Troubleshooting
Even carefully designed and manufactured technical systems that are operated
properly, may experience malfunctions. The table below provides an overview of
possible problems that may occur during the operation of system separators and
indicates the causes and their elimination.
Attention!
Short-term, undefined water leakage at the discharge valve of the sys-
tem separator does not represent a malfunction but is a normal control behaviour
of the system separator caused by pressure fluctuations on the inlet side in the
water supply system.

In case of disturbances, e.g. permanent water leakage at the discharge
valve, proceed as per the checklist below:
