• Cressi-sub recommends a full maintenance of the regulator at least
once a year or more in case of particularly intensive use. The
maintenance must include the replacement of every OR, of the
conical filter and relating clip, of the first stadium HP pad and of the
seal.
• The required tools to carry out the maintenance are described in a
section of this manual.
• Wash the metal parts in warm water and soap, then rinse them in
fresh water. Remove any concretion by means of ultra-sound
cleaning or diluted acid solutions and rinse them carefully in fresh
water.
