As required, connect the inlet of the pump to the vacuum system, and the outlet of the pump
to the inlet of the backing pump. The inlet and outlet flanges of the pump are standard ISO
flanges.
All BSJ600LC and BSJ1200LC pumps have two alternative outlet position: on the underside
of the pump and the side of the pump. Users can choose to use it as needed. The pump is
supplied with the side outlet and the bottom outlet is blocked. If the user does not wish to use
the side outlet, remove the blind plate and O-ring from the outlet below the pump and
reinstall the blind plate and O-ring on the side outlet flange.
Pay attention to the following when connecting the pump to the vacuum system.
1. Move the pump to the required position and ensure that it is level and secure.
2. In order to get the best pumping speed, ensure that the pipeline connected to the pump
inlet is as short as possible, and the inner diameter of the pipe is not less than the
diameter of the pump inlet.
3. Pipelines connecting the pump to the vacuum system should be connected by soft pipe
to reduce vibration and stress.
4. In dusty applications, low-impedance inlet filter should be used to minimize abrasion in
the pump.

Operation
4.1 Operational safety
WARNING
Ensure that the cooling air flow through the pump and motor is not
restricted. If the air flow is restricted during pump operation, the pump and
motor temperatures will exceed their normal temperature.
Abnormal temperature can reduce pump reliability and risk of explosion.
During the operation of the pump, it is forbidden to touch the surface
directly by hand to avoid being burnt.
WARNING
Do not operate the pump when the inlet or outlet is in open to atmosphere.
If not, fingers or other parts of the body may get trapped and may be injured
by the rotating pump.
