- 本产品配用电源必须符合风机铭牌标示的额定参数；电机过载保护装置请用户自行配置。
Power should be conformed with the rated parameter of blowerNameplate; overload protection device of motoris equipped by user.
- 风机使用前要测试绝缘电阻，阻值应大于2兆欧；热态或温度较大时，绝缘电阻应不低于0.5兆欧。
Please test the insulation resistance before application; the value should be over 2MΩ,and it cannot be less than 0.5 MΩwhen thermal state or temperature is higher.
- 风机启动前请检查外观是否完好，连接是否可靠，风轮转动应灵活无阻滞，如发现异常请立即停车检查。
Before operating the blower, please check the blowerwhether the outlook is fine and the connection is reliable or not; wind wheel spinning well without retardance, otherwise, stop operation and exam it immediately.
- 建议每周至少通电运行一个小时，防止电器元件受潮及润滑脂凝固，并清除风机内部积尘，若使用环境温度较低或温度较大时，应适当增加开机次数或通电时间。
User had better operates it not less than an hour per week to avoid components damping and grease lubricant freezing, and it can also clean the inner dust. It should be operated several times if working environment temperature is lower or higher.
