1、安装地点需通风良好，发电机端应有足够的进风口，柴油机端应有良好的出风口。出风口面积应大于水箱面积1.5倍以上。
1. The installation site shall be well ventilated. There shall be sufficient air inlet at the generator end and good air outlet at the diesel engine end. The area of air outlet shall be more than 1.5 times that of water tank.
2、安装地的周围应保持清洁，避免在附近放置能产生酸性、碱性等腐蚀性气体和蒸汽的物品。有条件的应配置灭火装置。
2. The surrounding of the installation site should be kept clean and avoid placing articles that can produce corrosive gases and vapors such as acid and alkali nearby. Fire extinguishing devices shall be equipped if conditions permit.
3、在室内使用，必须将排烟管道通导室外，管径必须≥消音器的出烟管直径，所接之管路的弯头不宜超过3个，以保证排烟畅通，并应将管子向下倾斜5-10度，避免雨水注入；若排气管时垂直向上安装的，则必须加装防雨罩。
3. For indoor use, the smoke exhaust pipe must be led to the outside, the pipe diameter must be ≥ the diameter of the smoke outlet pipe of the muffler, and the elbow of the connected pipe should not exceed 3 to ensure smooth smoke exhaust, and the pipe should be tilted down 5-10 degrees to avoid rainwater injection; If the exhaust pipe is installed vertically upwards, a rain cover must be installed.

4、基础采用混凝土时，在安装时须用水平尺测其水平度，使机组固定于水平的基础上。机组与基础之间应有专用防震垫或用底脚螺栓。
4. When the foundation is made of concrete, its levelness must be measured with a level bar during installation to fix the unit on a horizontal foundation. There shall be special shockproof pads or foundation bolts between the unit and the foundation.
5、机组外壳必须有可靠的保护接地，对需要有中性点直接接地的发电机，则必须由专业人员进行中性接地，并配置防雷装置，严禁利用市电的接地装置进行中性点直接接地。
5. The unit shell must have reliable protective grounding. For generators that require direct grounding of the neutral point, the neutral grounding must be carried out by professional personnel and equipped with lightning protection devices. It is strictly prohibited to use the grounding device of mains power for direct grounding of the neutral point.
6、发电机与市电的双向开关必须分开。
6. The two-way switch between the generator and the mains must be separated.
机组本身各种材料会与机油、冷却水、柴油、空气等发生复杂的化学、物理变化，可能导致机组出现如下故障。
Various materials of the unit will have complex chemical and physical changes with engine oil, cooling water, diesel oil, air, etc., which may cause the following faults of the unit.
1、水进入柴油机，由于空气中水气在温度的变化发生冷凝现象，结成水珠挂附在油箱内壁，流入柴油，致使柴油含水量超标，这样的柴油进入发动机高压油泵，会锈蚀精密耦合件柱塞，严重的会损坏机组，定期维护即有效可避免。
1. When water enters the diesel engine, due to the condensation of water vapor in the air due to the change of temperature, it forms a water droplet hanging on the inner wall of the oil tank and flows into the diesel oil, which causes the water content of the diesel oil to exceed the standard. Such diesel oil entering the engine high-pressure oil pump will rust the precise coupling plunger, and seriously damage the unit, which can be effectively avoided by regular maintenance.
2、机油变质，机油的保持期（二年）发动机的机油是机械润滑作用，而机油也有一定的保持期，长时间存放，机油的物理化学性能会发生变化，造成机组工作时润滑状况恶化，容易引发机组零件损坏，所以润滑油要定期更换。
2. The engine oil deteriorates, and its retention period (two years). The engine oil is used for mechanical lubrication, and the engine oil also has a certain retention period. The physical and chemical properties of the engine oil will change when stored for a long time, resulting in the deterioration of the lubricating condition of the unit during operation, which is easy to cause the damage of the unit parts, so the lubricating oil should be replaced regularly.
