Cressi Zen Octopus

Cressi Zen Octopus

The Cressi Zen Octopus gives your warm-water regulator setup a compact alternate second stage that is easy to identify. Its yellow body, large purge and simple Venturi lever help you find and handle the backup when needed.

Features and benefits

• Radial pressure openings. Openings around the front cover distribute water pressure across the diaphragm. This helps reduce unwanted valve activation from moving water, alongside the Venturi pre-dive setting.
• Dive/pre-dive control. The Venturi lever changes how the air stream assists inhalation. Use the pre-dive position during surface handling and while an alternate second stage is stowed, then the dive position when breathing from it, following the manual.
• Small second stage. The compact body reduces bulk at your mouth and is easy to pack. A large front purge button remains easy to find by touch.
• Visible alternate air source. Yellow detailing helps distinguish the octopus from the primary second stage. Secure it in an accessible position that suits your training and hose arrangement.

Setup and compatibility

Use this octopus with a compatible first stage in a manufacturer-approved regulator combination. Have the complete assembly checked and the hose routed for the alternate-air method you have been trained to use.

This combination is for water above 10°C. A cold-water second stage alone does not turn a warm-water first stage into a cold-water regulator system.

Care, rinsing and storage

Clean this component as part of a complete, correctly assembled regulator system. After each dive, connect the assembled regulator to a scuba cylinder and open the valve to pressurise the system. Keep it pressurised while fully submerging the first stage, second stages and connected hoses in fresh water. This allows thorough cleaning of the exposed components and hoses while helping prevent water entering the internal air passages, where it can cause corrosion and damage. Keep the cylinder secure throughout cleaning.

For routine cleaning, Dive Gear Australia recommends Cressi Neoclean Wetsuit Wash Neoprene Cleaner 500 mL or Revivex Wetsuit Shampoo 10 oz to help remove salt, chlorine and everyday residue. Dilute according to the cleaner’s label, then rinse thoroughly with fresh water.

Keep the regulator pressurised throughout washing and rinsing. Lift it out of the water and dry the first stage and cylinder connection before closing the cylinder valve, releasing the pressure and disconnecting. Fit the clean, dry dust cap, then allow the regulator to dry in the shade. Store it with the hoses loosely curved, without sharp bends or tension.

Before each dive, inspect the mouthpiece, hoses and connections for wear or damage. Have your regulator serviced by an authorised Cressi technician at the interval specified in its manual, or sooner if it leaks, is damaged or its breathing performance changes. Leave internal adjustments and repairs to a qualified technician.
