Installation instructions
Note
• Install the
line
pressure regulator in such a way that it is protected against mechanical
damage. Also note
that electricity must be kept separate from gas pipelines according to current
standards, see SIS HB 370.
• The installer must have the required product knowledge and
certificatin for shield gas brazing
and
have
undergone
brazing certification
in accordance with EN 13585 and EN 13134.
Brazing
must take
place
with shielding gas,
without flux and with silver phosphor copper
with a minimum of 5% silver content
,
article number QMT
7200812.
• The components of the
line
pressure regulator must not be exposed to temperatures
exceeding 100 ° C.
• The installer must ensure that the correct gas and function are achieved through safety testing and
that
the system complies with EN 7396-1 and national standard SIS HB 370.
• The system must be inspected for safety before commissioning in accordance with current
standards.
Warning
The use of shielding gas in medical gas systems must be carefully planned and separated from the
rest of the system. After
brazing
and testing is completed, the system is flushed with the medical gas
(= drug) to be contained in the system, to prevent personal injury. See SIS HB 370 and the hospital's
instructions.
The components of the
brazing
pressure regulator must not be exposed to temperatures exceeding
100 ° C, either during installation or operation. Should this happen or suspect that this has
happened, the
components
must be replaced and the system cleaned. In the event of fire, the
affected section must be separated and decontaminated immediately before operation. Sealing
plugs, packaging or protective packaging must not be removed until at the time of installation, as
there may be a risk of damaging or contaminating the product.

AIR for
driving surgical tools
, the
outlet pipe
from the
safety relief valves
must be
evacuated to the outside of
the
building according to EN 7396-1 and
SIS HB 370.

and (4b)
must be open.
When brazing
the outlet connection
(2),
shielding gas can be connected
through gas outlets (2a) or (2b).
NOTE!
Remember that valves (5a)
and (5b)
must be open.
When brazing
the outlet pipe (6) from
the
safety valve (3), shielding gas can
be
