Proper setup of your regulator system is critical for safety and performance. Always refer to a certified SCUBAPRO technician for initial assembly and any complex adjustments.

1. A 'chiad Stage Ceangal: Dèan cinnteach gu bheil a’ chiad stage (MK25 EVO) is securely connected to the dive tank valve. For INT connectors, ensure the O-ring is in place and the yoke screw is tightened firmly by hand. Do not overtighten.
2. Ceangal Hose: Connect the primary second stage (A700), alternate air source, pressure gauge, and BCD inflator hose to the appropriate low-pressure and high-pressure ports on the first stage.
   • Two opposing high-pressure ports allow flexible gauge positioning.
   • Four high-flow and one axial super-high-flow low-pressure ports are available on the swivel turret.
3. Sgrùdadh lèirsinneach: Before pressurizing the system, visually inspect all O-rings, hoses, and connections for any signs of damage or wear.
4. Foillseachadh: Slowly open the tank valve while observing the pressure gauge. Listen for any leaks. If leaks are detected, close the tank valve and re-check connections.
5. Deuchainn gnìomh:
   • Breathe from the primary second stage to ensure smooth airflow.
   • Test the purge button on the second stage.
   • Check the BCD inflator for proper operation.
   • Verify the pressure gauge reads accurately.

Stiùireadh Obrachaidh

The MK25 EVO/A700 system is designed for intuitive use. Familiarize yourself with its controls before diving.

1. Sgrùdadh Ro-Dàibhidh: Always perform a thorough pre-dive check, including:
   • Confirming tank pressure.
   • Testing primary and alternate air sources.
   • Checking BCD inflation/deflation.
   • Verifying all connections are secure.
2. Inhalation Effort Adjustment: The A700 second stage features a diver-adjustable inhalation effort knob. Turn clockwise to increase breathing resistance (useful to prevent free-flow on the surface or during entry) and counter-clockwise to decrease resistance for easier breathing underwater.
3. VIVA Switch (Venturi Initiated Vacuum Assist): The coaxial VIVA switch controls free flow. Set it to "MIN" or "PRE-DIVE" on the surface to prevent free-flow. Set it to "MAX" or "DIVE" underwater for optimal breathing performance.
4. Putan glanaidh: The large purge button on the A700 second stage allows for easy clearing of water from the regulator. Press firmly to activate.
5. Cold Water Diving: The Extended Thermal Insulating System (XTIS) provides anti-freeze protection. However, in extremely cold water, always breathe slowly and avoid rapid, deep breaths to minimize the risk of free-flow.

Regular maintenance is essential to ensure the longevity and safe operation of your SCUBAPRO regulator system.

• A' sileadh: After each dive, thoroughly rinse the entire regulator system with fresh, clean water. Ensure the dust cap is securely in place on the first stage before rinsing to prevent water entry. Do not press the purge button while rinsing unless the first stage is pressurized and connected to a tank.
• A 'tiormachadh: Allow the regulator to air dry completely in a shaded, well-ventilated area, away from direct sunlight.
• Stòradh: Store the regulator in a cool, dry place, protected from extreme temperatures, chemicals, and direct sunlight. Avoid kinking hoses.
• Seirbheis Proifeiseanta: Your SCUBAPRO regulator requires periodic professional servicing by an authorized SCUBAPRO technician. Refer to your warranty card or SCUBAPRO's official guidelines for recommended service intervals, typically annually or every 100 dives, whichever comes first. This includes inspection, cleaning, and replacement of internal components and O-rings.
• Intermediate Pressure Adjustment: The external intermediate pressure adjustment should only be performed by a qualified technician.
