4. Produktet er slutview og komponenter
The S700MAX regulator is the central control unit for your diving system. It integrates several key functions for safe and efficient operation.
- Luftafbryder: Controls the airflow from the tanks.
- Explosion-proof Valve: A safety mechanism to prevent over-pressurization.
- Inflation Interface: 8mm port for connecting inflation sources.
- Pressure Reduction Chamber: Reduces high-pressure air from the tanks to a breathable pressure.
- Trykmåler: Displays the remaining air pressure in the tanks.
- Secondary Regulator: Delivers air to the diver's mouth via the mouthpiece.
- BCD Connector: Allows connection to a specific buoyancy control device.

5. Opsætning og montering
Follow these steps to assemble your SMACO S700MAX system:
- Connect Cylinders to Regulator: Carefully screw the two 1.9L scuba cylinders into the S700MAX regulator. Ensure a secure, hand-tight connection to prevent air leaks.
- Fastgør slanger: Connect the high-pressure hose from the regulator to the pressure gauge, and the low-pressure hose to the secondary regulator (mouthpiece).
- Install in Diving Vest: Place the assembled tank system into the designated pocket of the diving vest. Secure it using the straps and buckles provided on the vest. The vest is designed for a labor-saving and anti-drop fit.
- Connect Full Face Mask: Attach the secondary regulator's mouthpiece to the full face mask as per the mask's instructions.

6. Inflation Methods
The SMACO S700MAX system offers multiple ways to refill your tanks:
- Dive Shops: The most common and recommended method. Most professional dive shops can refill your tanks. For non-certified customers, it is advisable to confirm with the dive shop in advance if they will inflate your tanks.
- Luftkompressor: If you own a high-pressure air compressor suitable for scuba tanks, you can inflate the tanks yourself. Ensure the compressor is rated for 3000 Psi (200 Bar / 20 Mpa) and has the correct 8mm inflation interface.
- Scuba Adapter: You can use a scuba adapter to transfer air from a larger scuba tank to your SMACO mini tanks.
The diameter of the diving tank filling interface is 8mm, and the maximum inflation pressure is 3000 Psi / 200 Bar / 20 Mpa. Always ensure the air source provides clean, dry, breathable air.

7. Betjeningsvejledning
Once your tanks are filled and the system is assembled, you are ready for diving:
- Tjek før dykket: Before entering the water, perform a thorough pre-dive check. Verify all connections are secure, the pressure gauge reads full, and the air switch is in the OFF position.
- Donning Equipment: Put on the diving vest with the attached tanks and secure all straps. Don your full face mask.
- Entering Water: Enter the water safely.
- Start luftstrømmen: Once submerged and ready to breathe, slowly turn the air switch to the ON position. Take a few shallow breaths to ensure air is flowing correctly.
- Monitortryk: Continuously monitor your pressure gauge throughout the dive. Plan your dive to ensure you have sufficient air for ascent and safety stops.
- Diving Depth and Time: This system is suitable for diving depths up to 33 feet (10 meters) and provides approximately 30-45 minutes of breath support. These times are estimates and can vary significantly based on individual breathing rates, exertion, and environmental conditions.
- Opstigning: Always ascend slowly, following safe diving practices to avoid decompression sickness. Turn the air switch to the OFF position once you are out of the water or no longer require air.

8. Travel Guidelines
The SMACO S700MAX mini diving tanks can be taken on an airplane, provided specific conditions are met:
- Disassemble Regulator: The S700MAX regulator must be completely disassembled from the two 1.9L cylinders.
- Tomme tanke: Ensure there is absolutely no air remaining in the cylinders. The tanks must be completely depressurized.
- Check Airline Regulations: Always verify the latest regulations with your specific airline and airport security prior to travel, as rules can vary.

9. Vedligeholdelse og opbevaring
Proper maintenance and storage will extend the life of your SMACO S700MAX system:
- Skyl efter brug: After each dive, thoroughly rinse all components with fresh water to remove salt, sand, and chlorine.
- Tør helt: Allow all parts to air dry completely in a shaded, well-ventilated area before storage.
- Inspicer regelmæssigt: Periodically inspect hoses, O-rings, and connections for any signs of wear, cracks, or damage. Replace worn parts immediately.
- Opbevar korrekt: Store the system in a cool, dry place away from direct sunlight and extreme temperatures. Keep tanks partially pressurized (e.g., 100-200 Psi) to prevent moisture ingress, but never store fully pressurized for extended periods.
- Professionel servicering: It is recommended to have your regulator and tanks professionally serviced annually or as recommended by a certified technician.
10. Fejlfinding
Dette afsnit omhandler almindelige problemer, du kan støde på:
- Luftlækage: Check all connections for tightness. Inspect O-rings for damage or displacement. Ensure the air switch is fully closed when not in use.
- Low Air Pressure Reading: Confirm tanks are fully inflated. If the gauge reads low after inflation, check for leaks.
- Vejrtrækningsbesvær: Ensure the air switch is fully open. Check for any obstructions in the mouthpiece or regulator. If issues persist, discontinue use and seek professional inspection.
- Regulator Malfunction: If the regulator is not functioning correctly (e.g., free-flowing air, difficulty turning switch), do not attempt to repair it yourself. Contact SMACO customer support or a certified technician.
