INSTRUCTIONS FOR USE
Routine maintenance
Periodic and correct maintenance of the vacuum
pump will ensure a long operation life and constant
performance.
Lubrication
The oil provided with the pump has been specially
formulated & manufactured to lubricate vacuum
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
with CFC, HCFC and HFC refrigerants. Working with
ROTHENBERGER POE synthetic oil is also feasible.
Both ROTHENBERGER oil types available after order.
Volumes to be filled into the pumps are specified in
section 1.1. Replace the initial oil charge no later than
150-200 hours of operation; further replacements
should be carried out every 600 hours of correct
usage.
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”)
WARNING: Do not pollute the environment by
spilling oil; the lubricant oil is a special waste and
must be disposed of according to relevant local law
/ guidelines in force.
Extraordinary maintenance / repair
Conduct extraordinary maintenance or repair
whenever serious faults occur such as overheating,
poor ultimate vacuum, persistent loudness / noise,
blocked pump or any other irregular functioning.
In that case, the pump needs to be disassembled,
parts need to be cleaned, repaired or replaced.
Only qualified service staff shall carry out such
maintenance or repair work; otherwise the warranty
will be void. For any information please contact our
Service-After-Sales.
