nicians, exclusively with the use
of original spare parts. Failure to
comply with the above instruc-
tions may compromise the safety
of the equipment and relieves the
manufacturer of any responsibili-
ty for the consequences.
For the correct operation of the
device, the inlet water pressure
must be:
ATTENTION
- maximum 0.7 MPa (7 bar);
- minimum 0.15 MPa (1.5 bar).
• Water may drip from the safe-
ty valve discharge pipe; leave
this pipe open to the atmos-
ATTENTION
phere.
• The safety valve must be op-
erated regularly to remove
limescale deposits and to
check that it is not blocked.
• Connect a rubber pipe to the
condensate drain, taking care
not to force too much so as
not to break the drain pipe
and refer to par. "6.7.1 Con-
densate drain connection" on
page 153.

This safety device must not be
tampered with and must be ope-
rated frequently to check that
it is not blocked and to remove
any limescale deposits. Water
may drip from the pressure relief
outlet pipe and the pipe should
be left open to atmosphere. The
discharge pipe connected to the
pressure relief device must be in-
stalled in a constantly downward
direction and in an environment
free from the formation of ice.
The use of a pressure reducer
(not supplied) is required if the in-
coming water pressure is greater
than 0.7 MPa (7 bar), and this must
be connected to the water mains.
The discharge pipe of the sa-
fety valve must be installed
downwards and in an envi-
ronment not subject to freezing.
For correct operation of the
