How

se:

1. Ensure the bottle is empty of any objects, then fill it with tap water. 

Measure out the appropriate amount of salt (see guide) and pour it in. 

Shake gently to dissolve.

2. Gently screw on the spray nozzle, leaving some slack so that air can 

escape.

3. Connect the USB Charging Cable and plug into power. The device will 

emit a buzz to confirm connection.

4. Press the base's power button to begin. You will see the colored lights 

change and bubbles form during the 10 minute process.

5. The device will buzz 3 times when complete. Remove the cable and 

tighten the spray nozzle. You are now ready to disinfect!

6. When finished, empty, rinse, and dry the bottle inside and out. Store in 

a cool, dry area.

Troubleshooting

-If you have difficulty spraying, be sure the adjustable nozzle is in the 

correct position. Rotate if necessary until you can spray easily.

-If the hydrolyzing process generates fewer bubbles than normal, you may 

need to clean the base's electrodes. Pour enough lemon juice, citric, acid, 

potable vinegar or another non-toxic cleaning agent into the bottle to

cover the electrodes. Let it soak 1-2 hours, then rinse with clean water and 

air dry in a well-ventilated area.
