNMEA 2000 network.You can connect the CCU and the optional helm control throughan existing NMEA 2000 network. If you do not have an existingNMEA 2000 network on your boat, all the parts needed to buildone are supplied in the autopilot package (Building a BasicNMEA 2000 Network for the Autopilot System, page 8).To use the advanced features of the autopilot, optional NMEA2000 devices, such as a GPS device, can be connected to theNMEA 2000 network.If you are unfamiliar with NMEA 2000, you should read the“NMEA 2000 Network Fundamentals” chapter of the TechnicalReference for NMEA 2000 Products.Building a Basic NMEA 2000 Network for the AutopilotSystemNOTICEIf you are installing a NMEA 2000 power cable, you mustconnect it to the boat ignition switch or through another in-lineswitch. NMEA 2000 devices will drain your battery if the NMEA2000 power cable is connected to the battery directly.A dedicated helm control is not included in all autopilotpackages. If you install the autopilot without a dedicated helmcontrol, the autopilot CCU must be connected to the sameNMEA 2000 network as a compatible Garmin chartplotter toconfigure and control the autopilot system.8
