Incorporate this inspection into commissioning
procedure in spring and winterizing procedure in fall.
A removable magnesium Anode is integral with the
hot water discharge fitting. The Anode should be
checked at least once a year by removing it from the
water heater. If the Anode diameter is less than 3/8"
(9.5mm), it should be replaced. If discoloration,
unusual smell or taste develop in the water, inspect or
replace Anode. The Anode is replaceable as a unit
and may be ordered from Raritan dealers or from the
factory. Please specify 6, 12, or 20 gallon model.
