1.2 Removing existing parts

Sensor M3 fixing nuts

1. Power down the Incubator and completely disconnect from the Mains/Power Supply. Open the outer and Inner Door (option on 48 R) then remove the white porous cover on the CO2 Sensor from inside the chamber of the incubator (dashed red circle in image below).

2. Rear cover removal:

170 R – Remove the rear access panel by unplugging the access port plug and then

unscrewing the 8 x Pozidriv head screws with washers (see all screws and plug in dashed red circles in image below).

NOTE: Protect top face of equipment tray with tape.

48 R – Remove the CO

with washers (see all screws in dashed red circles in image below).

3. With the access panel removed, locate the insulation block covering the CO2 Sensor and carefully remove the block (shown in yellow dashed boxes in images below) and place to one side for refitting later. The rear of the CO

Sensor will now be visible.

4. Remove the existing CO unplug the Auto-Zero port tubing leading from the pump (see dashed yellow circles on image to the left below). Unscrew the 3 x M3 securing nuts and washers, and place to the side for refitting (only one nylon washer will be reused).

5. Equipment Tray and 48 R Top Cover:

170 R – Open the rear equipment tray by unscrewing the 2 x large Pozidriv head screws as shown, reference top left-hand image on page 6 and then remove the cover plate shown arrowed on top right-hand image page 6 by unscrewing the 4 x Pozidriv head screws. Discard the old plate after removal. Save screws for further use.

Carefully snip zip ties.

Secure top cover as shown.

Re-secure top cover when complete.

NOTE: Now procede to step 7 for 48 R.

6. On the 170 R locate the Auto-Zero Pump and disconnect the tubing leading to the CO Sensor from the Auto-Zero Pump (see “Pump Out” in diagram below). The tubing is fixed to the pump barbs using cable zip ties. Trace the tubing back to where it enters the Cover Plate access hole area and cut the tubing back to this point using the side cutters; a new length of tubing will be fitted later.

7. Existing Expansion PCB removal:

170 R – Using the diagram below with points highlighted in yellow:

1. Disconnect the 40 way Ribbon cable to Board 2 Expansion PCB.

2. Remove the 3 mm Nut securing the Earth tag to the Tray.

3. Unscrew the 2 x RS232 Hex head fixing posts.

4. Disconnect the wiring for the Live In and the Base Element Live Out as well as the wiring

for any other options fitted. Take note of locations if unsure as this will help to reconnect the replacement Expansion PCB.

5. Remove the 4 x Pozidriv Head Securing Screws.

48 R – Using the diagram below with points highlighted in yellow:

1. Disconnect the 40 way Ribbon cable to Board 2 Expansion PCB.

2. Unscrew the 2 x RS232 Hex head fixing posts.

3. Disconnect the wiring for any options fitted. Take note of locations if unsure as this will

help to reconnect the replacement Expansion PCB.

4. Lift up carefully from the PCB Support Pillars.

8. Solenoid Valve fitting:

170 R - Mount the Solenoid Valve to the new cover plate using the fixings supplied and fit the

new cover plate in the position shown in the image below using the 4 x Pozidriv head screws which were kept aside earlier. Route the Red/Black wires from the Solenoid Valve along existing cable route to the Expansion PCB, secure with zip ties. The tubing will be connected when fitting the new CO2 Sensor.

48 R – Fit the 48 R Solenoid Valve mounting bracket with self adhesive backing to the equipment tray in the position shown in the image below.

Screw Valve to bracket using screws supplied and route the Red/Black wiring for the Pump back to the expansion PCB area. The tubing will be connected when fitting the new CO Sensor.

9. Cable zip tie all wires in place to secure to tray.

10. Replacement Expansion PCB fitting:

170 R - Refitting is a reversal of removal. Follow the wiring diagram and image below.

11. 170 R CO2 Sensor fitting

Unpack the new CO2 Sensor and fix in place with the bracket supplied and the original nuts and washers and new spring washers but only reuse one of the original nylon washers in the location shown in the image below. Fit the spring washers Tighten the M3 fixing nuts to 0.4 Nm (Newton meters).

13. Route the tube from the Auto-Zero Pump “Out” (see Pump diagram at the bottom of Page 7) to the bottom barb of the Solenoid Valve shown in the image above.

NOTE: Air flow must follow the direction of flow arrows on Auto-Zero Pump and CO Valve.

in direction shown. If the elbow becomes loose, the integrity of the CO compromised.

14. Cut the old Pump tubing in line with the glass fiber insulation and trim the CO harness in line with the glass fibre insulation and strip and twist 7 mm from the end.

15. Connect the existing wiring harness to the CO and right-hand image, page 13). Ensure you have stripped 7 mm of insulation from the existing harness wires and twisted the strands before connecting them.

NOTE: Green on the existing harness connects to Brown on the new CO2 Sensor assembly harness.
