6.0 Installation
6.1 The mechanical seal type MSS is installed in the mixer in accordance with the ins-
tructions from the machine manufacturer and with consideration to the following
recommendations.
The machine to take the mechanical seal type MSS must be earthed in accor-
dance with the applicable regulations for electrical installations (e. g. VDE rules)
to conduct away any electrostatic build-up and so prevent spark formation.
Parts of the mechanical seal, which needs to be entered during assembly works,
needs to be secured against slipping, stumbling or falling (e. g. by holding
devices).
Installation of the mechanical seal type MSS on the machine may take place
during machine breakdown only.
!
The areas for the clamp-connections must remain free of grease, otherwise the
adhesive force will become inadequate for correct functioning.
!
There are two basic models of the MSS seal, piloted, see Figure , page 9, and
NON-Piloted, see Figure 3, page 13.
