Other functions
1. Temperature alarm: When the oil temperature or motor chassis temperature exceeds
the upper limit alarm temperature set by the APP, the motor and solenoid valve are
closed, the temperature alarm icon "
the temperature decrease within the alarm temperature, the alarm will be cleared, and
the vacuum work continues . If temperature exceeds the o ine alarm temperature, the
temperature alarm icon "
the motor operation will not be a ected.
5. After using the vacuum pump
1. Close the valve between the pump and the pumped container.
2. Turn o the power switch on the pump, unplug the power plug, and remove the
connecting pipe.
3. Finally, close the air inlet cap to prevent dirt or floating particles from entering the
pump cavity.
Care And Maintenance
Precautions
1. When the vacuum is started, the air pressure is relatively high and the pump
exhaust volume is large, thus oil mist will be overflowing with a large amount of
gas. This is a common phenomenon for a rotary vane vacuum pump.
When the vacuum drops to a very low level, the pump exhaust volume is small,
and there will be no oil mist. Therefore, user should regularly monitor the oil level
via the oil window to avoid running out of oil.
2. During operation, storage and transportation, keep the vacuum pump clean to
prevent pollutants such as water, mechanical impurities,etc.from entering the
pump so as not to a ect the service life of the vacuum pump and the normal
operation of the system.
3. The oil in the pump should be drained if it is not used for a long time. Store the
pump in a dry and clean environment.
4. The diameter of the pipe is larger than the inner diameter of the air inlet to avoid
a ecting the pumping speed.
5. Check the tightness of the pipe connection to prevent leakage. Recommend using
the vacuum grease on the connection and clamp it with a clamp to ensurethe seal.
6. Do not use the pump to pump out gases which contain high level of oxygen,metal
corrosive and explosive gases. In addition, do not pump in any gases that react
with pump oil and containing large amount of water vapor.
7. It is recommended to clean the catcher once every half year.
