3. How to use
• 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 (e .g . jet regulators and shower heads)
should be unscrewed and cleaned at regular intervals . Every three years, the electri-
cal and plumbing components should be inspected by an authorised professional in
order to ensure proper functioning and operational safety at all times .
Cleaning and maintenance
This instantaneous water heater features an automatic air bubble protection to prevent
it from inadvertently running dry . Nevertheless, 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 re-vented 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 re-connect 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 .
