Install the manometer on pressure pipe P1
and P2 and measure the supply air pres-
sure loss through the heat exchanger.
Adjust the main air flow on the supply air
side by adjusting the potentiometer for
the supply air fan until the required pres-
sure difference has been achieved. The
potentiometer can be found on the con-
trol panel.
After adjusting the potentiometers, wait
approx. 2 minutes until the unit is stable
again.
Strong wind against the building may
affect the adjustment of the unit.
