6. Cleaning of the cooling unit
Casing: Before cleaning the units disconnect the mains plug! Please do not use water
directly on the unit, clean only with a wet cloth and a little dish liquid. The cleaning of
the units and the beverage coils (optional for this unit, if used) have to take place
according to the instructions of the industrial safety regulations.
Prevent any moisture from getting into the electric part of the unit!
The condenser fins should be cleaned at regular intervals (min. every six months and
more frequently if required) by qualified personnel to remove the accumulated air dust.
