If the mains lead is damaged, it must be replaced
by the manufacturer or its service agent or a
similarly qualied person in order to avoid a
hazard.
Electrical connection
WARNING – THIS APPLIANCE MUST BE EARTHED
The use of an extension lead or multi-plug adaptor is not advised when
connecting this product to the mains. Connection through these devices
could lead to a risk of overloading, overheating and even re at the extension
lead or adaptor due to inadequate connection quality.
This heater must be used on an ~ supply only and the voltage marked on
the heater must correspond to the supply voltage. This heater is tted with
a rewireable plug incorporating a 13 amp fuse. In the event of replacing
the fuse in the plug supplied, a 13 amp fuse approved by ASTA to BS 1362
must be used. If any other type of plug is used, a 15 amp fuse must be
tted in the plug, the adaptor, or at the distribution board.
IMPORTANT : If the plug is not suitable for your socket, the 13 amp plug
should be removed. Before wiring the appropriate plug, please note that
the wires in this mains lead are coloured in accordance with the following
code : GREEN AND YELLOW: EARTH
BLUE : NEUTRAL
BROWN : LIVE
Connect the GREEN AND YELLOW wire to the terminal marked ‘E’ or
by the earth symbol , or coloured GREEN or GREEN AND YELLOW.
Connect the BROWN wire to the terminal marked ‘L’ or coloured RED.
Connect the BLUE wire to the terminal marked ‘N’ or coloured BLACK.
Using the heater
WARNING: DO NOT USE THE HEATER UNTIL THE FEET OR WALL
BRACKETS ARE FITTED CORRECTLY.
The product can be used as an installed or portable unit. Once the desired
application has been decided upon and the requirements below have been
met the product is ready to be used. Simply plug in and switch on at the

Please note – the element has been coated with a protective lm which
will burn off during the rst few minutes of use and may cause a small
amount of fuming. This is quite normal – the fumes are non-toxic and will
quickly disappear.
We recommend that you open a window to ventilate the room when using
the heater for the rst time.
Positioning the heater
Always ensure that the heater is stood on a rm, level base near to,
but not directly beneath, a suitable mains supply socket.
Ensure that curtains and furniture are not positioned close to the
chosen position, as this would create a potential re hazard.
We recommend that the heater should be wall-mounted in rooms
where children may be left unattended, see ‘Important Safety Advice’.

appliance at any time.
Operational modes
The electronic control has four control modes: AUTO, MANUAL, BOOST
and STANDBY mode.
Auto Mode
Standby ModeBoost Mode
Manual Mode
In both MANUAL and AUTO mode there are three heat settings options:
‘Intelligent’ Eco Mode - This is the initial default setting, the convector will
automatically start up in this setting once power is applied. The convector
will automatically regulate the room temperature accordingly. In this mode
the convector operates at full power, however the output of the convector is
automatically reduced and regulated as the room temperature approaches
the desired level. This mode optimises energy use by calculating the most
efcient and effective way to achieve the desired temperature setting. The
desired room temperature can be adjusted at any time during operation by
pressing the appropriate key.
Low Heat - In this option, the appliance will operate at a low heat setting,
the appliance will automatically cycle at this setting to maintain the room
temperature setting.
High Heat - In this option, the appliance will operate at a high heat setting,
the appliance will automatically cycle at this setting to maintain the room
temperature setting.
Press the Mode key,‘ ’, to toggle through the modes and the ENTER key
to conrm the mode selection. Note: when selecting the mode if the ENTER
key is not pressed, after 5 seconds the heater will activate the mode shown
on the LCD display.

we recommend that you contact the carpet manufacturer for guidance.
Alternatively, either stand the heater on a suitable base to shield the carpet
or wall-mount it – call our Helpline for further advice.
You may notice some parts of the element appearing to be hotter from time
to time because of the variable airow through the heater. This does not
cause a safety hazard.
The heat outlet grille may become discoloured with use – this is caused by
airborne pollution and is not a fault.
