Cylinder Volume

PRODUCT STRUCTURE

OPERATION PRINCIPLE

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 flows out into the oral cavity through the mouthpiece;
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 one-way silicone gasket in the valve at the bottom of the cylinder to open, and the gas is discharged to the outside through the two exhaust holes.

OPERATION TUTORIAL

Assembly

S300 PLUS scuba is divided into two parts: the cylinder valve and high- pressure cylinder. When receiving the product, please check any possible missing parts.
Remove the screw protection sleeve at the bottom of the cylinder valve and check the thread connection. After careful check, please tighten the cylinder valve and have it inflated for use.

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 Inflation Methods: electric pump inflation, manual pump inflation and adapter inflation. When the aforesaid tools are used, please ensure that the pressure can reach 3000psi/200bar/20Mpa, otherwise the cylinder will not be fully filled. When electric pump/manual pump is used for inflation, oil-water separator shall be equipped;
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.

OPERATION TUTORIAL

Pressure Release

Press the release valve on the top of the cylinder 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 breathing cavity of the cylinder 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:

Before use, please check any possible air leakage or water seeping into breathing cavity of the cylinder 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, bite the silicon part with teeth and shut the mouth tightly. Press the silicone cap on the top of cylinder valve to discharge the water in the breathing cavity by the released air, and then have normal breathing with the mouth;
Check whether there are foreign objects (such as sand, etc.) in the breathing cavity. 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

Air leakage at the connection between pressure gauge and cylinder valve / Air leakage at the connection between 8mm inflation plug and cylinder valve?
Answer: Use a wrench to tighten the pressure gauge and the inflation plug to eliminate the malfunction
Air leakage at the connection between the cylinder valve and the cylinder?
Answer: Take out the gasket and other accessories at the bottom of the cylinder valve in order, rearrange them properly and reinstall back in order. The valve should be aligned with the screw of cylinder and tightened to eliminate the malfunction.

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.
