attention has to be given where children and
vulnerable people are present.
If the mains lead is damaged, it must be replaced
by the manufacturer or its service agent or a
similarly qualied 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
wall socket.
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
efcient 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 conrm 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.

The appliance has a frost protection mode. This setting is useful in areas
such as garages to assist in the prevention of frost damage. In Manual
mode, if the thermostat is set to its minimum setting ‘5°C’, the heater will
cycle ON and OFF to maintain a temperature of approximately 5°C and
help protect against frosty conditions. The frost protection symbol will
be displayed on the LCD display when frost protection mode is activated.
Indicator Neons
Mains On Neon: The mains neon, (see Fig. 5), remains illuminated when
the power is supplied to the product. Note: This does not indicate whether
the heating elements are on.
Heat Neon: Heat neon remains on when the heating element is active.
Once the desired temperature is reached and the element turns off, the
heat neon will indicate this by remaining off.
Bluetooth Neon: The Bluetooth neon will remain illuminated while
successfully paired to another device.
Setting the Desired Temperature
The desired temperature can be set using the ‘ ’ or ‘ ’ keys. The
temperature can be set from 5˚C to 30˚C and this will be shown on the
display. When the temperature is reached the heater will automatically
switch OFF. If the ambient temperature drops the heater will come on
again automatically.
Setting the Timer Programmes
There are four program segments available, P1, P2, P3 and P4. For each
segment it is possible to set a desired ‘On’ time, ‘Off’ time, Heat mode
and set temperature. It is not necessary to set all four segments if not
required. The default setting is for all segments to be Off. To turn off a pre-
programmed segment it is necessary to set both the ‘On’ time and the ‘Off’
time to 00:00. In order to set up a time/temperature prole the following
steps must be completed:
1. To activate the programming screen press the ‘ ’ key. The program
settings screen for P1 will be displayed and the time will be ashing. This
ashing time is the ‘On’ time for P1 and can be adjusted using arrow keys.

using the ENTER key.
4. The ‘Off’ time must then be set by using the arrow keys, it is necessary
to then press the ENTER key to conrm the ‘Off’ time setting.
5. The setup screen will then revert to the P1 ‘On’ time set up screen, at
this point it is possible move to the P2 segment by pressing the ‘ ’ key.
6. If required P2, P3 and P4 segment can be set up using steps 1-4 above.
7. If it is not required to set up P2, P3 and P4 segment at this stage, continue
to press the ‘ ’ key until the heater reverts to the previous operational mode.
Alternatively if no keys are pressed the programming mode will time out
and revert to the previous operational mode.

Safety – overheat protection
For your safety, this appliance is tted with a thermal cut-out. In the event
that the product overheats, the cut-out switches the heater off automatically.
To bring the heater back into operation, remove the cause of the overheating,
then unplug or turn off the electrical supply to the heater for a few minutes.
When the heater has cooled sufciently, re-connect and switch on the
heater.

Important Notes
Although this heater is manufactured to comply with the relevant safety
standards, certain types of carpets could become discoloured by the
temperatures under a portable heater. If you are concerned about this,
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 airow 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.
