The bottom heating unit just slips out of the cabinet to reveal a solid floor with a cut out in the back panel for the electrical. Took the unit outside and gave it a good bath and let her dry in the sun yesterday afternoon. The odor that was present is no longer there and she is clean and smells good.
Another view of the cabinet with the guts taken out for cleaning.
Back vent taken out and scrubbed and all nice and clean.
Took the electronics compartment apart to see what was in there. The fan compartment is separated from the electronics by a panel and is separated from the heating chamber by a panel. It pulls air from the cabinet and blows across the heating elements in the heating chamber and up the back thru the vent panel. That fan puts out an enormous amount of air. Don't know what CFM it is but that little puppy cranks the air.
There are 2 110 Volt heating element in the heating chamber. The fan blows over the elements and then thru the openings that feed the vent chamber that is part of the back wall. The humidity pan has a heating element but I did not take it apart to see what it was. There is a sensor that will read the humidity and turn that heater on and off. Not sure if this will get hot enough to smoke chips or not. I am still thinking that the AMAZ-N PS will put out enough smoke. Will have to test that when I vent the top.
Cleaned out the electronic cabinet and put it all back together and plugged it into the garage 110 circuit and the GFCI would not hold. Had to run a heavy drop cord inside to get the thing fired up. Within 30 mins she came up to 130 degrees and in 45 mins was running at 160 degrees. I shut it down at 160 as I was satisfied in what I was seeing. With the way the framing is built I can put 1 inch of insulation in it. 2 layers of 1/2 inch Polyisocyanurate insulation will give me about an R 7 value so that will help a bunch to hold the cabinet temp. The Polyisocyanurate insulation is rated for 300 degrees and I don't plan on getting the temp above 250 and will most likely only get it to 170 to 175.
The electronic cabinet has some space between the sides when it is shoved in so I am thinking that I may not have to cut any vent holes to bring outside air in to vent the cabinet. I will only know for sure when I cut a vent hole in the top to see how it is drawing.
I will cut a hole in the face plate and put an outlet in to run the PID and another outlet hole to run the contactor that will turn the heating elements on and off. I am still thinking of converting the elements to 220 volt. I will either install a single circuit non GFCI 110 outlet or a 220 outlet in the garage to run this thing.
Bottom line is that she is clean and she works. Now I have to vent it and find someone that has a brake to bend some metal so I can build the exterior skin and insulate it after I put a vent in.
Back when I make more progress.
