No matter how many safety monitoring systems are in place, use your
own common sense and discipline to ensure you do not push the life
support systems beyond their designed limitations. It is your life being
supported - respect the equipment and its limitations.
OPTIONAL CARBON DIOXIDE SENSING MODULE
The EXPLORER is designed with an option to fit a CO
2
sensor. The user
can elect to buy this initially or upgrade to the sensor later.
Advantages to using a CO
2
sensor include:
1. To ensure active absorbent has been installed.
2. To ensure the absorbent sealing systems are functioning.
3. To warn of reducing absorbent efficiency in order to give the diver time
to respond by reducing depth, temperature or work rate to avoid an inci-
dent occurring.
4. To warn of rare situations when excessively high CO
2
levels may require
immediate bailout to safe open circuit gas.
See the Explorer CO
2
Sensor User Manual (doc. 12-4127 rev. 2 or newer)
for further details on safety and use of the Explorer CO
2
sensor.
!
NOTE: With the CO
2
sensor installed the system only requires a
1 minute pre-breathe. Without a CO
2
sensor installed a 5 minute
pre-breathe of the absorbent scrubber will be forced.
!
DANGER: Careful monitoring of scrubber duration is vital regard-
less of having a CO
2
sensor or not.
