Suunto Tank POD

6. Gases

6.1. Compressed air

Suunto Tank POD is recommended for use with compressed air. The compressed air supply
must comply with the quality of compressed air specified in the EU standard EN 12021:2014
(requirements for compressed gases for breathing apparatus).
WARNING: A Suunto Tank POD that has been used with compressed air must be
cleaned for oxygen service by a competent person before nitrox or oxygen use.
For further information about using the Suunto Tank POD with compressed air, see Product
Safety and Regulatory Information.

6.2. Enriched Air Nitrox

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.
WARNING: 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%.
WARNING: In nitrox use, the maximum operating depth and exposure time are
dependent on the oxygen content of the gas.
WARNING: 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.
WARNING: If the device is exposed to oil-contaminated breathing gas, contaminated
parts have to be re-cleaned by a competent person.
WARNING: There is a danger when using nitrox that contaminants may give rise to an
oxygen ignition.
