OPERATION TUTORIAL
4.1
Assembly
S400 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.
4.2
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.
