Suunto Tank POD can be used with nitrox breathing gases (also known as oxy-nitrogen). Before using the product with nitrox breathing gases, it needs to be oxygen serviced.
If the side of your device is marked with text “EN 250 NITROX”, it has been tested according to EN 13949 standard and fulfills the requirements described in the standard. All the manufacturing materials of Suunto Tank POD and its sub-assemblies (for example, the compatible flow restrictors) are oxygen compatible and 100% oxygen adiabatic compression resistant.
Starting May 2021, all new Suunto Tank POD devices and their sub-assemblies have been cleaned for oxygen service in Suunto manufacturing. To mark this, the device has been sealed into a plastic bag and marked with text “Cleaned for oxygen service”.
If your device is not sealed into a plastic bag as described above, Suunto recommends you to treat it as not cleaned for oxygen service.
Suunto recommends that you do not use your device with nitrox gas mixtures before a trained and competent person has cleaned it for oxygen service.
Do not use nitrox gas mixtures if you do not have proper training. Appropriate training courses about nitrox and oxygen diving are essential prior to the use of this kind of equipment with oxygen content greater than 22%.
In nitrox use, the maximum operating depth and exposure time are dependent on the oxygen content of the gas.
If you use your Suunto Tank POD for nitrox diving, use it exclusively with nitrogen and oxygen, and no longer with air. Always keep your device clean for oxygen use.
If the device is exposed to oil-contaminated breathing gas, contaminated parts have to be re-cleaned by a competent person.
There is a danger when using nitrox that contaminants may give rise to an oxygen ignition.
The use of breathable air according to EN 12021 may contaminate the diving apparatus. Do not use the device with nitrox or oxygen before it has been cleaned for oxygen service by a competent person.
Suunto Tank POD devices manufactured before May 2021 have not been cleaned for oxygen service by Suunto.
Open the plastic bag only when you start using your Suunto Tank POD. This way the possible contamination is minimized.
If you use Suunto Tank POD with gases with oxygen content greater than 22%, you need to keep it clean and avoid any kind of contamination which may give rise to an oxygen ignition during the use, handling, and storage.
To minimize the risk of oxygen ignition, always open the pressure valve(s) slowly.
If you are using additional high pressure accessories connected to the Suunto Tank POD and you are using nitrox breathing gas mixtures (with oxygen content greater than 22%), make sure they are approved for this purpose and are compliant to EN 250 and EN 13949. Suunto official high pressure hose accessories are tested according to EN 250 and EN 13949 standards.
