Package List: 1 x Pressure Gauge 2 x Hoses 1 x Adapter 1 x Storage Case Note: 1. Must be operated by professionals familiar with the vacuum system and industry qualifications.2. Before use, check if the coolant applied in the gauge set is consistent with the system coolant.3. Properly connect the high and low pressure pipes to ensure that the system pressure measured does not exceed the range of the gauge set.4. Clean the connection interface before use to prevent system leakage and foreign matter entry.5. Wear protective gloves and goggles (not included) during use to prevent coolant from contacting the skin and eyes, causing harm to the human body.6. This product is not suitable for areas with explosion proof requirements and coolant containing NH3.7. This product is a precise measuring device. When using and storing, handle with care. In case of accidental falling and impact, carefully check for damage. If necessary, return it to our company for inspection and repair.8. Coolant will pollute the environment, please pay attention to local environmental regulations.9. When not in use for a long time, the battery should be removed, and the scrapped battery needs to be recycled.
