Cleaning

WARNING
Danger of accident and component damage
Danger of accident and component damage due to improper cleaning.
Cleaning the cooling units using water jets, steam jet cleaners or high-pressure cleaners or sharp objects may damage the
electrical and electronic components. Malfunctions may cause accidents.
• Do not clean with a water jet, high-pressure cleaner or flammable cleaning agents.
• Protect electrical components against moisture penetration.
• Do not use pointed or sharp-edged objects when cleaning the blades. They must not be compressed or damaged.
The frequency of cleaning intervals depends on the respective operating conditions. Perform the following cleaning operations
regularly to ensure safe and reliable operation of the cooling units:
• Clean the heat exchangers of dust or ambient residues.
• Regularly check the condensate drain.

Internal air circuit
The internal air circuit of the cooling unit (cold area) is protected against being soiled by the environment when installed
correctly on the switch cabinet. No cleaning is necessary here under normal circumstances.
External air circuit
The external air circuit of the cooling unit (hot area) can be soiled by contaminated air. The external air circuit must therefore be
cleaned regularly.
Fans
The fans can be dismantled easily for maintenance and cleaning.
