12. Usage
•
Plastic surfaces and fittings should only be wiped with a damp cloth. Do not use
abrasive or chlorine-based cleaning agents or solvents.
•
For a good water supply, the outlet fittings (special tap aerators and shower
heads) should be unscrewed and cleaned at regular intervals. Every three years,
the electrical and plumbing components should be inspected by an authorised
professional in order to ensure proper functioning and operational safety at all
times.
Cleaning and care
The appliance must be vented before using it for the first time. Each time the
appliance is emptied (e.g. after work on the plumbing system, if there is a risk of
frost or following repair work), the appliance must be revented before it is used
again.
1.
Disconnect the instantaneous water heater from the mains (e.g. via
deactivating the fuses).
2.
Unscrew the jet regulator on the outlet fitting and open the cold water tap
valve to rinse out the water pipe and avoid contaminating the appliance or the
jet regulator.
3. Open and close the hot water tap until no more air emerges from the pipe and
all air has been eliminated from the water heater.
4.
Only then should you reconnect the power supply again (e.g. via activating the
fuses) to the instantaneous water heater and screw the jet regulator back in.
5. The appliance activates the heater after approx. 10 seconds of continuous
water flow.
