Mineral water:
If mineral water is used in your water cooler, it should be cleaned once each
month to remove scale that can form inside the unit.
Leave the cleaning solution (a mild vinegar solution or 2% citric acid
solution) inside the reservoirs for 30 minutes. After 30 minutes, rinse and
flush as described above. Repeat as necessary.
H. Storage
If unit is being stored, turn off power, disconnect and drain all water from
reservoirs and lines. Ensure compartment is clean and dry.
Routine cleaning:
Turn off and unplug unit.
Remove bottle and water inlet ring by rotating counterclockwise and lifting out.
Pour about 3.5 l of a mild vinegar solution or 2% citric acid solution down into the
2 holes, or until no more solution drains away into the holes. Allow to sit 10-15
minutes. Run the solution through the spigots and through the back drains. Fill
the reservoirs 2-3 times with water and rinse through spigots and back drains.
The outer cabinet should be wiped with a soft cloth only. Do not use harsh
cleansers.
