hot or boiling liquids into the bottle, as this will damage the spray system.
To reduce the risk of fire or explosion, liquids with a flash point higher than
140°F (60°C) should be used.
It is NOT recommended to use bleach or hydrogen peroxide. These chemical
reagents will corrode metal parts or reduce the service life of spray system
components such as bottle and pipes.
Check the equipment before each use to ensure no impurities in the cavity
Do NOT use powder or abrasive chemicals
The spray area must be well ventilated.

electrostatic shock to the user. It is recommended to bring a secondary
conductive object (such as a key) to touch the surface and dissipate the charges.
In the use, always pay attention to prevent impurities such as hair and
accessories from entering the air inlet
