If you can't keep the AquaHot running then you will need to fill the hot water coils inside the AquaHot with RV antifreeze. The easiest way is to pull antifreeze through the water pump while the water taps inside are turned to full hot until anti freeze comes out the taps. Will of course need to do this on the cold side also.
If the fresh water coils inside the AquaHot freeze and develop a leak, it's a fatal problem
