Operation Guide

Conditions that must be met

Place on a ﬂat surface.
Conﬁrm the voltage and frequency at the outlet match with the vacuum pump speciﬁcations.
Conﬁrm the oil level is within the Min and Max level.
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.
Plug in the power cord and open the exhaust port.

Interface Introduction

Main interface

The status bar on top of the page shows the product model, time, Bluetooth status and record status.
1. Model number varies depending on the product models.
2. Bluetooth not connect;Bluetooth connected.
3. During operation, appear when temperature exceeds the upper alarm limit,and appear when temperature below the lower alarm limit.
4. Record: close means no data is recorded. Record: Open means that data is being recorded.
The middle part of the page is the sub-interface button.
1. : Real-time measurement interface
2. : Graph
3. : Vacuum parameter setting
4. : System parameter display and setting
The bottom part is the “Start” and “Stop” button. The motor is off by default after power-on. Click “Start” to start the motor. Button will be locked (within 3 sec); Click “Stop” to stop the motor. Button will be locked (within 10 sec). After the motor stops, in order to prevent frequent start and stop, the button is invalid within 10 seconds.

When the motor starts, the solenoid valve automatically opens instantly. The solenoid valve closes automatically after the motor stops to avoid the oil be suck to vacuum sensor.

Real time measurement interface

Click the “Measure” button on the main interface to enter the real-time measurement interface.

Motor Status: show the current status of the motor.
Motor Temp/Limit: show the surface temperature of the pump chassis and set the alarm temperature.
Oil Temp/Limit: show vacuum pump oil temperature and set the alarm temperature.
Vacuum Status: display the current vacuum value status, "Decrease", "Stable", "Rise", "--".
Estimated End Time: when the vacuum is stable, it shows the estimated job completion time including holding time.
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 different. 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.
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.
Key: return to the main interface.

Graph

Click the “Graph” button on the main interface to view the vacuum change in real time.

When the vacuum value drops below 60000microns, the vacuum change graph is displayed.
The X axis represent time. Y axis represent vacuum. The vacuum value is from 0-60000microns .
Key: return to the main interface.

Other functions

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 "" is displayed 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 offline alarm temperature, the temperature alarm icon " elitech_intelligent_vacuum_pump_svp-7,_svp-9,_and_svp-12-cold_temp.png " will be displayed on the top of the vacuum pump screen, the motor operation will not be affected.

After using the vacuum pump

Close the valve between the pump and the pumped container.
Turn off the power switch on the pump, unplug the power plug, and remove the connecting pipe.
Finally, close the air inlet cap to prevent dirt or ﬂoating particles from entering the pump cavity.

Vacuum Pump SVP-7, SVP-9, and SVP-12 Description

The Elitech Intelligent Vacuum Pump SVP-7, SVP-9, and SVP-12 are designed for durability and reliability, with high-quality components and a robust construction. The pumps feature a compact design, making them easy to install and move as needed. The digital control panel allows for precise pressure control and monitoring, while the automatic pressure control ensures consistent performance. The oil-less design of the SVP-7 and SVP-9 models eliminates the need for regular oil changes, reducing maintenance time and costs. The SVP-12 features an oil-sealed design for even quieter operation and longer lifespan.

Care And Maintenance

Precautions

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.
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 affect the service life of the vacuum pump and the normal operation of the system.
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.
The diameter of the pipe is larger than the inner diameter of the air inlet to avoid affecting the pumping speed.
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 ensure the seal.
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.
It is recommended to clean the catcher once every half year.

How to replace the vacuum pump oil

Run the pump for about 3-5minutes until it is warmed up to runs out the pump oil.
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
Tilt the pump body to completely drain the residual oil, and tighten the drain plug.
Open the catch device and add the new pump oil.
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.

Pros & Cons
