If all connections are not sealed, excess moisture accumulation can damage the
transmitter. Ensure to mount the transmitter with the electrical housing positioned
downward for drainage. To avoid moisture accumulation in the housing, install wiring with
a drip loop, and ensure the bottom of the drip loop is mounted lower than the conduit
connections or the transmitter housing.
