I personally don't have a absorbsion fridge but if I did, I would seriously consider adding the ARP..
But you are a brave soul posting anything on this forum that isn't within the normally accepted items.. I got blasted for attempting to let folks here know that the ARP possibly provide a longer life for their fridge since the device has a better way to control the boiler temps...
To me, the small price for the device is much cheaper than replacing cooling units and or the fridge.
But what I got out of my post is most folks here do not feel that out of level operation of any sorts will cause any harm since the manufacturer says it is OK to do so... I disagree with that thought.
Go figure, the manufacturer makes a lot of money from selling repair parts and or an new fridge...
