2.3 Brief description
The hydraulically controlled, pressurized
Mini-Instantaneous Water Heater DHM is
designed to supply warm water for one tap
only.
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
Useonlypressuretapttings!
Please use jet regulator
A
(10 or 11) depen-
ding on the type of DHM in question).
1.4 Safety instruction
In the case of temperature selection,
water temperatures of over 60 °C
can be reached at the hot water outlet.
Small children should therefore be kept
away from the hot water outlets.
Danger of scalding!
1.5 Important notes
If the water feed of the DHM has
been interrupted - e.g. because of the
danger 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.
1.6 Maintenance and care
Maintenance work, such as for ex-
ample checking the electrical safety,
mayonlybecarriedoutbyaqualied
installer.
A damp cloth is sufficient for care of the unit.
Do not use any abrasive or corrosive cleaning
agents.
Please de-scale or replace the enclosed jet

1.1 Unit description
The hydraulically controlled pressurized Mini-
Instantaneous 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 capa-
city, and the flow rate.
1.2 The most important
points in brief
Temperature adjustment is effected using
thetting:
– To increase the temperature, restrict
theowratealittle.
– Forlowtemperatures,increasetheow
rate or mix in cold water.
1.3 Hot water output

2.2 Important information
Air in the cold water pipe will destroy
the bare-wire heating system of the
DHM. If the water supply to the DHM has
been interrupted, for example due to the
risk of frost or work on the water pipe, the
following 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.
