Test connector option
For testing at the test connection, we recommend the leak and function tester type DFP25
(Part no. 02 617 05).

START-UP

After ASSEMBLY and LEAK CHECK the product has been carried out successfully, it is
immediately ready for operation.
1. All shut-off fittings on the connected devices must be closed.
2. Slowly open the withdrawal valve or the gas cylinder valve.
3. Observe the assembly and operating instructions of the connected devices.
If you open the withdrawal valve or the gas cylinder valve too quickly, this can result in
a short-term pressure increase that triggers the overpressure shut-off device (OPSO).
If the visual indicator switches to RED during start up, do the following:
• Allow a few short bursts of gas to escape from the connected device to equalise the
pressure.
• If the pressure does not equalise and the OPSO cannot be unlocked
(visual indicator remains RED), the pressure regulator must be replaced.

OPERATION

The product requires no operation while it is running.

tighten the set screw again and check for leaks
again. See LEAK CHECK.
