Maintenance
Scheduled maintenance is essential for the safety, efficien-
cy and long working life of your combination storage cylinder.
Proper maintenance also reduces energy consumption and en-
sures reliability over time. Have your combination storage cylin-
der serviced either by the manufacturer’s Technical Assistance
Service or by a qualified heating engineer at least once a year.
Perform the following operations before beginning any main-
tenance:
− Switch the electricity supply to the storage cylinder’s
valve group and to any associated boiler OFF at the main
switch and at the control panel (if present)
− Close the shut-off cocks for the domestic hot water circuit
− Empty the combination storage cylinder.
