Connection to VORT HA: if the Neti appliance is equipped
with an HA unit, the heat recovery unit must be connected to
this unit by way of the brown/blue/black three core cable
coming from the unit, as in fig.15. In this case, accordingly, the
display will no longer be connected to the heat recovery unit
but to the brown/blue/black three core cable on the VORT HA,
as indicated in the VORT HA manual.
