NewLife 5L and 10L Main Circuit Board Retrofit Instructions
This instruction is intended to guide technicians through replacing circuit board item
CB154 / CB160 (or older circuit boards) with circuit board CB200. Other modifications
will be required to install CB200 on previous design units, including updated wiring
harness, alarm buzzer, and O2 monitor board (for units originally equipped with the O2monitor option). There are two procedures listed below for you to upgrade the NewLife
with the 60601 compliant board. Procedure A specifies how to upgrade the board andcomponents with one LED light or non- oxygen monitor concentrators. Procedure B will
instruct the operator how to upgrade the concentrator to the current 60601 compliant
standard for the 3-LED oxygen monitor concentrators.

Procedure A:
1. Switch off the unit and disconnect the power cord.
2. Remove the side panels with the flat head screwdriver.
3. Disconnect the main power 10-pin connector from the circuit board. SeeFigure 1. Main Wire Harness
Note : If working on the NewLife 10L 230V unit, the 2-pin compressor connector willneed to be disconnected as well. This is located directly to the right of the main power
10-pin connector.

Figure 1. Main Wire Harness
4. Disconnect the alarm 6-pin connector from the circuit board. See Figure 2. Alarm WireHarness

5. Cut the tie-wrap at the circuit board pressure transducer and disconnect the green tube
from the transducer. See Figure 3. Pressure Transducer Zip Tie

Figure 3. Pressure Transducer Zip Tie

6. Push in on the circuit board support tabs while you lift each area of the circuit board toremove circuit board from the control panel. See Figure 4. Board Supports

7. Remove main wire harness and O2 wire harness from hour meter, terminal block, valve
block, EQ valve and fan board. Discard wire harness.
8. Remove and discard buzzer, 9 Volt battery, and 9 volt battery holder.
9. Remove and discard buzzer harness from the power switch.
10. Cut zip tie and move compressor capacitor out of the way to allow drilling of new alarmbuzzer mounting holes.
11. Install alarm buzzer AL022-1 with one mounting screw in location 1 (SC177-1). This screw
will be aligned with one of the existing holes used for the 9 Volt battery holder. See
Figure 5. Alarm Mounting Hole.

Figure 5. Alarm Mounting Hole
12. Drill a second mounting hole in the case with a 0.093” drill bit. See Figure 6.

Figure 6.
13. Install second alarm buzzer mounting screw SC177-1 in the new mounting hole that wasdrilled in step 12.
14. Re-attach the capacitor with a new zip tie, TW004-1.

NOTE: For non-oxygen monitor units, skip steps 15-22 and proceed to step 23. For
oxygen monitor units, complete steps 15-35.
15. Remove installed O2 monitor board and discard.
16. Hold EQ valve out of the way and drill two holes with a 0.093” drill bit for the O2 monitorboard (CB196-1). The holes should be 2.37 inches (6 cm) apart and inline with theexisting mounting holes. See Figure 7. New Board Mounting Holes

Figure 7. New Board Mounting Holes
17. Attach wire harness (WH107-1) to O2 board at J1C1. See Figure 8.

Figure 8.

Ref 21329212 Rev A

18. Install O2 board (CB196-1) onto superstructure with two screws (SC177-1) and two nylonspacers (HA006-1). Use ESD protection when handling boards. See Figure 9.

Figure 9.
19. Attach tubing to the O2 board. See Figure 10.

Figure 10.

Ref 21329212 Rev A

20. Install IL070-1 and retainer HA087-1 into the control panel O2 Monitor hole. Addretainer (HA087-1) bevel side opposite the front panel. See Figure 11.

Figure 11.
21. Install the top LED wire harness (WH145-2) only, the O2 monitor light, into the hole andtuck the other lights behind the control panel. The O2 monitor light will have red andpurple wiring. See Figure 12.
22. Add retainer HA087-1 (with the bevel side facing the front panel) onto the lens while
holding LED into the housing. Pressing the two HA087-1 retainers together will lock themin place. The beveled sides of both retainers should be facing each other. See Figure 12.

Figure 12.
23. Cut zip tie off the new harnesses WH147-1 and WH146-1. You will now have twoharnesses. See Figure 13.

Figure 13.

33. For non-oxygen monitor units only, attach the alarm LEDs to the main board, but leavethem tucked inside the front case panel (they are not needed to be installed in the frontcase panel if the unit was not orginaly equipped with the oxygen monitor feature).
34. Attach power switch jumper wire from the circuit breaker to the terminal block positive
top left. See Figure 21.

Figure 21.
35. Reattach case panels and test to ensure O2 monitor light works (if equipped) andpurity/flow is to specifications.

Procedure B
1. Follow instructions 1-19 from Procedure A.
2. Apply O2 label and instruction label (LA439-1 and LA190-1) to the front cabinet.
See Figure 22

Figure 22.
3. Drill additional holes for other LED lights.
4. Add retainers HA087-1 (with the bevel side facing the front panel) onto each lens while
holding LED into the housing. Pressing the two HA087-1 retainers together will lock themin place. The beveled sides of both retainers should be facing each other. See Figure 23

Figure 23.

Ref 21329212 Rev A

7. Apply heat shrink to the hour meter, circuit breaker and power switch.
8. Combine power switch and control board into one heat shrink. See Figure 25

Figure 25.
9. Ensure connections are correct and then use the heat gun to complete the heat shrink
starting closest to the cabinet then move backwards to the terminals. See Figure 26

10. Reattach the panels and test to ensure the top light illuminates for low O2, middle lightilluminates when there is a power failure, and the bottom light illuminates when there ishigh or low pressure. Also, ensure the purity/flow is to manufacturing specifications
before boxing. See Figure 27
