balancing system
The HRV must be balanced
properly in order to operate at
maximum performance.
Greentek TM products are equiped with
balancing damper to help eliminate the
risks.
figure 8.5 Static model with motorized
dampers (Model SHM)
Mount the damper motor by aligning the pin on the damper motor to the hole on the unit’s top plate
and the align the damper motor coupling with the damper shaft. (figure 8.2)
Align the damper in the fully closed position. (figure 8.3) Using a 1/8” Allen key tool inserted in the
locking screw, rotate the coupling slightly clockwise just enough to exert a slight torque on the damper
mechanism and tighten the lock screw. (figure 8.4)
Dampers should now be in the fully closed position with no power. Identify desired wiring diagram
shown at page 14 of this guide. Activating the damper motor should open flaps to 90°. If the damper
flap do not open fully, coupling might need to be readjusted to allow for more or less spring tension
when fully closed.
