2. Safety
2.1 Intended use
This appliance is intended for domestic use. It can be used safely by untrained persons. The appliance can also be used in a non-do­mestic environment, e.g. in a small business, as long as it is used in the same way.
This pressure appliance is designed to heat DHW. The appliance can supply one or more draw-off points.
Any other use beyond that described shall be deemed inappropri­ate. Observation of these instructions and of instructions for any accessories used is also part of the correct use of this appliance.
2.2 General safety instructions
CAUTION Burns During operation, the tap can reach temperatures in ex­cess of 60°C. There is a risk of scalding at outlet temperatures in ex­cess of 43°C.
!
WARNING Injury The appliance may be used by children aged3 and up and persons with reduced physical, sensory or mental capa­bilities or a lack of experience and know-how, provided that they are supervised or they have been instructed on how to use the appliance safely and have understood the resulting risks. Children must never play with the appliance. Children must never clean the appliance or perform user maintenance unless they are supervised.
!
Material losses
Protect the appliance and its tap against frost.
2.3 Test symbols
See type plate on the appliance.
3. Appliance description
The hydraulically controlled instantaneous water heater heats 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. In addition, 2 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").
4. Settings
D0000042703
1 2
1 Partial load:
This setting is suitable for hand washing at a basin, for ex­ample. At low flow rates, the appliance starts heating at half the selected output.
2 Full load:
This setting is suitable for baths, showers and washing up, for example. At low flow rates, the appliance starts heating at half the selected output and at higher flow rates, the full selected output.
Click the output selector into the required position.
For start volumes, see chapter "Specification/ Data table/ On".
Recommended settings when using a thermostatic valve
Set the output selector to full power.
4.1 Recommended tap/valve settings
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).
Reduce the water volume at the draw-off valve.
Low draw-off rate = high outlet temperature High draw-off rate = low outlet temperature

OPERATION
Cleaning, care and maintenance
ENGLISH
www.stiebel-eltron.com DHF-C | 21
Following an interruption of the water supply
!
Material losses
Following an interruption of the water supply, the appliance must be recommissioned by carrying out the following steps:
Disconnect the appliance from the power supply by
removing the fuses/tripping the MCBs.
Open the tap for one minute until the appliance and
its upstream cold water inlet line are free of air.
Switch the mains power back ON again.
5. Cleaning, care and maintenance
Never use abrasive or corrosive cleaning agents. A damp
cloth is sufficient for cleaning the appliance.
Check the taps regularly. Limescale deposits at the spouts
can be removed using commercially available descaling agents.
6. Troubleshooting
Problem Cause Remedy
The appliance will not start despite the DHW valve being fully open.
There is no power.
Check the fuses/MCBs in your fuse box/distribu­tion panel.
The flow rate is too low for the appliance to start heating at the selected output. The aerator in the tap or the shower head is scaled up or con­taminated.
Clean and/or descale the aerator or shower head.
If you cannot remedy the fault, notify your qualified contractor. To facilitate and speed up your enquiry, please provide the serial number from the type plate (000000-0000-00000):
