On first use, open the upper cover of the water tank and inject cold water till the water level reaches the height of the upper water outlet. 2. Link tightly the tube to the sucking tap. Then put through the power and the pump begins to work. 3. If the machine need to work for a long time, the temperature of the tank water will rise effecting the vacuum degree. At this time, connect the drain hose with tap water and drain water from the water outlet. You need to control the amount of the tap water so as to keep the temperature of the constant and the vacuum degree stable.
