– Check whether the fuses have blown or
MCB activated, and if necessary replace or
reset.
– Check whether the earth leakage device
(RCD) has activated and reset if necessary.
Should the surface of the storage heater
become too hot in mild weather:
2. Installation instructions
Assembly, electrical connection, and first
operation must be carried out by a
competent person, in accordance with these
instructions. The relevant national and regio-
nal regulations, e.g. I.E.E.Regulations, must be
observed.
2.1 Unit structure
1 Top cover
2 Front/side panel
3 Inner front panel with thermal insulation
4 Heat storage bricks
5 Heating element
6 Feet
7 Air flap
8 Bimetal strip
9 Cable clamp
10 Output control knob
11 Charge control knob
12 Polystyrene protection pieces
13 Polystyrene packaging pieces
14 Mains electricity connections terminal
block
15 Sensor holder
16 Wallbracket
F1 Input charge regulator
F2 Self-resetting thermal cut-out
F3 Non-self-resetting thermal cut-out
2.1.1 Mode of operation
Charging
The heater should be permanently wired to
a dedicated off-peak electricity supply.
The commencement and duration of the
charging period are determined by the
electricity supply company.
ETC 170-340 A/M
The amount of heat stored is adjusted by using
the input charge regulator F1 (See section
1.2.1 for setting instructions). The storage
heater is protected against overheating by a
built-in protective self-resetting thermal cut-
out (F2). Following any activation of the
protective self-resetting thermal cut-out
which may occur, it resets itself when the
temperature has fallen.
Should the protective self-resetting thermal
cut-out fail, the unit is isolated from the
mains by the non-self-resetting thermal cut-
out (F3).
ETC 85 M
This heater has no adjustable controls. The
amount of charge is controlled by the input
charge regulator (F1) which is preset at the
factory. This device also protects the unit
against overheating.
– Check whether the output control knob
(10) is in the min. position, if not, readjust
to a lower setting.
If, after doing this, there is no discernable
change in the state of the storage heater the
following day, the unit should be checked by a
competent person.
(for the professional)
Should the input charge regulator fail, the
unit is isolated from the mains by the safety
thermal cut-out (F3).
Discharging (not applicable to ETC 85 M)
The stored heat is emitted into the room via
the casing surface and the air outlet grille of
the heater. The discharge air flow through the
unit can be altered by means of an adjustable
air flap (7) that is sited above the storage
unit core. A bimetal strip (8) continuously
determines the air outlet temperature.
If an unacceptably high air outlet temperature
arises at the air outlet grille, the bimetal strip
moves the air flap to the „closed" position, so
that the air outlet temperature falls.
2.2 Regulations and provisions
– The relevant national and regional
regulations, e.g. I.E.E. Regulations, are to be
observed.
– The information on the heater rating plate
should be noted. The stated voltage must
correspond to the mains voltage.
– All electrical connection and installation
work must be carried out in accordance
with the provisions and regulations of the
relevant electricity supply company.
– It must be possible to isolate the unit from
the mains on all poles via an additional
device, e.g. switched spur, with an air gap of
at least 3 mm.
– The circuit layout and electrical connection
data for the heater can be seen in the
circuit diagram in these installation
instructions.
– The mains electricity connection cable
must be secured with the cable clamp.
– The Building Regulations relevant to the
area of installation be taken into account.
– Care must be taken to ensure that the
securing wall and the floor have a high
temperature resistance factor.
Under no circumstances should the
air inlets under the heater be
obstructed
It is important to ensure that the
connection of the protective earth
conductor is sound and tight!
2.3 Installation location
The unit must not be
– operated in rooms which are subject to
a fire or explosion risk on account of
chemicals, dust, gases or vapours;
1.6 Important notes
Keep these instructions carefully and
hand them to the new owner in the
event of a change in ownership.
If any repair work has been undertaken
make sure that the competent person is
aware of it.
– operated in the immediate vicinity of
conduits or receptacles which convey or
contain flammable materials or materials
which are subject to an explosion risk;
– be operated if the minimum distances
from neighbouring object surfaces are
fallen short of.
In workshops or other rooms in which
waste gases, oil and petrol smells etc. occur
or where work is carried out with solvents
and chemicals, longer-term nuisance caused
by smells and possibly soiling can arise.
Care is to be taken that
– The floor where the heater is to be fitted
has a sufficient load bearing capacity. In
case of doubt, a building specialist is to be
consulted.
– The floor area is sound and level, so that
the heater will not distort after the bricks
have been fitted and will not cause any
creaking noises.
The unit is not designed to withstand an ad-
ditional vertical load.
2.4 Fixing
Fixing is to be undertaken with wall fixing
components (e.g. dowel and screw or wall
bolts) that are suitable for the type and
construction of the wall. You should satisfy
yourself that the wall is actually suitable for
the fixing process.
2.4.1 Assembly
When disassembling the individual
unit parts of the heater remember
which screws have the shake-proof
washers - these will have to be used when
the heater is reassembled!
– Unpack the heater (fig C ) .
Leave the lower expanded polystyrene
corners (12) on the heater to protect it
and to help with its stability whilst the
following work is undertaken.
– Remove screws at the back of the top
cover (1) and the sides of the front / side
cover (2) as indicated in fig C .
– Pull the top cover (1) slightly forward and
lift upwards, (fig D ). Take care not to
damage the limiters. (The top cover should
pull up without any resistance);
– Remove front panel (2, fig E ).
Lift the heater out of the expanded
polystyrene pieces (12) and lay the heater
down on the expanded polystyrene
packaging pieces (13). Remove screws at
the bottom of the front panel.
