SF2 ECCR OPERATION MANUAL
9.2 Cleaning the SF2
If another dive is planned, the SF2 can be reassembled. If the diving day is over,
however, the SF2 should be completely dismantled so that the individual
components can be cleaned and dried.
9. Unscrew the loop completely, rinse it and hang it up to dry.
10. Remove the scrubber and pack it in an airtight bag (labeled with the date and
dive time). When the standing time has expired, properly dispose of the used soda
lime and clean the soda lime container.
11. Remove the counterlung, wash it out and place it upside down to dry
12. Regularly disinfect the loop, top tube and middle section with counterlung.
9.3 Disinfect
The breathing circuit of the SF2 should be disinfected regularly in order to prevent
the components from becoming infected. About every 15-20 diving hours (in tropical
or warm regions every 10-15 hours) the breathing set, top tube, middle section and
counterlung should therefore be disinfected. EW-80 must be used for disinfection
according to the manufacturer's instructions. EW80 was specially developed for the
requirements of divers, but also fire brigades, police and military and is therefore
particularly suitable for the disinfection of rebreather devices.
