Precautions for air heater use

1.Working voltage: 

For 12v heater, it should be 12v ±2v

For 24v heater, it should be 24v ±2v

2.Use different diesel labels at different ambient temperatures

Suitable for use in areas with a minimum temperature of -14℃
   -35Suitable for use in areas with a minimum temperature of -29℃
   -50Suitable for use in areas with a minimum temperature of -44℃

3.Glow plug:

When you turn on the heater, glow plug will begin to work. Its working time is 260 seconds. Fuel pump will begin to work after glow plug working 90 seconds.

4.Oil pipe:

The length of fuel pipe is different according to the customer's requirements. The normal working time of fuel pump is 140 seconds, but the time will change according to the change of heater environment. If the heater fails to reach 60 degrees, the sensor will send a signal to turn on heater again.

For example, if you use 3.5-meter oil pipe, when you use the heater in the first time, you need turn on heater 2-3 times for the diesel to enter the heater. If the heater is not ignited for the third time, diesel and smoke will flow out of the body. In this time, you should turn on the heater again. After two minutes of burning, the smoke and oil leakage will be eliminated.

5.Test bench: 

If you use the test bench to test the heater, you must use our original harness. And the positive and negative poles must be fixed, otherwise the virtual current of the wire is not enough, and the ignition plug temperature is not enough to ignite.
