15.4 Cooling water characteristics
The characteristics below concern only the magnetically levitated turbomolecular pump. This pump is
associated with a backing pump. To ensure the effective operation of the application:
1. Comply with the most restrictive characteristics for the installation.
2. Make sure the water coming from the equipment does not freeze.
