The contactor needs a control circuit do you have this in place.

What starts and stops the pump? Did it not come with its own control gear?

Yes the pump has it's own pre-wired control float. There is also a separate float to indicate high level, which I've wired into an alarm unit..

Ok, and what exactly is it that you have there, is it a DOL starter or just the contractor and overload?

You should have the schematic for it included in the instructions then.

Just don't forget to adapt it for single phase operation

I can't make any sense of the schematic, or which one of the ones shown to use. Hence my request for help here

I'm surprised the contractor isn't pre wired into the control panel with the float switches. That said the schematic included should state how to configure the contractor within the circuit. Just make sure the overload is set correctly or could have to fish a burnt motor out of a load of s***.

What model of control panel do you have?

Then perhaps it's time to employ someone who knows what they are doing.

Couldn't find anyone close by willing/able to do it. I wired it up temporarily so that it could be used and decided to ask for help here. If you don't wish to help Dave then why even reply?

Can you show the cover for the contactor.

Colin where abouts are you? Without sounding rude, we're here to advise not step by step tell you. Any spark should be able to figure out that sort of control panel anyway, they're basic compared to others.

Sorry, don't have a pic of the cover. It has a blue reset button which sits over the contactor. Not sure why, because the thermal overload has it's own reset button.

From what the op has said I think the float switch is already connected directly to the pump and doesn't need including in the control circuit of the starter.

I do wish to help, but if you already have the wiring diagram but can't read it then there's nothing I can do except recommend getting an electrician to do it.

Ah yes you are probably correct so they are just suggesting the thermal overload and not a contactor.

Yes, I think a motor protection circuit breaker would have been more suitable than a whole DOL starter.

If you knew how to do it then why not just tell me which connections (they're all marked on the unit in the pic) to put the L/N feed into and which connections to put the L/N pump wires into and which (if any) to link together. Thought that's a pretty straight forward request for someone who is familiar with these?
