expansion of the water.
Check that joints and seals are watertight. In the course of heating up, shielded
water heaters may make a boiling noise; this is normal and does not indicate
any fault with the appliance.
To avoid the development of bacteria (legionella...) ensure that a temperature
of 60°C is reached every day. The thermostat is set at the factory at 65°C.
Maximum is 71°C.
User Maintenance
Operates once a month the PTR valve to prevent scaling and verify that it is
not blocked. If this is not done, damage may be caused and the guarantee
invalidated.
Maintenance by a qualified person
Remove the scale sludge. Do not scrape or chip at lime scale deposited on the
casing because this may damage the lining
Change the magnesium anode every 2 years or when its diameter is less than
10 mm. Changing the heating element or the anode requires the water
heater to be drained and the seal changed.
Draining the tank
Turn off the power and the supply of cold water, open the hot water faucets
and manipulate the safety valve before performing these operations. Refit
the heating element and tighten the screws gently (opposite screws in
sequence), check for leaks the next day and tighten if required.
If the supply cord is damaged, it must be replaced by a special cord or assembly
available from the manufacturer or approved service agent.
Replaceable parts
Replaceable parts are the thermostat, seals, heating element, boiler shell,
indicator light, magnesium anode and connection cable. The guarantee
requires genuine manufacturer's parts to be used.
