I’ve copied pasted this from another site. Looks like it’s just plugin and go. Installation is probably unpacking it, moving it to position, levelling it, plunging in, checking everything works. How to Install a Condenser Dryer
A great benefit of condenser dryers vs vented dryers is that condenser tumble dryers can be installed anywhere. This is because, unlike vented dryers, they don’t need a hose attachment to vent moisture outside. This means that all you need to do is fit the tumble dryer close enough to a power supply for you to plug the dryer in.
You’ll also need to make sure that the space you’re installing the tumble dryer into is big enough for the dryer and leaves a small gap around the edge for ventilation.
Once the tumble dryer is in place and plugged it, switch it on to make sure everything is working as it should. If the machine isn’t working correctly, check the plug to make sure it’s inserted properly.
If the dryer isn’t working properly, or switching on at all, contact your manufacturer or retailer for assistance.
If you’re placing a tumble dryer next to other appliances, be mindful that they use warm air, therefore placing a tumble dryer next to a fridge or freezer will cause them to work harder
