TREATED AIR VENTILATION

ADJUSTEMENT OF AIR FLOW

The appliance is equipped with a dual speed fan motor (factory set on High speed – Curve A) providing for operation
on high pressure drop duct systems. Air flow and pressure drop adjustment, within the tolerance limits (Refer to
curves) must be carried out in the duct network by fitting diaphragms.
When operating with a plenum or a short duct system (Curve B), it is possible to reduce the ventilation speed. To
do this, disconnect shunt B from terminal 12 and connect it to terminal 13.
