2.6 Safety information for the user/operator

▪

Fit protective equipment (e.g. contact guards) supplied by the operator for hot,
cold or moving parts, and check that the equipment functions properly.

▪

Do not remove any protective equipment (e.g. contact guards) during operation.

Higher leakage may occur especially in the running-in phase. The leakage must
be drained off in a controlled way

2.7 Safety information for maintenance, inspection and installation

▪

Modifications or alterations of the mechanical seal require the manufacturer's
prior consent.

Use only original spare parts or parts/components authorised by the
manufacturer. The use of other parts/components can invalidate any liability of
the manufacturer for resulting damage.

The operator ensures that maintenance, inspection and installation are
performed by authorised, qualified specialist personnel who are thoroughly
familiar with the manual.

▪

Only carry out work on the mechanical seal when the shaft is not rotating.

For mechanical seals installed in pump sets:

▪

The pump (set) must have cooled down to ambient temperature.

▪

Pump pressure must have been released and the pump must have been drained.

▪

When taking the pump set out of service always adhere to the procedure
described in the manual.

▪

Decontaminate pumps which handle fluids posing a health hazard.

▪

As soon as the work has been completed, re-install and re-activate any safety-
relevant devices and protective devices. Before returning the product to service,
observe all instructions on commissioning.
