Before use, check if the freezing medium compatible with the system matches the freezing medium of the Gauges​ set. 2. Properly connect the high and low pressure hoses to ensure that the system pressure being measured does not exceed the Gauges​ set's range. 3. Clean the connection interfaces before use to prevent air leakage and foreign matter from entering the system. 4. Wear protective gloves and goggles during use to prevent contacting with freezing medium on skin and eyes, which may cause harm to the body. 5. This product is not suitable for explosion proof areas or ammoniated refrigerants. 6. This product is an accuracy measuring instrument, handle with care during use and storage. If accidentally dropped or damaged, carefully inspect for any issues. If necessary, send back to the company for repair. 7. Refrigerants can pollute the environment, please be aware of local environmental regulations. 8. This product contains a built in Li battery, recharge periodically if not used for a long
