Instructions for the installer
Heater Positioning and Installation
Assembly
• The electrical installation of this heater must be
approved by your local electricity company.
The heater should be only removed from its packaging near to its place of final assembly.
Small cracks or chips in the heater core bricks have
no influence on the operation of the heater.
• The installation must be carried out by a competent
electrician.
• Electrical installation and local safety regulations
must also be adhered to.
• If heaters are to be installed in commercial or public buildings such as hotels, holiday homes or
apartments, schools, administrative buildings etc.,
a special warning label is to be attached to the top
of the heater. This label is available from your local
contractor.
Minimum Clearances
For reasons of safety, the following minimum clearances are to be adhered to:
•
From cover and side panels ..........................10cm
•
From air-outlet grille .......................................25cm
Procedures to be followed
All National and Local Safety Codes should be adhered to both at the planning and installation stages.
Tilting Safety, Wall Mounting, Floor Fixing
Olsberg electric storage heaters must be protected
against tipping over. To do this, the heaters are to be
fixed to the wall or to the floor.
Choosing the Heater Position
The heater can be positioned anywhere within the
room to be heated. It is preferable however to place
the heater under a window so that the cold air in this
vicinity can be warmed, causing natural convection.
The floor and/or the wall must be able to take the
weight of the heater. Please, therefore, note carefully
the weights given in the Technical Data section of this
instruction. If in doubt, consult a building engineer or
architect.
Olsberg storage heaters generally need no protective
underboard when standing on normal flooring, as long
as this is flat and smooth and can withstand temperatures of 80°C minimum.
Floorings which do not withstand point loading can
lead to the heater feet subsiding into the flooring, thus
interfering with, or preventing completely, convection
below the heater.
In the case of soft, load-sensitive or non-heat-resistant
floors or carpeting, as well as to even out any surfaces, it is advisable to first put down a protective board
the size of the underside of the heater. When using
high- or thick-pile carpeting a protective board should
definitely be used.
For appliances without integral room thermostats, the
wall-mounted room thermostat should be mounted
preferably on an internal wall, at least 2.5m from the
heater and at a height of approx. 1.5m.
22
The heater should first be mounted to the wall as
shown in Fig.1 using the screw and wall-plug provided. The fixing screw can be threaded through either
the left-hand or right-hand inside panel.
If the heater cannot be fixed to the wall, it is possible
to fix it to the floor itself. 2 drill holes of Ø6.5mm are to
be found in the left and right hand floor of the heater
(Fig.2).
Floor fixing must be carried out using suitable fixing
materials. We recommend hexagonal head screws
(DIN 571) with corresponding washers and floorplugs.

Cover up the non-applicable power ratings on the
heater rating label (bottom right of heater) with
the label provided (in the bag with the wall-fixing
screw) - see example of rating label on page 30.
For this, remove the protective paper from the
adhesive side of the label. Position the adhesive
side on the power rating to be covered by means
of the frame-outline printed on the rating label.
Press the covering label firmly and then remove
the carrier foil. Proceed in the same way for the
second rating to be covered.
Tip: It is easier to cover the rating if the edges of
the label are cut off beforehand or, if the rating label plate is first removed from the
heater.
Fit the top insulation mats tightly onto the cover
bricks. Make sure that the seam of the lower insulation mat faces forward and the seam of the
upper mat faces the rear.
Make certain that the capillary sensor does
not get pulled out of its sleeve.
Put a cross against the chosen rating in the circuit diagrams, both in the Instruction Leaflet, and
in the right hand inside panel.

26
Push the connecting cables on the left-hand inside panel onto the connecting lugs of the heating elements.
6
Make certain that the capillary tubes sit firmly in
the sleeve in the insulation and in the control resistance and that they are not touching any wires
or other live parts
No internal wiring, nor the wires of the powersupply cables should be reachable from outside
through the ventilation slits in the side panel.
7
The heater is then re-assembled as described in
Part 1 on page 24, but in reverse order. When
mounting the right-hand side panel make sure
that the fluff filter does not get jammed so that it
can be changed without problem at a later date
(see "Care and Maintenance" on page 34).
Cable Feed
Fig.3
27
Electrical Connection
The storage heater is connected to element feed
(OFF-PEAK Tariff) and control cables for the room
thermostat and the charge control (A1/Z1; A2/Z2).
You will find the number and type of storage brick
packs in the section "Technical Data" The heater is
suitable for a direct cable feed, it is also suitable for
feeding from a spur junction.
Use at least a heat-resistant PVC cable (H05V2V2-F)
as a load current conductor.
According to regulations every branch circuit must be
individually protected, for instance by circuit breakers
for all phases. These circuit breakers must have contact openings of at least 3mm.
Each storage heater must be connected to its own
separate load-current cable from the distributor panel.
Running cables from heater to heater is not allowed.
To connect to a Central Charge Control with "singlewire control", bridge terminals A2/Z2 and N
Make sure the earth cable is firmly connected.

Charge Control
Thermal Switching Relay
The charge control registers the outside temperature
and converts this value into a control current. This
current is passed via the control wires A1/Z1 and
A2/Z2 to the control resistance in each storage heater.
