ENGLISH
Cold water use
WARNING: Use of regulators in water temperature colder than 50
°F / 10°C, requires special equipment and precautions.
Only the Polaris should be used in cold water diving.
- Make sure that your air supply meet the EN 12021 quality norm
requirements.
- Use a cylinder with a dual outlet Y-valve and two independent breathing
system outfitted for cold water use.
- Do not expose the regulator to cold air (colder than 32°F / 10°C). Place
the regulator first stage in the cold water to bring its temperature up
before use.
- Do not purge the second stage outside the water to avoid freezing
incidence.
- During the dive: do not purge unnecessary demands on your regulator,
i.e. avoid using all at once the regulator, the octopus, the BC power
inflator and the dry-suit valve. Do not purge the regulator unless
required.
- If the regulator were to freeze up accidentally and therefore free flow,
switch to your second breathing system and abort the dive.
WARNING: Cold water diving requires special equipment
and training. Failure to follow the above instructions and
recommendations can result in serious injury or death. Certified
instruction should be received and completed for cold water and
ice diving from a certified instructor by a recognized training
agency prior to attempting any cold water or ice diving.
