DIMENSIONS

WIRING

MOUNT COMPASS

Point™-1AP™ and Precision™-9 compasses contain a magnetic heading sensor and should be mounted away from magnetic interference. The sensor should be mounted as level as possible in a location close to the vessel’s center of pitch and roll. Point™-1AP™ also contains a GPS antenna. The sensor should be mounted in a location with a clear view of the sky and horizon away from electromagnetic interference. Potential sources of magnetic or electromagnetic interference include:

• Electrical motors, magnets, and moving metal items
• Outboard engines
• High current electrical sources such as main power cables, batteries, and distribution panels
• Audio speakers
• Radars
• Xenon search lights
• VHF antennas

PRECISION™-9

CONNECTING

CONNECT HOSES TO HELM

Note: You can connect tee connectors to the pump if space is limited behind the helm.

CONNECT HOSES TO PUMP-1

Note: You can connect tee connectors to the pump if space is limited behind the helm.

BLEED HYDRAULIC SYSTEM

1. Slowly turn the wheel until the hydraulic cylinder stops, wait for a few seconds, and turn the wheel in the opposite direction until the hydraulic cylinder stops again. You may notice air being expelled from the filling port. Add more hydraulic fluid if the level is insufficient.
2. Continue turning the wheel and adding hydraulic fluid until the level is stable and the outboard engine responds firmly.
3. If air bubbles remain in the hydraulic system, follow the bleeding procedure described for your hydraulic cylinder.

Note: It is recommended you use a threaded filler tube to avoid spillage.

BLEED PUMP-1

1. Activate non follow up mode on the Autopilot controller.
2. Press the Autopilot controller arrow keys for 3 seconds at a time, until the cylinder stops.
3. Wait for a few seconds, and repeat in the opposite direction until the hydraulic cylinder stops again.
4. Repeat in both directions until there are no air bubbles visible in the transparent tube.
5. Check the fluid level is filled to the manufacturer’s specification.
6. Check all fittings for leaks after 24 hours.

COMMISSIONING

Refer to your Autopilot controller’s documentation for commissioning instructions.
