radiator to attain its maximum performance ensure that any
furniture or other obstruction is not placed closer than 250mm.

IMPORTANT SAFETY INFORMATION
WARNING - THE SURFACE OF THIS RADIATOR CAN BE HOT.
The surface temperatures of this radiator are within the requirements of EN60-335 the European Standard covering the safety
requirements of electric heating appliances, and momentary contact with any part of the radiator should not cause injury.
However, in order to be effective, radiators of any type do get hot, especially around the air outlet grille.
Therefore, if aged or infirm persons, or young children, are likely to be left unsupervised in the vicinity of a radiator
precautions should be taken to ensure that prolonged contact with the radiator cannot occur. We recommend that a
guard is fitted around the radiator, as is normal with some types of heating appliances in similar circumstances. If you require
further information on these guards, please contact Dimplex Customer Services on 0870 7270 101.
• WARNING - IN ORDER TO AVOID OVERHEATING, DO NOT COVER THE SURFACES OF THE RADIATOR AND DO
NOT OBSTRUCT AIR OUTLET GRILLES Surfaces of the radiator should not be covered or obstructed as this can cause
excessive temperatures that can be hazardous and may cause safety cut-outs to operate. For example, do not put clothes,
fabrics or any combustible materials on the radiator or allow curtains to come within 75mm (3”) of the top and ends of the
radiator. Do not allow furniture to be pushed up against the radiator, a minimum clearance of 150mm is critical for safety,
however to ensure radiator performance is not affected a clearance of 250mm is recommended.
DO NOT PLACE OBJECTS IN CONTACT WITH THE RADIATOR
• WARNING – The radiator must not be located below a socket outlet.
• PLEASE NOTE: THIS RADIATOR IS HEAVY AND MUST BE SECURELY FIXED TO A SOUND WALL. No attempt
should be made to move the radiator without first seeking specialist advice. If you are not happy that the radiator has
been securely fixed, please inform your installer.
UNDER NO CIRCUMSTANCES SHOULD YOU ATTEMPT TO MOVE THE RADIATOR OR LOOSEN WALL FIXINGS
WITHOUT FIRST REMOVING ALL ENERGY RETENTION CELLS FROM THE RADIATOR.
• DO NOT SIT OR STAND ON THE RADIATOR.
• DO NOT SPILL LIQUIDS ONTO THE APPLIANCE. IF YOU DO, SWITCH THE RADIATOR OFF AND GET A QUALIFIED
ELECTRICIAN TO CHECK IT.
• DO NOT POKE OBJECTS THROUGH THE GRILLE.
• DO NOT PLACE OBJECTS IN THE SPACE BEHIND THE RADIATOR.
• DO NOT USE POLISHES ON THE RADIATOR OR ON FURNITURE NEAR TO IT. The hot interior of the radiator can
produce paraffin smells from polish vapours which may last for a number of hours.
• In case of breakdown or other failure, switch off the radiator at both wall switches and contact your supplier or Dimplex Customer
Services. Always ensure that the radiator is switched off at the wall and fuse is removed before any repair is carried out.
• IMPORTANT - Due to the newness of the materials the radiator will produce a slight smell for the first few days of operation.
ROOMS MUST BE WELL VENTILATED AND YOUNG CHILDREN, CAGED BIRDS OR PERSONS WITH RESPIRATORY
COMPLAINTS MUST NOT REMAIN IN CLOSE PROXIMITY TO THE RADIATOR DURING THE FIRST 48 HOURS OF
THE COMMISSIONING PERIOD. Running the radiator at maximum temperature for the first few days will help to dispel
any smells more quickly.

Your DuoHeat radiator works by providing continual warmth from a carefully balanced combination of “retained” and “radiant” heating. Some
energy is taken in by the radiator when electricity tariffs are low and this is supplemented whenever needed by top up heat from a radiant front
panel, to ensure room temperatures remain to your preferred level throughout the day.
In order for the radiator to operate effectively both electricity supplies must
be left switched ON at ALL times.
Controls
DuoHeat has two output modes Comfort (Radiant Heat) and
Background (Retained Heat). Each needs to be set to the
correct level to provide the optimum level of comfort.
For DuoHeat to operate correctly, both electricity
supplies must be switched on at all times.
Initial Set Up
When the radiator is switched on red lights will illuminate on the
temperature control display located on the top right hand side of
the radiator. The radiator will automatically be in Comfort mode.
Depending on your comfort requirements, there are three
recommended settings:-
“Low” (e.g. holiday home during period of vacancy)
“Normal “ (e.g. average use)
“High” (e.g. sheltered accommodation)
Both the Comfort and Background heat settings need to be set
accordingly.
Please note that at high setting the room temperature will be
warmer with a corresponding increase in running costs.
“Normal” Setting
This is the factory default setting, however you should check this
has not been altered by the installer.
“Low” Setting
Reduce the Background setting to 1 bar.
Reduce the Comfort control to 1 bar.
“High” Setting
Increase the Background setting to between 7 bars.
Increase the Comfort control to between 7.
Operate the radiator for 24 hours before making further
adjustments to the settings.
Achieving Optimum Comfort Level
If the room is not at the desired temperature in the afternoon /
evening, adjust the Comfort Heat simply by pressing the + or
button to achieve a higher or lower room temperature.

It may require a few days fine-tuning to achieve an optimum
comfort level. On subsequent days increase or decrease
the temperature by one red light until a satisfactory comfort
level has been established. Once established the radiator
will automatically adjust to suit seasonal changes in
temperature. During mild weather background heat may not
operate as Comfort Heat will be sufficient.

Everyday Operation
Once the Background level has been set (see Achieving
Optimum Comfort Level above), this should not require any
further adjustment.
Adjust the Comfort setting as required to suit your comfort needs
and occupancy pattern. For a short period of non occupancy
the control can be lowered slightly (we recommend by no more
than 2 bars) to save energy when the room is unoccupied and
increased again when more heat is needed.
Non Occupancy (vacant)
For long periods of non occupancy, reduce the Background
and the Comfort to their lowest settings.
It will take 24 hours for room temperature to reach a
comfortable level when resetting from Low settings to
Normal settings.
Child Lock Operation
To activate the child lock simultaneously depress the
buttons for a period of 3 seconds. After this period the child lock
is in operation and the LED will illuminate for short period and
then revert to the setback setting. The LED beside the key symbol
will illuminate while the child lock is in operation.
Once in the locked position, if either of the controls are operated
the LED will resume maximum illumination for a short period before
reverting back to the setback position.
To deactivate the child lock, depress the buttons simultaneously
again for 3 seconds and the buttons will become active.

Safety - Overheat Protection
For your safety, this appliance is fitted with thermal cut-outs. In
the event that the product overheats, the cut-outs switch the
radiator off automatically. In the event of these safety cut-outs
activating please inform the installer or Dimplex Customer Services
for advice in order to reset the cut-outs.

Cleaning
To maintain the external appearance of the radiator it need only be wiped over occasionally with a dry duster. During the summer months,
or at other times when the appliance is not is use and is completely cold, the opportunity should be taken to wipe over with a damp cloth.
Do not use abrasive cleaning powders or furniture polish.
Discoloration of wall finishes can sometimes occur immediately above a radiator due to the properties of some paints and decorating
materials or the presence of environmental impurities in the air (such as soot or incense generated from the burning of candles etc.).
