5. MAINTENANCE AND UPKEEP RULES

Magnesium anode
It is essential that the unit be inspected annually by the Technical Support Service (TSS) to eliminate lime scale
deposited on the heating element and check the condition of the magnesium anode (See point 6, page 40). If
the water in your area is very hard or corrosive you must ask for more frequent inspections.
If the magnesium anode is degraded, it must be replaced by the Technical Support Service.
Draining the unit
If installed in a location where freezing occurs, the unit must be drained if it is not going to used.
When this is necessary, drain the heater as follows:
- Unplug the heater from the mains electricity supply;
- Turn off the valve from the water mains;
- Open the hot water tap (basin, sink or bath);
- Open the drainage valve.
Periodic maintenance
After routine or special maintenance, we recommend you fill the tank with water and drain it off completely to
eliminate any residual impurities.
