Troubleshooting
The Pump Does Not Start After Switching The Power On
Check the power cord and ensure it is plugged in.
Check whether or not the system has higher negative pressure. This can be judged from the vacuum gauge. If
negative the pressure is bigger than -0.05MPa the pump cannot start. The pump will work again as long as
release the atmospheric pressure inside the system and back to regular level.
The Pressure Declines Rapidly
Check whether or not the liquid, volatile solvent vapours or particles are inhaled into the pump. If so, please pull
out the ”IN” connection pipe and then switch the power on, and make pump working without loading for about
10 minutes to dry up or blow out the impurities inside the pump.
