Restrictors for adjusting the air flow rate
Calculate the flow rate and pressure drop with the aid
of the calculation program (download from
www.viessmann.de)
prior
to installation.
Individual rings are knocked out of the restrictors to
adjust the flow rate. How many rings need to be
knocked out depends on the pressure drop calculation.
