I got an undercounter fridge from craigslist, an STC from ebay, and a 4 inch junction box from Home-Deposit-Your-Paycheck. The operation instructions packaged with the controller were impossible to understand, the wiring diagram was skimpy.
A quick search of HBT turned up both wiring and operating steps. No sweat. I extended the fridge 2.5 inches with wood and it fits a 7 gallon bucket.
BTW. for people looking for an enclosure, either of these work for a controller and duplex outlet:
- 4 inch blue PVC junction box intended for conduit. Use a metallic cable clamp and drill a small hole for the sensor wire.
- Duplex PVC junction box with a 5/8 inch extension. The extension might need a little trimming to easily fit the controller. The heavy-duty duplex PVC box does not fit.
- Definitely use 14 gauge stranded wire, not solid wire, for connections. Much easier to stuff into the box.
