• For each supply, a means for disconnection must be incorporated
in the fixed wiring by a double pole switch with a contact
separation of a minimum of 3mm and in accordance with the
current IEE Wiring Regulations.
• The heater must not be installed immediately below a fixed socket
outlet.
• The supply to the storage elements is not suitable for connection
to a 30A ring circuit (24 hour peak supply).
• If a supply cord is damaged, it must be replaced by a qualified
individual in order to avoid a hazard.
The surface temperatures of this heater are within the•
requirements of EN60335-2-61, the European Standard covering
the safety requirements for Electric Storage Heaters, and
momentary contact with any part of the heater should not cause
injury. However, in order to be effective, heaters of any type do
get hot, especially around the air outlet grille.
This appliance can be used by children aged from 8 years and•
above and persons with reduced physical, sensory or mental
capabilities or lack of experience and knowledge if they have
been given supervision or instruction concerning use of the
appliance in a safe way and understand the hazards involved.
Children shall not play with the appliance. Cleaning and•
user maintenance must not be made by children without
supervision.
• Children of less than 3 years should be kept away unless
continuously supervised. Children aged from 3 years and less
than 8 years can only switch on/off the appliance provided

ATTENTION:
IN ORDER TO AVOID
OVERHEATING DO NOT
COVER THE HEATER
Do not place objects within
300mm of the front of the
heater and 150mm (min.
75mm) either side.
Where particularly vulnerable people are likely to be left
unsupervised in the vicinity of the heater we recommend that
a guard is fitted around the heater, as is normal with heating
appliances in similar circumstances. A range of guards
specially designed for Dimplex heaters is available.
If you require further information on these guards, please see
contact details on back page of the Operating Instructions.
CAUTION: DO NOT COVER SURFACES OF THE
HEATER AND DO NOT OBSTRUCT THE AIR
OUTLET GRILLE.
Surfaces of the heater should not be covered or obstructed as•
this can cause excessive temperatures that can be hazardous
and may cause safety cut-outs to operate. This will stop the
heater from working.
Do not put clothes, fabrics or any combustible materials on the•
heater.
• Do not position the heater where objects can come to within
250mm (10”) of the top or 75mm (3”) of the ends of the heater
casing. Do not place objects within 300mm of the front of the
heater.
• Curtains must not come to within 75mm (3”) of the top of the
heater.
• Do not sit or stand on the heater.
Do not place objects in contact with the heater.•
To maintain stability, it is essential that the heater is placed•
on a level surface and care should be taken to avoid irregular
surfaces, such as may result from carpets or tiled surrounds
partially protruding under the heater.
Choose appropriate fixings to securely attach the heater to the wall,•
see section titled ‘Installing the heater’ for detailed information.
This heater must be installed where it is impossible for its•
switches and other controls to be touched by a person using a
bath or shower.
IMPORTANT - Due to the newness of materials the heater will•
produce a 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 heater during the first 48 hours of operation.
PLEASE NOTE: THIS HEATER IS VERY HEAVY AND MUST
BE SECURELY FIXED TO A SOUND WALL.
• If, during any reassembly of the heater, a part of the thermal
insulation shows damaged or deterioration which may impair
safety, it should be replaced with an identical part.
• UNDER NO CIRCUMSTANCES SHOULD THE WALL
FIXINGS BE LOOSENED ON THIS HEATER BEFORE THE
BRICKS HAVE BEEN REMOVED FROM ITS CORE.
• Quantum heaters are not suitable for installation in bathrooms,
shower rooms etc. or in areas of high humidity.
