What to do if VARON Medical Equipment runs but the flow rate is small?

  Peter BaileyAug 8, 2025
  If your VARON Medical Equipment runs after starting but the flow rate is small, it might be due to a low flow rate setting. Try turning up the level of the flow rate. Alternatively, the tube might be twisted or blocked; in this case, straighten the tube. If the connecting tube inside the machine is disconnected or broken, disconnect the power supply and have it repaired by professional maintenance personnel.

What to do if VARON Medical Equipment indicator light is normal but the machine fails to work properly?

  Allison JacobsAug 17, 2025
  If the indicator light on your VARON Medical Equipment is normal but the machine isn't working properly (making abnormal sounds), there are a few potential causes. It could be a compressor failure or that the connecting tube inside the machine is disconnected or broken; in either case, disconnect the power supply and have it repaired by professional maintenance personnel. Alternatively, the ambient temperature may be too high, activating the self-protection program of the oil-free compressor. This is normal, and the machine will restart automatically when the temperature lowers.
