3. Opsætningsvejledning

Proper setup is crucial for safe and effective diving. Follow these steps carefully:

1. Efterse komponenter: Before each dive, visually inspect all parts of the regulator for any signs of damage, cracks, or wear. Check O-rings for integrity.
2. Connect First Stage to Tank Valve:
   • Ensure the tank valve O-ring is present and in good condition.
   • Align the yoke fitting of the MK25 first stage with the tank valve.
   • Hand-tighten the yoke screw firmly until secure. Spænd ikke for meget.
3. Fastgør slanger:
   • Connect the high-pressure hose (usually thinner) to your pressure gauge.
   • Connect the low-pressure hose (usually thicker) to your A700 second stage.
   • Connect other low-pressure hoses to your BCD inflator and alternate air source (octopus), if applicable.
4. Tjek for lækager: Slowly open the tank valve. Listen for any hissing sounds indicating air leaks. Observe your pressure gauge to ensure it reads the tank pressure accurately and does not drop rapidly.
5. Purge Second Stage: Briefly press the purge button on the A700 second stage to ensure air flows freely.

Vigtig: Always perform a pre-dive safety check before entering the water. If you detect any issues, do not dive and consult a certified technician.

4. Betjeningsvejledning

The Scubapro MK25/A700 regulator is designed for intuitive operation. Here are key operational aspects:

4.1. Breathing Underwater

• Insert the mouthpiece of the A700 second stage into your mouth, ensuring a comfortable and secure fit.
• Breathe naturally and calmly. The air-balanced design of the MK25 first stage and A700 second stage provides smooth, effortless inhalation and exhalation.
• Monitor your air supply frequently using your submersible pressure gauge (SPG).

4.2. Adjusting Inhalation Effort (A700 Second Stage)

A700 sekund stage features a diver-adjustable inhalation effort knob. This allows you to fine-tune the breathing resistance:

• To Increase Effort (Stiffer Breathing): Turn the knob clockwise. This can be useful in strong currents or when conserving air.
• To Decrease Effort (Easier Breathing): Turn the knob counter-clockwise. This provides maximum breathing comfort, ideal for relaxed diving.

4.3. Venturi-Initiated Vacuum Assist (VIVA) (A700 Second Stage)

The VIVA switch helps prevent free-flow on the surface and assists breathing underwater:

• Pre-Dive/Surface (MIN/PRE-DIVE position): Set the VIVA switch to the "MIN" or "PRE-DIVE" position to prevent free-flow when the regulator is out of your mouth or on the surface.
• Underwater (MAX/DIVE position): Once submerged, switch the VIVA to the "MAX" or "DIVE" position. This optimizes airflow and reduces breathing effort.

5. Vedligeholdelse og pleje

Proper maintenance extends the life of your regulator and ensures its safe operation. Follow these guidelines:

5.1. After Each Dive

• Skyl grundigt: Immediately after each dive, rinse the entire regulator thoroughly with fresh, clean water. Ensure the dust cap is securely in place on the first stage to prevent water from entering.
• Soak (Optional): For a more thorough rinse, you may soak the regulator in a basin of fresh water for 15-30 minutes. Gently agitate to dislodge salt crystals.
• Tørre: Allow the regulator to air dry completely in a shaded, well-ventilated area. Avoid direct sunlight or heat sources.
• Do NOT Press Purge Button: Never press the purge button on the second stage while rinsing or soaking unless the first stage is pressurized and connected to a tank. This can force water into the second stage.

5.2. Opbevaring

• Store your regulator in a cool, dry place, away from direct sunlight, chemicals, and extreme temperatures.
• Avoid kinking or sharply bending hoses during storage.

5.3. Professionel service

Your Scubapro MK25/A700 regulator requires periodic professional servicing by a certified Scubapro technician. This typically includes:

• Årlig inspektion: An annual check-up to ensure all components are functioning correctly and to identify any potential issues.
• Eftersyn: A complete overhaul, including replacement of O-rings and other wear parts, is recommended every 100 dives or every two years, whichever comes first. Refer to your Scubapro dealer for specific service intervals.
