question is suitable for the intended use
(gas, pressure, material, etc.)
Before switching on the pressure device
ensure that no-one can be put in a situation
of danger by starting up the pressure
device.
If required, carry out internal gas purging (see chapter 5.3) or
external gas purging (see chapter 5.4) with subsequent internal
gas purging (see chapter 5.3) before starting up and filling the
subsequent lines. Please remove all closing caps.
1. Check that purging lines, exhaust lines (from safety reasons
strictly recommended) and spiral are connected correctly.
2. Close all valves of the fitting (handle at right angles to pipe).
3. Turn the handwheel of the pressure regulator (3) as far as
possible anticlockwise - through passage is thus closed.
4. Open cylinder valve (1) slowly.
5. Open the process gas inlet valve (11) slowly! (if present).
6. Set the required outlet pressure by turning the handwheel
on the pressure regulator (3) clockwise.
7. Open the process gas outlet valve (6) - if present -
slowly! (especially in the case, that subsequent large tube
volumes are connected).
6. CHANGING CYLINDERS AND ENDING
OPERATION
1. Close the cylinder valve (1) at the gas cylinder.
2. Close the process gas outlet valve (6) and/or inlet valve
(11) - if present.
3. With toxic, corrosive or pyrophoric gases, carry out
external gas purging (see chapter 5.4).
4. Remove connection spiral (2) from cylinder
valve (1).
5. If a dry filter is used, replace the filter element every
time a cylinder is changed (see separate instructions).
6. Connect new process gas cylinder.
(see chapter 5.2.2).
7. Before restarting operation with the fitting, if necessary
carry out internal gas purging (see chapter 5.3) or external
gas purging (see chapter 5.4) with subsequent internal gas
purging (see chapter 5.3).
6.2 Ending operation
For brief interruptions in gas removal it is sufficient to
With corrosive or toxic gases, purge all
components with inert gas (see chapter 5.4
“External gas purging”.
6.1 Changing cylinders
Appropriate measures for personal
protection must be taken when changing
bottles with toxic, corrosive gases
(respiratory equipment, eye protection,
protective clothing).
+
Observe MAK values (see technical rules for
hazardous substances, TRGS 900), have
correct respiratory equipment filters ready.
If toxic or corrosive gases were taken out
of the gas cylinder, the system must be
purged with inert gas before the empty
bottles are changed (see chapter 5.4
“External gas purging”). This ensures that
any residual gas in the line is safely
disposed of via the exhaust line.
close the process gas outlet valve (6). Only closing the
pressure regulator (3) is not sufficient to prevent leaks as
gas emission can occur through the hoses or the connected
consumers. For longer interruptions the pressure regulator
(3) must be depressurized by turning the handwheel
anticlockwise.
For reasons of safety, always close the
cylinder valve.
7. SERVICING AND MALFUNCTIONS
7.1 Servicing
For reasons of safety, repairs and servicing
must only be carried out by the
manufacturer or by a specialist firm
authorized by the manufacturer, and only
using original spare parts.
Observe the special operating instructions
for stations with dry filters.
A pressure test must be carried out once
annually on flexible hose lines to check for
leaks. The lines must be replaced if
necessary.
To ensure perfect function and consistent safety, all
components of the fittings of a gas supply system should be
checked once annually by the manufacturer. A service
contract is recommended for this purpose.
Please note the Guarantee and Delivery Conditions of the
manufacturer as well as the fundamental safety information
in chapter two.
7.2 Malfunctions
These ressure regulators are extremely reliable. If,
however, the outlet pressure should rise excessively and/or
the relief valve triggers, please contact the manufacturer.
