IMPORTANT SAFETY INFORMATION Failure to install and maintain this equipment in accordance with the in- structions contained in this Manual could result in damage or injury. This equipment must be installed and maintained by a person who is qualified to do so. This equipment is only for use with marine auto pilots within the limitations stated in the following pages. - Page 5 DESCRIPTION "PR+RU" reversing type gear pumps are driven by 12 or 24 volt DC permanent magnet motors. Incorporated in the design are pilot operated check valves that prevent the pump being back driven by the manual steering system or rudder load. The motors have an IP67 rating and can be removed from the pump without allowing air into the hydraulic system or fluid to escape.

Page 8: Pump Selection
PUMP SELECTION It is important to select the correct size PR+RU pump as it directly influences the steering performance and power consumption. The type of vessel to be steered must be considered. The hard-over time may need to be faster on lightweight planing craft and modern yachts or slower on displacement power boats or long keel yachts. - Page 9 LOCATION The PR+RU pump is designed for “Under Deck” installations only. When considering where to mount the pump the following points should be taken into account. Keep hose and cable runs short. Mount away from sources of heat. Install the pump above areas liable to flooding. Use a solid surface to prevent noise transmission and amplification.
