Operation Guide
Interface Introduction
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 cordand open the exhaust port.

(5) Estimated End Time: when the vacuum is stable, it shows the estimated job
completion time including holding time.
(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 dierent. 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) Leakage level: when the vacuum is stable, check the leakage possibility from 0 to
100 levels. 0 represent uncertain leakage. The larger the number, the greater the
possibility of the leakage.

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 " " isdisplayed at the top of the screen; When
the temperature decrease within the alarm temperature, the alarm will be cleared, and
the vacuum work continues .If temperature exceeds the oine alarm temperature, the
temperature alarm icon " " will bedisplayed on the top of the vacuum pump screen,
the motor operation will not be aected.
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
-9-
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 aect 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
aecting 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.

Failure
Phenomenon
Cause of Issue
Troubleshooting Method
Low Vacuum
1. Insucient Oil
Add oil between the maximum and minimum
level
2. Pump oil Emulsified, Polluted
Replace with new oil
3. The Oil Inlet Is Blocked or the Oil
Supply is Insucient
Clean the oil inlet and filter
4. Leakage of the Pump System and
Connection
Check the system and the connection to
prevent the leakage
5.
Improper Selection of Pump
Check the size of the pumped container,
recalculate and select the appropriate type of
pump
6. Parts Wear and Tear due to Long
Time Used.
Repair or replace with a new pump
Oil Leakage
1.
The Oil Seal Is Damaged
Replace oil seal
2.
Loose or D
amaged
Tank
Connections
Tighten the screws and replace the O -ring
How to replace the vacuum pump oil
1. Run the pump for about 3-5minutes until it is warmed up to runs out the pump oil.
2. When the pump is running, open the air inlet port at the same time to let the oil flow
back to the oil tank. The pump must stop when replacing the oil.
Stop the pump and open the oil drain plug. Then open the catcher to speed up the
process of oil exhausting.
3. Tilt the pump body to completely drain the residual oil, and tighten the drain plug.
4. Open the catch device and add the new pump oil.
5. Cover the air inlet cap and start the pump to run-check the oil level after one
minute.If the oil level is below the lower limit, slowly add the oil until it reaches the
normal oil level. Finally, screw on the catcher.
1. Power on the vacuum pump.
2. Turn on the Bluetooth function on the mobile phone.
3. Open the “Elitech Tools” AP P.
