Maintenance

Note
During the heat-up process, expansion water will drip
from the safety valve.
Notify your qualified contractor if water still drips after
the heat-up process has been completed.
f Regularly activate the safety valve to prevent it from becom- f
ing blocked, e.g. by limescale deposits. Open the safety valve
2 to 3 times. To do so, turn the bleed cap anti-clockwise.
Water should then drain into the tundish.
f Never use abrasive or corrosive cleaning agents. A damp f
cloth is sufficient for cleaning the appliance.
