RECOMMENDATION:
Don't use the dishwasher to clean the cover nor
the tray. Doing thus reduces the durability of the parts owing to the high
temperatures of the automatic washing process. Follow the recommenda-
tion and avoid cleaning at high temperatures.
For cleaning both parts use a soft cloth soaked in soap and water suitable
for crockery.
Under no circumstances must abrasive products be used nor any anti-lime
scale product.
