Operating Instructions
IMPORTANT SAFETY INFORMATION
WARNING - THE SURFACE OF THIS RADIATOR CAN BE HOT.
The surface temperatures of this radiator are within the requirements of EN60335 the European Standard covering the safety requirements of electric
heating appliances.
If aged or infi rm 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 fi tted around the radiator. If you require further information
please contact Dimplex Customer Services on 0845 600 5111.
This appliance is not intended for use by persons (including children, who should be supervised) with reduced physical, sensory or mental capabilities,
unless supervision or instruction has been given concerning use of the appliance by a person responsible for their safety.
• 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, e.g., 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
• Radiator Positioning A minimum clearance of 150mm to the front of the radiator is essential for safety, however to enable the radiator to attain its
maximum performance ensure that any furniture or other obstruction is not placed closer than 250mm.
• 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 fi rst seeking specialist advice. UNDER NO CIRCUMSTANCES SHOULD THE RADIATOR BE MOVED OR WALL FIXINGS
LOOSENED WITHOUT FIRST REMOVING ALL ENERGY RETENTION CELLS FROM THE RADIATOR.
• Ensure the radiator is at least 75mm from any end wall or curtain and at least 250mm below any shelf or similar projection
• 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 paraffi n 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 fi rst 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 fi rst 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.
Everyday Operation
Once the Background level has been set to your preferred level (see
‘Controls’ overleaf), 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 comfort
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 Frost Protection Setting.
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 + and
-
buttons
for a period of 3 seconds. After this the child lock is in operation and the
LED display will illuminate for short period, before reverting back to a
dimmed setting. The red LED beside the lock symbol will illuminate to
indicate that the controls are locked.
Once in the locked setting, pressing the + or - button will no longer
affect your settings. If either of these buttons are depressed, the LED
display will resume maximum illumination for a short period before reverting
back to a dimmed setting.
To deactivate the child lock, depress the + and - buttons simultaneously
again for 3 seconds. The red LED beside the lock symbol should go out
and the buttons will become active.
Safety - Overheat Protection
For your safety, this appliance is fi tted 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.

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.
Set the Background setting at the 4th red LED bar. To do this,
press the
+
button until all red bars are illuminated, and continue
to hold for a further 10 seconds. A single red bar will fl ash to
indicate that you are now viewing the backgound setting. Adjust
this bar by pressing the + or -buttons.
After 10 seconds, the display will revert to the standard Comfort
mode.
Set the Comfort at the 4th red LED bar by pressing the
+
or
-
buttons to change the number of illuminated bars.
“Low” Setting
Reduce the Background setting to
Frost Protection Setting (Blue LED).
Reduce the Comfort control to Frost
Protection Setting (Blue LED).
“High” Setting
Increase the Background setting to the 7th red LED bar.
Increase the Comfort control to the 7th red LED bar.

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.
If the morning room temperature is not at the desired level, then
adjust the Background heat level by pressing and holding down
the
+
button on the temperature control display until all red lights
are illuminated, continue to hold the
+
button for a further 10
seconds and a single red light will fl ash. A single red bar will fl ash
to indicate that you are now viewing the backgound setting. Use
the
+

light will move to the right. Use the
-
button to decrease room
temperature and the fl ashing red light will move to the left.
After 10 seconds the temperature control display will return to the
Comfort Heat control mode.
It may require a few days fi ne-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 suffi cient.

Cleaning - WARNING – ALWAYS DISCONNECT FROM THE POWER SUPPLY BEFORE CLEANING THE RADIATOR.
To maintain the external appearance of the radiator it need only be wiped over occasionally with a dry duster. Allow the radiator to cool, then wipe with
a dry cloth to remove dust and a damp cloth (not wet) to clean off stains. Be careful not to allow moisture into the radiator. Do not use abrasive cleaning
powders or furniture polish.
Discoloration of wall fi nishes 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.).
