SF2 ECCR OPERATION MANUAL
9.4 Transport and storage
For the transport of the SF2 e.g. In the car, the oxygen and diluent tanks must be
removed and transported separately. Otherwise, the tank brackets on the SF2 could
be damaged due to vibrations or lever forces while driving.
The SF2 should be stored in a dry, shady and well-ventilated place. Avoid
unnecessary UV or solar radiation and high temperatures.
Remove the soda lime, clean all parts of the SF2 and grease the O-rings. Disinfect
the components of the breathing circuit and do not store the loop hanging.
For longer storage times, all batteries (oxygen solenoid valve and controller) and the
oxygen sensors should be removed. Broken batteries or oxygen sensors can leak
and corrode the contacts or connections.
10. Maintenance
The SF2 is a very robust and low-maintenance rebreather, but it should still be
handled with care and regularly serviced. In general, all components must be visually
checked regularly and cleaned and cared for accordingly.
In order not to impair the function of the SF2, certain components must be serviced
or replaced at regular intervals.
The following maintenance work may be carried out by the user:
Replace the O-rings, the flutter valves, the oxygen sensors and the batteries.
All work on the electronics, the oxygen solenoid valve, the first stages and the
body may only be carried out by the manufacturer or an authorized service
center.
Regardless of the specified maintenance intervals, used or defective components
must be replaced immediately. Use only original spare parts. If other parts are used,
the guarantee is void. In addition, there is a risk that malfunctions due to incorrect
spare parts could lead to life-threatening incidents or death.
NOTE
The SF2 has to be qualified every 12 months
and maintained by a workshop authorized by the
manufacturer.
