10. Maintenance
Before performing any type of maintenance or any other non regular action, turn off the
device by disconnecting the plug from the outlet and wait until the heating elements will
be cooled. It is reccomended the cleaning of the tank at least each two years (depending
on the water hardness). Magnesium anode must be replaced each 2 years.
11. Protection against limestone
Presidential decree of 2nd April 2009 entered in force 25th of June 2009, made
compulsory the instalation of water softening systems (if limestone concentration in
water is high), in order to protect hot water production devices of the house.
The obligation does not affect all houses, but exclusively those where the temporary
water hardness is equal or superior to 25 french degrees (heating systems) and to 15
french degrees (hot water systems).
Water hardness is generally expressed in french degrees (°f, do not confuse with °F,
which are Fahrenheit degrees), where one degree represents 10 mg of calciumcarbonate
for a litre of water. Presently, it is used also MEC degree, corresponding to 1g calcium
carbonate in 100 l and is therefore equal to to a french degree. Generally, the waters are
classified basing on their hardness as following:
