Thank my DH for this one folks! By request, here are your instructions with diagram:
48 Qt Cooler / Fridge-a-bator
1. The cooler is a standard 48 qt plastic insulated cooler. The Fridge is a small, college dorm size refrigerator , out of which I removed the compressor and electronic switches.
2. I then cut a viewing window in both and covered with 2 layers of plexiglass with an air space between sealed with silicone. The Fridge has an inner plastic panel that has to be removed. I replaced it with metal flashing. I covered the window on the Fridge with wood trim.
3. The inner workings of both are the same. The Fridge had to be placed on its side because of extreme temp readings while it was standing up. My boxes contain
A: 12vdc fan from a computer ,
B: 9-12vdc small power supply to drive the fan,
C: Wafer thermostat ,
D: Ceramic bulb socket w/ 60 watt bulb,
E: Nightlight.
Wiring is as follows.
1. One leg of the 115vac (from the house power) is connected to one side of the wafer thermostat, 9-12vdc power supply, and finally the nightlight.
2. The other leg of the 115vac is connected to the other side of the 9-12vac power supply, nightlight, and the ceramic bulb socket.
3. The remaining leg of the ceramic bulb socket is connected to the unused wire on the wafer thermostat.
4. Connect 9-12vdc to 12vcd fan. From power supply.
****NOTE: With a lightbulb as the heat source, we always put a deflector made from aluminum flashing in front of it to keep eggs in that area from cooking from concentrated heat. The bulb is a 60 watt bulb in both hatchers
