2.3 Vacuum System Connection
Please tear down the sealing element(plastic cap) before connection
Please keep the sealing element for storage purpose
Please make the connection by using the clamp and center ring
Please always keep the intake line clean and tidy, or it will have a strong impact on vacuum degree
The connecting lines between vacuum pump and vacuum system should be as short as possible
If the exhaust gas should be collected,then the exhaust line should be as big as possible and clean and tidy, to
avoid explosion
If no exhaust line,then we suggest to install a discharge filter or oil mist filter
Do not operate the pump with sealed exhaust port,to avoid explosion
The exhaust line should preferably be installed with a downward slope so as to prevent condensate from
flowing back into the pump. But if not workable, then we suggest to install a cold trap
2.4 Electrical Connection
The electrical connection should be handled by the skilled electrician, and obey the local regulation such as
EN60204-1
Please always cut off the power supply during connection,and also install the integrated control system to avoid the
malfunction of the main power. And obey the safety instruction 0.2
2.4.1 Single Phase(220V) Motor
Please choose the suitable fuse wire according to the nameplate on the motor, and equip with the suitable socket.
The motor is equipped with the overload protection device. So when the motor stopped because of overheating,
please shut down the power if you will have any operation on the pump, because the motor will be start
automatically once it is being cool down.

The pump is supplied without any accessories of electrical connection. Please using the appropriately rated cable
and a suitably rated motor protection switch, the value set on the motor protection switch must correspond to the
