1.1. During the hoisting and transportation of the equipment, ensure that no one is standing under the equipment.
1.2. The equipment must be installed on a stable foundation. The depth of the foundation can be determined by the user according to the local geological conditions. If the equipment is placed upstairs, before installing the equipment, please confirm whether the floor can bear the weight of the equipment when it is fully filled with feed water or beer liquid. If it cannot bear the weight, place it in a different place or take strengthening measures.
1.3. The equipment layout should be reasonably arranged in accordance with the process requirements, with ease of operation as the main standard.
1.4. During the installation of the equipment, any component should be installed under power-off conditions, and warning signs can be hung if necessary. It is not allowed to start commissioning and commissioning before determining whether there are personnel or potential safety hazards within the dangerous range of the equipment. During commissioning, the pump valve should be opened by jog to avoid damage to the machine.
1.5. The main power supply of this equipment adopts 380V, 50Hz power supply, please check the local power supply. The wires and cables used in the equipment installation must use the standard cables specified by our company, and the wiring must be connected in strict accordance with the wiring diagram.
1.6. The power distribution control equipment should be placed near the operating location, where it can be quickly stopped in the event of a failure. As long as the device is connected to the power source, even if the device is turned off, the power is not actually turned off. If you do not plan to use the machine for a period of time, please cut off the power of the device from the main power supply.
1.7. During the use of this equipment, some components will generate a high temperature of about 100°C, which may cause burns.
1.8. A large amount of steam will be generated during the beer production process. The indoor production equipment must have a good exhaust device to prevent a large amount of steam from condensing, which greatly increases the indoor air humidity, corrodes indoor objects, and even affects pumps, electromagnetic valves, and control equipment. And other power facilities cause harm and bring serious safety hazards.
1.9. The washing liquid used for cleaning and disinfection is a highly corrosive liquid. The operator must wear protective gloves and a face mask during operation. If the liquid accidentally splashes on the body, it should be cleaned with plenty of water immediately and consult a doctor for diagnosis.
1.10. When the crusher is running, don't put your hands in the hopper to prevent the machine from being crushed.
