1. Operating Instructions
1.1 Description of Unit
• The closed (pressurized) water storage he-
ater keeps the water content permanently
ready at the pre-selected temperature.
• Only tap fittings in conjunction with the
SVMT safety group may be used.
1.2 The most important points
in brief
• Set the desired hot water temperature
using the temperature selector (1)
• An illuminated display (2) indicates that
the unit is heating up.

1.3 Operation

Temperature setting
°C = cold. At this setting the unit is pro-
tected from frost, although this does
not protect the fitting or the water
pipe.
Eco = recommended energy-saving setting
(approx. 60 °C), low limescale formati-
on
82 = max. temperature setting.
Note:
On request, the engineer can set a tempera-
ture limit on the unit (see .8 "First Use") so
that the temperature is fully adjustable up to
this limit.
Heat up time:
If the entire water content is used, the heat up
time is that shown on the diagram.

1.4 Important Note
• The water storage heater is under
1
mains water pressure.
• During heating up, water will drip out of
the safety valve.
If water continues to drip out of the safety
valve after heating up has been completed,
the device must be switched off and depres-
surized, and a qualified installer called.
• The blow-out line of the safety valve must
not be closed.
• With temperature settings over 45 °C, wa-
ter at a high temperature may start flowing
immediately.
• If it is intended that children or people with
restricted physical, sensory, or mental capa-
city are to operate the appliance, they may
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!
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 cause pres-
sure to build up in the heater.
Signs of limescale are boiling sounds and re-

duced water flow. In such a case, the unit and
fitting must be descaled by an engineer.
The thermostat knob may only be removed by
82 °C
an engineer.
All information in these Operating and In-
stallation 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 clea-
ning agents.
