Assembly and Positioning


WARNING The radiator must only be operated with the wheels and castors fitted and in the upright position.

The castors must be fitted to the control panel and between the last and second last fin on the opposite end, as shown in Fig.1.

To fit the castors, turn the radiator upside down on a carpet or other soft surface to avoid damage


Locate the wire clamp (A) and remove the winged nut (C). Insert the non threaded end of the wire clamp into one of the holes in the castor plate (B) as shown. Feed the threaded end of the wire clamp between the last and second last column fins ensuring the wire clamp wraps around the column body (sump). some manipulation of the plate and clamp will be required. The threaded end should then be passed through the castor plate and secured using the wing nut.

To fit the castor to the control end, position the castor plate in position and secure using the wing bolts (D). there are guides to ensure the correct positioning and orientation of the caster plate.

Return the radiator to the correct orientation so it rests on the castors. The product is now ready for use.



POSITIONING THE HEATERSelect the position for the heater ensuring there is clearance from any furniture and fittings of at least 300mm above the heater and 150mm each side and 300mm from the control and end panel. We recommend maximising the clearance where possible.


Models & General Information


GENERALThe radiator is designed for operation on an AC electricity supply, and is suitable for use in domestic dwellings and similar indoor locations.

The radiator is fitted with castors and a handle for ease of movement. A rotary selector switch provide the ability to choose an available heat output and an adjustable thermostat enables the room temperature to be controlled accordingly. It is supplied with a cord and plug and is ready for use once the castors have been correctly fitted.

IMPORTANT – OBJECTS OR CLOTHING MUST NOT BE PLACED ON THIS HEATER.Before using the heater ensure that all warnings and instructions have been read carefully.To activate the heater simply plug it in. Neon indicating lights located at the controls area will illuminate when the appliance is plugged into the mains. This indicates the appliance is energised and ready for use.


ThermostatThe Thermostat, see Fig.3 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 required setting 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° to help protect against frost.

Note – Should the heater fail to come on when the thermostat is at a low setting, this may be due to the room temperature being higher than the thermostat setting.

Heat Selector Switches (see Fig.3)Heat selection is provided via a rotary switch offering four settings. The heat output can be altered to suit the application, conditions and for improve the economy of operation. Available output options are as follows:


Timer Models

DIGITAL TIMER (Tie models)

IMPORTANT: Remember to observe all safety warnings when operating the heater on auto setting, either attended or unattended.

The timer allows you to select ‘AUTO’ or ‘MAN ON’ by pressing the ‘MODE’ button until the required MODE appears at the bottom of the timer display.

‘AUTO’ MODE allows the heater to switch ON and OFF according to a set 24 Hour program period (see ‘Setting Programs’ section below).

‘MAN ON’ MODE allows power to the heater uninterrupted by the program settings.

Key LockIf ‘ENTER’ and ‘MODE’ are pressed within 1 second, the keys will be locked. The user will know the keys are locked as the lock symbol ‘ ’ will be displayed on the top left hand corner of the screen. To unlock the keypad, press ‘ENTER’ and then ‘MODE’ within 1 second.

Initial OperationFor initial use, plug the heater into a regular household power point and turn the power on. The timer is now ready to be set up for use.

Setting Current Time

  1. Hold the ‘PROGRAM’ button until the clock symbol appears on the screen. The user can now set the clock.
  2.  The hour digit will flash. To adjust the hour use the ‘-‘ & ‘+’ buttons. Confirm the hour digit by pressing ‘ENTER’.
  3. Once ‘ENTER’ has been pressed the minutes will flash. To adjust the minutes use the ‘-‘ & ‘+’ buttons. Confirm the minute digit by pressing ‘ENTER’.
  4. The timer now returns to the default display.
  5. To reset incorrect time, repeat previous steps.

Once the correct time is set, a total of four ON/OFF time programs can be set for operation.

Setting ProgrammesPress the ‘PROGRAM’ key to set the programs.You are now setting the programs starting with P1 ‘ON’.


  1. To set the hour use the ‘-‘ & ‘+’ buttons. Confirm the hour digit by pressing ‘ENTER’.
  2. To set the minutes use the ‘-‘ & ‘+’ buttons. Confirm the minute digit by pressing ‘ENTER’.Note: The minutes can only be set in 10 minute blocks in programme ‘MODE’. SETTING P1 OFF TIME
  3. To set the hour use the ‘-‘ & ‘+’ buttons. Confirm the hour digit by pressing ‘ENTER’.

At any time while programming the timer you can press the ‘PROGRAM’ button to exit to the default display.Note: If the ‘ON’ time is the same as the ‘OFF’ time the appliance will ignore the program.

The Advance FunctionWhen in ‘AUTO’ MODE, if the ‘+’ button is pressed for longer than 2 seconds the programme will ADVANCE to the next setting programmed and will only revert back to the program when the subsequent programme time is reached. When the ‘ADVANCE’ function is running the ‘ADVANCE’ segment will be displayed on the LCD screen. If the ‘-‘ button is pressed when the ‘ADVANCE’ programme is running the ‘ADVANCE’ feature will be automatically cancelled and the programme will run as normal.

Note – Timer Memory Back Up Batteries – Once the heater has been left plugged in with the socket switched on for at least 72 hours the timer’s memory back up batteries will be fully charged.

Once the timer batteries are fully charged, if there is a power cut or if the heater is disconnected from the mains for less than six months, 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 six months, 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 the AUTO MODE again.


Setting the time of dayTo 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. 5. The 24-hour clock is used ; e.g. time shown for 4 pm is ‘16’ (16:00hrs).

Operation ModesSet the operation mode using the slide switch on the timer – see Fig. 6:

Position I – Manual operationThis setting allows power to the heater uninterrupted by the timer settings. The heat selector switch and thermostat will control the output (see ‘Controls’).

Position – ‘Auto’ operationThis setting allows the heater to be switched ON and OFF according to a set 24 hour program period.

DO NOT disconnect this heater from the mains supply unless it is being taken out of use (e.g. in summer or for storage), otherwise the timer clock will stop.

Setting the ‘Auto’ ON and OFF times

To set the timer :

  1. Using your finger 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. 6. Each segment pushed in switches the heater OFF for that part of the hour. All other segments will be ON. For example, Fig. 6 shows the timer set to switch the heater OFF between 11pm and 1.45am
  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.

Note: each segment represents 15minute period


Safety Features
