COMISSIONING
1. Please flush the system through completely by opening the hot tap on the water heater circuit
furthest away from the heater. Allow all air, and debris to pass before closing the hot tap.
2. Turn on the power supply to the heater.
3. Using the button please turn the heater up to 45
o
C.
4. When set, open as many hot outlets as likely to be used at once on the circuit, and adjust the ball valve
until the temperature output at the taps matches that on the display of the unit. Increase or decrease
the flow until just before the temperature drops, increasing the flow will make the target harder to
achieve, decreasing the flow makes it easier to achieve.
5. This optimises the flow rate for 45
o
C, if you wish to optimise for a different temperature, please set the
device at the required temperature and repeat step 4. REMEMBER: Adjusting the flow to the unit up or
down controls the flow at the tap which makes it easier or harder to achieve the set temperature. This
may require some balancing to achieve the best results for your scenario.
6. The comissioning of your system is now complete.
GENERAL USE
Operation of this unit is simple:
• The heater automatically detects flow, so as soon as a tap is opened the heater will instantly begin to
heat the flow of water in accordance with the settings provided to the heater.
• To control the output temperature of the heater use and buttons to set the target
temperature.
• The LED display will show you the target temperature that has been set on the device.
TOP TIP: If the unit is installed in a cupboard once the temperature has been set the cupboard can be
locked, this prevents the temperature from being changed and makes the product safer for children.
MAINTENANCE
Always turn off the power supply before servicing your unit
To ensure a long lasting and efficient product we recommend the following maintenance regime:
• The filter washer supplied and fitted should be cleaned to reduce any debris build up and ensure good
consistent flow rates.
