Hi! Started some eggs in my incubator today, and just realized the instructions given (and which I followed) are for the circulated air model when I have the thermal air model. The instructions say to fill trough C throughout the incubation and fill both troughs C and T at 2 to 3 days before the hatch. HOWEVER these are the instructions for a circulated air model and my model is a thermal air flow. Elsewhere (briefly, under "Moisture") it says if it is a thermal air flow incubator keep trough T filled at all times. So now I'm confused! Just trough T (or is it trough T and C)? And if it is just trough T do I later fill trough C and T before the hatch? Does anyone know? Why did it come with instructions for the circulated air model (which it is not) and not for the thermal air flow (which it is)?! Was it a mix up at the factory or are they just terrible instructions? Can't find info on the internet. Help!
