Inlet isolation valve
(accessory)
Exhaust of corrosive, reactive, flammable, pyrophoric or oxidizing process
gases may result in severe injury or death.
Always connect the pump exhaust to an exhaust extraction system.
Ensure that all components in the exhaust pipeline have a maximum pressure
rating which is greater than the highest pressure that can be generated in
your system.
Make sure that any vacuum accessories connected to the inlet of the pump
can withstand a negative pressure of 1
· 10
3
hPa, with reference to the
atmospheric pressure.
At the pump inlet
To get the best pumping speed, ensure that the vacuum line is the
minimum length possible and has an internal diameter not less than
the inlet connection of the pump.
This accessory avoids a sudden reverse flow of gas to the chamber
when the pump is stopped.
Connect the valve directly on the pump inlet flange using
connecting accessories.
Connect the electrical cable to the electronic cabinet inside the
frame (see
D 10
).
If the valve must be remote controlled, see
C 70
.
