MAINTENANCE
PERIODIC CHECKS BY THE USER
• Check the pressure of the primary circuit pressure gauge: it should be between 0.5 and 1.5 bar.
• Visually inspect, on a regular basis, the valves, connections and accessories in order to detect
any leaks or malfunction.
• Periodically check the air bleed valve located on the tank top to ensure that it is not leaking.
• Check that the DHW water circuit safety valves are in good operating condition.
• In the event of a problem, please contact an engineer or your installer.
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.
The annual maintenance service, performed by an engineer, must include:
•
A check of the air bleed valve: the bleeding of air can lead to the need for adding water to
the system.
•
A check of the primary and DHW circuit pressure gauges.
•
The manual activation of the storage water circuit safety valve once a year. 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].
