Thank you for choosing this De’Longhi radiator. To get
the very best out of your new radiator it is advisable to
read these instructions before using it.This will ensure
that you gain optimum results and use the appliance
safely.
General instructions
Take the radiator out of its packing box and remove any
polstyrene pieces or any other packaging material that might
be lodged inside it. Make sure that the radiator has not been
damaged during transit and that the mains cable is in working
order. Do not operate the radiator if damaged.
“Easy wheel”system
Turn the radiator upside-down on a rug or a soft surface in
order to prevent damaging the paint finish. Fully unfold the
castors by turning them outwards (Fig. 1). Turn the radiator
back to its upright position.
Using for the first time
On using the radiator for the first time we advise that you turn
it on to the maximum power setting for at least 8 hours.
This is to eliminate the “new odour”, which is released by the
appliance. During this time ensure that the room is well
ventilated.
Electrical connection
- Before plugging the radiator into the mains, check that your
supply voltage is the same as that shown on the rating plate
of the appliance.
- If using more than one radiator at a time, it is important to
ensure that the ring main is adequate to cope with the
power requirements.
- It is important to ensure that the socket is adequately earthed.
- This radiator complies with EEC Directive 89/336 relating to
electromagnetic compatibility.

increase or decrease the temperature by 1°C. Keep either button
pressed down to move through the temperature quickly.
Electronic Climate Control
This heater has Electronic Climate Control which automatically
monitors and selects the ideal power setting to maintain your
chosen temperature. If the selected temperature is higher than
the actual room temperature, the appliance will start
automatically and rapidly heat the room until it reaches the
selected temperature. If maximum power has been selected the
unit will automatically maintain the temperature at a constant
level, by switching between maximum, medium, minimum power
and stand-by position (If the room temperature exceeds the
selected temperature level the radiator will switch in stand-by).
If medium power level has been selected using the “ON
MODE” button, the appliance will modulate between medium,
minimum power and stand-by position to maintain a selected
temperature.
Note: the display will always show the power setting
you have chosen, not the one it is currently working at.

Electrical requirements
Before using this appliance ensure that the voltage indicated
on the product corresponds with the main voltage in your
home, if you are in any doubt about your supply contact your
local electricity company.
The flexible mains lead is supplied connected to a B.S. 1363 fused plug
having a fuse of 13 amp capacity. Should this plug not fit the socket
outlets in your home, it should be cut off and replaced with a suitable
plug, following the procedure outlined below. Note: Such a plug
cannot be used for any other appliance and should therefore be
properly disposed of and not left where children might find it and plug
it into a supply socket - with the obvious consequent danger. N.B. We
recommend the use of good quality plugs and wall sockets that can be
switched off when the machine is not in use. important: the wires in the
mains lead fitted to this appliance are coloured in accordance with the
following code:
As the colours of the wires in the mains lead of this appliance may not
correspond with the coloured markings identifying the terminals in
your plug, proceed as follows:
The wire which is coloured green and yellow must be connected to the
terminal in the plug which is marked with the letter E or by the earth
symbol or coloured green or green and yellow.The wire which is
coloured blue must be connected to the terminal which is marked with
the letter N or coloured black.The wire which is coloured brown must
be connected to the terminal which is marked with the letter L or
coloured red.When wiring the plug, ensure that all strands of wire are
securely retained in each terminal. Do not forget to tighten the mains
lead clamp on the plug. If your electricity supply point has only two pin
socket outlets, or if you are in doubt, consult a qualified electrician.
Should the mains lead ever require replacement, it is essential that this
operation be carried out by a qualified electrician and should only be
replaced with a flexible cord of the same size. After replacement of a
fuse in the plug, the fuse cover must be refitted. If the fuse cover is lost,
the plug must not be used until a replacement cover is obtained.The
colour of the correct replacement fuse cover is that of the coloured
insert in the base of the fuse recess or elsewhere on the plug.Always
state this colour when ordering a replacement fuse cover. Only 13amp
replacement fuses which are asta approved to B.S. 1362 should be
fitted.This appliance conforms to the Norms EN 55014 regarding the
suppression of radio interference.
