Important Safety Advice
When using electrical appliances, basic precautions
should always be followed to reduce the risk of fire,
electrical shock, and injury to persons, including the
following:
IIMPORTANT – The wall brackets supplied with the
appliance must be used.
IMPORTANT – If the heater is installed in a room
containing a bath or shower, it must be so installed that
switches and other controls cannot be touched by a
person using a bath or shower.
Do not use outdoors.
Do not locate the heater immediately below a fixed socket
outlet or connection box.
Do not cover the heater. Do not place material or
garments on the heater, or obstruct the air circulation
around the heater, for instance by curtains or furniture,
as this could cause overheating and a fire risk.
NEVER cover or obstruct in any way the heat outlet slots
at the top of the heater or the air inlet slots in the base of
the heater.
The heater carries the Warning symbol indicating
that it must not be covered.
WARNING – THE SURFACES OF THIS HEATER CAN BE HOT.
Momentary contact with any part of the heater should
not cause injury. However, aged or infirm persons or
young children should not be left unsupervised in the
vicinity of the heater unless a suitable guard is fitted.
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.
Note that due care and consideration must be taken
when using this heater in series with a thermal control,
a program controller, a timer or any other device that
switches on the heat automatically, since a fire risk
exists when the heater is accidentally covered or
displaced.
If the supply cord is damaged it must be replaced by the
manufacturer or service agent or a similarly qualified
person in order to avoid a hazard.

Electrical
WARNING – THIS APPLIANCE MUST BE EARTHED
The electrical installation must be carried out by a competent
electrician, and be in strict accordance with the current I.E.E.
regulations for Electrical Equipment in Buildings.
The wires in this mains lead are coloured in accordance
with the following code :
GREEN AND YELLOW : EARTH
BLUE : NEUTRAL
BROWN : LIVE
BLACK : PILOT WIRE
- see also ‘Pilot Wire Connection’.
The heater is fitted with a length of flexible cable type H05VV-
F size 4 x 1.0mm2for connection to the fixed wiring of the
premises through a suitable connection box positioned
adjacent to the heater.
The supply circuit to the heater must incorporate a double
pole isolating switch having a contact separation of at least
3mm.
Pilot Wire Connection
The BLACK control wire is designed to carry a signal from
slot in or wall mounted Dimplex programmers. If, however a
programmer is not being used, the pilot wire should be
isolated in accordance with the current IEE Wiring
Regulations.
IMPORTANT - DO NOT connect the BLACK pilot wire to earth.
Care should be taken with the installation of the pilot wire(s)
as when switching to background (set back) they become
energised at 240V although only at a current of less than
100mA. In every case a suitable means of isolation must be
provided for the pilot wire and marked to indicate that two
sources of supply may be present at the heater.
Where pilot wires are installed separately from the heater
final sub-circuit they should be protected, double insulated
and carry their own integral earth continuity conductor.
Supplementary Earth Bonding
Should Equipotential Earth Bonding be required the earthing
conductor in the supply cord is deemed to provide the
supplementary bonding connection (see Regulation 547-
03-05, 16th Edition I.E.E. Wiring Regulations).

General
The EPX Convector is designed for wall mounting on the
wall brackets supplied. It should only be operated when in
the upright position as shown.
All models are splashproof to IP24 standard.
Before connecting the heater check that the supply voltage is
the same as that stated on the heater.
Wall Mounting
IMPORTANT – The wall brackets supplied with the appliance
must be used. The heater should be positioned observing
the minimum clearances stated around the heater - see
Fig. 1.

heater by depressing the spring latch at the top of
each bracket - see Fig. 2.
2. Fix the wall bracket securely to the wall through the
four screw holes provided.
3. Present the heater to the wall bracket, and engage
lower slots in the back with bracket.
4. Raise the heater to upright position and push the
heater onto brackets to engage top latch.
Operation
Switching On the Heater (see Fig. 3)
The button marked ‘ ’ controls the electricity supply to the
electronic thermostat. An indicator beside the ‘ ’ button
shows when the unit is powered ‘ON’.
Setting Desired Temperature (see Fig. 3)
The heater is fitted with an adjustable thermostat enabling
the room temperature to be controlled by adjusting the slider
accordingly. The min setting ‘ ’ represents a room
temperature of approximately 50C and may be used for
protection against frost. The ‘MAX’ setting represents a room
temperature of approximately 300C. The ‘ ’ symbol glows
when the elements are actually heating.

