The main electrical power supply connection for the Spectrum Blower is made directly
at the junction box underneath the outer weather cover and below the motor. Refer to
the wiring diagrams in
An external disconnect is required and should not be mounted to the Spectrum

Step 1
Access the J-Box by removing the top weather cover (as shown in Figure 4-1) of the
blower base. This weather cover is held in position by machine screws, and once they
have been removed, you will have access to the J-Box of your blower.
Step 2
Run inlet power through the roof within the curb, to the J-box of the Spectrum Blower.
The gap between the end panel and the base allows electrical conduit to run
directly underneath this panel. No special cutouts or modifications are necessary.
Use the strain reliefs provided in the J-box to secure the power wiring.
