EUROPEAN STANDARDS

All TUSA regulators meet the European standard EN 250 - 2014 (Air).
(According Directive 89/686/CEE).
Certified for a maximum depth of 50 meters.
COLD WATER USE
Use of regulators in water temperature colder than 50 F / 10° C, requires
special equipment and precautions.
Only the "Cold type" (without >10°C marking) should be used in cold
water diving.
1. Make sure that your air supply meet the EN 12021 quality norm require-
ments.
2. Use a cylinder with a dual outlet Y-valve and two independent
breathing system outfitted for cold water use.
3. 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.
4. Do not purge the second stage outside the water to avoid freezing
incidence.
5. 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.
6. If the regulator were to freeze up accidentally and therefore free flow,
switch to your second breathing system and abort the dive.
