Routine maintenance

Periodic and correct maintenance of the vacuum pump will ensure a long operation life and con-
stant performance.
Lubrication
The oil provided with the pump has been specially formulated & manufactured to lubricate vacu-
um pumps; it is special as it features minimum viscosity fluctuation when in use under a wide
temperature range.
The type of lubricant supplied with the pump allows the evacuation of systems operating refrig-
erants. Only working with ROTHENBERGER POE synthetic oil.
The required amount of lubricating oil depends on the size of the pump container specified in the
section "Technical data" and must correspond to the quantity required until the dimensions of
the sight glass are reached.
Replace the oil charge no later than 20 hours of operation.
Oil could be polluted by other oil, humidity, refrigerants, etc. It is mandatory to use oil in perfect
conditions to assure a perfect performance of the pump.
Oil-change
Over-used lubrication oil damages the pumps' mechanism; make sure to replace oil as soon as
it starts to turn cloudy. For conducting the oil-change, the pump must be switched off. For
changing the oil proceed as follows:
 Unscrew the oil drainage plug located on the lower part of the pump
 Check that oil comes out completely from the pump
 Tightly screw the oil drainage plug back on
 Re-fill the pump with oil (see "Filling of oil")
