Note
Checking the hose lines
The inspection intervals depend on the prevailing ambient conditions.
The following points should be noted for the coolant hoses:
• Damage through abrasion points
• Embrittlement (e.g. forming of cracks)
• Leaks
• The hose slipping out of the coupling
• Deformations that do not comply with the natural shape of the hose (e.g. separation of
layers and blistering)
• Exceeding the storage and use times
In accordance with the accepted rules and standards, we recommend a testing cycle of
five years with the appropriate test pressure (twice the operating pressure).
