CLEANING OF THE UNIT
For cleaning the unit’s internal plastic parts, use a light solution of soap and water. Do not apply hard chemical
detergents on the plastics as they may lose their brightness or even get deformed. The same applies to the
external metallic surfaces. The use of hard chemicals could harm the painting of the metallic surfaces, thus
affecting the sanitary protection of the unit.
