Important information
Safety notices
WARNING
Intended use
A properly installed and operated hydraulic pump as part of an autopilot
system is designed to be used only as a backup to a vessel’s existing
primary steering system. The autopilot system is NOT intended or
warranted to be used as a replacement for the primary steering system.
WARNING
Product installation
This equipment must be installed in accordance with the instructions
contained in this handbook. Failure to do so could result in poor product
performance, personal injury and/or damage to your boat.
Because correct performance of the boat’s steering is critical for safety, we
STRONGLY RECOMMEND that an Authorized Raymarine Service
Representative fits this product.
WARNING
Navigation aid
When this product is used within a navigation system, it is only an aid to
navigation. It’s accuracy can be affected by many factors, including
equipment failure or defects, environmental conditions and improper use
or handling. It is the user’s responsibility to exercise common prudence
and navigational judgements. This product should not be relied upon as a
substitute for such prudence and judgement. Always maintain a permanent
watch so that you can respond to situations as they develop.

EMC installation guidelines
Raymarine equipment and accessories conform to the appropriate
Electromagnetic Compatibility (EMC) regulations, to minimize electromagnetic
interference between equipment and minimize the effect such interference
could have on the performance of your system.
Correct installation is required to ensure that EMC performance is not
compromised.
For optimum EMC performance we recommend that wherever possible:
• Raymarine equipment and cables connected to it are:
• At least 1 m (3ft) away from any equipment transmitting or cables carry-
ing radio signals e.g. VHF radios, cables and antennas. In the case of
SSB radios, the distance should be increased to 7 ft (2 m).
• More than 2 m (7 ft) from the path of a radar beam. A radar beam can nor-
mally be assumed to spread 20 degrees above and below the radiating
element.
• The product is supplied from a separate battery from that used for engine
start. This is important to prevent erratic behavior and data loss which can
occur if the engine start does not have a separate battery.
• Raymarine specified cables are used.
• Cables are not cut or extended, unless doing so is detailed in the installation
manual.
• The EMC filter box must not be removed from the motor cable.
Note: Where constraints on the installation prevent any of the above recommendations,
always ensure the maximum possible separation between different items of electrical
equipment, to provide the best conditions for EMC performance throughout the installa-
tion.
WARNING
Ensure cleanliness
Absolute cleanliness is essential when working with hydraulic systems.
Even the smallest dirt particle could prevent the steering system check
valves from working correctly. Ensure that no dirt enters the system during
the installation, and that all hoses and fittings are cleaned before making
any connections.

Connections to other equipment
If your Raymarine equipment is to be connected to other equipment using a
cable not supplied by Raymarine, a suppression ferrite MUST always be
attached to the cable near to the Raymarine unit.

Introduction
Product description
The Raymarine hydraulic pump (also known as the Raymarine constant
runninng hydraulic pump) is intended to operate a vessel’s steering mechanism
as part of a Raymarine autopilot system. It is primarily designed for use on
vessels with an existing hydraulic steering system. Alternatively, you can use
this pump on a vessel with mechanical steering in conjunction with a secondary
steering ram.
Raymarine pumps are driven by 12 or 24 V dc permanent magnet motors. The
pumps include pilot-operated check valves that prevent the pump being back
driven by the manual steering system or rudder load. The motors can be
removed from the pump without allowing air into the hydraulic system or fluid to
escape. The pumps also include compatibility with balanced or unbalanced
cylinders and can be used with pressurised reservoir systems.
