IMPORTANT
WARNING - THE SURFACE OF THIS HEATER CAN
BE HOT.
WARNING - THIS APPLIANCE MUST BE EARTHED.
• The installation must be carried out by a suitably qualified
individual in accordance with the latest IEE Regulations for
electrical equipment.
• 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
that it has been placed or installed in its intended normal
operating position and they have been given supervision or
instruction concerning use of the appliance in a safe way and
understand the hazards involved. Children aged from 3 years
and less than 8 years must not plug in, regulate and clean the
appliance or perform user maintenance.
CAUTION — Some parts of this product can become very
hot and cause burns. Particular attention has to be given
where children and vulnerable people are present.
• If aged or infirm persons, or young children, are likely to be left
unsupervised in the vicinity of a heater precautions should be
taken to ensure that prolonged contact with the heater cannot
occur.

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.

Preparation
1. Place the heater flat on the ground with arrows
printed on the base of the carton pointing upwards.

of the carton by at least 200mm exposing the feet
and the fixing kit located within the packaging on
the right hand side. Remove the feet and the fixing
kit.
2. Secure the feet to the heater. For models
QM050, QM070 and QM100 two locations are
possible indicated by Xand Ymarkings visible on
the base of the heater.
Ensure the feet are !xed at the location holes
marked with an ‘X’, see Fig. 2.
However, if this is a replacement heater check the
pitch of the feet and choose the appropiate fixing
positions - either X or Y.
Note - Foot screws are in the !xing kit.
Stand the heater on its feet before removing the
packaging.

Installing the Heater
The heater must be securely fixed to a wall. Screws
with suitable wall fixings for solid walls are provided.
If other wall types are encountered it is the installer
who must choose the most suitable fixing.
SUGGESTED FIXINGS
SOLID BRICK/BLOCK: No. 10 size high
temperature resistant plastic inserts, 8mm drill bit.
Drill hole 15mm deeper than plastic insert length.
PLASTERBOARD - If possible locate studding and
use No. 10 woodscrews directly into the wood,
otherwise M5 rawlplug intersets are suitable.
NOTE: FOR OTHER WALL TYPES (eg. timber
frame and hollow concrete) SEEK SPECIALIST
ADVICE.
If the floor is carpeted then the carpet should be slit
and underlay cut away to allow the feet to rest firmly
on the floor. Carpet gripper must be locally removed
so that the feet may rest in a level position.
This appliance is heavy. The floor must be checked
to ensure that it is capable of bearing the weight of
the unit, up to 165kg.
DO NOT UNDER ANY CIRCUMSTANCES
ATTEMPT TO MOVE OR REPOSITION THIS
HEATER WITHOUT SEEKING EXPERT ADVICE.

6. Place the heater in its final position and mark
the fixing holes through the location holes visible
through the back of the heater.
Mark the fixing positions at the two extreme ends of the
heater with the heater pushed tight against the wall.
Remove the wall bracket from the heater by removing
the two screws at each end of the bracket. Place
the heater to one side and reposition the bracket
against the wall aligning it with the location marks. It is
advisable to use a screwdriver with a magnetic tip
as screws dropped may enter the fan housing.
7. Six fixing positions must be selected for each
model. Mark the positions for the fixing holes.
Remove the bracket from the wall, drill the holes
and fit the wall fixings best suited to the application.
Secure the wall bracket to the wall using six screws.
Secure the heater using the appropriate screw fittings.
NOTE: UNDER NO CIRCUMSTANCES SHOULD
ANY SCREWS BE REMOVED WITHOUT FIRST
REMOVING ALL BRICKS FROM THE HEATER.
