Cleaning / Disinfection
Clean in general
before first operation,
•
• when necessary (depending on pollution degree),
• periodically (acc. to your internal cleaning schedule).
If the surface became dirty by oil or grease containing substances they have to be cleaned
immediately.
All outer surfaces of the emergency stops / switch-off devices (SNH 0300) are suitable for
wet cleaning and disinfection.
The emergency off button (all buttons with the operating element SNH 0300) may only be
cleaned with appropriate cleansers. Observe the information on material in the chapter 8
"Technical data" on page 23.
We recommend the use of usual low concentrated cleaning and disinfection agents with a
low acidity. Cleaning and disinfection agents in highly concentrated solutions are not suita-
ble.
Use for the cleaning/disinfection, if necessary,
Cleaning utensils which are clean and satisfactory hygiene condition,
•
• Cleaning utensils which do not absorb any elements to the surface to be cleaned (e.g.
clean and fluff-free cloth)
Do not use for cleaning/disinfection:
• sharp, hard or pointed object (e.g. steel wool and steel brushes) which can damage the
surface,
• abrasive treatments which negatively affect the surface roughness of the material.
The use of high pressure cleaners for cleaning/disinfection is not recommended.
Check all outside visible parts regularly and after operation. In case of damage the actua-
tors have to be exchanged by equivalent hygienically designed units.
Disposal
Correct disposal in compliance with the national regulations and legislation must be pro-
vided.
