GROUNDING
THE STEEL TANK (GARN WHS UNIT) MUST BE GROUNDED TO THE SAME POWER PANEL THAT SERVES THE ELECTRIC ELEMENTS. DEATH OR SEVERE INJURY MAY RESULT IF THE TANK IS NOT PROPERLTY GROUNDED.
PREVENTING ELECTROLYSIS CORROSION REQUIRES PROPER GROUNDING AND ELECTRIC ISOLATION GARN units no longer are supplied magnesium anode rods. The reason for this is many-fold; for further reading and explanation, please visit our Technical Service Bulletin page at: http://www.garn.com/technical-service-bulletins/
In addition, it is no longer recommended to ground the GARN tank with an independent ground rod. Specific grounding procedures must be followed.
1. Ground the GARN tank by attaching a properly sized ground wire to the steel mounting stud of the electric element box. 2. The grounding wire must go back to the panel (or ground rod – if directly connected to a utility meter) of the power service serving the sequencer.
DO NOT GROUND THE TANK TO ANY LOCATION OTHER THAN TO THE SAME LOCATION AS THE POWER SOURCE FOR THE ELECTRIC HEATING ELEMENTS.
