Setting up the Dyson Link app
Check that the purifier is plugged in.
It must remain plugged in throughout this process.
Ensure your router is connected to the wall socket and you have good signal strength.
Download the latest version of the Dyson Link app from your device's app store or marketplace. The Dyson Link App is available on the Apple App Store for iOS devices and the Google Play store for Android devices.
NB: You will be unable to download the app if you are not running a compatible version of your phone/tablet's operating system. iOS 6 or later is required for iOS devices and Android 4.0 or later for Android devices.
If you are part way through the set up and have a problem, switch the purifier off, sign out of the app and start the process from the beginning.
