ensure that the product is working properly
and safely. The valve must not be clogged or
blocked. Any scale must be removed.
REGULAR MAINTENANCE
Scale forms in time during normal use on
the surface of the heater element. Such
deposits reduce the transfer of heat between
the heater element and the water. A higher
surface temperature on the heater element is
required to heat the water. The thermostat will
switch on and off more often. The overheating
protection can trip. The manufacturer
recommends preventive maintenance every
other year by an authorised service centre
to avoid such problems. Such preventive
maintenance should include cleaning and
checking the sacrificial anode. The sacrificial
anode should be replaced when necessary.
SACRIFICIAL MAGNESIUM ANODE
FOR CORROSION PROTECTION
The magnesium sacrificial anode protects
the inside of the water tank from corrosion.
The anode becomes consumed in time and
must be replaced at regular intervals.
The manufacturer recommends that qualified
personnel check the anode at regular intervals
and replace it when necessary for best results
and life span. This check should be included
in the regular preventive maintenance of the
product. Contact an authorised service centre
for replacement anodes.
