3.0 exterior & remote exterior pre-installation
FOR EXTERIOR AND REMOTE EXTERIOR INSTALLATIONS ONLY
For exterior and remote exterior installations, you must follow the instructions below before beginning installation.
For inline installations, see "remote inline pre-installation" section.
1. Insert the blower housing assembly into the exterior housing assembly. Ensure correct orientation (Fig. 1).
note:
We recommend installing the inline cover assembly and decorative cover last, after all electrical wiring is
complete. See "electrical information" section for installation instructions.
2. Secure the blower housing assembly to the exterior housing assembly using 4 screws (supplied) (Fig. 2).
3. Install the air damper assembly onto the collar and secure using self-drilling screws (supplied) (Fig. 3). Rotate
so that the damper closes shut when the blower is not running.
note:
The air damper assembly must be closed when the blower is not running for the system to function correctly.
