Garmin TR-1 manual Installation Of Shadow Drive Valve Single Helm Station, Electrical Connections

Installation Of Shadow Drive Valve (Single Helm Station)

Shadow Drive Valve/Sensor: The Shadow Drive is an electronic bi-directional valve. Install it as shown in the system layout.Install it horizontally, as level as possible, and mount the valve lower than the helm. Avoid any loops in the hydraulic lines, air may get trapped and cause the autopilot not to work properly. It needs to be mounted closer to

the helm than to the pump unit.

Do Not mount the Shadow Drive Valve within 12” of any magnetic interference such as speakers or pump motors.

Do Not Install valve directly to the fittings at the back of the helm, it will damage the helm. Be sure to install a length of hose between the fitting at the helm and the Shadow Drive valve. TR-1 recommends a length of hose between Shadow Drive and any Tee. In a single helm installation, do not place a tee in the line between the helm and Shadow Drive Valve. This is very important for the Shadow Drive feature to work correctly. Air can and will get trapped in the valve during installation and bleeding. It’s very important to get all the air out of the Hydraulic Lines, Helms, Pump, Cylinder(s) and The Shadow Drive valve.

Do Not Install the Shadow Drive in the return or compensating line.

Do Not use teflon tape on hydraulic fittings. However, for a leak free hydraulic system, we do advise you to use an appropriate thread sealant such as, Loctite “Pro Lock” multipurpose anacrobic gel, part number 51604, or equivalent on all pipe threads.
