Chemical Resistance
Impermissible and unsuitable cleaning agents may cause damage to the HMI device (see
General cleaning instructions).
Stainless steel front
Information on the resistance of stainless steel:
●
The stainless steel surface is not fully resistant against the chemicals listed below:
–
Hydrochloric acid
–
Sulphuric acid
–
Sodium hydroxide
–
Chlorine
–
Chlorides
Do not clean the stainless steel surface with these chemicals or with similar acids or
caustic solutions.
●
Acid steam develops, for example, when tiles are cleaned with hydrochloric acid, and is
also harmful to the stainless steel. If the stainless steel parts are unintentionally
contaminated with hydrochloric acid, rinse these off immediately with plenty of water.
●
Clean the stainless steel surface with a cleansing agent without active chlorine.
Glass front
The edge grouting has sufficient chemical resistance when used as intended (see Product
overview).
Mounting seal
The mounting gasket made of EPDM is approved for food according to
FDA 21 CFR 177-2600.
