Garnet Instruments 709-P3W Installation guide

  • I've reviewed the provided Wiring Diagram document for the 709-P3W system, which details the wiring connections for various components, including the pump switch, LPG sensor, and tank senders. The document also highlights important safety precautions, such as fusing power circuits. I'm ready to answer your questions about this diagram and the device.
  • What is the purpose of the LPG Green wire?
    What is the maximum fuse rating for the power circuits?
    When is a relay required for the pump?

W WARNING: All power circuits must be fused.
If a fuse is not provided with the system then it is the
installer’s responsibility to install a fuse with the
maximum rating of 10 amps. A relay is required if
more than 10 amps needed for the pump.
