1 Flo device
The heart of our system. Installed on your main water supply line, Flo monitors water flow, pressure, and temperature in real time, runs automatic Health Tests to detect vulnerabilities, and can automatically shut-off the water if a problem is detected.
2 Threaded brass tailpieces
These brass tailpieces will be used to connect your Flo device to your water supply line. In the instance that you need to remove your Flo device, these will also be used to connect the Spacer.
3 Power supply
Flo requires a 12v power supply and the cord has a water resistant seal. Make sure to push the connector all the way into the device to ensure it has a good connection and seal.
4 Spare O-Rings
These rings help seal the deal with Flo. When installing the device make sure these are properly lubed and placed to create a seal between the device and your connection hardware.
5 Spacer
The spacer can be used during the installation process to ensure there’s no damage caused to the Flo device while fitting and leveling the pipes. It can also be used to replace the Flo unit in the instance that there’s a malfunction or issue with the device and to allow for normal water usage to the home. So make sure to hang on to it!
6 Hex key
The hex key can be used to manually shut-off/on the water supply. Place the key all the way into the green knob on the top of the device and push down until the knob won’t go down any further, then turn 90 degrees to the closed/open position.
