Preparing for extended periods of disuse
If the storage cylinder is not going to be used for an extended
period of time, perform the following operations:
− deactivate the domestic hot water function on the boi-
ler combined with the storage cylinder (see the specific
chapter in the boiler's instruction booklet);
− close the water taps of the water system.

Empty the domestic hot water circuit and the heat exchan-
ger if there is a risk of frost (see section "Emptying")
Contact your local
R
Technical Assistance Service if you en-
counter any problems in completing the above procedure.

Cleaning
The only cleaning operations that need to be performed by the
user are those involving the external panels of the storage cylin-
der, which should be cleaned using just a cloth dampened with
soap and water.
In the case of stubborn marks, dip the cloth in a mixture of 50%
water and methylated spirits, or use specific products for this
purpose.
Once the cleaning is finished, carefully dry the storage cylinder.

to do this, turn the main system switch and that of the boi-
