How do you switch it to 230-V operation?

Good question. I think 115/230 volt rating is a misprint. It should say 115/120 volt rating. The plug is not a 230 volt plug.

You will need to purchase a step-down transformer to be able to use this with 230 V. If you only use an adapter without changing the voltage, you will burn out the motor. Seems easier to find a drill that uses 230 V natively.

There is a red slide switch on the back panel near the AC connector. It switches from 115 to 230 input voltage. Switch it correctly BEFORE plugging the unit in.

There is a switch on the back of the unit that you can set to either 110v or 230v.

As far as I know there really are no options, the relay switches one leg of the 220v power with with a 2-wire 24v thermostat. If you want to switch 110v instead you need to buy the suffix -120 version. Hope that helps

I'm pretty certain it is only 120V. I did not see a switch or any indication that it can be changed to 240V.

According to the instruction, the unit is rated at 125V, 60Hz. So, 230V, 50Hz would most likely damage the unit.

manual says europe 230 vac 50/60 hz but plug is US style and manual says must be changed

Earl, I am not sure I understand your question. The unit has a switch for either 120 or 230 Volts. Did you want to plug it in to a 12 V system as in an automobile? Or did you hope for an outlet to plug in an auxiliary unit? The unit runs on 120 Volt, 22 Watt AC standard home current. If this does not answer your question, give me more detail and ask me again.

You need to go with the professional switches by ivac rated for 240volts. You will need a "tool" switch and a "vacuum" switch. http://www.amazon.com/gp/aw/d/B004JK90QW/ref=mp_s_a_1_8?qid=1423492153&sr;=8-8π=AC_SX110_SY165_QL70&keywords;=ivac&dpPl;=1&dpID;=41q9Ln77e2L&ref;=plSrch

I didn't check fro 230V, but don't recall having seen a switch or anything to indicate it was a auto-switching.... I'm fairly certain it supports 110V only.....

Roger, there are only two ways to wire it... if it does not read, simply unplug the unit 110 volts and reverse the two wires.

It seems to have an auto switching dc converter. I have used it in Germany (240 volts) with only a plug adapter. I take it you are going to England. While i have not actually used it there, it would be incredible to believe the unit could handle 240 but not 230.

You need a step down transformer--a travel transformer from Amazon could work. The Chugger pump is rated at 1.4 amps and 115 volts which translates to 161 watts of power. You will need to look for a travel power converter that steps your 230 volts AC to 120 volts AC with a power rating about double (about 300 Watts) as to not burn your converter out if pump runs at its maximum power load of 161 watts.

I have not done this but, the directions say to just connect it as a 110 volt system instead of the 220 system and it changes it's self automatically.

No it has no transformer. 230 V in gives 230 V out. You will need a separate transformer.

I'm not quite sure about 230 volts in particular, but I'm from Australia and bought it along with an adaptor so I could plug it into the electrical sockets here, which have a different voltage to the US and it works just fine.
