2
O Cylinder Leak Test
1. Remove the N
2
O line pressure hose from the line pressure inlet on the AS3000.
2. Mount a full N
2
O cylinder to the rear panel yoke. If necessary, place a new clean tank
washer between the cylinder and the yoke to minimize any leaks at the yoke connection.
3. Open the N
2
O cylinder until its pressure gauge indicates cylinder pressure.
4. Close the N
2
O cylinder.
5. The N
2
O cylinder pressure gauge should not drop more than 10% of its initial pressure
over 1 minute.
6.8.5.2 O

Cylinder Leak Test
1. Remove the O
2
line pressure hose from the line pressure inlet on the AS3000.
2. Mount a full O
2
cylinder to the rear panel yoke. If necessary, place a new clean tank
washer between the cylinder and the yoke to minimize any leaks at the yoke connection.
3. Open the O

6.8.5.3 AIR Cylinder Leak Test
1. Remove the AIR line pressure hose from the line pressure inlet on the AS3000.
2. Mount a full AIR cylinder to the rear panel yoke. If necessary, place a new clean tank
washer between the cylinder and the yoke to minimize any leaks at the yoke connection.
3. Open the AIR cylinder until its pressure gauge indicates cylinder pressure.
4. Close the AIR cylinder.
5. The AIR cylinder pressure gauge should not drop more than 10% of its initial pressure
over 1 minute.
6.8.5.4 Line Supply Check Valves Test
1. Connect and open a full gas cylinder on each yoke.
2. Verify the cylinder gauges operate.
3. Remove each line pressure hose one at a time from the wall supply inlet.
4. Verify no gas is escaping from any of the three central supply high pressure hoses
connected to the AS3000 using a Digital Flow Meter.
5. Verify there is no external damage to the gas supply inlet coupling on the AS3000.
6. Reattach each central supply gas hose to the wall supply inlets.
