Mounting and Connection Considerations
The autopilot components connect to each other and to power using the included cables. Ensure that the correct cables reach each component and that each component is in an acceptable location before mounting or wiring any components.

CCU Mounting and Connection Considerations

• The CCU is the primary sensor of the Compact Reactor 40 Hydraulic autopilot system. For best performance, observe these considerations when selecting a mounting location.

  • A handheld compass should be used to test for magnetic interference in the area where the CCU is to be mounted(Testing a Location for Magnetic Interference, page 7).
  • The CCU should be mounted on a rigid surface for best performance.

• Mounting screws are provided with the CCU. If you use mounting hardware other than the provided screws, the hardware must be quality stainless or brass material to avoid magnetic interference with the CCU.
  Test any mounting hardware with a handheld compass to make sure no magnetic fields are present in the hardware.

• The CCU cable connects the CCU to the ECU and is 5 m (16 ft.) long.

  • If the CCU cannot be mounted within 5 m (16 ft.) of the ECU, extension cables are available from your local Garmin dealer or at garmin.com.
    ◦ This cable must not be cut.

Finding the Best Mounting Location

1. Create a list of all suitable mounting locations for the CCU.
   Suitable mounting locations should not be within 60 cm (2 ft.) of the following:

   • Iron
   • Magnets
   • High-current wires
   • Intermittently-running pumps, such as head pumps and live well pumps
     A large magnet, such as a subwoofer-speaker magnet, should be no closer than 1.5 m (5 ft.) to any of the mounting locations.

2. Locate the center of rotation of the boat, and measure the distance between the center of rotation and each of the suitable mounting locations you listed in step 1.

3. Select the location closest to the center of rotation.
   If more than one location is approximately the same distance from the center of rotation, you should select the location that best meets these considerations.

   • The best location is closest to the centerline of the boat.
   • The best location is lower in the boat.
   • The best location is slightly forward in the boat.

Testing a Location for Magnetic Interference
You can use a handheld compass to test a mounting location for magnetic interference.

1. Hold a handheld compass in the CCU mounting location.
2. Move the compass six inches to the left of the location, then six inches to the right, observe the needle, and select an action:
   • If the compass needle moves more than three degrees during this step, magnetic interference is present. Select a new mounting location and repeat the test.
   • If the compass needle does not move, or moves less than three degrees, proceed to the next step.
3. Repeat this process while moving the compass above and below the mounting location.
4. Repeat this process while moving the compass in front of and behind the mounting location.

ECU Mounting and Connection Considerations

• The ECU can be mounted on a flat surface, facing any direction.
• Mounting screws are included with the ECU, but you may need to provide different screws if the supplied screws are not suitable for the mounting surface.
• The ECU must be mounted within 0.5 m (19 in.) of the pump.
  • The cables connecting the ECU to the pump cannot be extended.
• The ECU must be mounted in a location where it will not be submerged or exposed to wash down.
• The ECU power cable connects to the boat battery, and it can be extended if needed (Power Cable Extensions, ).

Pump Mounting Considerations
Consult the hydraulic-layout diagrams in these instructions to help determine the pump-installation location(Hydraulic Layouts, ).

• The pump must be mounted at a location to which you can extend the hydraulic steering lines of the boat.
• The pump should be mounted horizontally if possible.
• If the pump must be mounted vertically, with the hydraulic connections facing upward.

Shadow Drive Sensor Mounting Considerations
NOTE: The Shadow Drive sensor is a device you install in the hydraulic steering lines of your boat. It detects when you manually take control of the helm and suspends autopilot control of the boat.

• The Shadow Drive sensor must be mounted horizontally and as level as possible, with cable ties firmly securing it in place.

• The Shadow Drive sensor must be mounted at least 305 mm (12 in.) away from magnetic materials or devices, such as speakers or electric motors.

• The Shadow Drive sensor should be mounted closer to the helm than to the pump.

• The Shadow Drive sensor should be mounted lower than the lowest helm, but higher than the pump.

