Removing Lime and Mineral Deposits

(models with optional water pan)
Use the following procedure for periodic cleaning and deliming
of the water pan.
NOTE: The lime and mineral content of the water used for
daily operation will determine how often the deliming
procedure must be performed.
NOTE: Perform this procedure when the unit will not be used
for a period of time, such as the end of the day.
1. Turn off the unit, unplug the power cord (freestanding
models), and allow the unit to cool.
2. After the unit has cooled, remove and empty the water
pan.
3. Fill the water pan with a mixture of 75% water and 25%
white vinegar to a level where it covers the lime and
mineral deposits.
4. Install the water pan with deliming solution into the unit.
5. Plug in and turn on the unit. Allow the unit to run for 30
minutes.
6. Turn off the unit and unplug the power cord (freestanding
models).
7. Allow the water pan to stand with the deliming solution for
at least two hours (the time required will vary depending
on the amount of deposits in the water pan).
8. Remove the water pan and empty the deliming solution.
9. Continue to fill and rinse the water pan with clean water
until the pan is clean.
10. Install the clean water pan into the unit. Plug in the unit and
fill the water pan as usual for daily operation (6 mm [1/4"]
of water is recommended).
NOTE: If lime and mineral deposits are still present in the water
pan, repeat this procedure and increase the amount of
time the de-liming mixture stands in the water pan.
