12.1 Maintenance tasks
12.1.1 Recommended maintenance
Maintenance work has to be carried out at regular intervals to ensure the efficient
operation of the sampler.
The maintenance work comprises:
• Replacing the wear parts
• Cleaning the device
The cleaning intervals depend heavily on:
• The medium
• The ambient conditions of the sampler (dust etc.)
• The programming intervals
For this reason, adapt the cleaning intervals to your specific requirements but always
ensure that these cleaning tasks are performed regularly.
Replacing wear parts
Wear parts are replaced by Endress+Hauser Service at one- and two-year intervals. Please
contact your local sales center in this regard.
Endress+Hauser offers its customers a maintenance contract. A maintenance contract
increases the operational safety of your device and reduces your staff's workload. Ask
your Endress+Hauser Service Organization for detailed information on maintenance
contracts.
