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

Note - Timer Memory Back Up Batteries

Once the heater has been left plugged in with the socket switched on for
at least 12 hours the timers memory back up batteries will be fully
charged.

Once the timer batteries are fully charged , if there is either a power cut
or if the heater is disconnected from the mains for less than 100 hours ,
then the timer will continue to keep time & the settings in the memory will
remain intact .
If however the timer back up batteries have not been charged fully , or if
the heater is deprived of power for longer than 100 hours , then the time
and the programme settings are likely to be lost and you may therefore
need to reset the time and the programme before using in ‘Auto’ mode
again.

Turbo Fan models
(3087ST, 3088T & 3088TA)

The turbo fan can be used to circulate
the heat around the room to help it
reach the desired temperature more
quickly

.

On all turbo models with the heat
selector switch at max. setting (3kw
operation) the fan automatically
switches on to override the operation
of the Turbo On/Off neon switch. This
permanent operation of the fan at
maximum heat setting ensures more
efficient operation and heat circulation
around the room

Model 3088T & 3088TA

On these models you can choose to
use the fan to help circulate the heat

Fig. 6

at lower heat settings by switching the

Turbo Models

Turbo switch on with the heat selection
switch at setting I or II .
In warm weather you can also use the fan on these models to circulate
cool air as follows: Set the heat selector switch to it's off position - 'O' ,
set the Turbo switch to it's on position and set the thermostat to it's
maximum setting by turning the thermostat knob fully clockwise.

Model 3087ST

On this model with the I / II switch at position I and the turbo switch in it’s
Off position ( neon off ) there is no heat output from the convector. With
the I / II switch still in the I position you can have 1kw output but only with
the turbo boost on, also by switching the turbo switch to it’s On position
(neon on). To get an output of 2kW leave the turbo switch off and set the
I / II switch to position II. (Note 2kw is only possible with turbo off). To
achieve 3kw output now turn on the turbo switch which will combine the
2kW setting with a 1kW fan boost setting to give the total output of 3kw
with fan boost.
Note there is no cold blow operation on this model and that all heat
settings operate under the control of the thermostat.

Note that on all models the fan and the neon on the Turbo switch will
cycle on and off under the control of the thermostat – see ‘Thermostat’.

Ioniser Model 3088TA

The ioniser operates all the time that the heater is connected to the
mains supply.

Principles of ionisation :

• Restores the natural balance of the air.
The physiological and psychological effects of negative ions are well
known, including increased alertness, easier breathing and better
sleep.

• In addition to the direct benefits, the stream of negative ions will
charge dust, pollen, bacteria and smoke particles. These charged
particles are then attracted to the surfaces in the room and
deposited as fine dust, leaving the air cleaner, fresher and healthier.

• The output from the ioniser will be combined with the output of the
heater, with or without fan boost. The fan increases the volume of
air affected by the ioniser, enhancing its range and increasing the
amount of pollutants from the air.

• In warm weather, the ionised air can be circulated by using the
turbo fan only – see ‘Turbo fan models’.

Safety – overheat protection

For your safety, this appliance is fitted 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 sufficiently, 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 airflow 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.

Cleaning and User Maintenance

WARNING – ALWAYS DISCONNECT FROM THE POWER SUPPLY
BEFORE CLEANING THE HEATER.
