Installation Process
Recalibrating
an Antaris EX-Z2
This procedure should be run after the purge system is replaced, when the
purge system is not working properly, or when the customer requires it.
You must clear supply line of debris and condensation and confirm that the
relief valve, alarm/pressurized and purging indicators, and pressure loss
alarm are operating correctly. You will need the following tools for these
procedures:
•
flat-blade screwdriver
•
4 mm OD nylon tubing
•
a pressure gauge or water manometer
•
stop watch or other timing device
•
pencil or other marker
Clearing the purge supply line
To remove debris and condensation from the purge gas supply line:
1.
Disconnect the supply line from the inlet to the purge system.
2.
Blow clean, dried air or nitrogen through the supply line for at least
15 seconds per meter (3 feet) of supply pipe length.
This removes any debris or condensation.
3.
Connect a pressure gauge and confirm that the supply line pressure
being delivered to the enclosure inlet is between 4 barg and 8 barg,
60 psi and 115 psi, or 400 kPA and 800 kPA.
4.
Turn off the purge gas and reconnect the supply line to the
MiniPurge inlet.
