7.3 Priming the Vacuum Pump
•
Priming of the vacuum pump requires that the connecting tube provided is securely
(airtight sealed) placed between the vacuum pump and the vacuum oven.
•
The oven door should be securely shut and the door handle secured in a closed position
(this will prevent air from entering the chamber by causing the hole in the rubber plug
and the hole in the pipe core to be 180 ° out of phase).
•
Power to the vacuum pump should be turned on and then the vacuum valve should be
closed by turning the handle clockwise 90°during processing.
•
To stop the process, reduce the vacuum in the chamber -0.1Mpa before turning off the
vacuum pump. This will ensure that no engine oil from the vacuum pump will be drawn
into the chamber.

a 5 second self-test is completed, the temperature controller will automatically enter the
