Step 3.
Open the box with the Oxygen and CO
2
sensors in it. Remove the sensors
from the box and open up the airtight bags.
DANGER: All sensors must be allowed to sit in an AIR atmo-
sphere for at least twelve hours prior to use in the EXPLORER.
The Sensors can be immediately assembled into the Sensor
Module but this module should not be fully installed for at least
12 hours after unsealing the sensors packages.
WARNING: After an initial calibration and dive the sensors
should be calibrated again after 24 hours.
Step 4.
Remove the LSS Module by turning the lock ring ½ turn counterclockwise.
Note the orientation in the Canister.
Visually
*
inspect the large sealing O-rings for damage (Fig. 2.2).
Pull the Sensor Module out from the Canister.
Remove the yellow and black CO
2
sensor filter cap as shown below (Fig.
2.3). This is a simple O-ring push fit and is retained in place once the Sen-
sor Module is assembled into the Canister, as are all the oxygen sensors.
Push the three oxygen sensors and one CO
2
sensor onto their respective
connection points as shown in the picture below.
NOTE: Ensure the oxygen sensors are installed with the white
membrane facing up, as shown.
Inspect the the yellow membrane in the CO
2
sensor cap to ensure it's flat in
the holder. Then replace the Sensor Module, and refit the cap (Fig. 2.4).

necessary to remove the O-ring before every dive.
