Maintenance
You must perform maintenance tasks at regular intervals.
We recommend setting the maintenance times in advance in an operations journal or
calendar.
The maintenance cycle primarily depends on the following:
• The facility
• The installation conditions
• The medium being measured
CAUTION
!
Risk of injury if medium escapes
‣
Prior to performing any maintenance task, make sure that the process pipe is
unpressurized, empty and rinsed.
5.1
Cleaning the assembly
• Use suitable cleaning solutions (see "Cleaning agents" section) to remove light dirt and
fouling.
• Heavy dirt can be removed with a soft brush and a suitable cleaning agent.
• To remove stubborn dirt, soak the parts in a cleaning solution. Then clean the parts with a
brush.
Six months is a typical cleaning interval for drinking water, for example.
