8.2 Connection to the System
•
For the pump’s installation site and positioning, consider convenience of access to the
connections for installation, maintenance, disassembly, and electrical connections as
well as good ventilation clearance.
•
Ensure the power supply is disconnected prior to commencing connections, repairs, or
maintenance activities.
•
Set up on a flat, stable, and firm surface
•
Ensure not to obstruct the ventilation of the motor to avoid fire and burn hazards caused
by abnormal temperature rise.
•
The pump must be operated at an ambient temperature between 10 - 40
℃
•
The length of the connecting line between the pump and the vacuum system needs to
be as short as possible.
•
The diameter of the connecting line is required to be the same as that of the intake port
•
The exhaust line should be laid so that it slopes down to prevent condensate from back
streaming into the pump and contaminating the oil.
•
Drain the oil from the exhaust line periodically to avoid blockage of the exhaust line.
If the exhaust line slopes up, the installation of a condensate trap is necessary.
•
Check for connection leakage between the pipe and the flange.
•
Vacuum sealing tightness is essential to achieve ultimate vacuum.
•
Check the oil level prior to start up and each operation before running.
•
Do not operate the pump without oil or if the oil level is low. This will result in pump
failure.
•
Check there is no oil leakage from the pump to prevent potential slip hazards caused
due to oil spillage.
•
Running the pump in an incorrect rotation of the motor may cause pump failure.
•
Ensure the gas flow at the exhaust port is not blocked or restricted in any way.
Check the exhaust line is not obstructed by deposits before start-up.
•
The exhaust pressure shall not be 1.15 bar higher than the absolute pressure (relative
pressure 0.15 bar) but not be lower than atmospheric pressure
•
Oil must be added as outlined prior to start-up of the Pump.
•
The exhaust passage must be unimpeded during operation. Ensure the gas flow
from the exhaust port is not blocked or restricted in any way.
•
To pump condensable gases only use the pump to do so if a gas ballast is installed.
•
When pumping a small amount of dust and condensable gases, the installation of
corresponding filters is required. Without filters a sharp drop in performance or pump
failure may occur.
