CAUTION

_a

Operation in the wrong direction of rotation can destroy the
vacuum pump in short time.

Prior to starting-up it must be made sure that the vacuum pump is
operated in the proper direction.

Version with three-phase motor:

Determine the intended direction of rotation with the arrow
(a) (stuck on or cast)

“Bump” the drive motor

Watch the fan wheel of the drive motor and determine the di-
rection of rotation just before the fan wheel stops

If the rotation must be changed:

Switch any two of the drive motor wires (three-phase motor)

Connecting Lines/Pipes

In case the suction line is equipped with a shut-off valve:

Connect the suction line

Make sure that the gas discharge (g) is open

Make sure that all provided covers, guards, hoods etc. are
mounted

Make sure that cooling air inlets and outlets are not covered or ob-
structed and that the cooling air flow is not affected adversely in
any other way

Filling Oil

In case the vacuum pump was treated with conservation oil:

Drain the remainders of conservation oil

CAUTION

_a

The vacuum pump is shipped without oil.

Operation without oil will ruin the vacuum pump in short time.

Prior to commissioning it must be made positively sure that oil is
filled in.

The vacuum pump is delivered without oil (oil specification

Ú

page 18:

Oil).

Keep approx. 0.4 litres oil acc. to the table Oil (

Ú

page 18) ready

Note: The amount given in these operating instructions is a guide. The
sight glass (j) indicates the actual amount to be filled in.

CAUTION

_a

Filling oil through the suction connection (h) will result in breakage
of the vanes and destruction of the vacuum pump.

Oil may be filled through the filling port (d) only.

CAUTION

_a

During operation the oil separator is filled with hot, pressurised oil
mist.

Risk of injury from hot oil mist with open filling port.

Risk of injury if a loosely inserted filling plug (d) is ejected.

Remove the filling plug (d) only if the vacuum pump is stopped.

The vacuum pump must only be operated with the filling plug (d)
firmly inserted.

Remove the filling plug (d)

Fill in approx. 0.4 litres of oil

Make sure that the level is at about 75 percent of the sight glass (j)

Make sure that the seal ring is inserted into the filling plug (d) and
undamaged, replace if necessary

Firmly reinsert the filling plug (d) together with the seal ring

Note

: Starting the vacuum pump with cold oil is made easier when at

this very moment the suction line is neither closed nor covered with a
rubber mat.

Switch on the vacuum pump

In case the suction line is equipped with a shut-off valve:

Close the shut-off valve

In case the suction line is not equipped with a shut-off valve:

Cover the suction connection (h) with a piece of rubber mat

Let the vacuum pump run for a few minutes

Shut down the vacuum pump and wait a few minutes

Check that the level is between 50 percent and 75 percent of the
sight glass (j)

In case the level has dropped below 50 percent of the sight glass (j):

Top-up oil

In case the suction line is equipped with a shut-off valve:

Open the shut-off valve

In case the suction line is not equipped with a shut-off valve:

Remove the piece of rubber mat and connect the suction line

Recording of Operational Parameters

As soon as the vacuum pump is operated under normal operating
conditions:
