How straightforward is the installation of the Avalon A8, and are special tools or professional help needed?

The Avalon A8 countertop water cooler dispenser with a filter set is easy to set up and doesn't require any kind of DIY or specialist skills. The filter brackets clip onto the back of the machine, and the instructions in the manual are easy to follow. All parts are provided and the most you need are pliers or scissors to cut the PE tubing and to attach the valves to your main water source. There is also a double-headed adapter if you need to run water to another device.
