UALITY
A replaceable metal anode comes installed in a threaded port near the water-jacket fill port on the back
of the unit. The anode dissolves when in contact with the mineral salts and dissolved gases found in tap
water. This helps to protect the liner of the water jacket from corrosion well as well as scaling and other
mineral deposits. When 50% of the anode has eroded away a new anode must be installed.
Tap water with a hardness of more than 30 parts per million or 1.5 grains per gallon
will require
assessment of the anode on a yearly basis
. Dissolved gases in tap water used in the water jacket
should never exceed more than 120 parts per million or 7 grains per gallon. The pH of the water should
be between 6.0 and 8.5.
Use distilled water if possible
. Never use deionized water.
