1. For solar operation, install the sensor well into the
brass elbow and connect the assembly to the solar
return line.
2. Insert the temperature sensor until it bottoms out
inside the sensor well.
IMPORTANT
Never wrap insulating tape around the sensor. Do not
install solar tank sensor anywhere other than the brass
elbow with sensor well.
IMPORTANT
When connecting an externally powered anode to the top
flange lid, separate the magnesium anode in the bottom
flange lid from the grounding cable. The magnesium anode
may remain installed.
