WARNING:
Do not operate the dry pumping system with the exhaust pipeline blocked. If the
exhaust pipeline is blocked, the dry pumping system can generate exhaust
pipeline pressures of up to 10 bar (10 x 10
5
Pa). Note that a pressure spike up
to a maximum 15 bar (15 x 10
5
Pa) can be generated in the exhaust pipeline for
less than 0.5 seconds if the inlet is instantaneously exposed to atmospheric
pressure when the pump is running and the exhaust is blocked.
WARNING:
Do not touch the pump exhaust and check-valve (if fitted) while the pump is
running since the temperatures of these parts cause burns. These parts will
remain hot after the pump has stopped.
CAUTION:
The dry pumping systems have a maximum continuous exhaust line pressure
limit. Operation above the limit may damage the pumping mechanism.
The light duty dry pumping systems do not have an exhaust pressure sensor.
The maximum continuous exhaust line pressure of these dry pumping systems
should not exceed 0.2 bar(g).
For all pumps, it is your responsibility to provide an exhaust system with
suf
ficient conductance to ensure the exhaust pressure limit is not normally
exceeded.
CAUTION:
Use a catchpot to prevent the drainage of condensate back into the dry
pumping system. Condensate that drains back into the dry pumping system
could damage the pump.
Do not reuse any O-ring or O-ring assembly and do not allow debris to get into
the dry pumping system during installation.
When connecting the dry pumping system to the vacuum system, take note of
the following:
▪ To get the best pumping speed, ensure that the pipeline which connects the
vacuum system to the dry pumping system is the minimum length possible
and has an internal diameter not less than the system inlet port.
▪ Ensure that all components in the vacuum pipeline have a maximum pressure
rating which is greater than the highest pressure that can be generated in the
dry pumping system.
▪ Incorporate flexible pipelines in the vacuum pipeline to reduce the
transmission of vibration and to prevent the loading of coupling joints. We
recommend using our braided flexible pipelines. The pipelines should be rated
for 1
10 °C.
▪ Adequately support vacuum/exhaust pipelines to prevent the transmission of
stress to pipeline coupling joints.
