connection is secure and reliable, without the risk of tripping over others.
• After the installation work is completed, a system leak test is carried out, and it is found
that the leak should be blocked to prevent dangerous substances from leaking out of the
system and air entering the system.
3.2 System requirement
Design the pumping system to consider the following points:
• Suitable backing pumps must be used: see sections 2.1 and 2.2.
• The pump must be mounted on a firm, level surface.
• The vacuum pipeline must be adequately supported to prevent stress passing to the
pipeline joint.
• If necessary, install a hose in the system pipeline to reduce the transmission of vibration
and prevent the joint from being stressed. If a hose connection is used, it must be
ensured that the maximum pressure rating of the hose used is higher than the highest
pressure the system can produce.
• The intake air temperature must be limited to the system temperature class.(if necessary)
• If dangerous substances will be pumped, ensure that the design incorporates all suitable
safety precautions.
• When the pumping system is shutting down, the user must purge with an inert gas to
dilute the dangerous gases to safe concentrations.
• If the pump is installed in a new system, ensure that all preliminary pipelines have been
installed and a suitable base for the pump has been prepared before starting installation.
Check of the following supplies and facilities are available for connection to the pump:
• Power supply.
• Cooling water supply and return.
• Exhaust extraction system.
• Inlet mesh (if necessary).
3.3 Unpack and inspect
WARNING
Use suitable lifting equipment to carry the pump.
Otherwise, it may cause personal injury or Pump damage.
The steps for unpack and inspect are as follows:
