ge through the first stage shall pass throu-
gh a 0.20 dia. hole.
Unscrew the knob positioned on the yoke
or, in case of Thread connection system,
unscrew the threaded ring nut.
Lay the cylinder down to prevent it from
falling, positioning it in such a way that it
cannot roll in any direction.
Thoroughly clean and dry the first stage
filter and housing with a cloth or with a
soft compressed-air jet.
Repeat the same operation on the protec-
tion cap covering the filter.
Place the protection cap onto the filter
and fasten it by tightening the knob screw
or, in case of thread connection, screw up
the swivel-screw cap.
Rinse but do not immerse the regulator in
running fresh water taking care of all its
parts.
In this phase do not for any reason remo-
ve the first stage filter protection cap. Du-
ring this operation be extremely careful
not to press on the diaphragm, to avoid
water leaks into the first and second stage.
If you think you are not going to use the reg-
ulator for some weeks, again connect the reg-
ulator to a cylinder and, by depressing the
second stage pushbutton, cause continuous
delivery for about ten seconds. In this way all
the water is discharged and there is no risk of
scale deposits or evil taste.
The regulator shall be put to dry in a place
sheltered from the sun and dust, hanging
from the first stage yoke, so that the hose is
not bent.
At the end of a particularly intensive diving
season or, in any case, after a long period of in-
activity, it is advisable to give the equipment to
an authorized service centre for a complete
overhaul. Consequently, we advise you to con-
tact your dealer who will give you the best in-
formation on the quickest and safest ways for
carrying out the annual overhaul.
DIVING IN COLD WATER
Incorrect preparation for cold water diving
(less than +10 degrees centigrade) might
cause serious damage.
Before diving in cold water, you should follow
specific training under the supervision of spe-
cialized and qualified trainers in cold water
diving.
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 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 water
particularly when the external surface tem-
perature is below zero.
2. Never actuate the second stage discharge
pushbutton unless under water.
3. Try to limit as far as possible the time of rest
on the surface before diving.
