The DHW and heating circuits must be completed with expan-
sion vessels of adequate capacity and correctly-sized safety
valves. The discharge of the safety valves and appliances
must be connected to a suitable collection and disposal sys-
tem (see the price list catalogue for compatible accessories).
b
The selection and installation of the system components is
the responsibility of the installer, who must respect the stand-
ards of good practice and current legislation.
b
Special supply/make-up water must be conditioned using
suitable treatment systems.
a
It is forbidden to operate the boiler and circulators without
water.

On POWER EVO-X 50 DEP - 50 models, the diverting
valve (12) can be installed in the boiler .
