Heater Check after Repair.
7.1 After repair, the heater should be tested for efficiency on the DV1105.000 stand, and
after that it can be installed on the vehicle. (The heater can also be tested on the vehicle on
which it will be used).
7.2 Connect the heater to a 12 or 24 V power supply (depending on the heater) and to
the fuel tank. Then fill the fuel line to the heater by means of a fuel priming device. Start the
heater. The heater should start at the minimum power mode which is set by the
controller. The heater should operate at the minimum power mode for at least 10 minutes.
While changing the power mode of the heater by means of the controller from the
minimum to the maximum value, make sure that the intensity of heating increases.
7.3 At maximum power mode, measure the temperature difference between the inlet
and the outlet of the heater, the exhaust gas temperature, and carbon monoxide (CO)
content. Temperature difference between inlet and outlet should be at least 70
90
С.
Exhaust gas temperature should be not more than 500
С. The carbon monoxide (CO)
content should be not more than 0.1%.After conducting the measurements, switch off the
heater. The LED on the controller will blink frequently, which means that the purging
process is underway in the combustion chamber. After purging is finished, the LED will
blink infrequently, which means that the heater is not working. When the work is
completed, turn off the power and dismount the heater from the test stand.
If in the process of starting or running the heater, there was a crash, for whatever
reason, and the heater was turned off, the display panel of the controller will show a fault
code. Once the cause of the failure is corrected, the test should be repeated.
When the heater is mounted on the vehicle after the repair, it should be checked for
proper operation both with engine off and on.
Attention! The cabin sensor, if installed, should be disabled, if you have to run
the heater when the air temperature is more than 30
С.