• The Shadow Drive sensor must not be connected directly to the fitting at the back of the helm. There must be a length of hose between the fitting at the helm and the Shadow Drive sensor.

•  The Shadow Drive sensor must not be connected directly to a hydraulic T-connector in the hydraulic line. There must be a length of hose between a T-connector and the Shadow Drive sensor.

• In a single-helm installation, there must not be a T-connector between the helm and the Shadow Drive sensor.

• In a dual-helm installation, the Shadow Drive sensor should be installed between the pump and the hydraulic
  T- connector that leads to the upper and lower helm, closer to the T-connector than to the pump.

• The Shadow Drive sensor must be installed in either the starboard steering line or the port steering line.
  The Shadow Drive sensor must not be installed in either the return line or the high-pressure line, if applicable.

Alarm Mounting and Connection Considerations

• The alarm should be mounted near the primary helm station.
• The alarm can be mounted under the dashboard.
• If needed, the alarm wires can be extended with 28 AWG (0.08 mm2) wire.

NMEA 2000 Connection Considerations

• The CCU and the helm control must connect to a NMEA 2000 network.
• If your boat does not already have a NMEA 2000 network, one can be built using the included NMEA 2000 cables and connectors (Building a Basic NMEA 2000 Network for the Autopilot System, page 17).
• To use the advanced features of the autopilot, optional NMEA 2000 devices, such as a wind sensor, a water-speed sensor, or a GPS device, can be connected to the NMEA 2000 network.

Hydraulic Layouts

NOTICE
If the steering system in your boat does not match any of the hydraulic layouts in this manual and you are unsure how to install the pump, contact Garmin Product Support.

Before you start the pump installation, identify the type of hydraulic steering system in your boat. Each boat is different, and you must consider certain aspects of the existing hydraulic layout before deciding where to mount the pump.

Before you start the pump installation, you should thoroughly review the hydraulic considerations for important information on hydraulic hose and fitting types, installation methods, and thread-sealant information.

Important Considerations

• The three hydraulic ports on the pump are 1/4 in. NPT.
• You should use T-connectors (not included) to connect the hydraulic lines to the pump.
• To allow for easy pump isolation and removal, you should install shut-off valves (not included) in the hydraulic lines between the pump manifold and T-connectors.
• An appropriate thread sealant should be used on all pipe threads in the hydraulic system.

Installation Procedures

CAUTION
To avoid possible personal injury, always wear safety goggles, ear protection, and a dust mask when drilling, cutting, or sanding.

NOTICE
When drilling or cutting, always check what is on the opposite side of the surface to avoid damaging the vessel.

After you have planned the autopilot installation on your boat and satisfied all of the mounting and wiring considerations for your particular installation, you can begin mounting and connecting the components.

Helm Control Installation
A dedicated helm control is not included in all autopilot packages. If you install the autopilot without a dedicated helm control, the autopilot CCU must be connected to the same NMEA 2000 network as a compatible Garmin chart plotter to configure and control the autopilot system.
Detailed mounting instructions are included in the helm control box.

Mounting the CCU

1. Determine the mounting location.
2. Using the CCU as a template, mark the two pilot hole locations on the mounting surface.
3. Using a 3 mm (1/8 in.) bit, drill the pilot holes.
4. Use the included screws to attach the CCU to the mounting surface.

NOTE: If you use mounting hardware other than the provided screws, the hardware must be quality stainless or brass material to avoid magnetic interference with the CCU.
Test any mounting hardware with a handheld compass to make sure no magnetic fields are present in the hardware.

ECU Installation
Mounting the ECU
Before you can mount the ECU, you must select a location and determine the correct mounting hardware (ECU Mounting and Connection Considerations,).

1. Hold the ECU in the intended mounting location and mark the locations of the mounting holes on the mounting surface, using the ECU as a template.
2. Using a drill bit appropriate for the mounting surface and selected mounting hardware, drill the four holes through the mounting surface.
3. Secure the ECU to the mounting surface using the selected mounting hardware.