Turn on the heater using the ‘ ’ button and move the
thermostat slider to the desired position. When the room
temperature has reached the desired level, the power to the
elements will be reduced, the heater will then maintain the
room temperature at the chosen level.
NOTE - Should your heater fail to come on when the
thermostat slider is at a low setting, this may be due to the
room temperature being higher than the thermostat setting.
Background Temperature
When used in conjunction with a remote programming device
supporting a background/setback setting, the heater will
automatically operate at a room temperature setting of 50C
less than the thermostat setting when the programme is in
background/setback mode.
Limiting the thermostat setting
Before wall mounting the product the installer may wish to
limit the heat selection slider movement for the operator.
This may be achieved by removing the two plastic pins (see
‘x’ in Fig. 4) from the rear of the thermostat moulding using
pliers and inserting them in the preferred holes to limit the
slider movement.
Notes to the Installer
Test Mode
When the EPX Panel Heater is connected via a pilot wire
system, the test mode allows the installer to check whether
the heater is responding correctly to the incoming pilot wire
signal.
Before switching the heater on at the mains, place the
thermostat slider in the ‘MAX’ position, then press and hold
the ‘ ’ button whilst switching on the mains.
The unit will now enter a test state for 4 mins. During this test
state the ‘ ’ neon will indicate the pilot wire status:

Energy Saving Tips
The energy we use to heat, light and power our homes
contributes over a quarter of the UK’s carbon emissions, the
principle contributor to climate change.
Around half the energy used in the home is for heating and
hot water, so using your heating system efficiently will not
only help the environment, but also save you money!
Energy efficiency tips for heating and hot water
1. Don’t set the temperature too high…
By reducing the thermostat setting by just 1ºC can reduce
your energy use by as much as 10%. And if you’re going
away for the winter, leave the thermostat on the frost protection
setting to provide protection from freezing at a minimum cost.
2. Use it where you need it…
Set the appropriate temperature on your heaters for the room
they are in; for example, leave the thermostat on a heater in a
spare bedroom on a lower setting.
3. Use it when you need it…
Use heaters fitted with timers or linked to central controllers
to turn the heating on only when you need it and automatically
switch it off when you don’t.
4. Curtains…
Close your curtains at dusk to stop heat escaping through
the windows.
5. Windows…
Nearly 25% of heat loss can occur through poorly insulated
frames and single glazing. If you can’t afford to double glaze
all your windows, go for the rooms you heat most.
6. Treat your hot water tank...give it a jacket
An insulating jacket for hot water tanks only costs a few pounds
and pays for itself within months. Fit one that’s at least 75mm
(3") thick and you could save £10-£15 a year.
7. Water …
Use a shower if you have one to save time, money and water.
Don’t set the thermostat too high on your water heater - 60oC/
140oF is usually adequate for bathing and washing.
Put the plug in when running hot water in your sink - leaving
hot taps running is both wasteful and expensive.
Ensure dripping taps are repaired quickly. In just one day,
you could waste enough water to fill a bath
Other Energy Saving Tips for Around the Home
1. Lights
Turn off lights whenever you leave a room for more than ten
minutes.
Use low-energy bulbs wherever you can as they use less
than a quarter of the electricity used by ordinary light bulbs
and last ten times longer!
2. Cooking
Use the right size pan for the food and cooker hob.
Keep saucepan lids on - this enables you to turn down the
heat.
Boil water for cooking in a kettle.
