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.

THESE INSTRUCTIONS SHOULD BE READ CAREFULLY AND RETAINED FOR FUTURE REFERENCE
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.
Set the Background setting at the mid point (5th bar). To do this, press the +button until 10 bars are illuminated and continue to hold for a further 7 seconds. Adjust by pressing the + or - buttons.

“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.
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 10 red lights are illuminated, continue to hold the +button for a further 7 seconds and a single red light will flash. Use the +button to increase room temperature and the flashing red light will move to the right. Use the -button to decrease room temperature and the flashing red light will move to the left.
Flashing Bar
After 20 seconds the temperature control will display will return to the Comfort Heat control mode.
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.
