1.

10.3 Maintenance intervals
To ensure the highest operational reliability of the valves, all wearing parts should
be replaced at longer intervals.
The actual maintenance intervals can only be determined by the user since they
depend on the operating conditions, for instance:
•
daily period of use,
•
switching frequency,
•
type and temperature of the product,
•
type and temperature of the cleaning solution,
•
ambient conditions.
