1. Operating instructions

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 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
DHM 3 3,5 kW
DHM 4 4,4 kW
DHM 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
reached at the hot water outlet.
Risk of injury!
!
Where children or persons with
limited physical, sensory or mental
capabilities are to be allowed to control this
appliance, ensure that this will only happen
under supervision or after appropriate

!
been interrupted - e.g. because of the
danger of frost or work on the water pipe,
hot water out-
the following steps must be taken before the
put*
unit is brought back into operation:
1. Remove or switch off fuses.
2,0 l/min
2. Open a tap downstream of the unit until
2,5 l/min
the unit and the cold water feed pipe are
3,3 l/min free of air.
3. Replace or switch on fuses again.
for the qualified installer

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 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.
