SMACO S700 Mini Scuba Tank with Full Face Diving Mask

Product Information

Specifications

• Language Catalog: EN English language, DE Deutsche, RU, IT italiano, CN
• Maximum Applicable Pressure: 3000psi/200bar/20MPa
• Cylinder Volume: 1.9L

Product Structure

• Main Valve Switch : It can be switched off when not in use to avoid air leakage during storage. As the main flow switch of the air outlet channel, it needs to be switched on when in use.
• Medium Pressure Tube: Connecting pipe to output air.
• High-Pressure Cylinder : 1.9L high-pressure cylinder.
• Pressure Gauge: Luminous pressure gauge made of full stainless steel can check the amount of remaining air in the cylinder at any time, even in underwater darkness.
• Explosion-Proof Valve: Provides overpressure protection.
• 8mm Inflation Plug Interface: For air filling.
• Decompression Chamber: High-pressure air in the cylinder is decompressed and output through the decompression chamber.
• Release Valve: Press to release the pressure and discharge the air out of the cylinder.
• Mouthpiece: For divers to bite and breathe through, connecting the inlet and outlet channels of the breathing valve.

Operation Principle

1. When the diver bites the mouthpiece and inhales, the pressure in the cavity decreases, prompting the release valve to open downward. This reduces the air pressure in the primary pressure reducing valve and allows it to flow through the medium pressure tube into the secondary breathing valve cavity and then into the oral cavity through the mouthpiece.
2. When the diver bites the mouthpiece and exhales, the exhaled gas flows into the cavity, increasing the pressure. This prompts the opening of the one-way silicone gasket at the bottom of the secondary breathing valve, and the gas is discharged to the outside through the two exhaust holes.

Operation Tutorial

1. Assembly
   The S700 scuba consists of one primary pressure reducing valve, one high- pressure gas cylinder, one medium-pressure tube, and one secondary breathing valve. When receiving the product, please check for any possible missing parts. Remove the primary pressure reducing valve screw protection sleeve and check the thread connection. After a careful check, tighten the cylinder valve and then install the medium-pressure tube and secondary breathing valve.

2. Inflation
   Please check for any possible air leakage when inflating. In case of any leakage, stop the inflation immediately. The gas filled should be compressed air (it is strictly forbidden to fill in pure oxygen or other gases harmful to the human body). When the air pressure in the cylinder reaches 3000psi/200bar/20MPa, stop the inflation immediately to avoid any accidents.

PRODUCT STRUCTURE

OPERATION PRINCIPLE

1. When the diver bites the mouthpiece and inhales, the pressure in the cavity decreases to prompt the release valve to open downward so that the air pressure is reduced in the primary pressure reducing valve and flows through the medium pressure tube into the secondary breathing valve cavity and then into the oral cavity through the mouthpiece;
2. When the diver bites the mouthpiece and exhales, the exhaled gas flows into the  cavity to increase the pressure in the cavity, so as to prompt the opening of the  one-way silicone gasket at the bottom of the secondary breathing valve, and the gas is discharged to the outside through the two exhaust holes.

OPERATION TUTORIAL

Assembly
S700 scuba consists of one primary pressure reducing valve, one high-pressure gas cylinder, one medium-pressure tube and one secondary breathing valve. When receiving the product, please check any possible missing parts. Remove the primary pressure reducing valve screw protection sleeve and check the thread connection. After careful check, please tighten the cylinder valve and then install the medium-pressure tube and secondary breathing valve.

Inflation

• Please check any possible air leakage when inflating. In case of any leakage, stop the inflation immediately; the gas filled is compressed air (it’s strictly forbidden to fill in pure oxygen or other gases harmful to human body). When the air pressure in the cylinder reaches 3000psi /200bar/20MPa, stop the inflation immediately to avoid any accidents;
• Common inflating method: when using an electric air pump or a scuba adapter, the inflating tool needs to ensure that its working pressure is more than 3000psi/200bar/20Mpa, otherwise our products cannot be filled to  3000psi/200bar/20Mpa. When using an electric air pump, an oil-water separator must be equipped to filter the air;
• The compressed air filled shall meet the requirements of human breathing to ensure the air is pure and harmless to human body. If the pure compressed air suitable for human body is not filled as required, the filter system or channel in the cylinder valve may be blocked to cause malfunction.

Pressure Release
Press the release valve on the top of the secondary breathing valve to release the pressure. If air leakage occurs after air filling, release the pressure in this way and check the malfunction.

How to Use

• Before use, please check any possible air leakage or water seeping into the breathing cavity of the secondary breathing valve. In case of air leakage, stop using it immediately. In case of water seepage, please drain the water before use. The specific operation is shown as follows:
• Keep all the mouthpiece in mouth and bite the silicon part with teeth, blow 2-3 times into the cylinder valve to ensure the water in the cavity of the secondary breathing valve has been fully discharged, and then have normal breathing with the mouth;
• Keep all the mouthpiece in mouth, bite the silicone part with teeth and shut the mouth tightly. Press the pressure release valve of the secondary breathing valve to discharge the water in the cavity of the secondary breathing valve by the released air, and then have normal breathing with the mouth;
• Check whether there are foreign objects (such as sand, etc.) in the cavity of the secondary breathing valve. If any, please clean up in time before use;
• Use only after safety hazards have been eliminated. When in use, you can breathe normally by biting the mouthpiece completely.

COMMON TROUBLESHOOTING

1. Air leakage at the connection between pressure gauge and cylinder valve / Air leakage at the connection between 8mm inflation plug and the primary pressure reducing valve?
   Answer: Use a wrench to tighten the pressure gauge and the inflation plug to eliminate the malfunction.

2. Air leakage at the connection between the primary pressure reducing valve and the cylinder?
   Answer: Replace the rubber ring at the bottom of the primary pressure reducing valve and tighten to the cylinder to eliminate the malfunction.

3. Air leakage at the port of inflation plug?
   Answer: Remove the inflation plug, take off the O-shaped rubber ring at the bottom and clean/replace with clean water, wipe off the water and reinstall back to the original place. Make it tightened to eliminate the malfunction.
