Dimplex CXD Ceramic Radiant Heaters
Model(s) : CXD2000H & CXD2000V
Important Safety Advice
Because the Dimplex Ceramic Radiant Heater contains
no moving parts little maintenance is required. Before
undertaking any maintenance work on the heater due
attention must be paid to the following:
This heater is designed to be horizontally wall mounted
only, it must not be ceiling mounted.
Always ensure a safe mounting height, at or above a
minimum height of 1.8 metres from ground level, so
that the heater can not be touched when in operation.
The heater must be wall mounted level ± 5º to the
horizontal.
Do not locate the heater immediately above or below a
fixed socket outlet or connection box.
This appliance is not intended for use by children or
other persons without assistance or supervision if their
physical, sensory or mental capabilities prevent them
from using it safely. Children should be supervised to
ensure that they do not play with the appliance.
Always disconnect the heater from the electricity supply
before attempting to work on or near it.
Always ensure a safe means of access using an access
tower or properly supported ladder.
Do not cover the heater.
Keep combustible materials away from the heater.
Do not position patio furniture, sunshades, awnings and
other combustible materials too close to the heater.
Do not use heater if the elements are broken - as injury
may occur.
Allow adequate time (minimum of 30 mins.) for the
elements and body casing to cool before attempting to
work on the heater .
Wiring between the heater and the spur outlet or
isolation switch must be in a heat resisting cable (e.g.
polychloroprene).
Note: Provide sufficient slack to the cable to allow for
angular adjustment of the body.
The supply cord should be regularly examined for signs
of damage and the appliance is not to be used if the
cord is damaged.
General
Your Dimplex Ceramic Radiant Heater uses ceramic
elements which produce a high proportion of their output in
the long-wave infra-red. This provides a high comfort factor
– similar to the natural energy from the sun.
Electrical
The installation of this appliance should be carried out by a
competent electrician and be in accordance with the
current IEE wiring regulations and any local or insurance
regulations.
The CXD2000H & CXD2000V are designed for use on a
230-240V AC single phase supply.
An all-pole isolating switch with a minimum separation of
3mm in each pole must be fitted to facilitate isolation. This
switch must either be positioned inside a building or have
an IP rating against water ingress suitable for external
installation.
THESE INSTRUCTIONS SHOULD BE READ CAREFULLY AND RETAINED FOR FUTURE REFERENCE
The appliance must be supplied through a residual current
device (RCD) having a rated residual operating current not
exceeding 30mA.
The appliance must be connected to a socket-outlet having
an earthing contact.
We recommend that a cable with a minimum specification of
H07RN-F polychloroprene sheathed or similar be used with
a minimum temperature rating of 90°C.
Note :
Always ensure the cable grip is tightened.
Installation
Heaters are supplied with an integral wall bracket which may
be fixed through the mounting holes to any suitable structure.
The bracket allows the heater to be inclined at the required
angle. The recommended fixing height to the centre line of
the bracket is 2.0m from ground level - see
Fig. 2
.
The integral wall fixing bracket may be removed by fully
unscrewing to facilitate its fixing.
The siting of the heater(s) should be such as to allow an
even and uninterrupted distribution of radiation to the area(s)
to be heated. Heaters are most effective when the beam
angle is inclined down at an angle of between 30º to 45º to
the vertical - se

Fig. 2
.
When deciding upon the best location, consideration must
be given to the following requirements:
a
. Avoid structures which might vibrate e.g. crane gantries.
These could adversely affect element life.
b.
Comfort and safety could be compromised unless the
heater is mounted at or above 1.8m from ground level.
c
. Allow a minimum of 500mm minimum clearance
between the top of the heater and any horizontal surface
- see
Fig. 1
.
Element Replacement
(see
Fig. 4
)
WARNING – BEFORE UNDERTAKING THIS TASK ENSURE THE
HEATER IS DISCONNECTED FROM THE ELECRICITY SUPPLY
AND LEFT TO COOL FOR A MINIMUM OF 30 MINUTES.
1. The heater should be taken off the wall.
2. Remove the screws (a) and (b) which hold the control
box on the back of the heater.
3. This will allow access to the elements. Remove the
retaining clips and spring clips (c) to loosen the
elements.
4. Disconnect the elements from their terminal blocks.
5. Remove the screws (d) which hold the back panel.
6. Remove the splash brackets (e) on the elements.
7. Bend the bars on the guard as indicated in
Fig. 3
to
remove it.
8. The old element should drop out through the front of the
heater, reverse the process when replacing with the new
element.
