Dual Duct Air Terminals may also be suspended with factory-supplied and field-installed hanger brackets and field-
supplied and installed hanger rods. (See figure 3)
Primary air inlet
Dual Duct Terminal Units are not designed nor suitable for outdoor use.
In advance of start-up, verify all electrical connections are tight and the correct voltage is supplied to the Dual Duct
Terminal Unit per the rated voltage listed on the unit label. If factory-supplied controls are present, review all wiring
diagrams to assure a complete working knowledge.
IMPORTANT
If equipped with pneumatic controls, the orientation of the Dual Duct Air Terminal unit is critical. The pneumatic
controls must be mounted right side up. The Dual Duct Terminal must be level within + or – 10 degrees of horizontal,
both parallel to the airflow and at right angle of airflow. The control side of the Dual Duct Terminal is labeled with an
arrow indicating up. Unless otherwise noted, most electric, analog electronic and digital controls are not position
sensitive and may be installed in any orientation.
MINIMUM CLEARANCE FOR ACCESS
Dual Duct Air Terminals require sufficient space to allow servicing of the controls and electric reheat power hookup
(if applicable). Horizontal clearance requirements are dependent upon access panel dimensions which are indicated
on the appropriate submittal. For control panel access, a minimum of 18" is recommended. See the appropriate
submittal for control panel location.
These clearance recommendations are not meant to preclude NEC requirements or local building codes that may
be applicable, which are the responsibility of the installing contractor.
