Working with pressure washers

The HMI device can be used on machines that are cleaned with high pressure.
NOTICE
Damage caused by steam cleaners
Hot steam can damage the HMI device. Do not clean the HMI device with steam cleaners.
Risk of contamination by high-pressure cleaner
When high-pressure cleaners are used, areas that have already been cleaned can be
contaminated again:
• Due to particles of dirt or aerosols swirling up
• Due to draining wastewater
This is why high-pressure cleaners are generally not recommended for machine and plant
cleaning in the hygiene sector.
