Mounting:
* If you still have not, consider buying the shower head and the cord to complete!
* If you are replacing a pre-existing device (in my case):
- Shut off the water (obvious but in case ^ - ^)
- Loosen (using a wrench and a good grip) current device
- Compare the distance between two water inlets hot / cold your old device and the new. If there is a difference, the supplied adapter can address them in a spectrum of several cms, simply by rotating one or both ends (turn they depart or approach).
- Fit the new device (make sure to present it in a good way), optionally provided adapter connector, and tighten (loudly or it will leak!)
If you have a minimum habit of tinkering it will take you about 10 minutes! If you use a professional it should not take him more, but there will be travel costs, time spent, expenses, short, rather find a handyman around you, it's really very simple.
Note: The first assembly gave a very surprising result, with a trickle of water (at perfect temperature admittedly) that flowed pitifully in the shower. After careful consideration of the handyman, the device was removed, examined and a small tip was removed - the one that allows saving water but is not necessary, or even too much, if the pressure in your home is low . The flow is back to normal.
Finally, to use the product keeps its promises: perfect!
