Oil filling on vacuum pump NS 0070 C
Oil filling on vacuum pump WY 2000 C
NOTE : The quantity of oil specified in the installation handbook is of
informative nature only. Check the oil level with the help of the various
oil sight glasses (OSG) on the vacuum pump.
CAUTION
Before you change the type of oil, make sure that the new type is
compatible with the old type. If necessary, flush the vacuum pump.
l Unscrew the oil filler cap (OFP)
l Fill in oil
l
Make sure that the oil level lies between the MIN and
MAX-markings on the oil sight glasses
l Make sure that the seals of the oil filler cap are not damaged.
Replace them if necessary
l Screw on the oil filler cap hermetically tight
NOTE : It is easier to switch on the vacuum pump with cold oil when
the intake line is not closed or when the intake flange is not covered by
a rubber plate.
l Start the vacuum pump
If the intake line is equipped with a shut-off device:
u
Close the shut-off device
If the intake line is not equipped with a shut-off device:
u Place a rubber plate on the intake flange
l
Let the vacuum pump run for a few minutes
l Stop the vacuum pump and wait a few minutes
l Make sure that the oil level still lies between the MIN and MAX
markings on the oil sight glasses
If the oil level is below the MIN marking:
u Fill in more oil
If the intake line is equipped with a shut-off device:
u Open the shut-off device
If the intake line is not equipped with a shut-off device:
u Remove the rubber plate from the intake flange and connect
the intake line to the intake flange
CAUTION
In case of a vacuum pump filled with oil, make sure that by lifting
the inclination angle of the vacuum pump do not exceed 5° from
the horizontal. In case of too high inclination (>5°), risk of oil leak
within the work area.
l Make sure before every transport using the appropriate lifting
mean that the inclination of the vacuum pump is less than 5°.
CAUTION
The vacuum pump must remain in a horizontal position when it has
been filled with oil.
Filling in cooling liquid
The COBRA DS 0080-2000 G vacuum pumps are generally
dispatched with cooling liquid already in the vacuum pump. Before
vacuum pump first startup, control the cooling liquid level. In the
event of absence of one or the other of these lubricants, please carry
out the filling (see the chapter “Cooling liquid types” for information
on the recommended cooling liquids).
l Prepare the quantity of cooling liquid specified in the table “Coo-
ling liquid quantity”

NOTE : The quantity of cooling liquid specified in the installation
handbook is of informative nature only. Respect the procedure of filling
the cooling liquid. Check the level of the cooling liquid at the liquid
level indicator located at the filler or with a measuring scale. The level
of the cooling liquid in the expansion tank may never exceed 5 mm
seen from the bottom of the vessel.
l Unscrew filler cap (CLF) of cooling liquid on the expansion vessel
l Open the purge valve (CLV)

l Fill in the cooling liquid through the filler opening until the liquid
starts running out the purge valve (CLV)
l Stop filling in cooling liquid
l Close the purge valve (CLV)
l Fill in more cooling liquid through the filler opening until the level
of the liquid is 5 mm above the bottom of the expansion vessel
l Check the level of the cooling liquid with the measuring scale loca-
ted under the filler. The level of the liquid must not lie above the
bottom marking.
