Inspecting/cleaning the machine compartment
As a result of air filters and leaks, test medium may collect at the bottom of
the machine compartment in the CTU.
If the machine compartment is opened, it must be well ventilated. Inspect and
clean the collecting pan of the CTU on a weekly basis.
Replacing hoses
The installed hoses are specially designed for use with the test fluid. The
hoses must be checked regularly for brittleness.
In the case of multi-shift operation, replace the hoses after two years. In the
case of single-shift operation, replace the hoses after six years.
Selecting the rinsing fluid filter / return filter
Change the filter elements of the rinsing fluid filter and return filter as per the
maintenance schedule. The filter dirt indicator is not triggered unless there is
a flow through the filters.
Note the different versions of the rinsing fluid filter and return filter:
