Wick Adjustment
If forms do not seal completely, identify the wick in need of adjustment and move the red adjuster one notch closer to the sheet. If the form is too moist, move the adjuster away from the sheet. If wicks are dry, remove them and soak in hot water. For wick removal see next step.

Wick Replacement
Over time the wicks become worn and must be replaced. Remove the thumbscrews from each reservoir lid and remove the wicks. Replace the wicks with the adjuster tab facing up and the tapered and tail of the wick in the water.
