can produce dangerously high pressures. If the trap becomes saturated it should be disconnected
from the system, drained and cleaned. An increase in pressure in the vacuum system will normally
indicate that the trap has become saturated. To clean the trap, remove the trap from the system, allow
the trap to warm up and rinse off the condensate with a suitable solvent in a fume hood. Thoroughly
clean and dry the trap before reinstalling in the system.
5.11 Side Panel Fitting Port
Some applications call for a gas purge using a clean dry gas such as nitrogen. An external gas supply
can be routed into the gas ballast assembly using that port.

5.12 Closing down
A few simple precautions are necessary before performing a pump shutdown.
1. If a gauge is connected to the system, first isolate the gauge, then turn off the power to the
pump and open the system to the atmosphere.
2. If condensable media have been pumped, the vacuum pump must be run after pumping
with the gas ballast valve open and the intake pipe closed.
3. If the vacuum pump is not going to be used for a sometime after pumping aggressive or
corrosive media, or if it not going to be used for a long time, then proceed as follows:

If the pump oil is contaminated and the pump is going to be stored for a prolonged
period, the oil should be changed before the pump is stored. Even if a pump is
stored for a long period with oil initially in good condition, check the oil when the
pump is restarted, and change the oil if necessary.

Close connecting ports with a rubber stopper or other suitable cover to protect the
pump against contamination. An intake screen is furnished to prevent loose particles
from entering.
