To turn one element off turn breakers 1 and 2 or 3 and 4 off while the others are on.
To run full power all 4 breakers on.
To run in series turn breakers 1 and 4 off, leave 2 and 3 on and turn switch on. (WARNING: NEVER turn the switch on while breakers 1 and 4 are on, you'll short across 220 and pop one or all of the breakers up the line). I have a cover over the switch so you cant bump it.
