i would add colour and softener (if applicable) first, turn on the pot and the stirring system, when you think its ready hit it with an IR Thermometer and check the temp, if its there i would add salt slowly, then flake and scent. let it run a few min and check the temp again. once its where you want it start pouring, the first little bit would be a wad of salt in the nozzle, so i would crack the valve with a cup under it, once clear i would start filling molds. every time you stop to demold you will have to clear the valve as the salt will settle in there.
always check the temp with an IR Thermometer, the temp controls arent the greatest for accuracy. i tried to pour sticks around 330 checked with the thermometer.
