20 14 Where and how does the Ou Man rear eight-wheel preheater operate?

Next to the preheating magneto under the engine cover, start to determine that the fixed position of the preheater is at least 20-40 cm lower than the water tank cover.

1. Start to determine that the fixed position of the preheater is at least 20-40cm lower than the water tank cover.

2. Determine the positions of the ventilation holes, warm air pipes and small circulation pipes of the series engines.

3. Choose the installation method and cut off the warm air pipe.

4. Connect and lock the water inlet of the preheater with a low-cut hose.

5. Add the coolant slowly until the coolant flows out of the preheater outlet.

6. Connect the outlet of the preheater with the cut hose and lock the hose.

7. Fill the coolant to the specified amount and check whether there is any leakage.

8. Start the automobile engine, completely exhaust the gas in the pipeline, and replenish the coolant to the standard amount.

9. Connect the 220v power supply and do a good job of testing. The power indicator is red and the work light is green. After turning on the power supply, the two lights are on at the same time, and the preheater vibrates slightly. At the same time, the shell of the preheating chamber will be slightly heated. When the engine reaches the starting temperature of 40-50 degrees, the green light goes out and the preheating is completed.
