SF2 ECCR OPERATION MANUAL
Users should monitor the displays, indicators and alarm systems and react
appropriately if the oxygen concentration becomes dangerous. The SF2 requires the
monitoring of an LCD display and should therefore only be used in waters with a
minimum visibility of at least 30 cm. Using the SF2 in conditions that do not allow the
LCD display to be monitored is at increased risk.
• The SF2 contains high pressure oxygen as one of its gas supplies and uses
equipment that has been specially cleaned and prepared to handle high pressure
oxygen. Accordingly, special care should be taken when handling these gas
mixtures, especially when refilling the gas bottles.
• For each component that comes into contact with high pressure oxygen (e.g.
regulator on the oxygen side and connected pneumatic parts), more appropriate
handling and cleanliness must be guaranteed. Components exposed to high
pressure oxygen must be serviced by a qualified service center. Failure to follow
these instructions could result in an oxygen fire and serious injury, including death.
• The SF2 requires proper assembly and important safety checks to be performed by
the diver prior to diving. Details on both points are contained in this manual.
• Using the SF2 without fully checking the system poses an increased risk for the
diver.
• Chapter nine of the manual describes post-dive care and cleaning and instructions
for long-term storage of the SF2. It also describes the shelf life of certain
components, various safety measures, and the maintenance and inspection
intervals. Failure to observe these instructions can damage individual components,
which in turn can lead to malfunctions of the SF2
• 8.4 The diluent bottle of the SF2 may only be filled with trimix or air. The helium
used must correspond to category 6.0. The oxygen cylinder may only be filled with
medical (breathable) oxygen of category 5.1. The SF2 may only be filled with
Divesorb soda lime.
• Any accessories used must be CE certified if they belong to the personal protective
equipment category. Additions and changes to the device by third parties are not
permitted.
• 8.5 The soda lime life of this device is 60 minutes under the following conditions:
diving depth 50 meters; Water temperature 4 ° Celsius, AMV 40 liters / minute.
