Contamination of parts and operating fluid by pumped media is possible.
Poisoning hazard through contact with materials that damage health.
In the case of contamination, carry out appropriate safety precautions in order to pre-
vent danger to health through dangerous substances.
Decontaminate affected parts before carrying out maintenance work.
If the turbopump should be shut down for longer than a year:
Remove the vacuum pump from the system, if necessary.
Replace the operating fluid reservoir if necessary.
Close the high vacuum flange of the turbopump.
Evacuate turbopump via the fore-vacuum flange.
Vent turbopump via the venting connection with oil-free, dry air or inert gas.
Close the flange openings by using the original protective covers.
Close further connection ports by using the corresponding protective covers.
Place pump upright on rubber feet.
Store the pump only indoors at temperatures between -25 °C and +55 °C.
In rooms with moist or aggressive atmospheres, the pump must be airproof shrink-
wrapped in a plastic bag together with a bag of desiccant.
Risk of damage to the pump following recommissioning
The operating fluid in the turbo pump has a limited shelf life. The length of its shelf life
is as follows:
● max. 2 years without operation or
● a total of max. 4 years following periods of operation and nonoperation.
Follow the maintenance instructions and inform Pfeiffer Vacuum.
Check turbopump for contamination and moisture.
Clean the turbopump externally with a lint-free cloth and little industrial alcohol.
If necessary, have Pfeiffer Vacuum Service clean the turbopump completely.
If necessary, have the bearings replaced. Take into account the total running time.
Replace the operating fluid reservoir if necessary.
Installation and commissioning in accordance with the operating instructions.
