device must be inserted in the apposite connection bulb. The system, to be effective, must be able
to work and must have availability of cold water also in case of lack of AC power. The safety
devices must be accessible also after the installing for the maintenance and the functional verify.
The functional verify must be done regularly: we suggest at least once a year. The thermal
discharge circuit must not be used for the production of hot water for domestic use. On demand,
Rizzoli can provide a thermal discharge valve suited for its devices.

3.7 EXAMPLES
Here are some examples of possible system realization. These schemes are just valid as example
and must not be used in the making of the system. Ask always a thermal technician for an
installation that best suites your needs.
