the leak has been rectified. Make sure that the pressure lines are
tightly connected to the APC device. The same applies when con-
necting the pressure reducer to the argon gas cylinder.
3.2 Using argon
Argon is heavier than air. If it accumulates in the air that is
breathed in, oxygen may be displaced – without any obvious in-
dication – resulting in a risk of suffocation. Symptoms of oxygen
deficiency include drowsiness, rise in blood pressure, and respi-
ratory distress. In an atmosphere of pure argon, a person would
fall unconscious immediately without prior warning and suffo-
cate!
The APC device may only be operated with argon. It is possible
to connect gas cylinders with hazardous contents to the cylinder
connectors of the device. For this reason, you must verify wheth-
er the gas cylinders do indeed contain argon (i.e. appropriate
color code on the argon gas cylinder / cylinder jacket, label with
product name). Labels must not be damaged or removed.
3.3 Using the pressure reducer
Do not use oil or grease.
Never fiddle with the screw of the pressure reducer as long as
the regulator is under pressure! Gas can escape abruptly or
cause the pressure reducer to be ejected in explosive fashion.
Never apply pressure to the pressure reducer in the reverse di-
rection (i.e. on the output side), as this can contaminate and
damage the APC device.
