The room temperature is regulated to
about 22 ºC.
Microfuse 5x20mm 2Amps. slow
The electronic charge controller is fitted
with a replaceable fuse in the circuit to pro-
vide additional protection.
The fuse is located in a two piece fuse hold-
er between the X1 and X2 connections.
To access the fuse, the upper section
of the fuse holder must be removed
from its base.
Before changing the fuse the electrical
supply to the appliance must be switched
off.

2.3 Regulations and provisions

•
Take careful note of the enclosure leaflet
in the appliance and accessory pack.
•
The building and garage regulations of
the country concerned are to be respect-
ed.
•
The surface on which the appliance is set
up must have a sufficient load-carrying
capacity.
In case of doubt, a structural surveyor is
to be consulted (see „Technical Data" for
the weights of the storage heaters).
•
The minimum interval distances to adja-
cent surfaces are to maintained B .
•
All electrical connection and installation
work is to be carried out in accordance
with VDE specifications (0100), the in-
structions issued by the particular elec-
tricity utility company concerned, and
the relevant national and regional regula-
tions.
•
The appliance must be capable of being
isolated at all poles from the mains net-
work by means of an additional device
with a circuit sever of at least 3 mm. To
do this, contactors, fuses, and similar ele-
ments may be used.
•
Any subsequent increase to the connect-
ed load must have repeat approval from
the electricity utility company concerned.
If subsequent increase in connected load
is not notified to the utility company, this
will constitute a breach of the power sup-
ply contracts.
•
The operating media are to be designed
to match the rated consumption of the
appliance.
•
The appliance type rating plate is to be
observed carefully. The voltage indicated
20
must accord with the mains voltage.
•
The appliance must be secured in order
to fulfil the VDE (Association of German
Electrical Engineers) requirements for sta-
bility.

2.4 Place of installation

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.
In workshops or other areas in which the
odour of waste gases, oil, petrol, etc. might
occur, or in which work is carried out in-
volving solvents and chemicals, there is
a risk of sustained odour burdens being
engendered, and possibly of dirt contami-
nation occurring.
Installation wall
A check must be made as to whether an
adequately load-bearing securing wall is
available for securing the appliance.
If no suitable securing wall is available, the
device must be secured to the floor (bolted
directly to the floor or secured by means of
a Vario bracket [special accessory]).
Floor
The surface on which the appliance is to
be set up must be even and of sufficient
load-bearing capacity for the housing not
to be moved.
It must be ensured that the securing
wall has a temperature resistance of
at least 85 ºC, and the floor of at least 80 ºC.

2.5 Appliance installation

In order to accord with the VDE require-
ment for stability, the heat storage device
must be secured by a wall or floor securing
element H .
The screws and dowels required for secur-
ing the appliance do not form part of the
scope of supply. They are to be selected
and obtained by a qualified installer on the
basis of the material of which the wall is
constructed.
Securing to the wall
A hole is to be provided in the rear wall of
the appliance, in the area of the switch-
ing elements, through which a suitable
load-bearing screw or bolt is inserted for
the purpose of securing it (for dimensions
see „Technical Data", page 18).
Before securing the appliance, care is to be
taken to ensure that the permissible mini-
mum distance intervals to adjacent surfaces
are maintained.
Securing to the floor
The appliance is secured to the floor by
screwing or bolting the base of the appli-
ance to the floor through 4 holes of 9 mm
diameter.
This securing arrangement can only be car-
ried out if the air outlet and inlet grilles and
the air flow device are removed.
2.5.1 Installation of heater C - H
⇒ Unscrew the air outlet grille (4) and take
it out;
⇒ Pull the air inlet grill (5) of the lower part
forward from the catch spring and take it
off by raising it from the upper lock;
⇒ Unscrew the front wall (3) and the inner
front wall (7) located behind it, in each
case at the lower edge, pivot it forwards,
and detach it at the upper edge by rais-
ing it slightly;
⇒ Raise the right-hand side wall element
(2) slightly and take it off;
⇒ Guide the mains connection leads and
connection leads for the charging and
discharging regulator through the ap-
erture in the rear wall of the appliance
(12) into the device, and connect it, tak-
ing Point 2.5.2 into account (offset the
connection lead by about 260 mm and
shorten it as required, in such a way that
it cannot touch the slots in the side pan-
el);
⇒ Place the appliance at the intended in-
stallation location and screw or bolt it to
the securing wall (with the base securing
to the floor as required).
⇒ Remove the cover plate (9) and the card-
board inserts from the interior. These
must be entirely free of foreign bodies
such as packing residue, etc.
Check the thermal insulation in the
appliance for transport damage, and
replace it if necessary.
I - J
Insert storage blocks
The storage blocks can be used even with
slight transport damage. This will not impair
the operation of the appliance.
To insert the storage blocks (8), the heating
elements (E5) must be slightly raised. The
first storage block with the heating element
trough is laid facing upwards, with a certain
amount of space between it and the right-
hand thermal insulation, beneath the heat-
ing element, and is pushed onto the right
and rear thermal insulation. The longitudi-
nal holes form the heating channels.
When raising the heating elements, take
care to ensure that the transition holes in
the side thermal insulation are not made
wider due to the heating elements.
Finally, slide the cover plate (9), drawn
out of the interior, over the upper storage
blocks.
