Electrical connection

WARNING – THIS APPLIANCE MUST BE EARTHED

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 fitted 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 fitted 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

THESE INSTRUCTIONS SHOULD BE READ CAREFULLY AND RETAINED FOR FUTURE REFERENCE.

Wall Mounting

Three identical wall mounting brackets are secured to the base of the
heater with a fixing screw. To wall mount appliance, first remove the
brackets as follows :
Lay the heater on its back.
Following the sequence in Fig. 1 – identify and remove the fixing screw
securing the brackets located beside Mains Cable as shown in (a), then
pull out brackets and rotate them to disengage them from the slot (b).
Withdraw the brackets from the slot (c).

(a) (b) (c)

Fig. 1

Select a suitable position on a wall, near to a mains power socket,
making sure that there is at least 230 mm below the heater and at least
450 mm above the heater of unobstructed space. See also ‘Positioning
the heater’.
Fix the two top retaining brackets to the wall, using suitable fixings, for
2kw models at 358 mm centres and 3kw models at 478 mm centres –
see Fig 2.

Fig. 2

Locate the heater on the top brackets and allow it to hang in place.
Fit the bottom bracket into the slot in the heater and then fix it to the wall.

Test that the heater is now securely fixed to the wall.

Positioning the heater

Always ensure that the heater is stood on a firm, 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 fire hazard.
We recommend that the heater should be wall-mounted in rooms where
children may be left unattended.
See also ‘Important Safety Advice’.

Free standing use

NEVER USE THE HEATER FREE STANDING WITHOUT THE FEET
FITTED.

Lay the heater on its back,
and locate the foot fixing
screw (see a. in Fig. 3).
Remove the screw using
an X–head screwdriver,
then align foot over slots
and holes in base (see ‘b’
in Fig. 3) and push into
slots until the foot clips
into place.
Finally take the foot fixing
screw, insert and tighten
using a screwdriver to
secure the foot.

Fig. 3

NOTE – The wall mounting brackets indicated in Fig. 3 can be left secured
to the base if they are not required.

Using the heater

Plug in and switch on at the wall socket.
On models 3082S & 3087S the timer clock will operate all the time that

the heater is connected to the mains supply, regardless of the setting of
the heat selector switch. Set the timer control switch as required for OFF,
Manual or Automatic
operation – see ‘Timer Operation’.

The heat output is controlled by the
thermostat - see ‘Thermostat’

Please note – the element has been
coated with a protective film which will
burn off during the first 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 first time.

Controls

Thermostat

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, turn the thermostat knob clockwise
until the desired temperature is reached. Alternatively to heat a cold room
quickly, turn the thermostat knob up fully.
When the room has reached the desired temperature, turn the thermostat
knob anti-clockwise until the thermostat just clicks off.
The heater will now automatically operate at this 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.

Heat Selector Switch

Heat selection is available on all models as an economy feature.
On models 3082S and 3087S - the switch is a 2 position switch with two

possible heat settings as follows :
I - The heater operates at half heat output.

II - The heater operates at full heat output.
On models 3088T and 3088TA - the switch is a 4 position switch with an

Off position marked ‘O’ and 3 possible heat settings as follows :;
I - The heater operates with 1kW output

II - The heater operates with 2kW output
III - The heater operates with full 3kW output

ON/OFF Switch

On model 3087ST – the switch operates as follows :
O - The heater is off

I - The heater operates with 2kW output

Note : The above description of the On/Off switch operation is with the
turbo neon switch in the off position – see also ‘Model 3087ST’ in the
‘Turbo Fan Models ..’ section.

Digital Timer Operation

IMPORTANT Remember to observe all safety warnings when operating

the heater on auto setting unattended or attended .

The timer allows you to select ‘MANUAL ON’ , ‘AUTO’ or’ MANUAL
OFF’ operation mode by pressing the ‘MODE’ (Input/Output) button until
the required mode appears at the bottom of the timer display.

‘MANUAL ON’ mode allows power to the heater uninterrupted by the
timer settings. The heat selector switch will control the output (see ‘Using
the heater’).
‘AUTO’ mode allows the convector to switch ON and OFF according to
the timer settings (see ‘Setting Programs’ section below).

‘MANUAL OFF’ mode switches off all heater operation completely.

12/24 Hour Mode Either 12 or 24 hour modes can be used.

Press the S (Set) and PROG (Program) buttons simultaneously to switch
between 12 and 24 Hour mode.

Initial Operation

For initial use, plug the heater into a regular household power point and
turn the power on.
The ‘Power On’ neon will only light, when the heater is connected to the
power supply and the timer is in either ‘MANUAL ON’ or ‘AUTO’ On
mode.
Clear all current information by pressing the R button with a pointed
object such as a pencil. Note: Do not use a needle or pin.
The timer is now ready to be set up for use.
