Maintenance and service of water cooling (option)

Visual inspection
As part of the inspection of the complete system, Siemens recommends that the water cooling
parts are visually inspected every 6 months and a leakage check performed.
Perform the following checks on an annual basis:
● Check that the hose clamps and valve connections are securely seated.
● Perform a visual inspection of the hoses (where these are visible) for tears, cracks or other
We expect an average lifetime of 20 years for the hoses when the specified environmental
conditions are complied with. Values must be taken from the documentation.
You can find further information in the documentation 4BS0698 AL for water cooling systems.
