Once operating voltage has been supplied and
on successful completion of the self-test on the
TC 600, the turbopump and any possible
connected backing pump is started.
Venting Release (Optional)
Automatic venting:
CAUTION
4.6. Shutting Down For Longer Periods
If aggressive or hazardous gases are pumped
there is a danger of personal injury resulting
from coming into contact with process gases.
Before removing a turbopump from the system,
first:
– Vent the turbopump with a neutral gas or dry air.
– Ensure that there is no residual process gas in the system
nor in the feeder lines.
If the turbopump is to be shut down for more than a year:
➡
Remove turbopump from the system.
➡
Change the lubricant reservoir (see Section 7.1.).
Lubricant TL 011 should not be used when
there have been no operations for 22 yye
ea
arrss..
➡
Close the high vacuum flange and evacuate the turbopump
via the fore-vacuum flange.
➡
Vent turbopump via the venting connection with nitrogen
or dry air.
➡
Close fore-vacuum and venting connection by blank flan-
ging.
➡
Place the pump vertically on its rubber feet.
➡
In rooms with moist or aggressive atmospheres, the
turbopump must be air-sealed in a plastic bag together
with a bag of dessicant, e.g silicagel.
If the pump has been shut down for 33 yye
ea
arrss, the
bearing must be changed (please contact
Pfeiffer Vacuum Service).

Motor, Turbopump
When the pumping station is switched on and once the self
test has been successfully completed (duration approximate-
ly 10 seconds), the turbopump is set in operation.
During operations, the turbopump can be switched on and off
while the pumping station is switched on.
Thereby the turbopump will not be vented.
