Adjusting Regulator - Invacare Platinum IRC5LXO2AW Service Manual

SECTION 11—REGULATOR

Adjusting Regulator

1. Turn unit on .
( )
2. Install pressure gauge onto oxygen outlet.
NOTE: Check O pressure at oxygen outlet. It should read a steady 34.5 ± 3.45 kPa (5 ± 0.5 psi)
2
for 5 Liter; 62.05 kPa ± 3.45 kPa (9 ± 0.5 psi) for 9 Liter. If pressure is not in specification, proceed
to STEP 3. If pressure falls within specification, no adjustment is needed.
3. Turn power Off (O) and unplug the unit.
4. Remove cabinet. Refer to Removing Cabinet on page 25.
5. Plug unit in and turn power switch on
6. Examine the regulator and FIGURE 11.1 on page 45 to determine what type of
regulator is installed.
7. Perform one of the following:
A. 5 Liter models with Regulators before 07/01/12 - Insert a 5/32-inch Allen wrench
into the pressure adjustment screw.
B. 9 Liter models with Regulators before 07/01/12 - Locate the pressure adjustment
knob.
C. All models with Regulators after 06/30/12 - Insert a 3/32 (2.5 mm) Allen wrench
into the pressure adjustment screw.
8. While reading pressure gauge, do one of the following:
• Turn pressure adjustment screw or adjustment knob, clockwise to increase output
pressure or,
• Turn pressure adjustment screw or adjustment knob, counterclockwise to decrease
output pressure.
9. Adjust until pressure reads:
• For 5 Liter models: a steady 34.4 kPa ± 3.45 kPa (5 psi ± 0.5 psi).
• For 9 Liter models: a steady 62.05 kPa ± 3.45 kPa (9 psi ± 0.5 psi)
10. Allow concentrator to run for ten minutes.
11. Retest the pressure by performing STEPS 8-10, to ensure proper operation.
12. Once required pressure is achieved, reinstall cabinet. Refer to Removing Cabinet on
page 25.
13. Refer to Troubleshooting on page 20 if you are unable to adjust or maintain 34.4 kPa
± 3.5 kPa (5 psi ± 0.5 psi) for 5 Liter model and 62.05 kPa ± 3.45 kPa (9 psi ± 0.5 psi) for
9 Liter model.
