CYLINDER CHANGE
When changing cylinders with toxic or corrosive gases the necessary personal safety measures must
be taken (respiratory protection, eye protection and protective clothing.) Observe the MAK values (see
Technical norms for dangerous substances, TGRS 900) and have the correct respiratory protection filters
at hand.
Did you use corrosive or toxic gases, you have to purge the pressure device with inert gas (see chapter
6.2 "External gas purging"). This will ensure that the remaining dangerous gas will be purged completely.
PREPARATION
Tightly close the shut-off valve on the gas cylinder. Close the inlet valve.
1.
Open the outlet pressure valve, if there is any. Empty the pressure regulator completely by turning the
2.
handwheel clockwise. The indicators on the inlet and outlet pressure gauges must both be all the way
on „0".
Turn the handwheel of the regulator counter-clockwise as far as possible (valve gate closed).
3.
Close the process gas valve.
4.
CYLINDER CHANGE
Using cylinder pressure regulator FMD 500/502-21, you have to purge at first. Loosen the union nut on the
gas cylinder using a spanner. Control the threats. Change the seal. Connect the new cylinder following the
steps above (see chapter 6.2). Make a leakage test (following the steps above).
9 .
TAKING OUT OF OPERATION
Release the pressure on pressure controller and lines by directing the gas to the consumer. The indicators
on the inlet and outlet pressure gauges must be all the way on „0". With corrosive or toxic gases, purge all
components with inert gas. The necessary personal safety measures must be taken (respiratory protection,
eye protection and protective clothing.) Observe the MAK values (see Technical norms for dangerous
substances, TGRS 900) and have the correct respiratory protection filters at hand.
9.1. CYLINDER PRESSURE REGULATORS
For a brief interruption of gas removal it is sufficient to close the shut-off valve on the regulator. For a longer
interruption the regulator must be released from pressure by turning the handwheel counter-clockwise.
Close the cylinder valve as a safety precaution.
9.2. SUPPLY PRESSURE REGULATORS
Close the preliminary shut-off valve.
9.3. LINE PRESSURE REGULATORS
Close the pressure regulator by turning counter-clockwise.

SERVICING AND MALFUNCTIONS

10.1. MAINTENANCE
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.
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 informa-
tion in chapter two.
10.2. MALFUNCTIONS
These pressure regulators are extremely reliable. If, however, the outlet pressure should rise excessively and/
or the relief valve triggers, please close the gas supply and contact the manufacturer.
1 1.
REDELIVERY OF PRESSURE DEVICE
There are only pressure device accepted for redelivery, which are completely cleaned of any fluids and
purged with inert gas. The packaging has to be closed gas tight.
Please take care to the German Danger Goods Regulation GefStoffV and the Danger Goods Regulation-
Transport as well to national laws and regulations..
+
Please enclose to each redelivery a carefully and completely fulfilled redelivery formular (see back cover).
