Special Notes:
Temperature control:
This sensor tap has two pipeline design - direct hot and cold supplies. 
Power Options
DC = Direct Current (Battery source)
AC = Alternate Current (Mains electricity supply)

DC only: The tap can run off batteries only (4 x AA batteries)
We recommend using alkaline batteries, which should be new and of the same brand. 

AC only: The tap can run off Mains power supply only.
A 'step-down' transformer is supplied, type AC220V-240V (with 6V Output)

AC + DC: The tap can run off both AC (Mains) + DC (Batteries) connected at the same time.
This means, AC (Mains supply) will run the tap as normal, while the DC (batteries) ramains dormant, and acts as a backup power should the AC power fails.

It's entirely up to you to decide which power option/combination suits your installation/usage the best.
The integrity of the tap stays the same.

AC+DC Power Option: 
This sensor tap can be powered by either Mains or battery or both (This means that in case of a power cut, it will automatically switch to battery) 
The control box for this sensor tap has a built-in transformer with detachable UK 3-pin AC cable.
Water Supply Feed:
This sensor tap only has a single water supply feed and it's designed to be supplied with pre-mixed water. Consideration should be given to safe hot water delivery and the use of an appropriate temperature reduction device i.e. thermostatic mixer valve. 
Drilling a hole? 
Standard 32mm hole will suffice.
