1. Operation instructions

1.1 Description of the appli-
ance
With electric storage heaters, electrically-gen-
erated heat is stored during the economical
off-peak periods at low tariff (depending on
the electricity utility concerned, but in most
cases during the night). This heat is then given
off again, depending on the room tempera-
tures required, in the form of hot air by means
of a blower fan, and to a lesser extent also via
the surface of the appliance.

1.2 Operation

To operate the appliance, first raise the cover
of the control panel (1) located on the front
wall.

features - at a glance
R1
Heat storage (charging) – infinitely
adjustable selector switch
Heat emission (discharge) – infi-
nitely adjustable selector switch for
setting the room temperature (spe-
cial accessory)
ON/OFF switch for heat emission
(special accessory)
Additional heating – ON/OFF
switch for additional heating (special
accessory)

1.2.1 Heat storage

The selector switch R1 is used to determine
the degree of heat storage (charging).
Therefore the kind of operation must be
chosen between manual charge control or
the weather influenced charge control, which
should be in the wiring cabinet (main switch-
ing board ?).
If there is no charging control unit installed
(manual operation), the selector switch should
be adjusted as follows:
16
for the user and the professional
I = Transition period (spring/autumn) - cor-
1
responds to about / of full charge
3
II = Mild winter's day - corresponds to
2
about / of full charge
3
III = Winter's day - corresponds to full
charge
= No charge
Once you have had a short period of time
to get used to the system, you will have the
experience needed to find the right setting for
each situation.
If a charging control unit is already installed
(automatik operation), the selector switch
should be set to Position III. The charging con-
trol unit, which is influenced by the weather
conditions, then takes care of the correct
charging process.
For differential regulation of single storage-
heaters it is possible to adapt the operation
for the charging load manually, if a charge
control already exists.
To do this, refer to the operating and instal-
lation instructions for the charging control
unit, or the group control device.

1.2.2 Heat discharge

Heat emission (discharge) is regulated by
means of a Stiebel Eltron room-temperature-
sensor mounted on the wall or integrated in
the appliance (special accessory).
In this situation the desired room temperature
is to be set, which then automatically regulates
the emission of heat via the blower fan, so
that the room temperature which has been
set will be constantly maintained.
On very cold days, if you are going to be
away, it is recommended that the room
temperature regulator be left switched on
in order to keep the room temperature at
about 10 ºC, for example, so that the room
does not become excessively cold (to protect
against freezing).

1.3 Safety instructions

The appliance must not:
– Be operated in areas which are subject
to the risk of fire or explosion due to
chemicals, dust, gases or vapours;
– Be operated in the immediate vicinity of
pipes or containers which carry or con-
tain combustible or potentially explosive
substances;
– Be operated, at less as the minimum
clearance distances advised.
•
Installation (electrical installation) and first
taking into service and maintenance of this
appliance may only be carried out by an ap-
proved qualified installer, and in accordance
with these instructions.
•
Under no circumstances may be the appli-
ance be operated if work is being carried
out in the room concerned, such as laying,
grinding, sealing, cleaning with petrol, or care
work (spraying, wax polishing) of the floor
or similar areas.
After such work has been carried out, the
room must be allowed to cool sufficiently
before the storage heater is charged.
•
During operation the surface of the heater
and the outcoming air will be hot ( more
than 80°C).
•
If it is intended that children or persons
with restricted physical, sensory, or mental
capacity should operate the appliance, it
must be ensured that this is only done 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.
Danger of burning !
Do not cover the devise!
•
Never leave inflammable, combustible or
heat insulating articles or materials like
clothing, laundry, blankets, newspapers, floor
wax, gasoline, sprays, paints or similar in the
vicinity of the heater.
Do not place anything, especially no laundry
or clothing for drying on the heater. Danger
of fire !
•
B The following minimum distance inter-
vals must be maintained between the appli-
ance for objects of all kinds, such as furni-
ture, drapes, curtains and textiles, or other
combustible or non-combustible materials,
especially with regard to the air outlet grille:
To the air outlet grille
To the right-hand side wall
for combustible items
for non-combustible items ⇒ 70 mm
To the left-hand wall
To the cover
The hot air must be allowed to
emerge without any obstacles.
•
The adhesive notification label provided
with these Instructions for Use and Instal-
lation, „Do not put objects on or lean
against" should be affixed in a clearly visible
place on the cover of the appliance in any
areas used for commercial purposes, such
as hotels, holiday homes, schools, etc.

1.4 Care and maintenance

In the event of slight brownish discolouration
occurring on the appliance housing, it should
be wiped off as soon as possible with a damp
cloth.
The appliance is to be cleaned when in the
cool state with conventional cleaning agents.
Avoid scouring or abrasive cleaning agents.
Do not spray any cleaning spray into the air
slots.
The blower fan channel behind the air outlet
grille (4) should be checked by a qualified
installer every two years. Slight dirt deposits
may gather there.
Whenever you have the heaters serviced, we
propose to check also the control- and regu-
lations of the heaters. At the latest 10 years
after taking them into work, you must check
the Safety- and Control-Regulations and the
