Do you have to worry about the heat melting the DFI backing plate?
Acutally, unless you forgot to turn off loadtester at the end of test, it should start feeling cold at back. With cascade, the backside start getting water drips... You see, the evap should be cooling well enough to cool down entire copper since there is no other way of heat escaping other than through evap (thoeritcally) from load tester with all the insulation. Some resistor load tester people showed with no frost to me looks like just bad contact with no correct load on evap.
And thanks to nature of cartridge heater, variance with temperature and resistance is very minmal which you could run for hours.
Another tip... never let it run unattended. Your unit might not hold load and collapse and temp will just keep going up.
