Quality control: The vacuum pump has undergone 100% quality testing before leaving the factory to ensure the complete performance of each product. Friendly Note: A small amount of oil which is injected in the machine during the factory quality test may leak out in transit, which do not affect usage effect. Method for checking the leakage of the vacuum pump: Method 1: Connect the vacuum pump inlet port with a vacuum gauge. Method 2: Tighten all three air intakes, turn on the machine, and after a few minutes, check for oil mist. If there is no oil mist, it indicates that the vacuum pump is in good condition. If there is continuous smoke, it indicates that the vacuum pump is leaking. P. S. The refrigerant meter cannot detect vacuum. Please repeatedly check whether the external interface is tightened.