At the same time, the temperature in the heater core
is also registered. The switch-off point of the charge
thermostat is therefore determined by both the outside
temperature and the temperature of the heater core.
In this way, a control of charge according to the outside temperature and the residual heat in the heater is
achieved, thus complying with Energy Saving Legislation.
The control wires can be run together with cable feeds
L, N and PE.
Please also read the Instruction Leaflet supplied with
the Charge Control.
By installing a thermal switching relay into each storage heater, the Utility relays in the junction box can be
omitted. The thermal relay uses a bimetal strip and
can be classified as a low-noise switch.
Make certain that the installation of a thermal relay
does not violate installation Codes of Practice of your
local Utility.
Please also read the Instruction Leaflet supplied with
the Thermal Switching Relay.
Room Thermostat
The discharge of the storage heaters and thus the
regulation of the room temperature is achieved using
a room thermostat.
The type of thermostat and its configuration is dependent on the heater installation and the requirements of the user.
Please also read the Instruction Leaflet supplied with
the Room Thermostat.
Day-acting Element
Using the day-acting element the heater can give off
warmth immediately even if it is not charged at all.
The day-acting element works on the ON-PEAK Tariff.
Switching and control of the Day-acting Element is to
be carried out using an integral or external room
thermostat suitable for this purpose.
Please also read the Instruction Leaflet supplied with
the Day-acting Element.
Integral Room Thermostat
The integral thermostat is designed for direct mounting to the heater itself:
• Thermo-mechanical room thermostat:
This type of thermostat switches the heater fan ON
or OFF, according to the temperature required.
• Electronic room thermostat:
The speed of the fan is regulated electronically according to the required room temperature.
External Room Thermostat
Following thermostats can be supplied:
• Standard Version
- with illuminated ON/OFF switch
• Comfort- Version
- with DAE switch
- and ON/OFF switch
31
Commissioning the Heater
Trouble Shooting Tips
Following tests must be carried out before commissioning the heater:
Olsberg Storage heaters are equipped with a continuous running charge control and a charge safety nonresetting limit switch. If the charge control does not
switch off the elements under normal charging conditions, the non-resetting safety limit switches off the
power supply to the elements. Problems in this category must only be repaired by a qualified installer (see
Chapter "Important Instructions").
• Insulation test with a voltage of at least 500V. The
dielectric resistance must be at least 0,5MOhm.
• The electrical installer must measure the power
draw of the elements. This can be done using a
kW and time measurement or alternatively by
measuring the cold element resistance.
The value is to be compared with that of the rating
label or in the ‘Technical Data’ Section.
Note:
During the first charging periods the machine oils
various used in manufacture, as well as dust particles accumulated during manufacture and storage burn off, causing an unpleasant odour.
Make certain the room is well ventilated.
Re-assembly
Heaters that have already been in operation or have
been taken apart and repositioned must be reinstalled according to these instructions. The commissioning tests described on this page must also be
carried out.
The first charging cycle after re-assembly must be
monitored by the installer until the charge control
switches off the elements.
Any insulation parts which are, or seem to be, damaged or have changed properties which could influence their function and safety, must be replaced.
If the heater does not work correctly, the following
checks should be undertaken:
1. Heater does not store heat
Check the circuit breakers and relays.
Switch on the Central Charge Control and measure
the control voltage on terminals A1/Z1. A defective
central charge control can lead to continuous voltage
on the control resistance, causing it to heat up so
much, that the heater is always switched off.
Check whether the charge control or non-resetting
safety control has switched off. The safety control is
reactivated by pushing in the activating knob. Possible
causes of the heater switching off are:
- defective charge control thermostat
- prohibited covering of the heater causing hot-spots
2. Heater always goes on full charge
Charge control defect? Heaters that are controlled by
a central charge control should be checked to see that
the control sensor is sitting correctly in the control
resistance. Check that the central charge control is
working and providing voltage to the control resistance. Check the control resistance also. At the
same time, check that the sensor bulb sits correctly in
its sleeve.
3. Heater does not give out enough heat
Heater sized too small. Fan or room temperature control is defective.
The central charge control may also have to be adjusted higher. The special instructions for the respective charge control are to be adhered to.
32
Instructions for the user
Operation
Energy saving tips
The heater operation takes place by means of the
recessed operating knob at the top right of the heater.
By pushing the knob lightly, it will emerge for operation. After adjustment, the knob can be pushed back
into the heater. The knob can be recessed in any adjustment position.
• Only heat when necessary.
Heat Storage
takes place automatically. The amount of residual
heat from the previous day is always taken into account when the heater is charged using the charge
control.
Automatic Central Charge Control
The charge adjusting knob should always be set to
MAX (fully clockwise), at least in rooms that are in
continuous use. If the heater charge in other, lessfrequented rooms is required to be reduced, turn the
adjusting knob slightly anti-clockwise. Remember that
the adjustment only makes itself felt on the following
day(s). Do not, therefore, make too abrupt changes.
