1. Introduction
This manual provides essential information for the proper use, setup, operation, and maintenance of your Scubapro R105 Second Stage Regulator. The R105 is designed for reliability and ease of use, making it suitable for various diving applications. Adhering to the guidelines in this manual will help ensure the longevity and optimal performance of your regulator.
2. Included Components
The Scubapro R105 package includes the following:
- Scubapro R105 Second Stage Regulator
- Low-Pressure (LP) Hose
3. Setup
Proper setup of your R105 regulator is crucial for safe diving.
- Connecting to First Stage: Attach the low-pressure hose of the R105 second stage to an available low-pressure port on your first stage regulator. Ensure the connection is secure and hand-tightened. Do not overtighten.
- Hose Routing: Route the hose comfortably to allow for natural head movement and easy access to the mouthpiece. The R105's design allows for hose orientation to either the left or right side, accommodating diver preference.
- Pre-Dive Check: Before diving, pressurize the system and perform a functional check. Breathe from the second stage to ensure smooth airflow. Check for any air leaks.

4. Operating Instructions
The R105 regulator is designed for straightforward operation.
- VIVA Control Knob: The R105 features a dive/pre-dive (Venturi Initiated Vacuum Assist) control knob.
- Pre-Dive Position: Set the knob to the "Pre-Dive" position (often indicated by a 'PRE' or similar marking) before entering the water or when the regulator is not in use. This setting helps prevent free flow on the surface, especially when facing into a current or during entry.
- Dive Position: Once submerged and ready to breathe, rotate the knob to the "Dive" position (often indicated by a 'DIVE' or similar marking). This optimizes airflow for smooth and effortless breathing underwater.
- Purge Button: The soft, molded purge button is located on the front cover of the regulator. Pressing this button allows for a burst of air to clear water from the mouthpiece or to test airflow.
- Breathing Underwater: Breathe naturally and calmly through the mouthpiece. The R105's downstream valve design ensures consistent and reliable airflow.

5. Maintenance
Regular maintenance extends the life of your Scubapro R105 regulator and ensures its safe operation.
- Rinsing: After each dive, thoroughly rinse the regulator with fresh, clean water. Ensure the dust cap is securely in place on the first stage (if connected) to prevent water from entering. Do not press the purge button while rinsing unless the regulator is pressurized.
- Drying: Allow the regulator to air dry completely in a cool, shaded area away from direct sunlight.
- Storage: Store your regulator in a clean, dry place, protected from extreme temperatures, chemicals, and direct sunlight. Avoid kinking hoses during storage.
- Professional Servicing: Your regulator requires periodic professional servicing by an authorized Scubapro technician. Refer to your Scubapro dealer for recommended service intervals, typically annually or after a certain number of dives, whichever comes first. This ensures all internal components are inspected, cleaned, and replaced as necessary.
- Inspection: Before each dive, visually inspect the regulator for any signs of damage, wear, or corrosion on the hose, mouthpiece, and casing.
