SMACO MINI SCUBA TANK INTRODUCTION

This product is suitable for wading activities such as snorkeling, recreational diving and indoor diving teaching and the maximum applicable depth is less than 10 meters underwater; When used as an underwater emergency rescue or backup air supply for professional diving equipment, the maximum applicable depth is within 30 meters underwater. In this case, it can only be used as an emergency air supply.

OPERATION TUTORIAL

Assembly

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

  1. Please check any possible air leakage when inflating. In case of any leakage, stop the inflation immediately; the gas fifilled is compressed air (it’s strictly forbidden to fifill 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;
  2. 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 fifilled. When electric pump/manual pump is used for inflation, oil-water separator shall be equipped;
  3. The compressed air fifilled 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 fifilled as required, the fifilter system or channel in the cylinder valve may be blocked to cause malfunction.

Pressure Release

Press the release valve on the top of the cylinder valve to release the pressure.
If air leakage occurs after air fifilling, 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 specifific operation is shown as follows:

  1. 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;
  2. Use only after safety hazards have been eliminated. When in use, you can breathe normally by biting the mouthpiece completely;
  3. Check whether there are foreign objects (such as sand, etc.) in the breathing cavity. If any, please clean up in time before use.

COMMON TROUBLESHOOTING

Q1.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.

Q2.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.

Q3.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.
