conrming that the installation has been completed to the

highest standards in compliance with the instructions pro­vided by B in this instruction manual, and that it con­forms to all applicable laws and standards.

b

This product must only be used for the purpose for which
it is designed and made, as specied by B. B de-
clines all responsibility, contractual or other, for damage to
property or injury to persons or animals caused by improp­er installation, adjustment, maintenance or use.

b

The product must be serviced at least once a year. Servic­ing must be arranged in advance with the B Technical
Assistance Centre.

b

All servicing and repairs must be performed by a qualied

heating engineer.

b

If water leaks from the storage cylinder, turn off the water
supply and contact B’s Technical Assistance Centre

or a qualied heating engineer immediately.

b

If the product is not going to be used for an extended
period of time, contact the manufacturer’s Technical As­sistance Centre to have at least the following operations
performed:

- Close the shut-off cocks for the domestic hot water circuit

- Shut down the boiler connected to the storage cylinder
as instructed in its own manual

- Switch the storage cylinder OFF at the control panel (if

tted) and at the mains power switch

- Drain the central heating circuit and domestic hot water
circuit if there is any risk of freezing.

b

This instruction manual is an integral part of the product.
It must be kept safe and must ALWAYS accompany the
product, even if it is sold to another owner or transferred to
another user or to another installation. If you lose this man

­ual, order a replacement immediately. Keep the product
purchase documents to be presented to the B author­ised Technical Assistance Centre to request a service call
under warranty.

b

Size the solar expansion tank so as to ensure complete

absorption of the expansion of the uid contained within

the system, with reference to the prevailing regulations on

the matter. In particular, consider uid characteristics, con­siderable uctuation of service temperature and vapour

that might be generated during solar collector stagnation
stage. Proper size of expansion tank ensures setting off

of all volume changes of the heat transfer uid, avoiding

excessive pressure increase. Limited pressure changes
avoid reaching safety valve opening pressure and the con-

sequent uid drainage.
