Precautionary measures
The smoke machine is waterproof. All connections in the housing are sealed. However, you should avoid dropping the tray with the solution, as water may get inside through the purge hole. If this does happen, you need to remove the upper part of the smoke machine housing and pour out the soapy solution that ends up inside. Remove the battery pack and the battery from it. Dry everything thoroughly. If there is a large amount of solution inside the smoke machine and it gets into the glycerin filling container, all the filled glycerin must be replaced before turning it on.
