Seac Sub N-Synchro Instructions page 19

You must use specific regulators certified for
such conditions and closely follow the instruc-
tions contained in the relevant handbooks.
Though the risks of freezing are limited as far
as possible by continuous research, it is not
possible to prevent a second stage freezing in
the most extreme conditions.
This could be the case when the water tem-
perature is below +4 degrees centigrade
and with external air temperatures is below
zero).
Consequently, in order to prevent or reduce
any possible risks, adequate training is need-
ed to prevent the regulator from freezing.
In extreme conditions you should strictly ob-
serve the following guidelines:
1. Do not use the regulator out of the wa-
ter particularly when the external surface
temperature is below zero.
2. Never actuate the second stage discharge
pushbutton unless under water.
3. limit as much as possible the time of rest
on the surface before diving.
4. Avoid actions or situations that may lead
to a rapid release of air from the second
stage.
