OperationGuide
InterfaceIntroduction
Conditions that must be met
1. Place on a flat surface.
2. Confirm the voltage and frequency at the outlet match with the vacuum pump
specifications.
3. Confirm the oil level is within the Min and Max level.
4.Remove the air inlet cap(1/4 SAE fitting as shown in the
right image), connect the pumped system(make sure the pipe
fitting is fit with the air inlet fitting). Tighten the air inlet and
make sure the system and hoses are sealed with no leakage.
5. Plug in the power cordand open the exhaust port.

(6) Vacuum Reading Display: Vacuum readings shows when the vacuum of the
system in real-time is below 60000microns. The waiting time for the vacuum
reading is longer for a larger system.
Note: The vacuum reading varies due to the sensor placement dierent. The reading
variances is caused by the uneven air flow during the vacuuming process. The farther
the air from the pump, the higher the air density is thus the vacuum reading is higher.
(7)Leakagelevel: when the vacuum is stable, checktheleakage possibility from 0 to
100 levels. 0 represent uncertain leakage. The larger the number, the greater the
possibility of the leakage.
