COMBI of the procedure. The COBRA BC 0601 G pumps are a combination of a screw vacuum The allowed maximum inlet gas temperature depends on the inlet pump NW 0090 A (DP) and a Roots vacuum pump WY 0700 D (MB) pressure and the type of gas: the lower the inlet pressure (Pa), the higher the drawn gas temperature (TGas) can be.
The COBRA BC 0601 G vacuum pumps are COBRA NW screw of these lubricants, please carry out the filling (please refer to the vacuum pumps with cooling water and nitrogen circuits. various chapters of filling). Do not forget to connect the cooling water supply before the first startup.
It is vital that these installation and maintenance instructions are read and understood before the vacuum pump is used. If you have any doubts, please contact your local Busch representative. Safety Information The vacuum pump has been designed and manufactured in accordance BC 0601 G with the latest technical and safety standards.
CAUTION Only authorized personnel may carry out any dismantling on the vacuum pump. Before work begins, the operator of the vacuum pump must fill in a form or a “Declaration Regarding Contamination of Vacuum Equipment and Components” that provides information on possible dangers and appropriate measures.
NOTE: VCI is the abbreviation for “volatile corrosion inhibitor”. The NOTE: 1° (german degree = 1° dGH) = 1,78° (french degree) = 1,25 e VCI molecule is an organic corrosion inhibitor in the vapour phase.

Discharge connection In the case of long discharge lines the line cross-section should be larg er than the discharge flange to prevent a drop in the performance of the vacuum pump. If you have any doubts, contact your Busch representative. CAUTION Cooling water connection Do not put hands into the outlet aperture.
Oil quantity [Liter] 0,12 Stop the vacuum pump and wait a few minutes Busch VF 250, Art. No. 0831 131 400 (0,5l Oil type Make sure that the oil level still lies between the MIN and MAX ≅ 1 kg) (Busch YLC 250 B)
CAUTION Make sure that the system does not leak The COBRA BC 0601 G vacuum pumps could be delivered If the system is equipped with a solenoid gate valve at the intake: without oil, without cooling water. Operation without oil will result in damage to the vacuum pump!
(Busch) Inspect the vacuum pump for leaks of cooling water - if there are leaks, repair the vacuum pump (Busch) CAUTION Monthly: Before maintenance work is started, a safety area of at least In the case of operation in a dusty environment: 610 [mm] around the machine must be set up.
