●
Connect the discharge line
Installation without discharge line:
◆
Make sure that the gas discharge (c, 155) 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 Oil).
●
Keep approx. 1.0 litres oil acc. to the table Ú Oil ready
Note: The amount given in these operating instructions is a guide. The
sight glass (m, 83) indicates the actual amount to be filled in.
CAUTION_a
Filling oil through the suction connection (d, 260) will result in
breakage of the vanes (r, 22) and destruction of the vacuum pump.
Oil may be filled through the filling port (l, 88) 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 (l, 88) is ejected.
Remove the filling plug (l, 88) only if the vacuum pump is stopped.
The vacuum pump must only be operated with the filling plug (l,
88) firmly inserted.
●
Remove the filling plug (l, 88)
●
Fill in approx. 1.0 litres of oil
●
Make sure that the level is between the MIN and the MAX-mark
-
ings of the sight glass (m, 83)
●
Make sure that the seal ring (89) is inserted into the filling plug (l,
88) and undamaged, replace if necessary
●
Firmly reinsert the filling plug (l, 88) together with the seal ring
(89)
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 (d, 260) 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 the MIN and the MAX-markings of
the sight glass (m, 83)
In case the level has fallen below the MIN-marking:
◆
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
Version with exhaust filter pressure gauge:
◆
Read the scale of the exhaust filter pressure gauge and record
it as reference for future maintenance and troubleshooting

Operation Notes
Use
CAUTION_a
The vacuum pump is designed for operation under the conditions
described below.
In case of disregard risk of damage or destruction of the vacuum
pump and adjoining plant components!
Risk of injury!
The vacuum pump must only be operated under the conditions de-
scribed below.
The vacuum pump is intended for
–
the suction
of
–
air and other dry, non-aggressive, non-toxic and non-explosive
gases
Conveying media with a higher density than air leads to an increased
thermal and mechanical load on the vacuum pump and is permissible
only after prior consultation with Busch.
Permissible temperature range of the inlet gas: see “Oil”, “Ambient
temperature range”
In case the vacuum pump is equipped with a gas ballast (optional) wa
-
ter vapour within the gas flow can be tolerated within certain limits
(à Conveying Condensable Vapours). The conveyance of other va
-
pours shall be agreed upon with Busch.
The vacuum pump is intended for the placement in a non-potentially
explosive environment.
Version with float valve (j, 200) and oil return line:
The vacuum pump is thermally suitable for continuous operation.
Version with oil return valve (f, 280):
The vacuum pump is thermally suitable for continuous operation (ob
