1. Operating Instructions
for the user and engineer
1.1 Description of Unit
The open (pressure-less) water heater con-
stantly maintains the water content at the
preset temperature.
On heating, the expansion water drips through
the outlet fitting.
Only fittings for open (pressureless) water
heaters may be installed.
We recommend Stiebel Eltron fittings: for or-
der no. see 1.7 "Special accessories".
1.2 The most important points
in brief
• Set the desired hot water temperature
at the temperature selector ( 1)
• The unit is heating when the display ( 2)
lights.

1.3 Operation
Temperature setting
°C = cold. On this setting, the unit, but not
the fitting or water pipe, is protected
from frost
Eco = recommended energy-saving setting
(approx. 60 °C), low limescale forma-
tion
85 = max. temperature setting.
Note:
On request, the engineer can restrict the tem-
perature on the unit (see 2.8 “First Use”) so
that the temperature can be set anywhere up
to the temperature limit.
Heating time:
If the entire water content is used, the heating
time is that shown on the diagram.

1.4 Important Note
• The water heater must not be pres-
surized. Never block the fitting outlet
and do not use a Perlator or hose with jet
controller.
•
If the temperature is set higher than 45 °C,
very hot water can flow immediately!
• If it is intended that children or people
with restricted physical, sensory or mental
capabilities are to operate the appliance,
they must only be permitted to do so after
appropriate instruction has been provided by
the person responsible for their safety.
Children should be supervised to ensure that
they do not play with the device.
Risk of scalding!
•
We recommend the use of the temperature
restrictor set by the engineer, unless abso-
lutely necessary otherwise.
• 2 kW versions: to avoid danger from ac-
cidental resetting of the protective tempera-
ture restrictor in the case of a fault, the unit
must not be connected via a timer switch.
Limescale can block the outlet and hence pres-
surize the heater.
Signs of limescale are boiling sounds and
reduced water flow. In this case have the unit
and fitting descaled by an engineer
On use of a shower fitting (see 1.7 Special Ac-
cessories), regular descaling is necessary (re-
moval of limescale from the spray head).
The thermostat knob may only be removed by
an engineer.
All information in these Operating and Instal-
lation Instructions must be observed. The
instructions contain important information for
safety, operation and maintenance of the unit.
1.5 Care and Maintenance
To clean the unit, simply wipe with a damp
cloth. Do not use abrasive or aggressive clean-
ing agents.
Maintenance work should only be
performed by an engineer.
1.6 What to do if....
...there is no hot water:
Check the thermostat, plug and fuse.
...there is a boiling sound from the unit:
Have the unit and fitting descaled by an en-
gineer.
...see also 3. „Fault repair by the user and
engineer”.
If an engineer is called for a problem, to help
him resolve this more quickly and efficiently,
please give him the information below on the
