● Before installation, use, maintenance and inspection, be sure to read all the contents of this manual thoroughly and use it correctly.
● The power supply voltage must be consistent with that specified by this instrument.
● It is not suitable to run at high speed without load.
● The life of the electrical box is greatly affected by the surrounding temperature and humidity. Please keep the speed control and the motor dry.
● Install the machine first, and then have a professional electrician wire and power on. The ground terminal must be grounded. The high-temperature bath must be connected to the air switch.
● Within 5 minutes of cutting off the power supply, there may still be an electric shock due to the discharge of the inverter or capacitor.
● Pay attention to the damage caused by the hard objects on the body (watches, rings, belt buckles, etc.) on the glass during operation.
● Be careful when connecting the vacuum tube to prevent the human body from breaking the glass with excessive force.
● When you need to use a high-temperature circulating oil bath, pay attention to the damage of high temperature to the human body. Our company recommends using heat-conducting oil (dimethicone, with a kinematic viscosity of 100) that is less harmful to the human body as the solvent. Pay special attention to the high temperature cycle, you should turn on the circulation pump first, let the heat transfer solvent circulate, slowly heat up.
