SCENES TO BE USED
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.

PRODUCT INTRODUCTION01
02
Pressure Gauge
Luminous pressure gauge
made of full stainless steel
can check the amount of
remaining air in the cylinder
any time in the
underwater darkness
360° Rotating Interface
360° free rotation
Main Valve Switch
it can be switched off when not
in use to avoid air leakage during
storage. As the main flow switch
of air outlet channel, it needs to
be switched on when in use
High-Pressure Cylinder
1L high-pressure cylinder
Medium Pressure Tube
Connecting pipe to output air
Decompression Chamber
high-pressure air in the
cylinder is decompressed
and output through the
decompression chamber
Explosion-Proof Valve
it provides overpressure
protection
8mm Inflation Plug
Interface for air filling
Release Valve
press to release the pressure
and discharge the air out of
the cylinder
Mouthpiece
for diver to bite the
mouthpiece for breathing,
connect the inlet and outlet
channels of breathing valve
PRODUCT STRUCTURE02
03
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;
OPERATION PRINCIPLE
3.1
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 TUTORIAL04
Assembly
S400 PLUS 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 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 TUTORIAL04
4.3 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;
Use only after safety hazards have been eliminated. When in use, you can breathe
normally by biting the mouthpiece completely;
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.

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?
5.1
COMMON TROUBLESHOOTING05
Answer: Use a wrench to tighten the pressure gauge and the
inflation plug to eliminate the malfunction.
Air leakage at the connection between the primary pressure reducing valve
and the cylinder?
5.2
Answer: Replace the rubber ring at the bottom of the primary
pressure reducing valve and tighten to the cylinder to eliminate
the malfunction.
Air leakage at the port of inflation plug?
5.3
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.

Storage Conditions:
It should be stored in the place with ambient temperature of 5°C~30°C
and relative humidity of 40%~70%;
It should not be placed within one meter from the heat source and in the
direct sunlight;
The warehouse where scuba is stored should not have oils, acids, alkalis
and other gaseous substances that can damage rubber material.
Transportation Conditions:
SMACO S400 PLUS scuba is small in size and light in weight, so it’s very
convenient to carry. Violent shocks and vibrations during transportation
should be avoided. It should be kept clean without contacting with oils,
acids, alkalis and other substances that damage rubber and fabrics.
Deposite Conditions
The product should be disposed if the following cases occur:
The product itself is damaged, that is, it meets the disposal requirement
and cannot be used any more; for example, the cylinder case is broken, the
screw of cylinder valve is damaged or de-formed, the cylinder valve or
cylinder is deformed;
Only two years of service life. When the product reaches the expiration date,
it meets the disposal requirement so it’s strictly forbidden to use it any more.
