WARNING
Health hazard through poisoning from toxic contaminated components or devices
Toxic process media result in contamination of devices or parts of them. During maintenance work,
there is a risk to health from contact with these poisonous substances. Illegal disposal of toxic sub-
stances causes environmental damage.
►
Take suitable safety precautions and prevent health hazards or environmental pollution by toxic
process media.
►
Decontaminate affected parts before carrying out maintenance work.
►
Wear protective equipment.

8.2 Recommissioning
NOTICE
Risk of damage to the turbopump as a result of operating fluid aging after recommissioning
The shelf life of the operating fluid of the turbopump is limited. Aging of the operating fluid may lead
to the failure of the ball bearing and cause damage to the turbopump.
►
Pay attention to when the operating fluid must be changed:
●
after maximum 2 years without operation,
●
after maximum 4 years combined operation and downtimes.
►
Observe the maintenance instructions and inform Pfeiffer Vacuum Service.
