Black Max Hints
- The unit does not validate proper operation, best to add an inline hygrometer as described in section Engine_Dehydration#Accessories. The hygrometer should show 10% or less humidity during operation.
- The Peltier element may become weak which leads to improper dehydration (e.g. going down to only 30%). To validate proper cooling, open the device (caution: 120V inside, also on the PCB) and measure the voltage of the temperature sensor between the black (BL) and white (WH) wires

The voltage must be lower than 0.6 volts in the cooling cycle. If above 0.6V, please contact customer support.
