BASELINE
®
cylinder and secondary pressure regulators
9. Shutting down operations.
9.1 Cylinder regulator
For short stops in extraction of gas it is sufficient to close the shut-off valve on the regulator. In the case of longer stops, the regulator has
to have the pressure released by turning the hand-wheel anti-clockwise. For safety reasons close the cylinder valve.
Caution
When dismantling as a general rule note: release pressure from regulator and tubing by venting the gas in a
safe manner, the pointers of the inlet and outlet pressure gauges must indicate no internal pressure.
10. Maintenance and breakdowns.
10.1 Maintenance
The pressure control device should be examined regularly to make sure
it is working correctly and to check for leaks. Prior to carrying out main-
tenance and service work, inform the operating personnel and the users.
For all service and maintenance work, shutoff and secure all power to
associated operating equipment and secure the main switch to prevent it
from being turned back on. Check fittings, which have come undone for
correct positioning. After completing maintenance work, make sure that
all safety devices and installations are functional.
Danger
For safety reasons, repairs and or maintenance
work to the BASELINE

pressure equipment,
should only be carried out by BOC service compa-
nies or their authorized service personnel.
10.2 Malfunctions
By experience these regulators have a high level of reliabil-
ity. Should any of the following breakdowns occur despite
this, exchange the regulator and have the defective equip-
ment repaired:
– Gas release at the outlet of the regulator when the hand-
wheel is completely closed.
– Display of increasing pressure on the outlet pressure gauge
when the valve is closed or no gas is flowing.
– Gas release at the regulator cover.
– Gas release at a gasket.
– Too high pressure drop with normal flow.
– Gas release at the pressure relief valve.
– Gas release at the pressure gauge.
– Pointer of a pressure gauge does not return to „0“.
– Faulty pressure display.
11. Return of pressure equipment.
Danger
Pressure equipment can only be returned with
prior authorization. It must be completely de-
pressurized, drained and purged with an inert
gas. The packaging must be sealed gas-tight
to prevent contamination or exposure during
transport.
Danger
Pay attention to local rules and legislation with regards to
transport and storage of hazardous goods and materials.
