Considerations before installing the heating
The first the heating power cable.
The first thing is to cut the original cable, they are generally identified because they are the 2 cables (red and black) but fat, and they usually have rings at the ends, at the height of the white connector (the black depending on the model) some are left 3 fingers and cuts. to replace it with a 6mm one to the battery, except if the battery is right next to it, 0.5/1m maximum. NEVER CONNECT IT TO A LIGHTER SOCKET.
doing this, we will get it when we have low battery, voltage drop (at startup) does not affect and can start normally. You might think it's too fat, I'm not telling you no, but if you want to make sure it starts well, do it, If you put a thinner one and it doesn't start, you know why..
Update 14/12/2023
After detecting some units (VERY FEW) the fat connector of the control unit fails, It is detected because there is still a drop in voltage with respect to the battery, or the connector gets hot, so the solution would be to cut the power cable just before the connector, and put a strip on it, or something more curious like a XT60 as can be seen in the image, and it would be completely resolved.
The second heating mounting position
The position in which we mount the heating, and the area where it is mounted are very important and its location must be studied very well before drilling anything.. If mounted outside, It must be ensured that the heater is mounted in an area protected from splashes and water ingress..
When the assembly is inside the passenger compartment, it is very important to ensure that the combustion air inlet pipe, exhaust gas outlet pipe and fuel pipe are perfectly sealed through the support gasket. Or if it is not possible with the undulations of the ground, Assemble the plate supplied with the heater and seal its perimeter to prevent smoke leaks inside..
He silicone seal whether black, rojo, orange etc., located at the bottom of the heater not on the outside of the vehicle on the underside, It always has to be flat where we mount it, so that there is not smoke leaks inside the vehicle.
In the image we can see the recommended positions for the correct operation of the heating, in addition to the normal mounting on a flat surface.
To do this, the wood/plastic floor will almost certainly have to be trimmed., You will have to leave enough space so that the casing does not touch anything, otherwise when turning it on, the fan will rub against the casing.
If you turn the heater 90º, you must make sure that the diesel inlet must ALWAYS be at the top as in the image above., otherwise it won't work well, it smelled like diesel, diesel will drip.. etc..
Los 2 gas tubes, They should ALWAYS go outside, never take out just one, There is a risk of malfunctions and smoke entering the vehicle interior.. And if it is rotated 90º the diesel tube should be at the top as in the image.
Third the air to be heated
The air intended for heating may be fresh air or recirculated air and must come from a clean area., that cannot be contaminated by exhaust gases emitted by the heating itself, vehicle engine or for example a heater or generator.
Room air inlet and outlet
The cold air inlet and hot air outlet tubes NO They can have a very pronounced curve, and less than 10 centimeters of heating, otherwise, you can meet him error code E-05.
Quinto The gas outlet
The exhaust always has to fall towards the ground, without having “stomach” as straight as possible, and if you make a sharp curve, try not to do it right at the heating outlet, or you will have carbon problems. Also must be in direction opposite to the direction of travel, both the exhaust and the combustion air inlet.
The two gas tubes, those at the bottom of the heating, They must ALWAYS go outside for safety and proper functioning., In case of not doing so, if for some reason the power is disconnected or fails, smoke would enter the interior.
Sixth Fuel pump position.
It is discussed and recommended in all diesel heating manuals., it has to have a tilt or it won't work properly, that's false, I have tried it myself in all possible positions without any problem..
Putting it like this is so that the air that the tube may have, go up and out by the heating itself, but due to assembly issues that is almost never fulfilled.
Diesel pump with built-in filter
About him diesel filter, they ride BEFORE of the pump, They are usually quite bad, over time they tend to cause problems, from king, air enters.. and cause the heating not to turn on. The best solution is remove filter, (In my case I have not assembled any, at my own risk) or you can set one up 22ml pump with integrated filter.
Not all manufacturers send the same diesel tube, some like him “soft” of pvc, They are quite delicate, they fold, They do not resist heat well, cause bubbles, etc.. If it arrived with the tube that you can see above (It is green and transparent.) I recommend that you throw it away and buy it. reinforced diesel pipe, It is not expensive and can avoid problems or It is other type of tube.
Seventh Where to get the diesel intake from?
Have 2 options, with a T or through a espadin. The best is undoubtedly the sprat, does not interfere with the vehicle's fuel system. But to simplify assembly, many users prefer to mount the T, personally, to do so, I would ONLY put it in the diesel fuel delivery pipe., before the vehicle filter and mounting a non-return.
In some vehicles it can be mounted on the return, because the tube reaches to the middle or bottom of the fuel tank, when that is not so, the heating may or may not work, or stop at any time, giving the error code 8 o 10.
I will soon leave a list of vehicles, with the data of the members of the Facebook group where they have indicated the model to me, year and if they have mounted T or sprat.
Eighth Heating settings
Just because it's the last thing, it's not the least important., quite the opposite. After trying many types of configurations I have managed to find the “ideal configuration” for this type of heating. Depending on the model and type of pump, it will be one configuration or another, you can see them by clicking HERE.
We currently call it “altitude sickness setting” can lead to confusion due to the name, but that configuration should be on EVERYONE of not doing it over time, black smoke started coming out, heat less, hard to start, and it will stop working, and it will be because it will be filled internally with carbon, and you will have to disassemble it to clean it.
