How to Use:

1.Link the atmospheric cylinder to the scuba tank.
2.Tighten the pressure-relief screw.
3.Link the respirator inflation interface.
4.Open the valve of the scuba tank and wait until it is filled with 20MPa of gas, then close the valve.
5.Unscrew the pressure-relief valve to relieve pressure.
6.Pull out the respirator and finish inflation.

Inflation Methods:

1.Inflate it at a diving shop.
2.Use the 0.3" inflatable head that can match most inflatable equipment to introduce compressed air from the atmospheric cylinder into the scuba tank(8-10s).
3.Use an electric pump(Please equip with an oil-water separator.)/air compressor(4 minutes).
4.Use a hand pump(25-30 minutes).

High-pressure Cylinder(Not Included) Inflation Steps:

1.Please do not stand directly above the product when inflating. Before inflation, open the main valve switch. After completion, please be sure to use the pressure-relief valve to relieve pressure first.
2.Spread the folding base.
3.Connect the high-pressure air cylinder with the inflation nozzle interface.
4.Tighten the pressure-relief screw.
5.Start inflating and stop inflating when the pressure gauge reaches 20MPa.
6.Loosen the pressure-relief screw.
7.Loosen the inflation nozzle interface to complete the inflation.

Notes:

1.This scuba tank does not contain any gas, so you need to inflate it yourself before use. Please check in advance if the local dive shop can inflate for you.
2.It only supports diving less than 33 ft and can only be used as a spare gas source from 33-100 ft underwater. Please never use the mini scuba tank deeper than 100 ft. The air pressure of the scuba tank cannot exceed 3000PSI.
3.The use time is the result of a test in a water area of 15ft and 50℉, which is only for reference. The actual dive time varies from person to person.
