1. પરિચય

This manual provides essential information for the proper use, setup, operation, and maintenance of your SCUBAPRO MK11 DIN 300/C370 Diving Regulator System. This system is designed for reliable air delivery during diving activities, combining the compact MK11 balanced diaphragm first stage with the C370 second stage.

2. સેટઅપ અને એસેમ્બલી

Proper assembly of your regulator system is crucial for safe diving. Follow these steps carefully:

1. ઘટકો તપાસો: Before each dive, visually inspect all components of the MK11 first stage and C370 second stage for any signs of damage, wear, or contamination. Ensure all O-rings are present and in good condition.
2. Connect First Stage to Tank: The MK11 first stage features a DIN 300 connector. Ensure the tank valve is clean. Screw the DIN connector firmly into the tank valve by hand until snug. Do not overtighten.
3. Hose Routing: The MK11 first stage is equipped with two high-pressure (HP) ports, two high-flow low-pressure (LP) ports, and two standard LP ports. Connect your primary second stage (C370), alternate air source, pressure gauge, and BCD inflator hose to the appropriate LP and HP ports. Optimize hose routing for comfort and accessibility.
4. Connect C370 Second Stage: Attach the C370 second stage hose to one of the low-pressure ports on the MK11 first stage. Ensure a secure connection.
5. દબાણ તપાસ: Slowly open the tank valve and check for any air leaks. Observe the pressure gauge to ensure it reads correctly.

મહત્વપૂર્ણ: If you are unsure about any assembly step, consult a certified diving technician or instructor.

3. ઓપરેશન

The C370 second stage offers user-adjustable controls for optimal breathing performance.

• Inhalation Effort Control Knob: The C370 features an inhalation effort control knob. Turning this knob allows you to fine-tune the breathing resistance. Turn clockwise for increased resistance (useful for preventing free-flow on the surface or during entry) and counter-clockwise for reduced resistance (for easier breathing at depth).
• Dive/Pre-Dive Lever: A small coaxial dive/pre-dive lever is located on the C370. In the "Pre-Dive" position, the regulator is detuned to prevent free-flow before entering the water. In the "Dive" position, the regulator is fully operational for optimal breathing performance underwater. Always switch to "Dive" before descending.
• પર્જ બટન: The large purge button on the front of the C370 is designed for easy activation, even when wearing thick gloves. Pressing this button releases a burst of air to clear water from the second stage.

The MK11 first stage provides constant and effortless airflow, unaffected by depth, tank pressure, or breathing rate, thanks to its balanced diaphragm design and environmentally sealed body.

4. સંભાળ અને જાળવણી

Regular care and maintenance will ensure the longevity and reliable performance of your SCUBAPRO regulator system.

• રિન્સિંગ: 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 to prevent water from entering. Operate the purge button several times during rinsing to flush out any salt or debris from the second stage.
• સૂકવણી: Allow the regulator to air dry completely in a shaded, well-ventilated area before storage. Avoid direct sunlight.
• સંગ્રહ: Store the regulator in a cool, dry place, away from direct sunlight, extreme temperatures, and chemicals. Avoid kinking hoses.
• વ્યવસાયિક સેવા: Your SCUBAPRO regulator requires periodic professional servicing by an authorized SCUBAPRO technician. Refer to your local SCUBAPRO dealer for recommended service intervals, typically annually or every 100 dives, whichever comes first. The environmentally sealed design of the MK11 first stage helps protect internal components from water and pollutants, but regular inspection and service are still essential.

5. મુશ્કેલીનિવારણ

This section addresses common issues you might encounter. For any problems not listed or if you are unsure, always consult a certified SCUBAPRO technician.

• Free-Flowing Regulator:
  • Ensure the dive/pre-dive lever is in the "Pre-Dive" position on the surface.
  • Adjust the inhalation effort control knob clockwise to increase resistance.
  • Check for debris in the second stage. Rinse thoroughly.
  • If persistent, professional service is required.
• Hard Breathing:
  • Ensure the dive/pre-dive lever is in the "Dive" position.
  • Adjust the inhalation effort control knob counter-clockwise to decrease resistance.
  • Check for kinks in the hose.
  • If persistent, professional service is required.
• એર લીક્સ:
  • Check all hose connections for tightness.
  • Inspect O-rings on the first stage DIN connector and hose connections for damage.
  • If a leak persists or is from within the regulator body, discontinue use and seek professional service immediately.
