3. Setup and Installation
Proper setup of your G260 second stage is crucial for safe diving. Always ensure connections are secure and free from leaks.
Attaching to a First Stage Regulator
- Identify the low-pressure (LP) port on your first stage regulator. The G260 comes with a standard 3/8" threaded low-pressure hose.
- Carefully screw the hose connector of the G260 second stage into the designated LP port on your first stage.
- Hand-tighten the connection firmly. Do not overtighten, as this can damage the O-rings or threads.
- Perform a leak check by pressurizing the system and listening for any hissing sounds. If a leak is detected, re-check the connection or consult a professional.
Hose Routing (Left-Right Option)
The G260 offers a left-right hose attachment option, which is particularly useful for technical diving configurations. Consult your dive instructor or an authorized Scubapro dealer for guidance on optimal hose routing for your specific diving style and setup.
4. Operation
Understanding the operational features of your G260 will enhance your diving experience.
Pre-Dive Check
- Before each dive, ensure the regulator is securely attached to the first stage and the tank valve is open.
- Take a few breaths from the second stage to confirm proper airflow.
- Depress the purge button to ensure it functions correctly and clears water effectively.
- Check for any signs of free flow or excessive breathing resistance.
Adjusting Inhalation Effort
The G260 features a diver-adjustable inhalation effort knob, typically located on the side of the regulator. Turning this knob allows you to fine-tune the breathing resistance to your preference. Turn clockwise for increased resistance (firmer breath) and counter-clockwise for decreased resistance (easier breath). Adjust this on the surface or during a controlled descent to find your comfortable setting.
Venturi Initiated Vacuum Assist (VIVA)
The VIVA switch, usually a lever or knob, controls the Venturi effect within the regulator. In the "pre-dive" or "min" position, it helps prevent free flow when the regulator is out of your mouth or in strong currents. In the "dive" or "max" position, it provides maximum airflow and reduced breathing effort during the dive. Always switch to "pre-dive" before entering the water or when the regulator is not in use.
Purge Button
The large front purge button allows you to clear water from the regulator. Press it firmly to activate a strong purge. A gentle press can be used for minor clearing or to test airflow.
5. Maintenance and Care
Proper maintenance extends the life of your regulator and ensures its reliability.
After Each Dive
- Rinse Thoroughly: With the regulator still attached to a pressurized first stage (or with the dust cap securely in place if detached), rinse the entire second stage with fresh, clean water. Do not press the purge button while rinsing unless the regulator is pressurized, as this can allow water to enter the hose.
- Dry: Allow the regulator to air dry completely in a shaded, well-ventilated area. Avoid direct sunlight.
- Inspect: Visually inspect the mouthpiece for tears, the hose for cracks or bulges, and all connections for corrosion or damage.
Storage
Store your regulator in a cool, dry place, away from direct sunlight, extreme temperatures, and chemicals. Avoid kinking the hose during storage.
Professional Servicing
Your Scubapro G260 regulator requires periodic professional servicing by an authorized Scubapro technician. Refer to your Scubapro dealer for recommended service intervals, typically annually or every 100 dives, whichever comes first. Regular servicing ensures the regulator operates to factory specifications and maintains its warranty.
