Place of installation

The BOLLITORE 120 Lt appliance can be installed in all premises
permitted to appliances that are in conformity with the IP 40
degree of electrical protection.
3.5 Installation in older systems and systems
requiring modernisation
When the R BOLLITORE 120 Lt appliance is installed on old
systems or ones that need modernising, make sure that:
− Make sure that the system is fitted with safety and
control devices in accordance with applicable legislation
and standards
− Make sure that the central heating circuit has been flu-
shed out to remove all sludge and lime scale, and has
been vented and seal tested
− Make sure that a suitable water treatment system is ins-
talled if the quality of the supply/recirculation water so
demands. (Refer to the reference values listed in the
table alongside.)

Filters should be installed to eliminate impurities as this
extends the life of the storage cylinder and ensures the cor-

We recommend installing, in delivery and on the return line,
sectioning valves.
Connection to the Insieme EVOe 32 V LN boiler is done using the
specific KIT provided that the storage cylinder is beside the boi-
ler, to the right or to the left and away from the wall, at the back,
by at least 200 mm.
Positioning against the wall, at the back, or not next to the boi-
ler requires specific and/or in-wall hydraulic connections.

The domestic hot water system ABSOLUTELY MUST HAVE an ex-
pansion tank and a safety valve, and for this purpose the
"Expansion/safety kit" is available as an accessory.
