7.4 Clean the external surfaces of the pump
CAUTION: CLEANING SOLUTIONS
Risk of damage t
o equipment. Clean the external surfaces of the pump in a well-
venlated locaon. When using cleaning soluons and solvents to clean the pump,
obey the precauons given by the manufacturer. Do not inhale parculates which can
be in the pump.
Do not clean the parts of the pump other than external surfaces. Use of organic
solvents can damage the internal pump components. Do not use abrasive materials
to clean the pump parts.
If the inner side of the pump is contaminated, it cannot be possible to get the necessary
ulmate vacuum performance or the pump-down mes can increase. In this case, return
the pump to our Service Centre for cleaning.
You can use the organic solvent to clean the external surface of the pump. We
recommend you to use non-CFC solvents such as isopropanol or ethanol. Only small
amount of a cleaning soluon is necessary to clean the pump surface.
For environmental reasons, keep wastage of cleaning soluons and solvents to a
minimum.
