The Air Still Pro has safety shut down features built into it.
For example, if there was a blockage in the column that prevented vapour from passing up through it or the boiler shut off due to a malfunction or a dry boil, the Air Still Pro head unit detects this and activates a warning mode.
The head unit and boiler will be powered off and a buzzer will sound 5 loud beeps. The LED Mode Selector Button will continually flash red. This same warning pattern will also occur if there is a problem with the temperature probe at the top of the column. This warning mode applies to both Reflux mode and Pot Still mode.
The unit and boiler may also shut off in Reflux Mode if the column temperature deviates too far from the running average temperature, over a period of time. For example, this may occur if there was surge boiling going on inside the boiler and column due to the lack of Distilling Conditioner (or Anti-foaming agent) and Ceramic Boil Enhancers in the boiler. This may cause temperature fluctuations (spikes and drops) and the unit will enter into an early cool down phase. During this phase, the boiler will power off (the red light on the boiler will turn off) and the LED Mode Selector button will flash Green for 10 minuets and then turn off. Your run has ended prematurely.
What do I do if my unit enters warning mode?
If your unit has made 5 loud beep sounds and the LED Mode Selector Button is flashing red -
- Turn the unit off at the mains power outlet wall switch for 30 seconds and turn it back on.
- Press the LED Mode Selector Button to enter standby mode (the LED Mode Selector Button will glow white).
- Press it again to enter Reflux Mode.
If the unit immediately enters into the Warning Mode again, there is a problem with the temperature probe. Turn the unit off at the mains power outlet wall switch and contact contact customer support.
If the unit enters into normal operation when attempting to enter Reflux Mode, turn the unit off again and contact customer support.
