DIVING IN COLD WATER

Unscrew the knob positioned on the yokeor, in case of Thread connection system, unscrew the threaded ring nut. Incorrect preparation for cold water diving (less than +10 degrees centigrade) might cause serious damage. Before diving in cold water, you should followspecific training under the supervision of spe- cialized and qualified trainers in cold water diving.You must use specific regulators certified forsuch conditions and closely follow the instruc- tions contained in the relevant handbooks.Though the risks of freezing are limited as faras 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 reduceany 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. Lay the cylinder down to prevent it fromfalling, positioning it in such a way that it cannot roll in any direction. Thoroughly clean and dry the first stagefilter and housing with a cloth or with a soft compressed-air jet. Repeat the same operation on the protec-tion cap covering the filter.
ENGLISH Place the protection cap onto the filterand 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 inrunning 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 placesheltered 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 divingseason 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.
