2. How to use

As soon as you open the hot water tap, the instantaneous water heater
switches on auto matically. When the tap is closed, the appliance automati-
cally switches off.

Cleaning and maintenance

• 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 electrical and plumbing components should be inspected by an
authorised professional in order to ensure proper functioning and opera-
tional safety at all times.

Venting after maintenance work

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 emp-
tied (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 deac-
tivating 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 appli-
ance 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 activat-
ing the fuses) to the instantaneous water heater and screw the jet regula-
tor back in.
5. The appliance activates the heater after approx. 10 seconds of continuous
water flow.
