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.
