STORAGE CYLINDER MAINTENANCE AND MAGNESIUM ANODE REPLACEMENT
Check the magnesium anode inside the D.H.W.
storage cylinder for erosion, a minimum of every
12 months or more frequently in case of hard water
or continuous operation. If it is worn-out, replace it
immediately. A non correct maintenance will
invalidate the cylinder warranty.
To check the anode, unscrew the anode nut
located on the top of the cylinder (see fig.3) by
turning it counter-clockwise. If, at the opening of
the valve, water comes out of the valve, the anode
is worn and needs to be replaced; if no water
comes out of the valve, the anode is not worn and
therefore still functioning.
Once this operation
has been completed, close the small valve.
