It is very important not to overfill and not to fill directly into the central air intake tube. Drip the liquid as shown on an angle to avoid filling in the center. No matter the tank style, this more or less applies to all tanks.
Must be 18 Years old or older to purchase.
Please note that some chambers are filled from the bottom by unscrewing the bottom portion of the liquid chamber. Please feel free to email for any questions or suggestions.
