- this is funny.
I use to do home inspections and one wire in the wrong place can void your insurance coverage along with other common things we d.i.y. people may do or not do.
And even if it is safe and functional, say there is the option of 2 grounds to use instead of one and local code calls for the green terminal instead of the black. If the place gets destroyed for any reason and you did the job without a permit and approved county guy inspecting and documenting everything it's a huge loss. It's not worth being cheap or poor over. i'd hire it out. Not judging you buy the way.

The schematic shows the alternate wiring of K1 for single phase, but that may be for use in manufacturing a different model that ships from the factory that way. The wires from the relay to the heater elements may be soldered or crimped in a way that makes them hard to change in the field. Also, the relay may be hard to access. You might want to check these before installing a circuit. In fact, if it was me I would want to have the conversion made and then test it on a temporary circuit before investing in a permanent circuit.
Although the schematic shows the heater elements wired back to K5, your electrician might decide that an easier field modification is to leave K5 alone and just move the wires at the terminal block. He or she may decide that all they need to do is take the 3 wires running from the terminal block to K5 and put all 3 in lug 1. Then take the 3 wires returning from the heater elements and put all 3 in lug 3. This would be especially easy if the terminal block has screw fasteners.
This is definitely field swappable. The connections on K5 are all ring terminals and TR1 is a spade terminal. I can do the swap in a little over one minute. I will take some pics of the unit and post later today.

No worries, It will all be inspected before being energized.
