An appliance designed for 240V absolutely must have a 240V outlet installed for it; there is no way to properly power it with 120V. If you aren't able to install a 240V outlet yourself, you should contact an electrician.
You'll have to install a double-pole breaker in your breaker box. As for the outlet, read the instructions and determine what size outlet (how many amps) you need. For the cables, if it's an air conditioner that requires 120/240V then you'll need a 4 conductor wire. (3 wires plus ground.) If it just requires 240V you'll need a 3 conductor wire. (2 wires plus ground.)
For wire sizes, some recommendations, which exceed the National Electrical Code, are:
15 Amps or less: 12 gauge; 20 Amps or less: 10 gauge; 30 Amps or less: 8 gauge;
40 Amps or less: 6 gauge; 50 Amps or less: 4 gauge.
Again, these values are over-sized but bear in mind that the actual length of the run is very important and must be taken into account when selecting the gauge of wiring to use for a new circuit. Best practice is to check with a licensed electrician or see Table 310.16 in the National Electrical Code.
If you do this work yourself, always turn off the power
at the breaker box/fuse panel BEFORE you attempt to do any work AND
always use an electrician's test meter having metal-tipped probes
(not a simple proximity voltage indicator)
to insure the circuit is, in fact, de-energized.

You would need to use a step-down voltage converter to convert the voltage from 240V to the required voltage for your air conditioner. Additionally, you may need an adapter to convert the outlet from 3 rounded prongs to the configuration that fits your air conditioner's plug. Be sure to check the voltage and plug type compatibility to ensure safe operation.
240V appliances, such as range, dryer, air conditioner.
To locate and clean the drain plug on a portable air conditioner, first, check the user manual for specific instructions. Typically, the drain plug is located at the bottom of the unit. To clean it, unplug the air conditioner, remove the plug, and clean it with a mixture of water and vinegar. Make sure to dry it thoroughly before reinserting it.
Mine had a small rubber plug on the outside, lower edge of the unit.

To install a window air conditioner using a mount kit, follow these steps: Measure the window opening to ensure the air conditioner fits. Attach the mounting brackets to the window sill and frame. Place the air conditioner on the brackets and secure it in place. Use the included hardware to secure the unit to the brackets. Plug in the air conditioner and test it to ensure it is working properly.
The drain plug on an LG air conditioner is typically located at the bottom of the unit and is used to remove excess water that accumulates during the cooling process. This helps prevent water leakage and damage to the unit.

When plugging in your air conditioner, make sure the outlet can handle the power load, use a grounded outlet, avoid using extension cords, and keep the plug and outlet dry. Regularly check for any damage to the plug or cord.
To unplug an air conditioner, first, ensure the unit is turned off for safety. Locate the electrical plug, which is typically found at the back or side of the unit. Grasp the plug firmly and pull it straight out of the outlet without yanking on the cord. Avoid pulling on the cord itself, as this could damage the wiring.
To replace the cord on your air conditioner, follow these steps: Unplug the air conditioner and make sure it is turned off. Remove the old cord by disconnecting it from the unit. Purchase a new cord that is compatible with your air conditioner model. Connect the new cord to the unit following the manufacturer's instructions. Plug in the air conditioner and test to ensure it is working properly. If you are unsure or uncomfortable with the process, consider hiring a professional to replace the cord for you.
