Annual replacement
Annual replacement
• Cressi-sub recommends complete regulator maintenance at least once a year, or more frequently in the case of particularly intense use.
• Maintenance must include replacement of all components provided in the annual equipment maintenance kit.
• The special tools for maintenance of this device are illustrated on one of next pages.
• Plastic, rubber and anodized aluminium parts can only be cleaned with hot soapy water using a soft bristled brush, taking care not to scratch or abrade
the rubber or plastic parts, especially on their pneumatical seal side. After they are cleaned, they should be immediately rinsed in clean, fresh water and
blown dry with low pressure breathing air, then check that there are no deficiencies, cracks orabrasions that do not allow the use”.
• Do not use acid or solvents or ultrasonic baths on rubber or plastic components.
• Metal parts must be washed with hot water and neutral detergent and rinsed in fresh water. Any concretions must be removed using ultrasound cleaning
or with diluted acid solutions, always followed by long and thorough rinsing under running water.
• Further information about cleaning procedure and/or repair phases of the equipment can be found in specific documents contained in the section
«Professional Area» located inside the site www.cressi.com.
• The new ORs must be greased with a thin layer of lubricant: this procedure reduces to a minimum the risk of damage during assembly.
• The metal threading can be lubricated with grease on the first two rings of threading.
