Initial rinsing

• Open the warm water tap and allow water to flow for at least
1 minute (flow-rate at least 2 litres per minute). Only then
(for safety reasons) will the appliance begin to heat.
Info: The appliance will not heat if the dispensed water flow is
interrupted prematurely. Open the warm water tap again and
allow water to flow for at least 1 minute.
Tip: Should the appliance not start because of a reduced flow-
rate, remove the perlator, aerator or similar before starting and
repeating the process.
Important: If the continuous-flow heater does not have
sufficient water flow due to low water line pressure in your
domestic plumbing system:
• Switch off the circuit-breakers/fuses or remove the mains
plug.
• Remove the flow-rate limiter (H1–H4).

The supply temperature (probably lower in winter) and
pressure fluctuations can influence the temperature of the
water leaving the tap (see Fig. 4, left: pressurised [closed],
