    Installation Instructions

    1.  Power off the two-wire when installing any two-wire device. Leave 24 to 36 inches of slack in the two-wire at the connection point to allow for easy installation and maintenance.

    2.  Follow the instructions in the Netafim installation manual to install the flow meter.

    3.  Connect the red and black wires from the flow biCoders to the corresponding red and black wires from the two-wire path. Make certain to maintain polarity. All two-wire connections must have 3M™ DBR/Y-6 or equivalent moisture-resistant connectors.

    4.  Follow the instructions in the controller’s user manual to configure each device. For normally open master valves, configure the master valve as normally open in the controller as instructed in the controller’s user manual.
