Selecting the temperature indicator
You can choose to display the temperature in °C or °F, as required.
f Turn the temperature selector anti-clockwise, past the OFF f
indicator and another five complete turns, until you find
yourself in temperature unit selection mode. Then select the
temperature unit using the temperature selector. After 30
seconds, the appliance exits selection mode automatically
and the selected temperature unit is retained.
Note
If the outlet temperature is not high enough when the
draw-off valve is fully open and the temperature selector
is set to maximum, then more water is flowing through
the appliance than can be heated by the heating system
(appliance working at maximum output).
f Reduce the water volume until the preferred tem- f
perature delivery is achieved.

Recommended settings

Your instantaneous water heater offers maximum precision and
maximum convenience in DHW provision. Should you nonetheless
be operating the appliance with a thermostatic valve, we recom-
mend that you:
f Adjust the set temperature on the appliance to over 50 °C. f
Then set the required set temperature on the thermostatic
valve.
Saving energy
The following recommended settings will result in the lowest en-
ergy consumption:
- 38 °C for hand washbasins, showers, bath
- 55 °C for kitchen sinks
Internal anti-scalding protection (qualified contractors)
If required, the qualified contractor can set a permanent temper-
ature limit, for example in nurseries, hospitals etc.
When supplying a shower, the temperature setting range must be
limited by the qualified contractor to 43 °C.
Limiting it in this way prevents water from flowing out of the
appliance at temperatures which could cause injury.
Recommended setting for operation with a thermostatic valve
and water preheated by solar energy
f Set the temperature at the appliance to the maximum f
temperature.
Following an interruption to the water supply
Material losses
!
To ensure that the bare wire heating system is not dam-
aged following an interruption to the water supply, the
appliance must be restarted taking the following steps.
f Disconnect the appliance from the power supply by f
removing the fuses/tripping the MCBs.
f Open the tap for one minute until the appliance and f
its upstream cold water inlet line are free of air.
f Switch the power back ON. f

Cleaning, care and maintenance

f Never use abrasive or corrosive cleaning agents. A damp f
cloth is sufficient for cleaning the appliance.

lets can be removed using commercially available descaling
agents.
