WARNING
UNDER NO CIRCUMSTANCES SHOULD ANY OTHER
CONNECTIONS OR OUTLETS/INLETS BE USED FOR ANY OTHER
EQUIPMENT OR SERVICES.
1. Connect a suitable argon supply at a regulated input of 0.3bar (4psi) to the quick
connect Argon gas connector on the rear panel (see Figure 2-1.
2. Connect a suitable nitrogen supply at a regulated input of 0.3bar (4psi) to the
quick connect Nitrogen connector on the rear panel. We do NOT recommend
using air as the purge gas.
If you prefer, you can use argon for both process and purge supplies. To do so, install a
'T' piece across both gas inlets.
Connectors are push-fit and will 'snap' into a locked position. To release a connector,
depress the metal tongue.
