To build up vacuum:
1.
Remove the vacuum valve cap.
2.
Connect the hand pump to the
valve and pump several times
until it reaches the target
vacuum level.
3.
After the target vacuum level is
reached, i.e. steady green light.
Attention: After the target vacuum is
reached, i.e. steady green light, attach
the cap back to the vacuum valve
.
4.
It is recommended to leave the housing
for at least 20mins to ensure it is sealed.
If the LED light changes from steady
green light to rapidly flashing yellow
light, that means there is a leakage and
please check every o-ring and conduct
the vacuum test again.
