Amber Light from overdriven air separator stays on or won’t go off

If the warn­ing light is stay­ing on when you use your air sep­a­ra­tor, your air sep­a­ra­tor ‘flow knob’ set­ting is prob­a­bly over adjust­ed. It only takes about 10 sec­onds to fix this one, but it can take 20 – 30 min­utes of addi­tion­al time run­ning the air sep­a­ra­tor for the dys­func­tion­al light and/or alarm to reset.


  • Amber Oxy­gen sen­sor light won’t go off

To Trou­bleshoot:

  • Dial Flow meter back so ball is rest­ing at 9 1/2, just under the ‘10’ (Or 4 1/2 if a 5L
  • Let unit run for 30 addi­tion­al min­utes to give unit time to reset

This video demo shows the ball float­ing at the prop­er lev­el, 10 LPM. The ball drops when I pinch the line to block flow. The ball returns to the 10 LPM lev­el when flow resumes.

Please also check the fol­low­ing oth­er poten­tial issues that could cause the warn­ing light to go on:

  • Air Sep­a­ra­tor should be plugged into ded­i­cat­ed cir­cuit that is sep­a­rate from oth­er major appli­ances (refrig­er­a­tor, AC, etc)
  • Air Sep­a­ra­tor should NOT be con­nect­ed to out­let using pow­er strip,surge pro­tec­tor or an exten­sion cord
  • All hoses from Air Sep­a­ra­tor to Reser­voir need to be free from ‘kinks’ or bends so that air may flow freely
  • Air Sep­a­ra­tor should have a min­i­mum space around the perime­ter so oper­a­tion and air intake will not be imped­ed
  • Air Sep­a­ra­tor should be used in a clean envi­ron­ment with even tem­per­a­tures

*Please note* If you live at a high­er alti­tude and have a refur­bished air sep­a­ra­tor, there is a chance that your air sep­a­ra­tor may be hav­ing issues per­form­ing opti­mal­ly at a high­er alti­tude. If this is the case, you may con­tact us to inquire about ser­vice options.
