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 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
wall socket.
There are various control options available with various combinations
comprising of thermostat, switched, timer & indicating neons.
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’.

Fig. 1
Thermostat (all models)
The thermostat controls the heat output according to the room temperature.
This ensures that the heater will not produce heat unnecessarily when the
room is warm.
To set the temperature you require, gradually turn the thermostat knob
clockwise until the desired temperature is reached. Allow some time
between increments for the room temperature to stabilise.
Alternatively to heat a cold room quickly, turn the thermostat knob to the
Max position. When the room has reached the desired temperature, turn
the thermostat knob anti-clockwise until the thermostat clicks off. The heater
will then automatically maintain this room temperature.
The thermostat also has a frost protection setting marked ‘ ’. This setting is
useful in areas such as garages to prevent frost damage. If the thermostat is
set to its minimum setting ‘ ’, the heater will cycle ON and OFF to maintain
a temperature of approximately 5°C to help protect against frosty conditions.
Switches (selected models)
Some models are supplied with selector switches . There are two switch
types, one is an on/off switch and the other is a heat selection switch.
Depending on model either one or both switch may be included. The switch
operation is as follows.
On/ Off: O - Off
I - On
Heat selection I - Low heat
II - High heat
403TS Operation
This model contains an On/Off switch and a heat selection switch and
operates as follows.
When O/I switch is in position O the product is off regardless of any
other setting. When O/I switch is in position I and the I/II switch is in the
I position there is a 2kw output from the product. When O/I switch is
in position I and the I/II switch is in the II position there is a 3kW output
from the product. The indicator neon is always on when the product is
connected to the mains supply.
403TSTi Operation
This model contains a heat selection switch and an electro-mechanical
timer and operates as follows.
When the timer is switched to I and the I/II switch is in position I there is
a 2kW output from the product. When the timer is switched to I and the
I/II switch is in position II there is a 3kW output from the product. When
the timer is in the ‘ ’ position and the I/II switch is in position I there is a
2kW output from the product when the timer is set on. When the timer is
in the ‘ ’ position and the I/II switch is in position II there is a 3kW output
from the product when the timer is set on. The indicator neon is always
on when the product is connected to the mains supply.

Setting the time of day
To set the time of day, rotate the timer dial clockwise (indicated by the arrow)
until the correct time of day is opposite the reference mark
(see Fig.
6). The 24-hour clock is used ; e.g. time shown for 3 pm is ‘15’ (15:00hrs).
Setting the ‘Auto’ ON and OFF times
To set the timer :
1. Using your nger tip or the tip of a
pencil, push in as many segments as
necessary around the dial, according
to the times you don’t require heat –
see Fig. 8. Each segment pushed in
switches the heater OFF for that part of
the hour. All other segments will be ON.
For example, Fig. 9 shows the timer
set to switch the heater ON between
9.00am and 4.00pm and between
9.30pm and 7.00am.
2. You can select as many ON periods as you like, within the 24-hour day.
The settings will repeat every day until changed.
3. To change ON and OFF times, simply push in any ‘ON’ segments you
wish to cancel and pull out new ‘ON’ segments as required.

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 sufciently, 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 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.
