Fuel Pumping Mode

After installation of the heater for the first time, the fuel pipe needs to be filled up with

diesel. Only when the diesel entering the heater from the fuel tank, the heater could be

operated successfully.

Operation method: In the shutdown state, press and simultaneously. When the

screen lights up showing “Polr”,release the button. The buzzer sounds once (release the

button) to enter the Fuel Pumping Mode. 80 seconds later, the fuel pump will enter the

state of rapid pumping (500 times of pumping diesel ). When the fuel pumping is

completed and the diesel enters the heater, it will ignite and run automatically. If the

diesel doesn’t enter the heater, the screen will display P—1 (Figure 3). Press the key at

this time, and the system will start the fuel pumping procedure again.

The start times of the fuel pumping mode depends mainly on the length of the oil

circuit. When pumping diesel, you can observe the progress of the fuel filling in the fuel

pipe to judge whether it is normal.

NOTE: This chambre5is only for initial installation and when there is no diesel in the oil

circuit. Do not use it at ordinary times to avoid flooding the combustion chambre.
