How to Install the CoolBot in your Walk-In Cooler
Installation Instructions
Anyone can install a CoolBot. Here's the basic installation instructions (detailed instructions with pictures as well as a toll-free support number come with your order).
- Install any brand of window A/C unit which you've purchased separately. (See the table below for sizing.) We just cut a sloppy hole in the wall of our home-built walk-in cooler with a chain saw, stuffed the A/C unit into the hole, and then used “Great Stuff” foam sealant to seal up the gaps.
-
Plug the CoolBot into a standard A/C outlet - it uses no more electricity to run than a cell-phone charger, so no special electrical connections are needed.
-
There are three labeled wires coming out of CoolBot: one measures the temperature of the room, just let it hang free.
-
The second wire (labeled frost sensor) you stick into the cooling vent fins of the A/C unit. It holds there on its own, you don't need tape or screws or anything.
-
Attach the third wire to the temperature sensor you see sticking out of the front of your A/C unit. (It's the only thing you'll see attached to the front fins of your A/C unit. Sometimes it's black with a little bulbous end... sometimes white with a little bulbous end... Just wrap the CoolBot wire and the end of that temperature sensor together using a small 1/2 inch by 1 inch piece of aluminum foil to ensure a good thermal connection.
NO PERMANENT MODIFICATIONS ARE MADE TO YOUR A/C UNIT!
