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.

48 R – Remove the Top Cover by unscrewing the 4 x large Pozidriv head screws. Pull the Top
Cover forward and lift upwards. The wiring harness to the LCD and Keypad is not long
enough to place the top cover at the side of the Incubator.

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.

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.

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.
