2.10 Controlling temperature

The supply temperature (probably lower in winter) and
pressure fluctuations can influence the temperature of the
water leaving the tap.
• Turn the valve slowly in the closed direction for higher
temperatures (F1).
• Add cold water for lower temperatures (F2).

• Connect the appliance on the terminal strip in accordance
with the connection schematic.
• Put on the housing cover and push it onto the rear wall of

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:

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.
Switch off the circuit-breakers/fuses or remove the mains
plug.
Remove the flow-rate limiter (H1–H4).
Controlling temperature
Turn the valve slowly in the closed direction for higher
temperatures (F1).
Add cold water for lower temperatures (F2).
Hand over the installation and operating instructions
to the user and explain how the appliance operates.
