1. Operating instructions
1.1 Unit description
The DNM hydraulically controlled open (non
pressure-type) mini-instantaneos water heater
is designed to heat water for one draw off
point. When the draw-off fitting is opened,
the heating capacity switches on automatically
and the water is heated. The hot water output
is dependent on the cold water temperature,
the heating capacity, and the flow rate.
1.2 The most important points in
brief
Temperature adjustment is effected using
the fitting:
– To increase the temperature, restrict the
flow rate a little.
– For low temperatures, increase the flow
rate or mix in cold water.
1.3 Hot water output
Type Output
by 230 V
DNM 3 3,5 kW
DNM 4 4,4 kW
DNM 6 5,7 kW
* The built-in automatic flow regulation pro-
vides a constant flow rate. Temperature incre-
ase of about 25 K.
1.4 Safety instruction
Danger of scalding!
In the case of temperature selection,
water temperatures of over 60 °C can be re-
ached at the hot water outlet.

for the user and the qualified installer
Risk of injury!
Where children or persons with limi-
ted physical, sensory or mental capabilities
are to be allowed to control this appliance,
ensure that this will only happen under su-
pervision or after appropriate instructions by
a person responsible for their safety.
Children should be supervised to ensure that
they never play with the appliance.
1.5 Important notes
If the water feed of the DNM 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.
The mini-instantaneous water heater must
hot water out-
not be connected to any pressure. Never
put*
close off the fitting outlet and do not use an
2,0 l/min
aerator or a hose with a jet regulator. Furring
can close off the outlet and thus cause the
2,5 l/min
mini-instantaneous water heater to be under
3,3 l/min
pressure.
It is important that only the enclosed jet re-
gulator is used.
1.6 Maintenance and care
Maintenance work, such as for exam-
ple checking the electrical safety, may
only be carried out by a qualified installer.
A damp cloth is sufficient for care of the unit.
Do not use any abrasive or corrosive cleaning
agents.

2.2 Important information
Air in the cold water pipe will destroy
the bare-wire heating system of the
DNM. If the water supply to the DNM has
been interrupted, for example due to the risk
of frost or work on the water pipe, the fol-
lowing steps must be carried out before the
system is used again:
1. Disconnect supply or disconnect the fuses.
2. Open a hot water tap downstream of the
device for as long as it is necessary for
the device and the cold water pipe to be
freed of air.
3. Reconnect the supply or connect the fuses
again.
– All information in these Instructions for
Use and Installation must be followed
carefully. They provide important infor-
mation with regard to safety, operation,
installation, and maintenance of the de-
vice.
Please de-scale or replace the enclosed jet
regulator „SR" regularly DNM 3 / DNM 4:

Scale built up (furring) can close off the outlet
and impair (or even destroy) the appliance.

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 qualified in-
staller for his attention.
2.3 Brief description
The hydraulically controlled open (non
pressure-type) instantaneous water heater
DNM is designed to heat cold water for one
draw off point.
The unit is suitable for hand wash basins, for
example in guest WC's, and for under-sink
and over-sink installation.
The bare-wire heating system is suitable
for low-lime and limy water (see Table 2 for
ranges of use).
2.4 Fittings
Only non pressurised taps can be used for this
appliance.
Please use jet regulator A (10 or 11)
ding on the type of DNM in question).
