10.1 Shutting down for longer periods
Before shutting down the vacuum pump, observe the following instructions to adequately protect the in-
terior of the vacuum pump (suction chamber) from corrosion:
Procedure for temporary vacuum pump shutdowns
1. Allow the vacuum pump to run on for 5 to 10 minutes with the vacuum connection open to allow
any condensate that may be present to be removed from the vacuum pump.
2. If media has entered the vacuum pump that may attack the pump materials or lead to deposits,
clean the inside of the pump heads.
Procedure for longer vacuum pump shutdowns
1. Disconnect the vacuum pump from the vacuum system.
2. Remove the vacuum pump from the vacuum system if necessary.
3. Seal the vacuum connection with the original sealing plugs.
4. Store the vacuum pump in dry, dust-free rooms, within the specified ambient conditions.
5. Pack the vacuum pump together with a drying agent in a plastic bag, and seal the vacuum pump
airtight if it is to be stored in rooms with damp or aggressive atmospheres.
