- Check the cooling unit and the coolant
Orientation
For add-on equipment that cannot be cooled conventionally with cooling lubricants
or hydraulic fluid due to high temperature development, separate cooling is provided
in an independent cooling circuit. The coolant used here must be checked
continuously for its condition like other coolants. Also perform a visual inspection of
the cooling unit and the supply and fluid lines as part of the servicing and
maintenance activities. Check for leaks on the system in general as well as at screw
connections, and supply and fluid lines.
This visual inspection or monitoring requires no specific knowledge
of refrigeration according to the manufacturer's documentation.
These activities can be carried out by instructed individuals with
appropriate expertise.
Due to different requirements and/or specifications of the respective
manufacturers, be sure to review the respective manufacturer's
documentation!
