Venting after maintenance work
This instantaneous water heater features an automatic air bubble pro-
tection 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.
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 operational safety at all times.
This instantaneous water heater was manufactured conscientiously and checked several times
before delivery. Should malfunctions nevertheless occur, it is usually only due to a bagatelle. First
attempt to switch the house fuses off and on again in order to reset the electronics. Next, try to
remedy the problem with reference to the following table. In doing so, you will avoid unnecessary
expense of customer service assistance.
