2. Installation instructions
(for the professional)
1.5 Fault finding
Should the heater fail to become warm:
– Check whether the charging control knob
(
11
) is in the max. position, if not, re-adjust
to the maximum position.
– Check whether the heater is switched on at
the external isolating switch adjacent to the
heater.
– 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 be-
come too hot in mild weather:
– 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.
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.
Assembly, electrical connection, and first ope-
ration must be carried out by a competent
person, in accordance with these instructions.
The relevant national and regional regulations,
e.g. I.E.E.Regulations, must be observed.

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 electri-
city 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 sto-
rage 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 tempera-
ture 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.
Should the input charge regulator fail, the unit
is isolated from the mains by the safety ther-
mal cut-out (
F3
).
Discharging
(not applicable to ETC 85 M)
The stored heat is emitted via the unit‘s
surface and via the outlet grill at the top of
the heater. A bimetallic strip (
8
) continually
determins the air outlet temperature. If the
storage temperature (air outlet temperature)
is low, the heat output can be altered by the
adjustable air flap (
7
) that is sited above the
storage core.
If the air outlet temperature at the air outlet
grill is too high, the bimetallic strip will close
the air outlet flap in any position of the con-
trol knob (
10
) in order to reduce the outlet
temperature. If the storage heater is fully loa-
ded, the air outlet flap is generally closed.
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 tem-
perature resistance factor.
Under no circumstances should the
air inlets under the heater be obs
-
tructed
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 che
-
micals, dust, gases or vapours;
– 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 con-
sulted.
– 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 cre-
aking noises.
The unit is not designed to withstand an addi-
tional 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 cons-
truction 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 cor-
ners (
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 dama-
