3. Appliance description
The hydraulically controlled instantaneous water heater heats the
water as it flows through the appliance. When a tap is opened,
the appliance starts heating automatically at the selected output as
soon as the start-up volume is exceeded (see chapter "Installation /
Specification / Data table"). You can adjust the hot water volume
and temperature at the tap by mixing in cold water.
You can choose between 2 output stages. Two further output stages
are hydraulically controlled in relation to the flow rate.
The flow meter compensates for pressure fluctuations. The flow
meter ensures largely stable temperatures. The control unit limits
the flow rate, thereby ensuring an adequate increase in the DHW
temperature at all times.
Heating system
The tubular heater heating system has a pressure-tested copper
cylinder. The heating system is suitable for soft water areas (for
application range, see chapter "Installation / Specification / Data
table").

Settings

1
1 Partial load:
This setting is suitable for hand washing at a basin, for ex-
ample. At low flow rates, the appliance starts heating at half
the selected output.
2 Full load:
This setting is suitable for showers and washing up, for ex-
ample. At low flow rates, the appliance starts heating at half
the selected output and at higher flow rates, the full selected
output.

Cleaning, care and maintenance

f Never use abrasive or corrosive cleaning agents. A damp f
cloth is sufficient for cleaning the appliance.
f Check the taps regularly. Limescale deposits at the tap out- f
lets can be removed using commercially available descaling
agents.
Note
If the outlet temperature is not high enough when the
draw-off valve is fully open at full power, then more water
is flowing through the appliance than can be heated by
the heating system (appliance is at its output limit).
f Reduce the water volume at the draw-off valve. f

Material losses
Following an interruption of the water supply, the
appliance must be recommissioned by carrying out the
following steps:
f Disconnect the appliance from the power supply by f
removing the fuses/tripping the MCBs.
f Open the tap for one minute until the appliance and f
its upstream cold water inlet line are free of air.
f Switch the mains power back on again. f
