Maintenance
DANGER: Risk of electric shock!
B Isolate the appliance from the power supply using the
fuse or another protective device before carrying out
any work on electrical parts.
10.1 General inspections
Inspect the appliance regularly to identify possible malfunctions.
B Keep the appliance's casing the installation location clean.
B Dust the system regularly using a damp cloth.
This way leaks can be identified and repaired at an early stage.
B Check all fittings for leaks on a regular basis.
10.2 Performance check
The temperature difference between the air inlet and the air outlet must
be 5 - 7 °C.
If the temperature difference is greater:
B Check the air inlet and air outlet ducts (wrong air flow rate)
If the temperature difference is smaller:
B Notify a contractor or customer service (the appliance must be tested
to improve its heating output).
10.3 Checking/replacing the magnesium anode
The appliance is protected against corrosion by an
internal magnesium anode.
NOTICE: Damage to the appliance!
The magnesium anode must be installed before
commissioning the appliance.
NOTICE: Damage to the appliance!
Check the magnesium anode annually and replace if
required. Appliances operated without this protection
are excluded from our warranty.
The internal wall of the DHW storage tank is coated with a double glass
lining. The coating is designed for normal quality water. When using
more corrosive water, the warranty only applies if additional safety
measures (f.i. dielectric joints) have been taken and the magnesium
anode is checked more frequently.
To check the protective anode:
B Isolate the appliance from the power supply.
B Remove front casing.
CAUTION: Risk of scalding!
B Before removing the magnesium anode, drain about
75 litres of water from the storage tank.
