1) Either device is full and the display is set to P2 and "waterfull" ... okay. If I now the reservoir empty and back insets properly, so is according to instruction, the device continues (reportedly for about 3 minutes for the compressor protection circuit) in mode P2 with indication "waterfull" remain before it returns to normal operating mode , These 3 minutes can be veeeery long. Once the unit stayed up all night in the P2 ("waterfull") mode.
2) or device is full and the indicator is visible in P2 and "waterfull" ... okay. After emptying of the reservoir, the device will immediately jump back to normal operating mode without 3 minute wait.
It happened this way ... this way ... but unfortunately never as it is in the manual. Strangely, it is all.
Today (08/03/2015) I have emptied against 16:20 clock the container. Now (16:40 clock) is the unit still on P2 ("waterfull") .... 3 minutes are with me but not quite as long :-) So I will have to check a few times today.
A small drawback is of course the power consumption. At 450 watts the unit draws purely 10.8 KW per day .... because one looks forward to the next electricity bill :-)
The noise is more than bearable. The low hum would not even bother me in the apartment. In the workshop which is also matter. There is still a second meter. The displays of both units differ only by max. 3 percentage points of each other.
