Actuator Mounting; Field Coating Touch-Up - Greenheck Vektor-MH Installation, Operation And Maintenance Manual

Bypass Air Plenum (BAP) and
Isolation Damper Access and

Actuator Mounting

Depending on the configuration and intended operation
of the system supplied, every Vektor plenum section
may not have a weatherhood and bypass air damper.
Typically systems that include a fan which is on standby
will have one less weatherhood and BAP damper
assembly than plenum sections. Refer to submittal
drawings for additional information. The appropriate
guard / cover needs to be removed for installation,
inspection and maintenance.
For Vektor fans with weatherhood - Access to the BAP
damper and the isolation damper, actuator(s) (optional
from factory) and voltage transformer (optional from
factory) mounting location, is gained through the
removal of the weatherhood guard / cover. The isolation
damper assembly can be removed from its location by
sliding it through the opening.
For Vektor fans without a weatherhood - A guard / cover
is located on the side of the plenum section. Removal of
the guard / cover gains access to the damper linkages,
actuator (optional from factory) and transformer
(optional from factory). The entire isolation damper
assembly can be removed through this opening.
If the Vektor units were not supplied with optional
actuators, the dampers have an extended jackshaft for
field mounting a customer supplied actuator.
