Aprilaire 600m install, bypass duct question

I was thinking of installing the 600m on the return side and running the bypass duct up to the top of the supply where it goes horizontal ( top of the 3rd pic) since there is not enough room above the AC coils. Or do you think it would be okay to install it on the supply side adjacent to the AC coils (4th pic)?

I figure I would mount it myself, hire someone to plumb in a tee valve instead of using the saddle valve, and then finish the wiring myself.

Opinions? recommendations?

Thanks in advance.

ok so now that its mounted i need help wiring this puppy in. i am hooking it up to a Carrier model# 59sp5a single stage furnace. Is the HUM terminal already 24V? or do I need to use the transformer? what is the other terminal i need to use to complete the circuit to the humidistat and humidifier?

The HUM terminal is a 24 VAC output, energized when the gas valve relay is operating during a call for heat. Connect an accessory 24 VAC humidifier to the --in. male quick--connect HUM terminal and COM--24V screw terminal on the control board thermostat strip.