Connecting the ECU to Power

WARNING
When connecting the power cable, do not remove the in-line fuse holder. To prevent the possibility of injury or product damage caused by fire or overheating, the appropriate fuse must be in place as indicated in the product specifications. In addition, connecting the power cable without the appropriate fuse in place voids the product warranty.

You should connect the ECU power cable directly to the boat battery, if possible. Although it is not recommended, if you connect the power cable to a terminal block or other source, you must connect it through a 40 A fuse.

If you plan to route the ECU power through a breaker or a switch near the helm, you should consider using an appropriately sized relay and control wire instead of extending the ECU power cable.

1. Route the connector-terminated end of the ECU power cable to the ECU, but do not connect it to the ECU.

2. Route the bare-wire end of the ECU power cable to the boat battery.
   If the wire is not long enough, it can be extended (Power Cable Extensions, page 12).

3. Connect the black wire (-) to the negative (-) terminal of the battery, and connect the red wire (+) to the positive (+) terminal of the battery.

4. After you install all of the other autopilot components, connect the power cable to the ECU.

NOTICE
You should apply dielectric grease to the pin holes on the cable connector to prevent corrosion, especially if you are using the autopilot system in saltwater.

Power Cable Extensions
If necessary, you can extend the power cable using the appropriate wire gauge for the length of the extension.

Pump Installation

Mounting the Pump
Before you can mount the pump, you must select a location (Pump Mounting Considerations, page 8) and determine the correct mounting hardware (Tools and Supplies Needed, page 2).

1. Hold the pump in the intended mounting location and mark the locations of the mounting holes on the mounting surface, using the pump as a template.

Bleeding the Hydraulics
NOTICE
This is a general procedure for bleeding a hydraulic steering system.
Refer to the instructions provided by the manufacturer of the steering system for more-specific information about bleeding the system.

Before you bleed the hydraulic system, you should verify that all hose connections are complete and fully tightened.

1. Select an option:

   • If the helm reservoir contains insufficient fluid, fill it as needed.
   • If the helm reservoir contains excess fluid, remove the excess to avoid fluid overflow during the bleeding process.

2. Insert a bypass hose between the cylinder bleed ports.
   TIP: If you use a clear plastic hose for this bypass, you can observe air bubbles during the bleeding processes.

3. Manually steer the helm fully to port.

4. Open both bypass valves at the cylinder fittings.

5. Manually turn the helm slowly to port over three minutes.
   TIP: You can stop turning when you no longer see air moving through the bypass hose.

6. Turn on the autopilot system and disable the Shadow Drive sensor.
   You can refer to the owner’s manual for your helm control or chart plotter for more information on disabling the Shadow Drive.

7. Hold <1° (port) on the helm control or chart plotter for at least 10 seconds.
   TIP: You can stop holding <1° when you no longer see air moving through the bypass hose.

8. Close both bypass valves at the cylinder fittings.

9. If necessary, add fluid to the helm reservoir.

10. Repeat steps 3 through 9 for the starboard side.

11. Hold <1° (port) on the helm control or chart plotter until steering stops and Hydraulic Pump Stall appears. 12 Hold 1°> (starboard) on the helm control or chart plotter until steering stops and Hydraulic Pump Stall appears.

12. Select an option:

    • If Hydraulic Pump Stall dowse not appear within 2 to 3 seconds after the cylinder stops, repeat steps 1-13 to bleed the system again.
    • If Hydraulic Pump Stall appears within 2 to 3 seconds after the cylinder stops, the system bleed completed successfully.

After hydraulic bleeding is complete, you can re-enable the Shadow Drive sensor.

Configuration
The autopilot must be configured and tuned to your boat dynamics.
You can use the Dockside Wizard and the Sea Trial Wizard on the helm control or a compatible Garmin chart plotter to configure the autopilot.
See the included configuration guide for more information on configuring the autopilot.
