similarly qualified experts.
• Have the first heating cycle checked by an expert.
• Only a qualified expert may remove the electric cover
plate. Failure to follow this instruction can result in an
electric shock or other hazard.
• In order to guarantee safe operation, it is advised to
occasionally (approximately annually) have the correct
operation of the appliance and combined safety valve
checked by an expert. In addition, we recommend that
every two months the safety valve vent button should
be turned in the direction of the arrow in order to vent
the valve. By doing this it is possible to clean the valves
from any possible accretions (limescale, sand particles
etc.).
