The ARP website has a ton of good information about absorption refrigerators and about their product. The concept of their product is very sound and the execution is brilliant. But the web site is poorly organized and it takes a bit of effort to get the maximum benefit. I installed the defender with two inside fans and one outside and it was an interesting DIY project. I didn’t want to mount the outside fan on the removable vent cover so I made a simple bracket so I could secure it Inside the opening. I’m a big fan of these fridges due to their simplicity and low power needs and this modification seemed pretty worthwhile to me.
