1. Operating Instructions
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
order no. see 1.7 „Special accessories".
• The "thermostop" function (thermal sepa-
ration) prevents heating of the tempering
fitting in standby mode.
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
E
= 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!
• Keep children and the disabled (physi-
cal/mental) away from this unit unless they
1
are supervised by a person responsible for
their safety or have been given instructions
on how to use it.
• Ensure that children do not adjust the tem-
perature (to a high temperature) on the unit
when playing -
• We recommend the use of the temperature
restrictor set by the engineer, unless abso-
lutely necessary otherwise.
• To avoid risk of accidental resetting of the
protective temperature restrictor in the event
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
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.

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
