2hp jbj commercial chiller help

[zdad_2004]

I have a 2hp jbj commercial chiller and I was seeing if anyone could help me in making sure I get it wired correctly. Says it needs 208/230volt power source. I thought I would need a 2 pole breaker and 4 cable wire to install 240 volts. I only see 3 spots on the bottom here to hook up the wires. Any know how this should be hooked up and what I would need? Thanks in advance

When running 220VAC it is only necessary to have 3 wires: 2 hot wires and one ground. You are correct about 2 pole breaker.

Inside the circuit breaker distribution panel, both neutral & ground are on the same bus. There is the fourth leg/wire you were looking for.
