Microfuse 5x20mm 2Amps. slow
The electronic charge controller is fitted with
a replaceable fuse in the circuit to provide
additional protection.
The fuse is located in a two piece fuse holder
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 respected.
•
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
adjacent surfaces are to maintained B.
•
All electrical connection and installation
work is to be carried out in accordance with
VDE specifications (0100), the instructions
issued by the particular electricity utility
company concerned, and the relevant nati-
onal and regional regulations.
•
The appliance must be capable of being
isolated at all poles from the mains
network by means of an additional device
with a circuit sever of at least 3 mm. To do
this, contactors, fuses, and similar elements
may be used.
•
Any subsequent increase to the connected
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 supply
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
must accord with the mains voltage.
•
The appliance must be secured in order to
fulfil the VDE (Association of German
Electrical Engineers) requirements for
stability.

2.4 Installation
In order to accord with the „EN" requirement
for stability, the heat storage device must be
secured by a wall or floor securing element D .
For fixing the heater to the wall, a screw-hole
can be found in the back panel within the
switching area, through which the heater
must be screwed and secured against the
wall to avoid it tipping over.
Alternatively fix the heater to the floor or to
the stands with 4 screws through the screw-
holes with a 9 mm diameter in the feet of
the heater. (the air-outlet grill and the air-inlet
grill must be removed first.)
The screws and dowels required for securing
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 ma-
terial of which the wall is constructed.
2.4.1 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
contain combustible or potentially explo-
sive 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
involving solvents and chemicals, there is a
risk of sustained odour burdens being eng-
endered, and possibly of dirt contamination
occurring.
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.
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.
2.4.2 Floor-free Heater Installation
with wall fixing brackets
Before installing the heater two wall brackets
(17) must be screwed to
the wall taking into account the safety
distances (dimensions see „technical data"
page 18).
In this case the following must be observed:
The wall fixing bracket can only be used if a
suitable load-bearing wall is available.
ETW 120 - 360 = floor clearance possible
only with wall fixing brackets;
ETW 420 - 480 = floor clearance only
possible if used with the stand console and
wall fixing brackets (optional accessory).
If the wall is not suitable for heavy loads, the
stand console (optional accessory) must be
used in addition to the wall fixing bracket, for
all appliances.
2.4.3 Installation with floor stands
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]).
2.5 Installation of heater E - J
Before securing the appliance, care is to be
taken to ensure that the permissible
minimum distance intervals to adjacent
surfaces are maintained.
The two wall brackets at the back panel of
the heater must be unsrewed before the
installation of the heater begins.
⇒ Unscrew the air outlet grille (5) and take
it out, together with the air intake grille (6);
⇒ Unscrew the front wall (4) in each case at
the lower edge, pivot it forwards, and
detach it at the upper edge by raising it
slightly;
⇒ Unscrew the inner front wall (8) from
side panels, pull the upper part forwards
and lift out;
⇒ Raise the right-hand side wall element (3)
slightly and take it off;
⇒ Guide the mains connection leads and
connection leads for the charging and
discharging regulator through the
aperture in the rear wall of the appliance
(15) into the device, and connect it, taking
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 panel);
⇒ Installed appliance according Point 2.4;
⇒ Remove the cover plate (10) and the
cardboard 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.
Insert storage blocks K - L
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 (9), 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 heating
element, and is pushed onto the right and
rear thermal insulation. The longitudinal 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 (10), drawn out
of the interior, over the upper storage blocks.
2.5.1 Electrical connection
The electrical connection for the heating
elements can be provided with 400 V three-
phase current (Y) or AC, 230 V 50 Hz.
