Assembly: Carefully remove the parts from the packaging. Connect one end of the clear plastic tube to the air pump outlet and the other end to the air inlet of the well. Place the glass nebulizer over the jet.

Operating Instructions: Pour 15 to 20 drops of oil directly into the well approximately one-quarter inch deep. You only need enough oil for the mist to start coming through the top of the nebulizer. You may wish to place the bottle of essential oil upside down in the well located next to the nebulizer. Be sure that the plastic orifice (drop reducer) is still in the bottle opening. Push down on the switch that is attached to the electrical cord. Turn the knob on the flow control valve until the arrow points in the direction of the tube.

The pump is not compliant with EU voltage. They are designed for use with 120 volts. (Please contact the UK office for a pump that is EU compatible.)

Changing Oils: You can change from a single oil to a blend or from a blend to a single. Simply allow the first oil to be completely diffused. If there is too much oil left to diffuse, use the enclosed eyedropper to return it to its bottle.

Mixing Oils: Avoid mixing two or more blends, as this may change the desired results. A single oil may be added to a blend, or two single oils may be mixed together and diffused. Avoid using vegetable oils such a V-6 Mixing Oil, massage oils, or other vegetable-based oils in your diffuser. Oils of this thickness may clog the diffuser.

Cleaning the Diffuser: Disconnect the plastic tubing from the air outlet on the well. Remove the glass nebulizer and clean it with soapy water or rubbing alcohol. Seal both ends of the nebulizer and shake. Rinse with water or alcohol. Let dry completely. Use a blow dryer on low heat for quicker drying. Thoroughly clean the inside of the well with rubbing alcohol or soapy water.

How long should a diffuser be used?: In the home, a diffuser may be used for any length of time-anywhere from 5 minutes to continuous use. Short periods of 5 to 15 minutes are recommended for anyone who is experiencing oils for the first time. In large offices or commercial areas, the diffuser should be used for 15 to 30 minutes at a time until everyone in the area becomes acquainted with the oils. After that point, it may run continuously.

Cautions: The glass nebulizer should always be placed over the jet before starting the diffuser. Low grade oils or "perfume essences" may clog the air jet. The diffuser should be placed on a steady surface that is protected in case spills occur.

Troubleshooting: When a diffuser is functioning properly, you can see oil being projected through the glass nebulizer as it turns into a mist. If this is not happening, check the following: No air output. Be sure the pump is plugged into an active electrical socket and the tubing is properly attached. Check to make sure that the switch on the electrical cord is pushed down, and the knob on the control valve is turned with the arrow pointing to the tubing. Make sure there is oil in the well or in the bottle.

The Well (with jet), a Pump, a Glass Nebulizer, an Oil Dropper, and Tubing.

NOTE: The well and jet is one unit. Removing the jet will render the diffuser inoperable. Item 3809, the jet replacement, is not intended as a replacement for the jet in this diffuser type.
