▪ Leak test the system aer installaon is complete and seal any leaks found to
prevent leakage of hazardous substances out of the system and leakage of air into
the system.
▪ Mechanical liing equipment should be aached to the liing eye on the pump.
▪ Loose slings should not be used to li the pump.
4.2 System design consideraons
WARNING:
Ensure the exhaust pipeline cannot become blocked. If an exhaust isolaon valve is
ed, ensure the pump cannot be operated with the valve closed.
Consider the following points when designing the pumping system:
We recommend the use of a foreline vacuum isolaon valve to allow the pump to warm
up before pumping condensible vapours or if the vacuum needs to be maintained when
the pump is not running.
Avoid high levels of heat input into the pump from the process gases, otherwise the
pump may overheat and cause the thermal overload device to open.
If the pump is used in a high ambient temperature with high gas throughput, the pump
body temperature may approach 65 °C. We recommend the use of addional guarding
to prevent contact with hot surfaces under these condions.
Dilute ammable mixtures to safe concentraons by providing an inert gas diluon
purge. Contact our applicaons team for further advice on diluon requirements if
required.
