10.1 Cleaning
Disconnect the power plug before starting any maintenance work.
The identification plate has always to be kept in easily legible condition and has
not to be removed.
Remove external dirt from time to time with some form of cold cleaner.
Use only cold cleaners to avoid damaging the paintwork or removing the lettering.
The equipment should be cleaned at regular intervals to ensure trouble-free
operation.
It requires only normal cleaning (sponge, damp cloth, mild detergent) and no further
chemical additives.
