WORKING MODES:
The system comes with three common working modes: refrigerant pressure mode, 
vacuum percentage mode,leak detection mode. The interfaces of different working 
modes are as follows:
REFRIGERANT PRESSURE MODE
It's used for charging the refrigeration system with refrigerant, as well as real-time displaying curent vacuum pressure, temperature, and type of refrigerant
VACUUM PERCENTAGE MODE
It's used for charging the refrigeration systems.
Real-time display of current vacuum level.
LEAK DETECTION MODE
It's for detecting pressure leaks in refrigeration systems, with real-time display of current vacuum pressure, leak pressure and work time.
ROTARY SWITCH OPERATION INSTRUCTIONS:
* High and low pressure gauge selection
Blue arrow“LOW”for low pressure rotary switch,red arrow“HIGH” for high pressure 
rotary switch.
 * digital Single manifold power on/off
90 degree limit rotary switch,arrow pointing to ON /OFF,red and blue button are all 
close in clockwise and open in anti-clockwise.
 * 2-Valve digital manifold power on/off

clockwise and op
MAINTENANCE AND MAINTENANCE
1. Please operate according to the requirements of operating instructions or the 
guidance of professional personnel.
2. The digital gauge should be keept clean, the display screen should be bright and 
clear, so that the data on the display screen clearly.Use slightly alkaline detergent 
or soapy water to wash the case and connector.
3. The pressure gauge is perishable goods,need to checking regularly to ensure its 
accuracy.
4. Handled gently , to prevent shock and fall.
5. After use, please close all the button, to improve the service life .
6. Plug the joint when not use,to prevent foreign body from entering, clean and 
replace regularly refrigerant tube, remove dirt and impurities in valve.
