ANNUAL MAINTENANCE
Essential instructions for the correct operation of the appliance
• The discharge pipe of the safety unit must be open to the outside. If the
safety unit drips periodically, it may be due to an expansion problem or
clogging of the valve.
• For internal inspections, the hand hole can be used. If there is none,
use one of the water connections to insert the appropriate inspection
equipment. If necessary, drain the tank before inspection.
Essential instruction for the electrical safety
• Shut down external electrical supply of the appliance before performing
any operation on the electrical circuit.
Annual maintenance tasks, performed by an approved installer, must include:
•
The manual activation of the DHW circuit safety valve. This operation will lead
to a discharge of hot water.
•
A check of the correct operation of valves, taps, control units and accessories
that are possibly installed [refer to the manufacturer's instructions if necessary].
•
Check of the scaling and anode condition (See opposite page).
