Risk of injury due to hazardous fluid residues!
Hazardous fluid residues may cause severe injury or death.
Use a vessel to collect any hazardous fluid residues and dispose of them properly.

2.
Remove the drain plug to drain fluid residues.
3.
After draining properly, dispose of the fluid residues that have been collected.

Screw the drain plug to the upper part of the ball valve body.
Draining is now complete.
8.6
Draining the Argus Ball Valve with the Safety Plug (if present)
The safety plug, also called the “captive drain plug” is designed to prevent unintended loss
of the drain plug when draining fluid residues. The safety plug can also be closed again
immediately when loosening – even if there is overpressure in the Argus Ball Valve.
Note that the operation and use of the safety plug may vary depending on the type
and manufacturer. Consequently, the following instructions are intended to illustrate
the use only as an example. Information on the exact operation and use of the
safety plug can be found in the manufacturer's documentation.
