Converting to 240 (shared neutral)

The instructions show a jumper located on 4 and 5 of "TB-1". I understand it shows a sub panel. Im disregarding that part. HOWEVER, these instructions seems to show the 30amp circuit NOT including a neutral. It appears that the jumper on the panel will be serving to SHARE the neutral from the 120v circuit that also enters the tub.
Can I remove this jumper, and then wire each circuit with its own neutral? Or should I leave the jumper and only run a 10-2 for the 30 amp circuit and allow the neutral to share(completely assuming that is what the jumper is doing)?

So, your not going to follow the directions, nor are you going to do a legal installation, up to code, and you'd like some help with this?

If you can't sell it on eBay, it may not even qualify as landfill.

There are times we can give points for creativity. While sitting in a big bucket of water connected to 50amps of AC power isn't one of them. Also, your drawing lacks detail, depth and the composition is pretty terrible too. So no creativity points there either. Sorry...

When you were young and a fuse blew in the house was it your job to go look for a penny to replace it?
Mis-wiring the neutral is a common issue we've seen discussed here with Hot Spring spas. Why not just do it the proper way, you've only got to do this once and the extra cost spread out over the multiple years you'll enjoy the spa makes it a no-brainer to me to just get the subpanel and wire it per the schematic.
