The Vacuum Pump V-700/710 can be used together with the Vacuum Module V-802 LabVac as a
laboratory vacuum system. If the pump is used without a Vacuum Module V-802 as a laboratory
vacuum system it will automatically reduce the suction power after one hour of operation and start
working in the ECO
2 Mode (see also chapter 6.1.5).