The amount of heat stored in the complete installation
is controlled by the Central Charge Control (in the
distributor panel). To adjust this, please refer to the
Instruction Manual supplied with the charge control.
Manual Control
If the heater is not connected to a Central Charge
Control the amount of heater to be stored is determined by adjusting the continuous-run manual charge
knob on the heater as follows:
• No storage: Knob fully left (anti-clockwise)
• Full storage: Knob fully right (clockwise)
• Keep the room temperature at 20°C if possible.
Each degree above 20°C increases the heating
costs by 6 to 7%. Likewise, each degree below
20°C saves the same amount of energy.
• Do not heat only by the radiation from the surfaces
of the heater, but use the fan as well. If necessary,
turn the heater charge adjusting knob slightly down
(anti-clockwise).
• Use an automatic charge control to charge the
heater if possible. Then, the heater will only store
the amount of heat necessary to cover the heat
load for the following day. A correctly adjusted
charge control is a pre-requisite for an economic
operation of the storage heater at comfortable
room temperatures.
• During long periods of absence in the heating season allow the room temperature to sink, but not below 10°C. This saves energy without the risk of the
building cooling out so far as to cause freezing of
pipes, etc.
• Continuous airing of a building by having the windows ajar is too expensive. Short bursts of strong
ventilation by opening windows fully is preferable.
During ventilation, turn the room thermostat adjusting knob to MIN (fully anti-clockwise) so that the
fan does not run.
• If windows and doors are draughty, improve the
draught-excluding seals.
• Close blinds and shutters after dusk, reducing the
loss of heat from the windows.
Once the set level of heat has been stored, the charge
control switches off automatically.
• For reasons of fire safety, full-length curtains and
blinds are not allowed in front of storage heaters.
Apart from that, they reduce the heat-transfer into
the room, increase the losses via the windows and
cause an increase in energy consumption.
Heat Discharge
The control of the heat discharge is by means of a
room thermostat. Once the room temperature falls
below the set level, the fan in the storage heater is
switched on and heat dissipated into the room for
such a period as is necessary to bring the temperature back up to the desired level.
• The building fabric (walls, ceilings, etc.) and also
the furniture in the rooms absorb heat in a delayed
time-frame, store this heat and transfer it back into
the room very slowly. This should be taken into account when setting the room thermostat and also
any night-time set back.
Summer operation
Turn the adjustment knobs both on the heater, and on
the room thermostat to MIN (fully anti-clockwise) during the summer months. Do not turn off the fuse or
circuit-breaker to the central charge control as this can
de-synchronise the charge control timer.
• Floors, ceilings and walls constitute a storage
mass which was taken into account when sizing
the heaters. If the night-time temperature set back
is too drastic, this could lead to a lack of comfort
during the day.
33
Care and Maintenance
• Olsberg heaters have been constructed so that
they need only a minimum of maintenance.
• Olsberg-Heaters are fitted with a fluff filter. The fluff
filter should be cleaned at regular intervals, dependent on the amount of dust in the room (ideally
before each heating season).
Cleaning the filter should only take place on a cold
heater (operating knob at full anti-clockwise position). Push the air-outlet grille to the left. The fluff
filter can now be removed and cleaned or replaced
by a new one (see chapter „Spare filter set“, page
35).
Caution: The fluff filter must be completely dry before it is reinstalled into the heater.
• The fan is equipped with self-lubricating bearings.
We recommend that the heater be opened from
time to time by a qualified installer who can free
the heater from any dust which may have accumulated on the fan or in the air-outlet channels.
• Cleaning and maintenance intervals are dependent
on the conditions under which the heater works.
We recommend that the first check take place at
the latest before the beginning of the second heating period. Further maintenance intervals can then
be individually set.
• We recommend that the control and regulation
elements of the heater also be checked regularly.
All safety, control and regulation elements should
be checked by a qualified installer at the latest 10
years after initial installation. This can save unnecessary energy costs.
• Do not use soft-scrub or other abrasive substances
to clean the surfaces of the heater. Normal household cleaners suffice entirely.

Important Instructions
Defects
• As the surfaces of the heater cabinet get hot in
If the heater does not function correctly, please check
the following points:
use, flammable or other objects presenting a danger of fire must not be placed on, or near the heater.
Do not, therefore, place any wooden objects,
clothes or washing, newspapers, blankets or the
like on or over the heater and do not put any pieces of furniture made of inflammable materials, nor
spray tubes or similar objects closer than
25cm in front of, or on the heater, especially not in
front of the air-outlet grille.
• It is important to remember that the surfaces of
the heater can reach temperatures in excess of
80°C during operation.
• The storage heater is only to be used in rooms
where neither explosive gases (e.g. from floorsealant), nor inflammable dust is present!
If renovation work causing dust accumulations is
taking place the heaters must either be operated
without the fans or switched off altogether.
• Is the heater charge control set to no-charge?
• Is the complete heating system switched off (via
main switch)?
• Are the circuit breakers in the distribution box loose
or defect?
• If the heater cabinet is warm, but the fan is not
running: Is the room thermostat working? Are the
