Took heating element cover off, it have 3 heating element 500 watts each, all of them are wired to one power switch.
The new version of this unit, have two heating element wired to one switch, and 3rd heating element wire to 2nd switch.
As I am going to connect it to PID controller, I probably will be better to connect the 3 to it.
Gotten huge spare part box, 8 heating elements, 2 motors, 3 barring, one gear box, and bunch of switches.
This is the first unit sent to the USA. Serial number is #001
