Keep in mind: to maximize the air
flow for each damper, the best way
to disable dampers is to start
disabling from the ends to the
center, due to the position of the
DZK related to the air handler.
Keep in mind: when one or more
dampers are disabled, it is
recommended to adjust the
Airflow control parameter to avoid
overpressure on the active
dampers and ductwork
Attach each zone’s duct with its assigned damper. Follow
the local recommendations to insulate and seal the
ductwork with the damper. Make a cutout along the duct
to keep the motor outside of the insulation.
Use of the insulated stopper. If a damper is not used in the
installation, proceed as follows:
• Make sure the damper is closed before installing the
insulated stopper. (The damper will close as soon as the first
zone is assigned.)
• Check that the power cable is disconnected for the damper
motor that will not be used.
• Check that the damper remains airtight with the power ON
and the fan running.
