SF2 ECCR OPERATION MANUAL
9. After the dive
The correct procedure for dismantling and subsequent care is important so that you
can enjoy the SF2 for a long time and important components are not unnecessarily
damaged.
9.1 Disassembly of the SF2
1. Switch off the device, do not lie down, otherwise the saliva or water from the loop
will run into the head (oxygen sensors)!
2. Switch off the controller and the backup computer.
3. After diving in salt water, shower / rinse the entire device with fresh water,
preferably under pressure.
4. Unscrew the loop on the exhalation side and let it hang down so that saliva etc.
can drain off. Open the mouthpiece.
5. Close the bottles and vent them using MAVs and / or inflator. Disconnect the
oxygen solenoid valve connector.
6. Briefly release the tank from the lock so that the head lock can be opened.
7. Take off the head, remove the head cover and check whether the oxygen sensors
are moist. If the head is dry, the cover plate can be reinstalled. Tip: When removing
the head, pull on the oxygen valve connection and hold against the connection of the
MAV feed.
8. Remove the scrubber from the top tube and check whether the scrubber or the
upper carbon tube as well as the counterlung is damp / wet on the inside (it is best to
shine a lamp into it). If everything is dry and the service life has not yet expired, the
scrubber can be used again for a repetitive dive.
