1.The installation site should be well ventilated, the alternator end should have enough air inlets, and the diesel engine end should have good air outlets. The area of the air outlet should be more than 1.5 times larger than the area of the water tank. 
  
2.The area around the installation site should be kept clean and avoid placing objects that can produce acidic, alkaline, and other corrosive gases and steam nearby. If conditions permit, fire extinguishing devices should be equipped.
  
3.If it is used indoors, the smoke exhaust pipe must be connected to the outdoors. The pipe diameter must be greater than or equal to the diameter of the exhaust pipe of the muffler. The pipe elbow should not exceed 3 pieces to ensure smooth exhaust. Tilt the pipe downward by 5–10 degrees to avoid rainwater injection; if the exhaust pipe is installed vertically upward, a rain cover must be installed.
  
4.When the foundation is made of concrete, use a level ruler to measure its level degree during installation so that the unit is fixed on a level foundation. There should be special anti-vibration pads or foot bolts between the unit and the foundation.
  
5.The casing of the unit must have a reliable protective grounding. Generators that need to have a neutral point directly grounded, must be grounded by professionals and equipped with lightning protection devices. It is strictly forbidden to use the grounding device of the city power to directly ground the neutral point.
  
6.The two-way switch between the diesel generator and the mains must be very reliable to prevent reverse power transmission. The wiring reliability of the two-way switch needs to be inspected and approved by the local power supply department.
  
7.The wiring of the starting battery must be firm.
