SECTION 26— SIEVE BED PRESSURE
CHECK
Pressure Testing
NOTE: For this procedure, refer to FIGURE 26.1 on page 80.
1. Connect pressure gauge to the ¼ x 2-inch silicone tubing with connector (p/n 1131392).
2. Remove plug in HomeFill port in back of concentrator.
3. Connect ¼ x 2-inch silicone tubing with connector to HomeFill port.
4. Check each connection to make sure it is tight.
5. Turn the concentrator On ( ).
NOTE: Adjust the concentrator to maximum rated Liter flow to 5 L/min. for 5 Liter and 9 L/min.
for 9 Liter.
NOTE: Wait approximately five minutes to allow system pressures to achieve proper equilibrium
before testing.
6. The pressure in the concentrator should rise within 20 seconds to 21 p.s.i.g. ± 0.3 and
for 5 Liter and 9 Liter shift the 4-way valve to the opposite sieve bed.
7. After the 4-way valve shift, the pressure in the concentrator will drop to 12 p.s.i.g. ± 2
before rising within 20 seconds to 21 p.s.i.g. ± 0.3 for 5 Liter and 9 Liter and shift the 4-
way valve to the opposite sieve bed.
8. If pressure reading is 21 p.s.i.g. ± 0.3 for 5 Liter and 9 Liter when both valve shifts are
made, proceed to STEP 10.
9. If pressure in the concentrator does not fall into the specifications listed above, refer
to Troubleshooting on page 16.
10. Turn the concentrator off
(O).
11. Disconnect pressure gauge from the HomeFill port and reinstall plug.
