16 CR Hydraulic Pump - Installation Guide
Commissioning
System Check
WARNING:
Keep clear of moving steering systems at all times. Protect
moving parts from access during normal use.
Check the following points after installing the pump:
1. Is the pump installed as close to the steering ram as possible?
2. Is the pump secured to a substantial structure on the boat?
3. Have you connected a third hydraulic pipe between the helm pump and auto-
pilot pump?
4. Have you fitted check valves where appropriate?
5. Are the hydraulic pipes made of a suitable flexible material (i.e. rubber or
nylon) with a suitable pressure rating?
6. Have you sealed all hydraulic connections and checked for leakages?
7. Are power cables correctly routed and securely connected to the course com-
puter?
You have now finished installing the pump. After installing the rest of the
autopilot you must bleed all air from the system (see below).
Note:
When you have installed the entire autopilot system, you will also need to complete
an autopilot steering check. Refer to the control unit handbook for more details.
Bleeding the system
Bleeding the hydraulic system correctly is one of the most important steps when
installing the autopilot hydraulic pump. If there is any air in the system the
steering will feel spongy, particularly when you turn the wheel to hardover.
CAUTION:
Any air in the hydraulic system will greatly reduce the
performance of the autopilot and the overall steering system.
In addition to the manufacturer’s instructions for bleeding the steering system,
follow these steps to bleed the autopilot pump when you have installed and set
up the rest of the autopilot system:
1. With the system in auto mode, press the -10 button ten times:
the autopilot pump will try to drive the rudder to port
counter this rudder movement by turning the helm to starboard to keep
the rudder stationary
