Check pump configuration!
It is strongly recommended to check that the pump is set to 22ml, There have been cases where it has come in at around 16ml which causes smoke/charcoal..

Operating modes

Power mode: Has 10 functioning levels, of the 1 al 10, Once adjusted, it will remain that way until you modify it or turn off the heating..

Thermostat mode: In this mode you can choose between 8º and 36º, depending on the temperature you choose, The heating will automatically adjust the power necessary to reach it.. In this mode you can choose 2 variants:

  • normal mode: In normal mode when it reaches the temperature, It will remain running at minimum until it is necessary to increase the power to maintain it..

purged mode

  1. You have to disconnect the screen or remove the heating fuse
  2. We press the icon of the “gas station” at the same time we connect the screen or replace the fuse (WITHOUT LETTING IT GO)
  3. Hara a self-diagnosis, once finished, We continue holding down the gas station icon until a message appears. 300 on the screen and it will start purging, showing a countdown on the screen.
  4. When you press the off button, will stop.

CAREFUL!! If it is the portable version, it is NOT necessary to purge, on first boot, or it fails, In the second it will start on its own without the need to purge it.. If it is a model “normal” not portable, yes it is done until the diesel reaches the heating.

Purging excessively will cause a large amount of smoke to come out at start-up., and it would have to be left still until the smoke disappears, if we stop it, On the next boot it will happen again.

Height mode

This model can function correctly up to +o- 2200m in a timely manner can overcome them without problem, but it is advisable once you are below that height to turn it to the maximum and give it a go. 10-20 minutes at least to burn any possible trace of carbon that may be in the combustion chamber.

For long periods above 2200m it is advisable to upgrade to the screen ch22.
