In case of power failure during operation,
turn the pump off for safety reasons.
2. Description
The rotary-vane pump 1012855 must only be
used in vacuum experiments to depressurize
vacuum containers. It is not designed for com-
mercial use.
The pump is a high performance, compact, one-
stage, oil-sealed rotary vane pump. It is pro-
tected against thermal overload and equipped
with an exhaust filter to reduce oil mist, a ma-
nometer and a ventilation valve.
For reasons of transport the pump is delivered
with no oil in the reservoir. In the package you
should find a bottle of oil, sufficient for the first
filling.
The pump is equipped with a voltage selector
switch (refer to fig. 1), so that it can be operated
with mains voltages of 110 V or 230 V plus or
minus 10 %.

4.1 General information
•
After unpacking, please place all parts of the
package (bags, boxes, polystyrene sides)
away from the reach of children.
•
Check the presence of the data label on the
hosing. If the label is not present, do not use
the pump and inform the supplier.
•
In case you need to send back the pump to
the distributer (e.g. repair) drain the oil.
•
For the disposal of the oil adhere to the local
regulations.

4.2 Before operating the pump
•
Place the pump horizontally on a stable
support.
•
Do not connect the pump yet to the mains
voltage.
•
Check that the voltage selector switch is set
to the local mains voltage and ensure that
the power switch is in the OFF position be-
fore connecting the pump to a power source.
•
Remove the oil fill cap and add oil until it
shows at the bottom of the sight glass. Refer
to the technical data for the correct oil ca-
pacity of the pump.
•
Screw back the oil fill cap, remove the cap
from the hose nipple and open the stopcock.
•
Turn the motor switch to ON position.
•
When the pump runs smoothly put the cap
back onto the hose nipple and close the
stopcock. This may take 2 to 30 seconds
depending on the ambient temperature.
•
After the pump operates for approximately
one minute, check the sight glass for proper
oil level, which should be aligned with the
sight glass oil level line. Refill oil if neces-
sary.
Note: Insufficient oil filling will result in poor vac-
uum performance. Excessive oil can result in
overflowing of oil from the exhaust fitting.

4.3 To shut off the pump after use
To prolong life span of the pump and a smooth
start-up, these procedures to shut off the pump
should be followed.
•
Close the stopcock.
•
Remove the hose from the hose nipple.
•
Switch off the pump and open the stopcock for
