Q. Why don't I add water ? The Aromamatic vaporizer does not require water to assist in the vaporizeration of essential oils. As the low heat emitted by the recessed bowl is sufficient to vaporize the essential oils withour burning them. The use of water with oil burners is necessary to control high temperature heating. Q. How long will the oil last ? This depends on the essential oil used. A base not oil (eg. Sandlawood) will take longer to vaproizer than a middle note oil (eg Lavender), which in turn will take longer to vaporizer than a top note oil (eg. Lemon). Essential oil blends will vaporize differently, according to the combination of essential oils used in the blend. Q. How often do I have to add oil to the vaporizer ? As often as you wish, remembering that the aroma from the essential oil will linger in the atmosphere fo some time after the oil has vaporizered. Q. What happens when the oil has finished vaporizing ? Nothing - No harm will come to the vaporizer when the oil has vaporized away. To get the best from the vaporizer please remeber to clean it regulary. Q. Do I have to turn the vaporizer off when the oil has vaporizered ? NO - with it's low temperature control, the Aromamatic Vaporizer allows a safe and continuous operation. Q. I can't smell the oil ? Our sense of smell is such that aroma which is continuously inhaled throught the olfactory system will cease to be recoginzed after a period of time. This is called fading. Q. My vaporizer is getting too hot ? The temperature cannot and will not vary unless the vaporizer has ceased to operate altogether. Do the Touch Test. Q. My vaporizer is not getting hot enough ? Do the Touch Test. Q. My Vaporizer is not working properly. The type of oil used will make all the difference to the performance of the vaporizer which has been designed for use with pure essential oils, rather than fragrance oils. What type of Oil are you using ? a. Is it a pure essential oil? Is it a respected brand of essential oil. b. Is it a blend of oil? If so what is in the blend? c. Is the oil diluted in a base oil? eg. Rose in 3% jojoba oil. d. Remember to clean the vaporizer regularly. Are you using water in the Aromamatic Electric Oil Vaprozer ? Have you cleaned the vaporizer recently. Q. The oil is leaking through the bowl and maybe damaging the base plate. Unless the ceramic bowl is creaked the oil cannot leak through the base plate.
