How should I clean the water dispenser?

Wash and disinfect the system every 3-6 months with a suitable cleaner and according to its
instructions for use.
To avoid accidents, turn on and unplug the water dispenser from the outlet before cleaning. A soft damp cloth may be used to clean the surface of the water dispenser. When necessary, a mild detergent may be used. 
Please do not use corrosive chemical solvents to clean the unit, as this may damage the surface of the water dispenser.  Do not immerse the unit in water when cleaning.
