Using the appliance after switching off
the water supply
Switch off the appliance (unscrew the fuse in the house elec-
trical installation).
Open the warm water tap and keep it open until the air has
been completely forced out of the water pipe.
Switch the fuse back on again.
The appliance is now ready to operate.
Start-up after power failure
Open the warm water tap fully and allow a minimum water
flow of 6 litres/minute.
Winter operation
Note: It is possible in winter that the supply temperature of the
water is reduced and the required outlet temperature is no longer
achieved.
In order to compensate for this temperature reduction, please
reduce the water quantity on the tap until the required water
temperature is achieved.
Cleaning
Only wipe off the appliance using a moist cloth. Do not use
acidic or abrasive cleaning materials.
Do not use a steam cleaner.
Notes: It is normally not necessary to descale the appliance.
However, extremely hard water and the frequent flows of very hot
water can cause the appliance to scale up. In this case please con-
tact our after-sales service.
Customer Service
We ask you to always provide the E-No. and the FD-No. of your
appliance when calling in a customer service engineer.
You will find the numbers on the inner side of the fold up operat-
ing panel on the continuous-flow heater.
