Stiebel Eltron DHF 15 C [12/52] Operating instructions

1.5 Setting recommendation

# Operation with twin-handle fitting:

" Wash basin:

Half heating output, select !.

" Bath, shower or sink:

Maximum heating output, select !!.

If in spite of the hot water tap being

fully open the temperature is too high,

cold water must be mixed in.

# Operation with one-hand mixer:

" Wash basin:

Half heating output, select !.

" Bath, shower or sink:

Maximum heating output, select !!.

– Turn lever of fitting fully to ”hot”.

– Fully open fitting

– Increase temperature by slowly closing

the fitting

– Reduce temperature by mixing in cold

water or, if possible by opening the

fitting further.

# Operation with thermostatic fitting:

" Maximum heating output, select !!.

– Follow the instructions of the fitting

manufacturer.

1.6 First actions to be taken

in the event of malfunc-

tion

" Check the fuses

" Check the fittings and shower heads for

lime scale blockage or dirt accumulation.

See also ”3. Fault finding by the user”.

1.7 Maintenance and care

Maintenance work, such as for

example checking the electrical

safety, may only be carried out by a quali-

fied installer.

A damp cloth is sufficient for care of the unit.

Do not use any abrasive or corrosive clean-

ing agents.

1.8 Operating and installa-

tion instructions

Keep these instructions carefully and

pass them on to your successor in

the event of a change in ownership, in the

event of maintenance and possible repair

work they should be passed to the quali-

fied installer for his attention.

1.3 Important instruction

In the case of temperature selection,

water temperatures of over 55 °C

can be reached at the hot water outlet.

High temperatures can be achieved if the

unit is switched off and then on again

quickly. Small children should therefore be

kept away from the hot water outlets.

Danger of scalding!

If the water feed of the DHF ... C has

been interrupted - e.g. because of the dan-

ger of frost or work on the water pipe, the

following steps must be taken before the

unit is brought back into operation:

1. Remove or switch off fuses.

2. Open a tap downstream of the unit

until the unit and the cold water feed

pipe are free of air.

3. Replace or switch on fuses again.

1.4 Hot water output

According to the time of year, the following

maximum mixed water quantities or outlet

quantities are delivered, in the case of various

cold water temperatures (see Table 1):

= cold water feed temperature

= mixed water temperature

= outlet temperature.

" Useful temperature:

– approx. 38 °C: e.g. for showers, hand was-

hing, bathing etc.

– approx. 55 °C: for dishwashing and when

using thermostatic fittings.

1.1 Unit description

The hydraulically controlled instantaneous

water heater DHF … C compact control

heats the water as it is flowing through the

unit. As soon as a hot water tap is turned on,

the heating output is switched on

automatically after the switch-on quantity is

exceeded. The temperature of the hot water

is dependent on the flow rate and

temperature of the incoming cold water.

1.2 The main points in brief

Output selector

! Half heating output

Only half the heating output is switched

on:

" suitable e.g. for hand washing.

!! Maximum heating output

With a low flow rate half the heating

output is switched on, at a higher flow

rate the full heating output is

automatically switched on:

" suitable e.g. for bathing, showering or

washing up.

Low tap quantity

" high outlet temperature.

High tap quantity

" low outlet temperature.

If with the tap fully opened the required

outlet temperature is not reached, more

water is flowing through the unit than the

heating element can heat (output limit 12,

13, 15, 18, 21 or 24 kW). In this case the

water quantity at the hot water tap must

be reduced accordingly.

At outlet temperatures of over 43 °C

there is a risk of scalding.
