Instructions for the installer

Heater Positioning and Installation

• The electrical installation of this heater must be approved by your local electricity company.

• 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.

Assembly

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.

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.

Choosing the Heater Position

The heater can be positioned anywhere within the room to be heated.

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.

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.

Tilting Safety, Wall Mounting

Olsberg electric storage heaters must be protected against tipping over. To do this, the heaters are to be fixed to the wall.

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.

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.

As a single-phase connection is only allowed for a heater rating up to 2kW according to Utility Regulations, these heaters must always be connected to three phases.

To connect to a Central Charge Control with "single-

wire control", bridge terminals A2/Z2 and N

Make sure the earth cable is firmly connected.

Charge Control

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.

Thermal Switching Relay

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.

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

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.

30

Commissioning the Heater

Following tests must be carried out before commissioning the heater:

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.

Trouble Shooting Tips

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").

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.

31

Instructions for the user

Operation

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.

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)

Once the set level of heat has been stored, the charge control switches off automatically.

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 fans in the storage heater are 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.

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.

Energy saving tips

• Only heat when necessary.

• 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.

• 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.

• 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.

• 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.

32

Care and Maintenance

• Olsberg heaters have been constructed so that they need only a minimum of maintenance.

• The fans are equipped with self-lubricating bearings. We recommend that the heater be opened from time to time by a qualified installer who can free the heaters from any dust which may have accumulated on the fans 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.

This heater is not intended for operating by persons (including children), with reduced physical, sensory or mental abilities or for lack of experience and/or for lack of knowledge to be used it by a person responsible for their security is supervised or received from instructions like the heater to use.

Children should be supervised, in order to guarantee that they do not play with the heater.

Defects

If the heater does not function correctly, please check the following points:

• 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 fuses for the fans in the distributor box loose or defect?

Instructions for the Installer are to be found under

"Trouble Shooting Tips"

Our after-sales service team is of course always available to help you.

Important Instructions

As the surfaces of the heater cabinet get hot in 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.

Electrical appliances conform to valid safety regulations. Repairs and service to electrical appliances must only be carried out by a competent electrician. Improper repair can mean distinct danger to the user.
