Keep the unit level. 2. Unscrew reservoir tank lid on top of Fog Bubble Machine and fill with fog solution (Not Included) and bubble solution (Not Included). Close the reservoir tank lid tightly. Ensure there is enough fluid in the tank before using this machine. 3. Plug the A/C power cord into a standard A/C grounded wall outlet. 4. Bubble Mode: Push the function button to position “I”, this machine is a bubble machine only, it will make tons of colorful bubbles, no smoke filled bubbles. 5. Smoky Bubble Mode: Push the function button to position “II”, It will take approximately 3 to 7 minutes to warm up. When fully heated, the LED indicator will light up green, The machine will produce magical smoky bubbles (fog filled bubbles) continuously. When the LED indicator light change to flash, signaling the Fog Bubble Machine needs to refill fog solution. 6. Unplug when not in use.

TROUBLE SHOOTING CHECKLIST Th is i tem is not a toy and sho uld be used f or d ecorative purposes only. If y our Fog Bubble Machine is not working, t he problem may be: 1. The power s ource i s disab led or t he cord may be unplugge. 2. There is not enough Fog Solution and Bubble Solution in the reservoir tanks. FREQUENTLY ASKED QUESTIONS ( FAQ’s) 1. Is artificial fog safe to breathe? Most fog machines use fog solution made of a combinatio n of water and a chemical called glycol which has been found to be safe and is not considered hazardous to humans. Fog machines and fog solution can generally be used without problems. However, some people do complain of respiratory problems or throat irritation when exposed to theatrical fog. Because the fog can be irritating or drying, extended periods of exposure to the fog should be minimized. If the product is used indoors, you should make sure the room has adequate ventilation. It is a good idea not to breathe the fog for extended periods of time. DO NOT expose the fog at close range to known asthmatics or allergenic sensitive people. 2. Will fog smoke set off smoke detectors or sprinkler systems? Yes, it is possible that the water-based particles could set off some types of smoke detectors. Usually, this is only a problem with optical-type detectors, because they sense the particles as smoke. Sprinkler systems, on the other hand, are usually triggered by heat, so the fog in the air will not activate heat- activated sprinkler systems. We recommend you run a test when used indoors to see if the fog will activate any smoke detectors. Also, when using the produ…
