Fitting accessories
Either a water or air cooling facility and a purge gas and venting valve can be
fitted to the pump.
Moreover, the frequency converter may be fitted beside or underneath the
pump.
See Fig. 2.1 to 2.3
When fitting the accessories note the following:
■
For fitting, place the pump
with the protection cap in place
on its high
vacuum flange.
■
Fitting the water cooling: Unscrew 2 screws and bend the cooling coil
cautiously a little bit open. Mount it to the pump and fix the 2 screws.
The cooling water may be connected radially or axially to the connecting
piece of the cooling coil; see Fig. 2.1. Blank off the unused G 1/8” threads
using the screw-in stoppers and gaskets supplied.
