4. User Instructions
The heater must be filled with water before connection to the electrical supply.
When powering up for the first time, you must verify that the temperature
indicator (light) extinguishes when the required temperature is reached.
The heater only switches on again if the temperature falls below this setting.
When filling for the first time, the hot water valve in the low-pressure tap fitting
must be open so that water can flow into the heater. If the heater is not filled with
water before the element is operated, the automatic safety heater may activate
and switch off the appliance. (See trouble shooting for further details).
Temperature setting
Cold; heater is switched off.
Frost protection: the device switches on if the water
temperature falls below 7°C.
Heats water to approx. 32°C.
Economy position: Heats water to approx. 55°C.
Max. temperature approx. 75°C.
Operating the unit at a lower temperature can reduce
scaling, save energy and reduce the risk of scalding.
To use the device, simply select the desired temperature setting from the listed options.
Once a setting is selected the indicator light will illuminate to signal the element is heating
the stored water to the desired temperature. When the light extinguishes the temperature
setting has been achieved. When reducing the temperature setting of the heater, it will
not take effect until the water has cooled below the new temperature set point.
